Stamping and roll forming high-strength steels
Advanced and ultra-high-strength steels and press-hardening steels: what changes in die design, simulation and roll forming when parts get stronger.
Why strength keeps rising
Lighter bodies, better crash performance and heavier electric vehicles push car makers toward advanced high-strength steels (AHSS), ultra-high-strength steels (UHSS) and press-hardening steels.
Cold stamping AHSS
Higher strength means more springback, higher forming forces and more wear. Dies need springback compensation in the die face, stiffer structures, higher-grade inserts and suitable coatings. Simulation with accurate material data is essential.
Hot stamping
For the strongest safety parts, press hardening forms the blank hot and quenches it in the die, up to 2,000 MPa. The die then includes cooling channels and is designed with thermal simulation.
Roll forming
Roll forming forms the material progressively, pass after pass, which suits very high-strength steels for long profiles such as beams and reinforcements.
Choosing the process
The right process depends on the part shape, the grade and the volumes. Contact us with your part and material for a feasibility study.
