Technical Introduction

We produce automotive body parts by applying the hot stamping process.


The hot stamping process is a technology that uses electronic control technology to manufacture ultra-light and ultra-high strength parts by simultaneously molding and cooling in a mold after heating at a high temperature of 950 degrees or more. The increased strength of the product manufactured by the hot stamping process, will enhance safety and reduced the product weight and the vehicle weight as well.
