Bullet Most of us usually see on a color, but in fact, there are many kinds of bullets color, such as green, red, black and white, which is why? Many of the original bullet types, uses are not the same, in order to facilitate the difference in the battle to identify, manufacturers will be at the tip of the bullet painted different colors. Ordinary bomb warhead not painted or coated with silver (steel core bullet). It is a package consisting of copper or lead sheath is made of a steel core. It is mainly used to animate killing enemy targets. Anatomy of tracer bullets coated with a green bullet, the bullet is the lead center front, middle flare pipe, built with tracer agent, ending in a fixed ring to prevent outflow of tracer agent. Combustible ingredients tracer agent, oxides and adhesives, so it flying at night, always dragging behind a bright light. Tracer primarily to display trajectory, indicating that the target correction shooting. Incendiary warhead painted red, the front fitted with internal combustion agent warheads. Warhead middle of a steel core, rear mounted tracer agent. It is built, "fire", mainly used to ignite flammable substances, such as grass, wood camouflage facilities and ammunition depots, fuel depots, vehicle assembly and other enemies. With it some of the fuel tank made of thin metal, such as target shooting, also received good results. Armor-piercing incendiary warhead painted black (some painted black and red circle). Its hardened steel core is made of high carbon steel. Outsourcing the lead bullet core _set_s. Combustion agent warheads mounted on the inside of the front, and now produces more than warheads mounted on the back end. It is mainly used to shoot enemy tanks and light armored targets. Burning tracer bullet piercing painted red, painted purple top, mainly for some large-caliber machine guns to use. It is basically the same structure with the incendiary, but the back end in the warheads fitted tracer agent. It brings together the expertise of various bullets, ballistics both directions, but also piercing, while arson, mainly used for long-range air and target shooting. Bullet Instant bomb warhead types of anatomy and painted white, middle warheads packed with explosives, dynamite bomb with the front cap, penetration tubes and detonators, explosives fitted behind the flare. It is a large-caliber machine gun for anti-aircraft fire. When the bullet hit the target, due to the effect of penetration tubes and detonators and detonating explosives. Bullet in the barrel because no obstacle, it will not explode. But when the bullet from the gun, did not hit the target or obstacles, at a certain time, the flame will ignite the tracer agent inside the black medicine to make explosives. Short shells (Hollow Point) is generally known as the expansion of warheads, a process commonly known as the mushroom of (Mushroom), because the warhead after the expansion, it looks like a straw mushrooms, as head of a small body. In the United States it is legal bullets, especially used in hunting is the most popular warheads. Some states also requiring the use of such warheads when hunting, because they are more up to a deadly bomb effect, reduce the suffering of animals. Short and generally known dumdum bullet (Dum-Dum) of different burst warheads, missile into the target body is short fragmentation should not, of course, if you hit the bone, nor is it will not happen. But in short, it will not be like dumdum, the purpose behind the design is to hit the target, fragmentation becomes countless small shrapnel. The so-called dumdum bullets, the earliest in 1896 the British in India Damm arsenal, the official name is "Dum Dum Mark 2 Special", caliber .303 British, 7.7mmX56. Its lead exposed at the tip of the heart, the head looks and modern soft shells same. Due to restrictions of the Hague Convention on international war production. Britain has the Boer War in South Africa (Boer War, 1899-1902), the use of too short rounds.

Design Principles
No matter what style of bullets, which are made projectiles, cartridges (shells), propellant and fire cap (primer) composed of four parts. For the bullet, whether it is used for what purpose, the international generic drugs are mostly smokeless launch: smokeless powder can be divided into (a single base, double base, third base) (the main component of nitrocellulose), firearms and more with a single base propellant. For different firearms with shells have different requirements. Such as: pistol-speed multi-porous single-fired base drugs. Rifle with light and surface passivation using the particle-hole single-base medicine. By the end of the fire: the fire-hole, angry anvil and firing agent. Its role is to produce a flame firing so quickly and really ignited propellant. When firing, the firing pin and firing agents hit by the impact of the anvil and angry, the flame ignited propellant through the fire-hole. When transmitting, the firing pin inspired fire cap (primer). Bottom rapid fire burning propellant ignition cartridge (bullet) inside the burning propellant produces instantaneous, while producing high temperatures and pressures, the projectile (bullet) from the drug extrusion barrel, then the projectile at high pressure propellant generated driven forward move by rifling extrusion, resulting in the rotation, was eventually launched the chamber.

