Working Principle of Vulcanization Equipment
Vulcanization equipment uses heat, pressure, and time to crosslink rubber molecules through vulcanizing agents (sulfur or peroxides), giving belts strength, elasticity, and heat resistance.
- Heating
Steam, hot air, electricity, or heat-transfer oil raises the mold or drum to 150–180°
- Pressurizing
The belt blank is pressed in the mold or on the drum to bond layers tightly and maintain the designed shape.
- Crosslinking
Heat and pressure cause rubber molecules to form crosslinks, improving mechanical properties.
- Shaping
The mold or drum ensures dimensional and profile stability (especially for toothed belts).
- Cooling & Demolding
After vulcanization, the belt is cooled to retain shape, then removed or cut.
Production Equipment Processing Details
Vulcanization equipment crosslinks and shapes the rubber under controlled heat and pressure, producing belts with final mechanical performance and stable geometry.
