Metal Injection Molding FAQs

Metal injection molding is ideal for producing small, complex parts, while die casting is suitable for larger parts. The biggest difference between MIM and die casting lies in the raw materials.

MIM is the process of forming a final product by metal powder injection molding. Die casting is the process of filling a mold with molten metal to form a finished product.

Metal injection molding and plastic injection molding use different raw materials. The process of metal injection molding is more complicated and the cost is higher.

PM materials and MIM materials are produced by the same processes. However, PM requires smaller metal powders, about 50-100μm in size, while metal injection molding is 2-20μm.

Metal Injection Molding is widely used to produce small, complex, and high-strength parts. Common applications include components in medical devices, electronics, automotive systems, consumer products, and firearms.

It’s ideal for high-volume production of detailed parts that are difficult or costly to machine.

MIM parts typically achieve a standard tolerance of ±0.3% to ±0.5% of the nominal dimension. 

However, actual tolerances depend heavily on part geometry, and tighter requirements can be met through secondary machining.

Yes, MIM parts can be heat treated and plated just like conventional metal components.

They can undergo heat treatment to enhance hardness or strength, and plating processes such as nickel, chrome, or gold can be applied to improve corrosion resistance, conductivity, or appearance.