Bullet, propellant, cartridge cases, primers consists of four parts warheads, but it can produce far so simple at first glance, you need to work and coordinate between different manufacturers. General domestic bullet manufacturers only produce warheads and cartridge cases, primers and propellants need to outsource, and then assembled into finished products, large bullet manufacturers there EED used on special Pyrotechnics workshop production at the end of fire and other bullets, but Propellants also provided by specialized manufacturers. Let us together to explore the difference between reality and movies, according to the manufacturer bullet, bullet shells until the full sequence assembly and packaging, to see one of the most common Type 56 rifle factory to go through before finally what "tempered."

Warhead manufacturing
Warhead components are killing bullets on, in addition to size, high accuracy requirements, it also must be a sound structure and shape, in order to ensure good penetration of the target and damage effects. Types of warheads are many different types of warheads which are not the same process, "Lord of War" titles to the already installed on the finished bullet casings, no bullet to show the process of processing. 56 common type of jacketed bullet, lead and steel core _set_s of three parts, each part is separately manufactured, assembled after passing inspection warheads. The main components such as bullets bullet shell, cartridge cases, primers and flare shell and other shell shape were tested with the end of the goblet, its production process need to use bullets most widely used technology - "Extension Processing" producing parts of different shapes and thickness, as long as the changes to the shape and size of the mold. Since the production of the cartridge requires high accuracy and consistency characteristics, the size of the mold parts is basically ensured by and large batches, if the deviation will cause a lot of waste occurs, and therefore the manufacture and installation of the mold has high demands, each link must strictly promptly remove unqualified and adjust the machine. Domestic bullets generally used as a copper-clad steel bullet shell (or jacketed bullet) of rough material, brass or abroad have done blank round. With copper-clad steel shell for the rough material warhead production process: cutting the pick cupping → Appearance → annealing, pickling extension → → → crowded mouth and sharp red flared. Annealing treatment is to eliminate rough machining work hardening due to severe deformation of pickling is annealed to remove oxide scale rough surfaces. Extension from copper-clad steel processing makes loading and unloading or round steel spoon into a smaller diameter, wall thickness, SM extension process once processing small amount of deformation, is now widely used in multimode extension, in a stroke that a relatively large amount of deformation can be obtained. Chong pointed bullet shell production is another special stamping process, the purpose of the size of the projectile out of the tip of the arc. As the bullet shell after processing the tail to leave a margin, you need to be removed with a knife or with a squeeze to remove the excess part of the die, which can also punch in the face oblique tail bullet shell flaring, easy to assemble bombs after the heart, improve production efficiency and product size consistency. This part of the process of the former Soviet Union four times require red tip, squeeze and flared mouth are two processes, and the use of previously crowded mouth incision process more cumbersome. Domestic production of 56-style rifle in the process of gradually accumulated to form a _set_ of processing methods suited to China's national conditions, the number of bullet shells red tip to the existing two times implied by the previous single-mode to multi-mode extension. After the above process and inspection by a qualified warhead shells can be used to assemble the warhead. The production of multi-mode warhead casing extension process three common drawing die: A mold is integrally molded with the guide portion, wherein the mold is a, b is the outer mold, the mold can be divided into four parts (a portion of the guide 2 is a tapered portion, the cylindrical portion 3, the bottom of the inverted cone portion 4), usually with carbide manufacturing mold, the outer mold tool steel. This mold structure is simple, the mold can also be applied to the mold used; B is a combination of the mold die with a guide portion, which is a guide ring, b is in the mold, c is the outer mold, the mold used in place of the guide ring A guide portion, which is characterized by a relatively simple process; C without a guide portion of the mold die. For the extension of the lower die or die. Another common type of warheads in the 56 main parts are steel core, the use of low-carbon steel, except for the purpose of saving the lead, but also can improve the penetration force of the projectile. The first production of its steel core bullet head 56 is flattened cone, the mold production loss, later changed to flat arc, greatly improving the die life. Steel core production processes generally: cold drawn round shaped red → cutting → → → school roll light volume. Cold drawn steel bar which is generally carried out in a steel mill, and then use the punch cold cut material. The purpose of light is conducive to playing the roll center of the assembly, but also the need for the size and quality of the school amount, after passing the steel core to enter the next process. 