Hot Stamping Dies for Body Structural Parts

Hot Stamping Die for Boron Steel Components

Hebei Haoxinran Machinery specializes in hot stamping dies for press hardening of boron steel automotive structural parts. Our hot stamping technology produces ultra-high strength steel components that reduce vehicle weight while improving crash performance.

Hot Stamping Process

• Material Heating: Boron steel blanks heated to austenitization temperature in furnace.

• Forming & Quenching: Parts formed and simultaneously quenched in the cooled die.

• Martensitic Transformation: Rapid cooling creates martensitic microstructure with ultra-high strength.

• Dimensional Stability: In-die quenching minimizes springback for excellent dimensional accuracy.

Typical Hot Stamped Parts

Our hot stamping dies produce A-pillars, B-pillars, roof rails, floor reinforcements, bumper beams, and door intrusion beams for modern lightweight vehicle bodies.

Haoxinran delivers complete hot stamping die solutions with process validation and tryout support.
