PR message
Mainly metal processing (stainless steel, aluminum, iron and other metals) with milling, machining and plate processing machines
We undertake precision cutting.
We've made numerous achievements with machining in general for machining equipment parts such as industrial machine parts, mold components, semiconductor equipment parts and jigs. In particular, we take rush orders for production at our machining center.
We are working to improve our operations day by day to answer customers' quality, cost and quick delivery needs.
We handle various kinds of material qualities including all types of iron, aluminum, stainless steel, casting and resins.