56 style common among jacketed bullet with a lead sheath and a steel core, and its role is to slow down the wear and tear on the rifling of the projectile, while the steel core and jacketed tightly. Because lead is soft, and a low melting point and recrystallization temperature, the processing does not produce cured at room temperature, and therefore manufactured using extrusion. Further deformed due to the lead member in the assembly, thus affecting the symmetry of the warhead, the density and the center of gravity position, etc. Therefore, good control of the dimensions of the parts of the lead member is a difficult processing. Ordinary playing lead sheath tip often leave a small cylinder or cone, its purpose is to assemble more easily when the tip of the bullet shells filled so tightly within various parts of the warhead. 56 common type of heart Bouncing general processing steps are: molten lead → → squeeze lead in multi-station punch extruded lead sheath → steel core pressed into a lead sheath → drying → visual inspection. Squeeze lead is the preparation of a good lead-antimony alloy block squeezed into the lead right size, and disk backup on the rollers. In the multi-station punch extrusion process is the most important piece of lead bullet steps lead _set_s the shape is more complex, and the wall thickness of the dimensions and have strict requirements, so the lead sheath generally 2-3 times to squeeze through pressure to shape, but only after the whole pellet core material in the mold under a squeeze can be formed. Pressed into the steel core of this process difficulties lead sheath is strictly controlled steel core into the depth of the lead sleeve, too deep or too shallow will affect shooting accuracy. The purpose of drying is to remove the soapy water lubricated lead extrusion applied to prevent rusting steel core. Bullet shells commonly used in the production of red tip mold (1 outer mold, mold 2). A die is a die punch tip, B-mode for the end of the previous sharp punch die, C sharp punch die mold for the end times. General tip bullets bullet shell mold can be washed only with A and C are two, but sometimes in order to ensure that the size of the bullet tip of the arc, but also use B-type punch tip die. A, B-mode top of the hole, which will help lubricating fluid and air out, ensuring bomb tip size. Red tip of the most prone to failure was wearing a red rough, which is plastic, die and punch processing design material and a deformation of the size. So when the first punch tip radius of the punch tip is relatively large, and the red tip height is not high, can effectively avoid wearing red rough. [Warhead assembly methods] Missile warhead assembly is loaded into the heart or other parts turn warhead shells, shells and warheads tail processing, so that the quality dimensions and the process of drawing warheads reach requirements. Assembly quality directly affects the accuracy of bullets fired. Domestic production of 56-style common in the long process of bombs, warheads worked out a complete _set_ of assembly methods to improve the fire intensity: One of the important dimensions affecting shooting accuracy stringent requirements, other sizes category management, were assembled into warheads, depending on tolerance; 2, relying on molds and reasonable process to ensure symmetry warheads; 3, the inner parts warhead assembly tightly, eliminating loose and gaps. Type 56 ordinary warhead assembly process is: bomb → tail cone pressed into the heart of the Ministry of preload → → curling tail cone bottom portion forming over the Trail → → → roll groove dimensions school weighing → Appearance → amount seized election. The main assembly equipment is multi-station automatic punch. Ministry preload tail cone is pressed into the cylindrical portion of the heart bomb warhead casing pressure after a certain length tail cone, creating conditions for playing curling and forming the bottom portion of the tail cone, while preventing heart bounce bombs broke out tooling equipment. In order to ensure concentricity warhead warhead tail cone and the cylindrical portion, usually with a punch to push the bullet into the head so that the tail cone mold finishing touches finishing cone warhead after the final pressure process can be turned 180 degrees into the finishing cone step of entering the rear crimping step also turned 180 degrees. Tail cone shaped tail cone is warheads and bombs after the end of nest curling final shape after bullet after this procedure, in addition to the diameter of the cylindrical portion of the outer ditch and roll the rest is basically in line with requirements of the drawings. Diameter over warhead is intended to eliminate the cylindrical portion of the bullet assembly process "hoop effect" phenomenon, while the upper cylindrical portion in the longitudinal direction of the warhead size consistent internal parts binding closer warhead. Diameter warhead had to be sent after the roll tight mouth ditch, 56 ordinary playing style trench mouth tight triangle, is now separate from the roll groove machine improved to roll groove machine with bullet assembly machine interaction, directly over the path is completed warheads send roll groove machine roll groove is finished processing out of the warhead. Type 56 ordinary warhead production and assembly processes. Where A1 → A3 steel core processing, B1 → B5 to lead sheath production process. A4 is pressed into the steel core lead sheath, C1 → C3 is the next round with a