The Metal Injection Molding Process
Metal Injection Molding is a sophisticated technique that combines the benefits of plastic injection molding with the properties of metal powders. The process begins with the mixing of metal powders with a polymer binder, resulting in a feedstock that can be easily injected into molds.
Once the feedstock is prepared, it is heated and injected into a mold under high pressure. This step allows for intricate designs to be formed, accommodating various shapes and features needed in weapon components. After the injection phase, the molded parts undergo a debinding process to remove the polymer binder, leaving only the metal powder.
The pieces are then sintered in a furnace, where they are heated to a temperature below their melting point. During sintering, metal particles fuse together, achieving desired density and strength. This final step is crucial, as it solidifies the components, making them suitable for use in military applications.
The entire Metal Injection Molding process is divided into key stages:
- Feedstock preparation
- Injection molding
- Debinding
