Metal Injection Molding Secondary Operations

After a complex metal part is created through metal injection molding (MIM), sintered parts often require additional processing to achieve their final desired properties and specifications. 

Secondary operations can operate as critical steps in executing the full potential of MIM, rather than just optional finishing touches. They guarantee that parts not only fulfill the required shape and size but also offer the necessary mechanical, functional, and aesthetic qualities for seamless integration into their designated applications.

Cost Benefits of Secondary Operations

There are several cost benefits associated with secondary operations. Analyzing your specific situation is essential to understand how these operations play a role in the overall cost framework. Cost benefits of secondary operations include:


Efficient Production Processes

Secondary operations, like heat treatment, can improve the strength and dimensional accuracy of MIM parts. This could potentially lessen the need for scrap due to rejections caused by dimensional inconsistencies or insufficient strength.

Streamlined Assembly

Based on the design, certain secondary operations, such as threading or surface finishing, can eliminate the necessity for intricate post-assembly processes, resulting in time and labor cost savings. 

Increased Part Life

The application of heat treatment and surface treatments has the potential to enhance the wear resistance and durability of MIM parts. This could potentially lessen the requirement for frequent replacements and the associated maintenance costs. 

Decreased Material Waste

While MIM inherently reduces material waste compared to traditional machining, certain secondary operations, such as coining, can further diminish waste by eliminating the necessity for machining excess material.
