The machine applies to vulcanizing various kinds of model rubber and plastic products as well as non-model products.

The machine is frame structure with downward pressing form (upward). Under the effect of working fluid pressure, the piston rises to make hot plate close for getting pressure, while the piston descends (namely hot plate turning on) by deadweight of hot plate itself, flat-bed and piston, which drive working fluid to fuel reserve tanks to achieve the aim of descending (namely turning on).