bullet shell material manufacturing process. D1 → D2 is manufactured with copper-clad steel bullet shell process, C3 → C4 to squeeze the glenoid, D2 → C4 as cupping, C4 → C8 molding process for the bullet shell, A5 → A9 as warhead assembly molding process. Diameter warhead had to be sent after the roll tight mouth ditch. Finally, the processing step warheads for: school size amount tumbling → → → Appearance weight correction amount seized election. If special warheads, but also for playing the last tip coloring. Just roll the surface to remove oil warheads and oxide film, so that the bullet surface clean and bright, easy to assemble bombs seized and the entire election. Tumbling machine is generally driven by the motor rotating wooden drum, built confetti or rice husks, etc., together with its bullet in the barrel rolling friction is polished. Size correcting the amount of 100% of the length of the bullet test, the diameter of the roll diameter and the height of the groove opening, the size of the tail cone sampling only do so on, as long as it is appropriate to adjust the machine and the mold, these dimensions difficult problem, but due to manufacturing length warhead deviation of error accumulation may be relatively large, must be 100% inspection. Its test is done on a machine the size of school capacity, school capacity by adjusting the size of the blade automatically exceed the allowable error range warheads excised, and sometimes also on the inspection to ensure the accuracy of the _select_ed qualified warheads sampling, hand-measure sizes. Weight correction amount is too light and weighing machine removed too heavy warhead, and classified by weight for qualified warhead assembly plant bombs sent to the assembly, within the error range for the severity of warheads, propellant can be guaranteed by appropriate changes bullet performance is essentially the same, in order to avoid excessive waste generation. The last step for the appearance of the pick, which is the largest warhead production of a labor-intensive process, because some of the ills of warheads such as surface line marks, wrinkles, rust, grease, fingerprints, playing at the end crush, roll groove defects such as incomplete unable to identify with the machine, choose to rely on visual inspection. General to develop a specimen from the factory, more than specimens that failed. The appearance of the pick warhead generally look the pick machine, the machine's purchase funnel to be seized election to fill warheads, warheads fall was driven by the screw is rotated from the funnel in order to observe the various parts of the warhead, found substandard Excluding hand, qualified warhead was taken to collect the screw box. When the pick warhead operator must wear a mask and gloves, and timely replacement. At this point it really warhead processing is completed, the final qualifying warhead would go to conduct a comprehensive quality checks, which can be seen bullets manufacturing complexity and rigor.

Manufacture of shells
子弹 弹壳的制造
The bullet casings are the most important part, it is used to contain propellant and warheads and end the connection with the fire, but also to withstand the gas pressure transmitter power of gunpowder and firearms automata. China is currently manufacturing 56 rifle bullet casings ordinary materials into two copper-clad steel and deep drawing quality carbon steel and abroad as early the brass material. Domestic 56 shell casings from brass to copper-clad steel and painted steel, copper resources for such a country is the lack of strategic significance, not only cost savings, while avoiding the potential risks of imported copper materials wartime interruption. Domestic processing technology have significantly improved, such as the current steel shells in the production process can be done Implied processing without the annealing, a processing rate of over 85%, shell Implied reduce the number of more than 70%; equipment is from the previous single-station, single punch, a low number of revolutions to the current multi-site, multi-punch, high speed, greatly improving the efficiency of production; while rough improvements also significantly improved material utilization, cost reduction effect is very obvious. The current domestic use of two different materials as shown in the production process line shells 12 and 13, shown in Figure 12 using a copper-clad steel, deep drawing quality using 13 Carbon Steel. The former can be seen in Figure production process simpler, but the copper-clad steel prices relatively expensive, and are plates, utilization is relatively low, only copper is still being consumed, and are difficult to recycle. Using deep drawing quality carbon steel rod material, although the complexity of the production process, and the mold and machine requirements are relatively high, but not copper, the material cost and high efficiency, the economy is good, more suitable conditions. Implied bullet mold production commonly divided into A, B, C three categories. A 1 - die _set_s 2 - lead laps 3 - within the mold, the mold used for the extension of this mode; B 1 - die _set_s, two - in _set_s of three - the mold; C 1 - die _set_s. 2 - mold. B-mode and C mode generally used for lower mold, the mold is generally implied carbide die manufacturing, general manufacturing with the remaining carbon tool steel. Careful comparison can be found in the two process routes in addition to processing into steel spoon of different processes before, the rest are mostly the same. The difference