Metal Injection Molding | What Is MIM? | Benefits of MIM

2024-07-01

MIM, or metal injection molding, is a manufacturing process that combines the versatility of plastic injection molding with the strength and durability of metal materials. It is an ideal method for producing complex, high-precision components that are ready to install without the need for secondary operations.

One of the key advantages of MIM is its cost-effectiveness, particularly for medium to large production runs. By using fine metal powders mixed with a binder material, MIM can achieve near-net shape parts with tight tolerances, reducing the need for machining and finishing processes. This results in lower production costs compared to traditional manufacturing methods.

MIM technology is suitable for components with a high degree of shape complexity that are to be produced without reworking (undercuts, threads). The main areas of application are automotive and mechanical engineering, measurement and control technology, precision mechanics, the lock and fittings industry, tool technology, medical technology and the field of household appliances.

One of the main advantages of this manufacturing method is that components of high mold complexity can be produced in one piece eliminating the assembly of several parts of traditional processing techniques.

MIM technology is ideal for producing components of high mold complexity, such as undercuts and threads, without any subsequent machining required. Furthermore, it is possible to use materials not easily mechanically processed, for instance carbide metal, high-speed steel.

The manufacturing of components with geometrical detail that could not be mechanically produced is made possible by using MIM technology, e.g. lamellae with a wall thickness of less than 0.5 mm.

The MIM process is suitable for a wide range of materials, including stainless steel, superalloy, magnetic materials, tungsten alloy, titanium alloy, low alloy steel, tool steel, nickel-based alloy, cemented carbide, KOVAR alloy, fine ceramics, etc
