The hot pressed formwork stroke 180 degrees, within the inner place the180 degrees arc, the molding point can be set with formwork temperature below 280Centigrades. And also, time and location of the preheating can be shifted. The pressure of formwork is shifted.

Hence it may be applied to different allowance material, including the heat-crooked fireproof plank, the melamine ret blanket paper, plastic material slices, the plastic material membranes. May also be applied to sealing work piece of various shapes.