is that the carbon steel prior to phosphating and extension to a more saponification processes, primarily because there is no processing of the lubricating layer of copper such as copper-clad steel on the surface of the blank. Domestic production of 56-type copper-clad steel shells, generally washed down with 7 die machining steel material cupping spoon, cutting and cupping completed in a single machine and a stroke, and because it is multi-punch, higher productivity. The use of carbon steel bars for machining steel Meng little more complex, generally the first punch of the bar with a cold cut into small pieces cylindrical blank, then both ends of the pier level, after annealing and phosphate, saponification, to a closed mold inside, by extrusion processing technology into steel spoon. Due to its large deformation, processing power and higher temperature, the mold is also high. In the production of casings basically using anti-extrusion to manufacture steel spoon, the advantage is small squeeze pressure molding precision. Processing Gang Yu, the two kinds of production line are processed the next extension, the same is to be annealed once, but the copper surface after steel steel spoon extension without special treatment, and carbon steel steel glenoid surface is required phosphate, saponification, but manufacturers have not treated directly two arguments. Implied in the domestic processing is widely used in casings our unique multi-mode extension technology, so a large deformation processing, just like 56-style bullet Extension 2 and wall thickness can reach the required height. After processing the steel cup port extension portion is generally not very smooth, and the height is relatively high, generally take the excess part of the mouth portion is removed, typically by extrusion with two ports and the cutout. Squeeze the mouth is generally used in large-caliber shell casings and 56 casings mouth style thin for incisions to remove the mouth margin. Incision is usually done in the cut plane, there are already four parts simultaneously cut incision machine, high production efficiency. After the mouth but also for playing rough cut concave shells peaceful end, the end of the initial formation of the former fire room, fire station and fire chamber mouth rounded bottom, which eventually formed the size of various parts of the bottom of the fire chamber, and to ensure a certain degree of accuracy, but also In the pressure on the underside shells corresponding plant number, year and other markers. Since the bottom of the shells have a high strength to withstand the forces of launch time, playing the part of the concave and flat generally no longer annealing. Red fire-hole as a separate process, usually by a dedicated fire-hole punch and punch mold is completed, of which two punch tiny red head pin, next to the fire station rushed to the symmetry of the two fire-hole, to improve the combustion rate. The next step will enter shut. Before the bullet Both materials shall be shut after burning mouth, i.e. the extension processing through the mouth portion of the glenoid steel annealed shut when the deforming force can be reduced to prevent cracking. Type 56 shells shut take "pull mouth" method, surface treatment after shut to prevent the lubricating fluid so that the primer interior rust. Next procedure to flush the mouth and underbody, Qi mouth mouth to remove the excess part of the shell, shell casings guarantee total length of the vehicle is pulling the car out of the shell hook slots, both done on the same machine, respectively, by Qi mouth knives and underbody Turning the knife from forming. After a homogeneous population, its size shells vehicle drawing requirements have been met, thus shells machining completed. The next step for the school capacity, which is important in the production of a bullet mark on the shell casings important dimensions generally amount to 100% of school conduct, eliminate substandard goods, tolerance for repairable items, after rework, inspection after the same Batch processes bullet hair down. 56 bullet-style machine using progressive correction amount the amount of school, 9 sizes can be amplified by mechanical principle of the bullet length, diameter of the bottom edge, the depth of the fire station, the end of the fire chamber diameter, the thickness of the bottom edge, mouth diameter and full-width size in turn the amount of school. Qualified bullet holes still need an optical inspection process aimed at removing did not return fire or fire-hole to plug holes in shells. The amount of qualifiers for the school, if it is copper clad steel casings, but also on the hook tank shell casings pull phosphating and painting, if it is steel shells, then the phosphate electrophoretic coating. After the completion of the election process enters appearance inspection, in line with the pick warhead operations and methods, but also driven by the pick machine, then manually check election. So far all the processing side casings came to an end, but also on all aspects of size and shooting capability to conduct a comprehensive sample testing bullet, if you find a problem, you need to double the reinspection, the acceptance of the shells before assembly into a bomb. After such a complex production process, just to get a qualified warheads and shells, bombs below in order to carry out the whole assembly. Leftover material after the next cold-rolled brass, rod blanks compared to their low material utilization

To bomb assembly
