38-433: The weapon was unique, in that it is designed to be folded into a box shape, which can be unfolded and made ready to fire in a matter of seconds. When folded, the size is about the same as a cigarette carton, and the appearance is deliberately similar to an old-fashioned metal commercial radio. The ARES FMG can be folded with its 20-round UZI magazine loaded. A 32-round magazine was also available, but its use prevented folding

76-415: A machine press or stamping press , blanking, embossing, bending, flanging, and coining. This could be a single stage operation where every stroke of the press produces the desired form on the sheet metal part, or could occur through a series of stages. The process is usually carried out on sheet metal , but can also be used on other materials, such as polystyrene . Progressive dies are commonly fed from

114-422: A coil of steel, coil reel for unwinding of coil to a straightener to level the coil and then into a feeder which advances the material into the press and die at a predetermined feed length. Depending on part complexity, the number of stations in the die can be determined. Stamping is usually done on cold metal sheet. See Forging for hot metal forming operations. It is believed that the first coins were struck by

152-425: A folding stock, and a faux- suppressor to meet barrel length import requirements. The 9mm variant is classified as a pistol and therefore does not ship with a folding stock. Both variants are closed-bolt , blowback-operated semi-automatic firearms that vary substantially from originally manufactured MP 40s in internal operation, making them more of an affordable cosmetic replica than a faithful reproduction. Neither of

190-432: A physical tool. Stamping simulation allows any sheet metal part forming process to be simulated in the virtual environment of a PC for a fraction of the expense of a physical tryout. Results from a stamping simulation allow sheet metal part designers to assess alternative designs very quickly to optimize their parts for low cost manufacture. While the concept of stamping sheet metal components has traditionally focused on

228-449: A small loop that were used to hold the bolt in the forward position. The MP 38 receiver was made of machined steel, but this was a time-consuming and expensive process. To save time and materials, and thus increase production, construction of the MP 40 receiver was simplified by using stamped steel and electro- spot welding as much as possible. The MP 38 also features longitudinal grooving on

266-417: A smaller buttpad and shortened ejector. In 1941, Hugo Schmeisser designed the MP 41, which was, in reality, an MP 40 upper receiver with a lower receiver of an MP 28/II submachine gun. It saw limited service, however, and was issued only to SS and police units in 1944. The MP 41 was also supplied to Germany's Axis ally Romania. Later in 1941, rival company Erma Werke sued Haenel , at which Schmeisser

304-501: A technical point of view: During World War II, the resistance and the Allies sometimes captured MP 40s to replace or supplement their own weapons. The MP 40 was used for several decades following World War II by many countries around the world in armed conflicts. Some found their way into guerrilla groups such as the Viet Cong or African guerrillas. Its operators have included: During

342-548: A telescoping return spring guide which serves as a pneumatic recoil buffer. The cocking handle was permanently attached to the bolt on early MP 38s, but on late-production MP 38s and MP 40s, the bolt handle was made as a separate part. It also serves as a safety by pushing the head of the handle into one of two separate notches above the main opening; this action locks the bolt in either the cocked (rear) or uncocked (forward) position. The absence of this feature on early MP 38s resulted in field expedients such as leather harnesses with

380-472: A variety of lubricants available for this task. They include plant and mineral oil-based, animal fat or lard-based, graphite -based, soap and acrylic-based dry films. The newest technology in the industry is polymer-based synthetic lubricants also known as oil-free lubricants or non-oil lubricants . The term "Water-Based" lubricant refers to the larger category that also includes more traditional oil and fat-based compounds. Sheet metal forming simulation

418-468: Is a combination of the above methods done with a set of dies in a row through which a strip of the material passes one step at a time. The Tribology process generates friction which requires the use of a lubricant to protect the tool and die surface from scratching or galling. The lubricant also protects the sheet metal and finished part from the same surface abrasion as well as facilitate elastic material flow preventing rips, tears and wrinkles. There are

456-449: Is a technology that calculates the process of sheet metal stamping, predicting common defects such as splits, wrinkles, springback and material thinning. Also known as forming simulation, the technology is a specific application of non-linear finite element analysis . The technology has many benefits in the manufacturing industry , especially the automotive industry , where lead time to market, cost and lean manufacturing are critical to

494-481: Is located between the magazine housing and the Margolit pistol grip. The barrel lacked any form of insulation, which often resulted in burns on the supporting hand if it was incorrectly positioned. The MP 40 also has a forward-folding metal stock, the first for a submachine gun, resulting in a shorter overall weapon when folded. However, this stock design was at times insufficiently durable for hard combat use. Although

