Titanium Alloy Pistol Accessories Metal Injection Molding Parts

Look at the shape of the parts of the US MI7/18 pistol, there are circular marks on it, what is this? Many enthusiasts have consulted the editor on this question. For enthusiasts who don't understand the gun manufacturing industry, these details are really puzzling. Looking at the development of gun technology, material technology reduces the weight of guns and prolongs their life, detection technology ensures the quality of guns, chemical technology provides the power for guns to fire, and mechanical technology enables gun parts to be formed. Looking at the key technologies of the leapfrog development in the history of guns, almost all of them are the help of basic technologies. Thirty years ago, nylon materials were fully used in guns, and wood was no longer needed. Now, powder metallurgy is widely used in gun manufacturing. As for the hot additive manufacturing, it will take several years to fully roll out.

Today we are going to popularize the metal powder injection molding technology (Metal injection molding, MIM for short) that helps the rapid processing of firearms metal parts. This is a new production process that uses plastic forming technology and equipment conditions to form injection pellets made of a mixture of metal powder and binder in a mold cavity, and then degrease and sinter to become metal parts.

Application Of Mim Technology In Light Weapons

In 1973, MIM technology was invented in California, USA. Due to the infinitely bright technical prospects, industrially developed countries such as Europe, Japan and the United States invested a lot of energy in research. By the mid-1980s, it began to advance by leaps and bounds and successfully achieved industrialization. So far, it has become the most active component molding technology in the field of industrial manufacturing. However, in China, it started at least 10 years later than abroad. When searching for literature on the application of MIM technology in the field of light weapons, the earliest literature was an article published by Lin Jiubin of the 208th Institute in the third issue of Light Weapons in 1999, which briefly introduced the technology and made a feasibility analysis.

The revolver launcher parts formed by MIM, with circular injection marks on them, were officially tested and applied in 2000. Chongqing Changfeng Machinery Factory, Central South University, the 53rd Institute, Jinzhu Company and Yingjie Company jointly carried out technical research on the use of MIM technology to manufacture five complex-shaped parts of the Type 92 pistol. These five parts are the safety, hammer spring seat, barrel sleeve, rear sight, and trigger. There are two moving parts, and the rest are all static components. After the parts were prepared, comprehensive life tests, environmental tests, interchangeability tests, and safety tests were carried out at the national shooting range. The test results show that the parts manufactured using MIM technology can meet the national military standards. From then on, the prelude to the application of MIM technology to manufacture parts for Chinese light weapons was opened. From the actual application situation alone, the forming of parts is indeed convenient, but the surface treatment and detection are difficult, and further exploration of related auxiliary technologies is needed.

The Turning Point Of Mim Technology In The Comprehensive Application Of Weapons And Equipment

The initial trial of the Type 92 pistol in 2000 was successful, which can only be regarded as a pony crossing the river and understanding the depth of the river. The Type 03 automatic rifle is widely used in the field of light weapons in China.

This technology was unveiled in China in 2000 and applied to many types of firearms, but the performance was very frustrating. The mechanical properties were not stable. Some had a long life, while others had a short life. There were mixed fish and fish, and it was difficult to distinguish between good and bad. Quality problems were repeatedly exposed, and parts were repeatedly returned. Almost all application manufacturers had the phenomenon of scrapping and re-machining. There is no good technology in the world. Repeated tossing is inevitable. This is also a normal phenomenon in the application process of new technologies and new materials. It would be abnormal if it did not appear. Around 2010, MIM technology has been applied to at least 5 types of standard firearms. Today, most of the complex parts on light weapons are manufactured using MIM technology.

What is the current status? MIM parts still have great uncertainty. Experience tells us that parts that bear impact, moving components or parts with harsh working conditions should not be used as much as possible. In the development of the new generation of firearms, CNC processing and MIM technology have replaced the old forming methods, and a manufacturing pattern of "two parts and two places + machining" has been formed (two parts and two places + machining refers to: injection molding, metal powder injection molding, PIP/QPQ surface treatment, anodizing and machining) has been formed. The proportion of machining is getting smaller and smaller, leaving only aluminum alloys and key components.
