Hot Stamping

Magna has taken an industry lead in bringing the hot stamping forming process to body structure applications, especially in areas where vehicle crash performance must meet ever-increasing government regulations. Hot stamping allows for the forming of complex part geometries, traditionally achieved only through the cold forming of mild steels. With hot stamping, the final part achieves ultra-high strength material properties. Applications of this process include body pillars, rockers, roof rails, bumpers and door intrusion beams. The hot stamping process at Magna has the ability to produce tailored mechanical properties by quenching the hot formed part at various rates. These tailored tempered properties in defined areas of hot stamped parts guarantee material properties that can withstand high strain during a crash event for energy absorption, while the non-tailored areas offer high strength needed to prevent intrusion. This enables the vehicle body in white to be lighter and safer with the usage of tailored temper properties.
