Metal Powder Injection Molding (MIM)

Metal Injection Molding

Boasting advanced MIM production lines, we realize complex-shaped metal components with ±0.008mm precision. Integrating powder mixing, injection molding, debinding and sintering, it handles intricate geometries hard for traditional machining. Adaptable to stainless steel, titanium alloy and other materials, it’s ideal for medical devices, aerospace parts and electronic components. Backed by custom design support and strict quality control, we deliver high-performance, cost-effective solutions for both prototypes and mass production.

MIM: The Right Choice for Intricate Parts

Use the following criteria to determine whether Metal Injection Molding is suitable for your component.

Ideal Part Characteristics	Small, intricate and repeatable components.
Complexity	Internal holes, threads and shapes that are costly to machine.
Production Fit	Best considered when production volume supports tooling investment.
Comparison Focus	Compare complexity, material waste, part size and volume economics.
