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

Our strength lies in producing long, micro-diameter metal pins (under Ø1.0 mm) with high accuracy, including through-hole processing, tip radius (SR) finishing, and multi-step taper geometries.

We support high-mix, low-volume production and custom specifications for demanding industries such as medical devices, semiconductor equipment, precision molds, and factory automation (FA).

Our components are widely used as medical mandrels, core pins, guide pins, micro shafts, and precision tooling parts, contributing to miniaturization and high-performance applications.
