It makes use of the advanced technology of hot pressed forming to merge these processes, include rubberize, heating and solidification and so on, consistently. It is better than conventional heating furnace, which has several operation periods separately. Heating temperature and heating time can depend on workpiece property to reset them. Because of pneumatic fixed type, the workpiece has uniform surface pressure, and the gap between two rubberized materials can always keep uniform. Due to multi-mold cavity in one machine, it is able to produce continually and to raise productivity.
