Polyurethane Sole/Insole Molds

Of Rotary Sole/Insole Production Line

The mold uses pneumatic opening and closing to reduce labor and costs, and reduce waste caused by operation.
The mold uses circulating water heating, which saves more than two-thirds of energy consumption compared to traditional methods, and the mold temperature is controlled within ±2℃.
High-precision processing: CNC precision processing technology is used to ensure that the sole details are clear and the molding size is consistent.
Diversified design: Single-cavity or multi-cavity molds can be customized to suit different styles of sports shoes, casual shoes, safety shoes, etc.
Mold split structure: Convenient demoulding and cleaning, support semi-automatic or fully automatic demoulding equipment for use.

Robot Arm
