AI Technical Summary
Existing hot pressing equipment uses resistance heating, which consumes a lot of energy and loses a lot of heat. The exposed hot pressing area further increases energy consumption.
The thermal oil heater in the oil tank is used to replace the resistance heating. Combined with the heat insulation rubber sleeve and the movable heat insulation sleeve, the hot pressing area is sealed. The lower mold is driven to rise and fall by the lifting mechanism to achieve heat insulation and sealing.
It reduces heat loss, lowers energy consumption, improves heating efficiency, and facilitates dust cleaning.
