Key technologies

Patch Work

일체복합성형

Patch-work production technology This production technology is to form multiple blanks simultaneously in one tooling after placing and tack-welding each individual blank on the main blank accurately.

Hot blow forming (HBF)

핫블로포밍 (HBF)

Hot blow forming production technology This hot forming technology is to obtain a desired shape by exerting high pressure inert gas to the inside of a pipe momentarily after inserting a pipe of high temperature into a tooling.

Friction stir welding technology (FSW)

 마찰교반용접기술 (FSW)

Hot blow forming production technology This technology is to bold two materials at a temperature lower than the melting point by using the frictional heat generated in the base metal after rotating the non-consumable tool of a special shape and inserting it in the base metal.

Plated steel sheet welding technology

 도금강판용접기술

Zinc plated steel based hybrid heating source welding technique This blow hole-free welding technique is to prevent blow hole, which may be generated by zinc vapor when welding zinc plated steel sheet that is the main material of auto body parts.
