Press Hardening
Hot Stamping Forming
Hot stamping forms a heated steel blank while rapidly quenching it inside the die to secure strength. It resolves the conflicting demands of formability and strength in a single process, but in-die cooling-channel design determines quality. JISUNG applies the press-die design capability accumulated since 1988 directly to hot-stamping die structures.

01
Hot Stamping Die DesignHot Stamping Die
- Upper/lower die structures that withstand both high-temperature forming and quenching
- Material selection and split design considering thermal distortion and wear
02
Cooling Channel DesignCooling Channel
- Channel layouts that secure die-quenching cooling rates
- Reducing local cooling deviation to prevent hardness non-uniformity
03
Forming & Process ValidationForming Validation
- Predicting fracture, wrinkling and thinning in advance via forming analysis
- Geometry review assuming laser-trimming post-processes
Process
Hot Stamping Process
From heating to post-processing, temperature and time determine quality.
Step 1Blank HeatingHeating a boron-steel blank into the austenite range
Step 2TransferRapid transfer to the die while minimizing temperature drop
Step 3Forming & QuenchingDie quenching via in-die cooling channels during press forming
Step 4Laser TrimmingHigh-strength formed parts are cut and pierced by 3D laser