Bullets into the bomb assembly is the last step of the production process, but also the quality of the final decision is good or bad bullets important process, in particular related to the assembly and propellant EED, the slightest negligence, it will cause a lot of waste or material safety accidents, so this stage production requires special attention to the quality and security. Cartridge assembly generally have anti-knock performance in a small room isolated production, launch and other drugs in the room can not store too much pyrotechnics, a bomb can not be too much accumulation, should be promptly transported to the next process, machine must promptly wipe, wipe spilled propellant or other pyrotechnics, etc., to prevent accidents. 56 domestic assembly ordinary rifle bullet can generally be divided into two parts, the first step is to install primers, school capacity, dispensing and coating inside the mouth, the second step is loaded propellant, warheads and warhead tight mouth, etc., then School capacity is down, inspection, sealing and inspection election of bullets. Bullet primer is typically mounted on the upper end of the fire combination machine completed, the completion of such a device can be continuously loaded primers, school capacity, dispensing and coating inside the mouth processes. Depth loaded primer based on different _select_ion criteria and have some differences, some with bullet bottom edge thickness position, loaded primer accuracy depends shells bottom edge machining precision, the other is a primer red and fitted bottom fire dies to positioning accuracy depends on in precision punch and die, compared with the way in terms of higher accuracy, made 56 ordinary bombs that take the latter type. After the primer Bahrain needs to be calibrated depth loaded amount, excluding load too deep or too shallow shells, the amount of correction methods, including mechanical and electrical calibration correction amount the amount of the former is still a lever amplification principle, the latter is the use of displacement of the punch relative amount of electromagnets to school primer into the depths. After school the amount of fire and bullet casings between the bottom seal lacquer coating, known as the "glue", the purpose is to make long-term storage of bullets will not moisture deterioration. Its two ways, one is all painted on the bottom surface of the fire, another fire and just painted on the bottom end of the fire chamber seams. The former process equipment is simple, the disadvantage is a waste liquid paint, and sometimes a way to paint will flow to the bullet body, affecting the appearance, in addition to shedding sometimes clog firearms hit film pinhole, so after using homemade bombs and more. Generally used in anti-corrosion sealer paint, varnish or preservative mixture of nitro lacquer and shellac, sometimes to distinguish between species but also will paint bombs dyed different colors, such as domestic 56-style flare green paint coating the bottom part of the whole fire, according to an ordinary bomb manufacturers of different ingredients and seal paint color is also different. After dispensing the primer coated bullet Jibei sent within the mouth, its purpose is to ensure the tightness of bullets, bullet and shell casings to prevent moisture from binding sites into making propellants and primers deterioration. The method is in the inner wall of the cartridge case mouth coated with a special paint some viscous bitumen, a width of 2 to 4 mm warheads loaded shells, warheads squeezing the bottom of the bullet and shell casings at the bottom of the inner wall formed around a dense ring. After the painted shells dry mouth is generally a period of time you want to make the film surface to harden, and will not stick hanging propellant medicine tablets, while not completely dry, otherwise it can not form a complete seal. After each bullet above process, after passing inspection rushed into the bomb assembly plant. Bullet shells assembled into general use and assembled machine, assembled into a bomb should meet five conditions: 1, stable propellant performance, no impurities, and can use correctly in batches; 2, charge the correct amount; 3, pulling elastic uniform; 4, the length in the predetermined range; 5, shells and bombs can damage the surface formed by the assembly. Bullets before assembly, you need to first pass warheads and shells loaded into the machine pallets, the need to sift into the propellant storage tanks. When first loaded propellant cartridge assembly, and the amount of propellant loading requirements are very accurate, since the actual production can not send bullets are accurate weighing every good after loading propellant, the actual industrial production volume is determined according to a quantitative method charge amount can be adjusted with a slider called "drug gate" through which charge is increased or decreased and thus serves to adjust the volume of the amount of charge on the cartridge assembly of the machine, the machining accuracy and surface finish of the device are high, the production process also requires constant adjustment and cleaning. Generally shipped from the manufacturing plant gunpowder propellant test equipment shot through experiments to determine the exact batch of drug loading dose needed, adjust the door on the machine drug loading dose to ensure accuracy. But also for "probe drug" propellant installed, mounted or less tainted prevent the occurrence of propellant loading. Can be sent to the next station after passing