532-654: The Allied occupation of Germany starting in 1945, U.S. servicemen shipped home thousands of captured firearms as war trophies , including MP 40s. This practice required proper registration of automatic weapons in accordance with the National Firearms Act before they could be imported, but this was curtailed later in the occupation, meaning a relatively small number of civilian-transferable original German MP 40s remain in circulation and are valued at around $ 20,000-37,500 as of 2021, with some selling for almost $ 50,000. After

570-553: The Eastern and Western Fronts as well as armoured fighting vehicle crews. Its advanced and modern features made it a favorite among soldiers and popular in countries from various parts of the world after the war. The MP 40 was often called the "Schmeisser" by the Allies, after the weapon designer Hugo Schmeisser . Schmeisser had designed the MP 18 , which was the first mass-produced submachine gun. He did not, however, have anything to do with

608-551: The Firearm Owners Protection Act in 1986. There are several semi-automatic variants and cosmetic replicas of the MP 40 available for civilian ownership in the U.S. Beginning in 2014, American Tactical Imports began importing an MP 40 replica manufactured by German Sporting Guns GmbH chambered in .22LR , and since 2016 has also imported a pistol variant chambered in 9mm . The .22LR variant features an all-metal construction with period-accurate Bakelite furniture,

646-456: The 1880s. Stamping replaced die forging and machining, resulting in greatly reduced cost. Although not as strong as die forged parts, they were of good enough quality. Stamped bicycle parts were being imported from Germany to the United States in 1890. U.S. companies then started to have stamping machines custom built by U.S. machine tool makers. Through research and development, Western Wheel

684-496: The GSG-manufactured variants are compatible with originally manufactured MP 40 parts and magazines. Stamping (metalworking) Stamping (also known as pressing ) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using

722-621: The Germans found themselves out-gunned in short range urban combat which caused a shift in their tactics, and by the end of the war the MP 40 and its derivatives were sometimes issued to entire assault platoons. Starting in 1943, the German military moved to replace both the Karabiner 98k rifle and MP 40 with the new, revolutionary StG 44 . By the end of World War II in 1945, an estimated 1.1 million MP 40s had been produced of all variants. During and after

760-511: The Lydians in what is modern-day Turkey in the seventh century B.C. Until 1550, the hammering method of coins remained the primary method of coin-making. Marx Schwab in Germany developed a new process for stamping that involved as many as 12 men turning a large wheel to press metal into coins. In the 1880s, the stamping process was further innovated. Stamped parts were used for mass-produced bicycles in

798-418: The MP 36, and the MP 40 was a further simplification of the MP 38, with certain cost-saving alterations, most notably in the more extensive use of stamped steel rather than machined parts. The MP 40 submachine guns are open-bolt , blowback -operated automatic arms. The only mode of fire is automatic, but the relatively low rate of fire permits single shots with controlled trigger pulls. The bolt features

836-467: The MP 40 was generally reliable, a major weakness was its 32-round magazine. Unlike the double-column, staggered-feed magazine found on the Thompson M1921/1928 variants , the MP 40 uses a double-column, single-feed version. The single-feed insert resulted in increased friction against the remaining cartridges moving upwards towards the feed lips, occasionally resulting in feed failures; this problem

874-533: The commercial importation of complete machine guns was banned by the Gun Control Act of 1968 , MP 40 parts kits (the disassembled parts of the gun excluding the receiver tube) were imported and reassembled onto receivers manufactured in the United States by Charles Erb, Wilson Arms, and others. These remanufactured legally transferable machine guns, colloquially called "tube guns", are (depending on quality of construction and condition) generally valued at 50-75% of

912-401: The design or development of the MP 40, although he held a patent on the magazine. The MP 40's variants included the MP 40/I and the MP 41. From 1940 to 1945, an estimated 1.1 million were produced by Erma Werke . The Maschinenpistole 40 ("Machine pistol 40") descended from its predecessor the MP 38, which was in turn based on the MP 36 , a prototype made of machined steel . The MP 36

950-634: The end of World War II, many MP 40s were captured or surrendered (upwards of 200,000) to the Allies and were then redistributed to the paramilitary and irregular forces of some developing countries. The Norwegian army withdrew the MP 38 from use in 1975 but used the MP 40 for some years more. In particular, the Territorials ( Heimevernet ) used it until about 1990, when it was replaced by the Heckler & Koch MP5 . The MP 40/I (sometimes erroneously called MP 40/II )

988-729: The macro level (e.g. vehicle, aircraft, and packaging applications), the continuing trend of miniaturization has driven research into micro- forms of stamping. From the early development of micropunching machines in the early to mid-2000s to the creation and testing of a microbending machine at Northwestern University in the 2010s, microstamping tools continue to be researched as alternatives to machining and chemical etching . Examples of applications of sheet metal microstamping include electrical connectors, micromeshes, microswitches, microcups for electron guns , wristwatch components, handheld device components, and medical devices . However, key issues such as quality control, high-volume application, and

