Hot Press Forming
Hot Forming method — ultra-high-strength body part manufacturing technology
Heating approx. 520MPa-class steel sheet to over 870℃,
then forming and rapid-cooling simultaneously into 1,780MPa-class
Hot Forming technology is a method that heats an approximately 520MPa-class steel sheet to a high temperature above 870℃, then forms it while rapidly cooling it within the die to manufacture ultra-high-strength parts of approximately 1,780MPa class. This method offers excellent formability and dimensional precision and can be realized with high strength and quality, contributing to vehicle body weight reduction and improved crash safety.
Hot Forming Process Line
Hot Press Forming
The core method that forms ultra-high-strength body parts with 800-ton and 1,200-ton presses.
Local Softening
Local-softening equipment that differentially controls strength by region optimizes crash-energy absorption performance.
Dew-Point Control
A dew-point controller manages the heating atmosphere to secure surface quality and coating adhesion.
Laser Trimming
TRUMPF laser equipment performs precision trimming and hole machining of ultra-high-strength formed parts.
