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

This product utilizes nitrided powder high-speed steel, offering exceptional wear resistance, surface hardness, and extended tool life, making it ideal for medical device mold applications and high-load precision tooling.

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 medical devices, precision molds, semiconductor equipment, and factory automation (FA).
