metal injection molding process

Provides high tensile strength and resistance against elongation and impact

High-density sintered body (relative strength over 95%) provides high tensile strength and resistance against elongation and impact.

High dimensional accuracy and superior surface smoothness
The dimensional accuracy is }0.5% or less. The surface roughness is 5S or less.

Suitable for mass production of products with complicated shapes
Metal injection can easily produce complicated shapes such as small thickness, sharp corners and deep holes. It is also suitable for mass production.

Up-to-date manufacturing facilities and strict quality assurance
Up-to-date manufacturing facilities controlled in a centralized manner and strict quality assurance ensure a stable supply of products.
