What is MIM | MIM (Metal Injection Molding) Parts Manufacturing in Thailand

What is MIM (Metal Injection Molding)?

CASTEM's MIM technology has been independently researched and developed, and it's patented in the United States.
We can manufacture small products with complex shapes and thin walls that other companies cannot manufacture.

► Features of our MIM

Quantity	Small to large lots (dozens to tens of thousands of pieces)
Shape	Suitable for small products with difficult-to-cut shapes
Material	Mainly stainless steel, but also alloy steel and tool steel.
Appearance	Smooth finish below 3.2a
Strength	High strength with density over 95%.

MIM

Excellent mechanical strength because its density reaches over 95% and its vacancies are spherical and independent.

Conventional Sintering

The body made by standard sintering has poor mechanical strength properties because its density reaches only 88% and its vacancies exist along the grain boundary irregularly.

It indicates properties similar to that of molten material such as torsion and spring. (The products in the photo are made of SUS304)
