1.What is the molding process?
The molding process of boots is a common production technology that combines the sole and upper, mainly by heating and pressing the sole material (such as rubber, PU, PVC, etc.) directly vulcanized or bonded to the upper through a mold.
2.Basic process flow

Mold preheating: The metal mold is preheated to the required vulcanization or melting temperature of the material (usually around 150-160 ° C for rubber).
Insert sole material: Place raw rubber sheets, PU prepolymers, etc. at the bottom of the mold.
Compression molding: Align the shoe upper with the mold, close the mold under high pressure, and form the sole material in hot pressing while firmly bonding with the shoe upper.
Cooling and shaping: Cooling after demolding to complete solidification or vulcanization.
Advantage:
No need for additional adhesive, environmentally friendly and durable.
The pattern on the sole can be finely designed through molds (such as anti slip patterns).
Disadvantages:
The cost of customizing molds is high, and small batches are not economical.
High temperature and high pressure may limit certain surface materials (such as heat-resistant fabrics).
