Creative solutions made with MIM
Flexibility with Strength
Metal Injection Molding (MIM) combines the design flexibility of plastic injection molding with the strength and durability of metal materials. MIM is a cost-effective alternative to traditional metal manufacturing processes, making it a popular choice in industries such as aerospace, automotive, and medical devices.
Advantages of MIM
- Complex geometries
- Efficient use of material
- Less material waste as a result of producing near net shape components and considered a green technology
- Excellent mechanical properties
- Tailored solutions using unique materials formulated to meet component/application requirements
- Can be brazed/joined to a variety of components for complete assembly solutions

The MIM process uses a wide array of alloys and metals. From stainless steel to tungsten alloy to low alloy steel, and more, MPP provides expertise in working with any material used in the MIM process. MIM is an excellent alternative to other forming processes, including Inconel casting for aerospace manufacturing.
The most commonly used elements in MIM processing are:
Iron and nickel are two of the easiest elements to process because of their compatible melt temperature and ease of sintering. Iron and nickel make up a significant amount of the total tonnage produced in the industry.
