KATAGIRI's original cold forging technology & die design.

確かな技術と自由な発想 新しいライフスタイルをご提案します

Katagiri Co., Ltd. introduced cold forging technology for the first time in 1966 in Tohoku. Since then, as a pioneer of precision cold forging, we have established advanced mass production technology that achieves both stable quality and high productivity through repeated research and development.
At present, we have realized the production of products with high cost performance through an advanced production system that pursues automation and labor saving from process analysis to pre-processing processes, mold design / production, molding processing, and secondary processing. Furthermore, we have developed the world's first technology with small diameter precision cold forging and made it possible to manufacture more precise parts.
Also, in-house development of super abrasive tools due to the necessity of precision mold machining.
In addition to manufacturing and selling the “STRAX” brand throughout the country, we also manufacture and sell carbide materials that have been successfully developed to improve mold life and various molds that use them.
