We specialize in manufacturing ultra-fine diameter core pins and micro precision shafts using advanced grinding technology.

This product utilizes powder high-speed steel (Powder HSS), offering excellent wear resistance, high hardness, and dimensional stability, making it ideal for precision die & mold applications requiring long tool life and consistent accuracy.

Our capabilities include producing long, micro-diameter components (sub-millimeter range) with advanced features such as tip SR (spherical radius) grinding and multi-step taper geometries, supporting high-mix, low-volume production.

We serve a wide range of industries including precision molds, medical devices, semiconductor equipment, and factory automation (FA).
