Hot stamping technology

This image is modified because it contains confidential matter.

Hot stamping is the process of hardening materials by press-molding a steel plate heated to a high temperature and cooling it quickly in a mold to create products with high-strength. To manufacture a lightweight and highly rigid body, hot stamping is a crucial technique together with the utilization of super high-tension materials. In the past, hot stamping used to be a high-cost technique considered unsuitable for mass production due to its low processing speed and the difficulty in welding the hardened product.However, through the simultaneous processing of four components, it has become possible to process materials at twice the speed of conventional techniques. In addition, through the water cooling mold technique which controls the water temperature, water flowing position, and flow rate during press molding, molding can be completed only in several seconds, thus significantly increasing productivity.

Tailored Blank Welding Technology

Our tailored blank welding system, which uses mash seam welding equipment and YAG laser welding equipment developed in-house, fuse thick steel plates for sections requiring high strengths with thin steel plates in other areas before auto body component press processing is performed, creating highly rigid yet low weight auto body components. This contributes greatly to reduced auto body weight.

High-Tensile Strength Steel Sheet Material Processing Technology

High-tensile strength materials can offer high strengths with thin plates, so hopes are high for thei r effect iveness in automobi le weight reductions. The higher the tensile strength of a material, the more difficult it is to perform press work on, but we are using simulation technologies to research and develop optimal processing methods and are working toward their practical application.
