Hot Forming Process

Abstract

In the direct hot forming process, a blank is heated up in a furnace, transferred to the press and subsequently formed and quenched in the closed mold [1] (Fig. 3.1). First the sheet is uncoiled and cut according to the shape of the product, then the blank is transferred to a continuous furnace, in which it is heated and fully austenitized. Thus the product is formed and quenched after the blank is transferred to the hot forming mold with cooling system. Afterwards the product is trimmed by laser and finished through other follow-up process.