warhead assembly. Warhead is generally installed in bullet mold assembly is completed by a red dress warheads, some bullets in order to improve the stretch to pull even a "cover mouth", even though the bullet cartridge case mouth rolled into tight mouth trench, 56 bullet-style general assembly in bomb mold processing an inward relative to the inner wall of the cartridge case mouth slope position, when the shells into the mold, and its mouth is pushed onto the warheads in the role of the tight mouth trench slope. Due to the use of the bullet inside the mouth can increase the pull-coated elastic, so there are grooves and tight mouth cancel warheads "cover mouth" bullet manufacturing processes in trend. After the bullets also assembled the whole shape of the weight and volume for calibration, called weighing Hop bore. This process is generally on the weighing machine to complete a total bore, and its purpose is to remove the weight and the full-width does not meet the requirements of the bullets. 56 ordinary playing style after assembly is completed, must be weighed Hop bore 100 percent inspection, remove the defective products must be promptly destroyed, but the waste shells available parts to re-use classification. Eligible also apply a test cartridge seal around the mouth portion of the paint bullet, also called mouth coated to further enhance the sealing performance of the bullet, the bullet is copper-clad steel is exposed to the mouth portion of the steel bullet part played rust effect. Not treated as a single port step, generally in combination with co cartridge bore weighing machine, after weighing and is fed together coated bullet bore outlet means, when the bullet is driven wheel is rotated while the rotation The shells painted mouth round seal lacquer painted mouth, and then the next rounds of ammunition to the mouth of the bullets coated onto a rotating screw naturally dried and fed carton. In order to improve the surface finish of bullets, bullets go through a tumbling process, specifically with the tumbling warheads and shells similar. At this point all the bullets processing and assembly work was completed, and then the appearance of the pick, and the aforementioned bullet, bullet casings seized choose the same appearance, but also rely on manual operation, but the test is relatively stringent. After removing the pick and will produce a finished bomb into four broad categories: 1, the yield, which qualified; 2, repairable items, after the repair with the same batch of bullets destined for packaging; 3, ultra-poor products, samples ills extent than the allowable range, but can still be used, but under normal circumstances may not be used to fight with bombs; 4, waste, recycling propellant after the general open and available parts such as warheads, can not use the accumulated to a certain amount in the future destroyed. After the pick this road last pass, a sparkling new bullets considered officially "released."

Packaging and acceptance
Packaging is the last step of bullets bullets before leaving the factory, although this is not much relationship with bullets manufacturing itself, but has a great impact on the performance of long-term storage as well as transportation bullets, ease of use, it must not be taken lightly. 56 military-style bullets bullets and other domestic as commonly used metal cartridges plus wooden box packaging, each chest contained two Tiexia. China's production of 56-style bridge with ordinary bombs into two folders and folders without a bridge, with bridge clip is 10 rounds of bullets packed in a folder on the bridge, then 30 rounds packed into a brown paper bag, and then into Tiexia, 550 rounds per box, carton 1100 hair clip with no bridge is 20 rounds of bullets per minute or 25 rounds loaded into a paper bag, and then into Tiexia, 720 per Tiexia hair, hair carton 1440 . Packaging bullets Tiexia general use galvanized sheet steel 0.5 mm thick with double-bite process made necessary when using the accompanying early Tiexia open "key", more inconvenient, the latter method is to open a variety of Tiexia improvements. Packing boxes of bullets with lumber and plywood (all early wood) to suddenly shoots bite molding, plus nails fixed, body surface printing, including bullet type, name, material, quantity, propellant batches, GW, etc. and so on. After packing bullets packaging process completed. Although the production and packaging of bullets have been completed, but that does not mean they can be shipped immediately, before that you must get a "pass", that is, by the Mill military representative of all relevant properties of the final bullet to conduct a comprehensive inspection. Generally based on the number of batches and to determine the number of random testing, a lot of its content, including the appearance of general acceptance, size and weight of the test, pull stretch, loading dose, bullets tightness, painted steel casings paint finish quality inspection, bullet shock test, test firings, which also includes bullet muzzle velocity, maximum chamber pressure, precision bullets, bullet burst test and so on, but also for special armor-piercing bullet, burning, and other properties of the tracer was measured, and the determination of the strength of shells, firearms action Flexibility and testing of packaging quality. When these tests all pass through or later, the entire production process bullets considered the end of a real sense, you can order the unit and sent to the factory, to accomplish their ultimate fate as bullets.