1026-467: The need for material research into mechanical properties must be addressed before full-scale implementation of the technology is realized. Metal stamping can be applied to a variety of materials based on their unique metalworking qualities for a number of applications across a wide range of industries. Metal stamping may require the forming and processing of base common metals to rare alloys for their application-specific advantages. Some industries require

1064-401: The price of original German MP 40s, as they do not have their historical background. As such, they are commonly used for recreational range shooting and WW2 historical reenactments , because the associated wear and tear (within reasonable limits) will not significantly diminish their value, as it would on original collectible examples. Manufacture of new tube guns ceased following the passage of

1102-498: The receiver and bolt, as well as a circular opening on the magazine housing. These features were eliminated on the MP 40. One feature found on most MP 38 and MP 40 submachine guns is an aluminum, steel, or Margolit (a variation of Bakelite ) resting bar under the barrel. This was used to steady the weapon when firing over the side of open-top armored personnel carriers such as the Sd.Kfz. 251 half-track . A handguard, also made of Margolit,

1140-468: The success of a company. Recent research by the Aberdeen research company (October 2006) found that the most effective manufacturers spend more time simulating upfront and reap the rewards towards the end of their projects. Stamping simulation is used when a sheet metal part designer or toolmaker desires to assess the likelihood of successfully manufacturing a sheet metal part, without the expense of making

1178-507: The underside of the weapon or the magazine housing with the supporting hand to avoid feed malfunctions. At the outbreak of World War II, the majority of German soldiers carried either Karabiner 98k rifles or MP 40s, both of which were regarded as the standard weapons of choice for an infantryman. However, later confrontations with Soviet troops such as the Battle of Stalingrad , where entire enemy units were armed with PPSh-41 submachine guns,

1216-415: The weapon. The original prototype was designed to use a World War II German MP40 magazine. The second prototype used UZI magazines and had a three shot burst mechanism as well. The weapon inspired a Russian, and a Ukrainian copy which are almost identical except for caliber, magazine and folding sights that were added. While descriptions of a fictional "ARES II FMG" exist on the web, the actual ARES FMG

1254-535: Was Chief Designer, for patent infringement. Production subsequently ceased on the MP 41. The MP 38 and MP 40 also directly influenced the design of later weapons, including the Spanish Star Z45 , the Yugoslavian Zastava M56 , and the semi-automatic German Selbstladebüchse BD 38 replica. Details of the MP 40 have also been adopted in other submachine guns, which otherwise differ significantly from

1292-526: Was a modified version of the standard MP 40 with a dual side-by-side magazine holder (for a theoretical ammunition total of 64 rounds), designed for special operations troops on the Eastern Front to compensate for the Soviet PPSh-41's larger magazine capacity. However, the design proved unsuccessful due to weight and reliability issues. Authentic versions, in addition to the dual mag magazine well, also have

1330-706: Was able to stamp most bicycle parts. Several automobile manufacturers adopted stamping of parts. Henry Ford resisted the recommendations of his engineers to use stamped parts, but when his company could not satisfy demand with die forged parts, Ford was forced to use stamping. Over the history of metal stamping, forging and deep drawing, presses of all types are the backbone of metals manufacturing. The processes continue to improve in moving more metal in one press stroke. Press and interconnected automation devices increase production rates, reduce labor costs and provide more safety for workers. Piercing and cutting can also be performed in stamping presses. Progressive stamping

1368-517: Was developed independently by Erma Werke 's Berthold Geipel with funding from the German Army . It took design elements from Heinrich Vollmer 's VPM 1930 and EMP . Vollmer then worked on Berthold Geipel's MP 36 and in 1938 submitted a prototype to answer a request from the Heereswaffenamt (Army Weapons Office) for a new submachine gun, which was adopted as MP 38. The MP 38 was a simplification of

1406-409: Was exacerbated by the presence of dirt or other debris. Another problem was that the magazine was also sometimes misused as a handhold. This could cause the weapon to malfunction when hand pressure on the magazine body caused the magazine lips to move out of the line of feed, since the magazine well did not keep the magazine firmly locked. German soldiers were trained to grasp either the handguard on

1444-572: Was only chambered in 9×19mm Parabellum . MP40 The MP 40 ( Maschinenpistole 40 ) is a submachine gun chambered for the 9×19mm Parabellum cartridge. It was developed in Nazi Germany and used extensively by the Axis powers during World War II . Designed in 1938 by Heinrich Vollmer with inspiration from its predecessor the MP 38, it was heavily used by infantrymen (particularly platoon and squad leaders), and by paratroopers , on
