Metal Injection Molding (MIM) could produce the pretty small and complex metal accessories with high precision and difficult structure, and many material could be used on MIM process,such as stainless steel,iron base,ceramic material,titanium alloy,tungsten alloy and so on. Metal injection molding was used on military machinery production on early stage,including guns body, gun shells and so on. Because the gun accessories structures and shapes are very complex and the use environment is always dangerious, so all the guns accessories must have high quality,including the mechanical property,density and precison level.
Basically all the traditional guns accessories were made by forging process and secondary CNC machining process, although we could use CNC machining process to realize more precise gun accessories, the material utilization of machining material is low, especially the hand gun accessories and metal gun shells and so on, the machining material utilization rate is only 15%-20% approximately ,means most of the material has been cutted and wasted. Meanwhile, for the small and micro gun accessories,such as the gun trigger,if we use high strength material to do ,such as carbon steel, then it would be very very difficult and the efficiency would be pretty low,so it is not economic.
We could use Metal Injection Molding technology to produce many accessories with various complex structure, if so, we could solve the trouble that the low efficiency of machining cutting process , so we could save much material to reduce the production cost greatly. So with many unique superiorities,more and more manufacturers use it to produce various gun accessories,such as triggers,gun shells and so on. With the rapid development of Metal Injection Molding, MIM gun accessories covered a larger and larger percentage of guns products.
The accessories made by Metal Injection Molding has high density 7.8g/cm3 which is very close to steel and less CNC machining process to reach the required precision, thus Metal Injection Molding becomes more and more popular.
