3DQ, Three-Dimensional Hot Bending Quench
3DQ technology is the continual process of steel tubes with diverse shapes (round, square, and various different shapes) to be heated and sequentially quenched with cooling water as they pass through the manufacturing line. By using this technology, high-tensile strength steel tubes with complex bended shapes can be manufactured without using dies.

Direct-Water-Cooling HOT PRESS Forming
The existing HOT PRESS forming seeks an indirect cooling of steel sheet steel, by the flow of cooling water through the inside of the dies. Whereas, the new Direct-Water-Cooling HOT PRESS forming, put to practice this time, in addition to ordinary cooling way ejects from the die surfaces the cooling water, which, flowing through the space between the die-surface and the steel sheet panel, cools the steel directly. Direct-Water-Cooling means productivity improvement about three times that of the existing indirect one.
