What is Metal Injection Molding (MIM)?

A High-Precision Manufacturing Process for Small, Complex Metal Parts

What is MIM?

Metal injection molding (MIM) combines plastic injection molding and powder metallurgy to manufacture small, complex metal parts efficiently and in high volumes. The process enables greater design flexibility and allows multiple components to be integrated into a single precision part.

Inside the MIM Process

Metal injection molding turns metal powder and binders into moldable feedstock. Through injection, debinding, and sintering, it creates strong, complex parts with high precision. This process is ideal for efficient mass production.

Why Metal Injection Molding Works

MIM is ideal for creating compact, intricate parts at scale with excellent performance.

Fine detail and complex shapes
High part density
Flexible design options
Custom-made solutions
Stable quality in mass production
Integration of multiple parts
Fewer assembly steps

Broad material selection
Excellent mechanical properties
Shorter production cycles
High dimensional accuracy
Lower defect rates
Cost-effective for volume runs
