Hot Stamping

Overview
It is a processing method of manufacturing a 1.5GPa class ultra-high strength part by heating a 490~590 MPa class steel sheet to 970℃ or higher, forming it with a mold, and rapidly cooling it

- No need for additional reinforcement to improve strength (Light-weight)
- Reduction of the number of welds by removing parts (Improving productivity & Reducing investment)

Partial Quenching

Mold local heating

Material yield increase

 

 

 

Shortening the process

Cold trimming after forming
hot stamped products

 

Shortening cooling time because of
direct injection cooling channel
