How does an ordinary rubber conveyor belt vulcanization press work?
An ordinary rubber conveyor belt vulcanization press works by initiating a chemical reaction called cross-linking within the rubber layers. By maintaining a steady temperature of approximately 145°C under high pressure, the press forces the sulfur molecules to form bridges between the polymer chains. This results in a splice that is much stronger than cold-welded alternatives.
The science behind the bond
When you operate an ordinary rubber conveyor belt vulcanization press, you are effectively “cooking” the belt joint. This process ensures the new rubber and the original belt carcass become a single, inseparable unit.
- Molecular bridge formation (cross-linking).
- Chemical activation of bonding agents.
- Thermal stabilization of the rubber compound.
- Elimination of internal structural offsets.
But that is only the beginning:
Importance of the pressure cycle
Pressure is applied to ensure that the liquefied rubber flows into every fiber and around every steel cable. The ordinary rubber conveyor belt vulcanization press uses either mechanical bolts or a fluid-filled pressure bag to exert even force across the entire surface area.
- Forced air removal from the splice.
- Perfect encapsulation of reinforcements.
- Compression of the rubber to prevent porosity.
- Uniform density throughout the joint area.
Here is the interesting part:
Key TakeawayThe synchronization of heat and pressure ensures that the physical properties of the joint match the rest of the conveyor belt.
| Variable | Requirement | Impact on Joint | |
|---|---|---|---|
| Temperature | 145°C (±5°C) | Triggers chemical cure | |
| Pressure | 100 – 200 PSI | Eliminates internal air | |
| Time | 30 – 60 Minutes | Ensures full cross-linking |
High-performance vulcanizing depends on managing these variables with absolute precision to avoid under-curing or burning the material.

Frequently Asked Questions
Can I use a vulcanizing press on a belt that has already been cold-bonded?Concise Judgment: Yes, you can. You must completely remove the old cold-bonding adhesive by mechanical buffing until you reach clean rubber. Any residual cold-cement will prevent the new hot-vulcanizing compound from forming a chemical bond during the press cycle.
What’s the best way to determine the correct cure time?Concise Judgment: Refer to the belt’s technical data sheet. A general rule of thumb is a base cure time of 20-30 minutes plus 2-3 additional minutes for every millimeter of belt thickness to ensure heat reaches the core fibers.
Can I perform vulcanization in the rain?Concise Judgment: No, it is not recommended without a shelter. Moisture trapped in the splice turns into steam under the high heat of the press, creating “bubbles” and voids that significantly weaken the joint’s structural integrity.
How do I know if the heating plates are heating evenly?Concise Judgment: Use a thermal imaging camera. Periodically checking the platens during a test run will reveal “cold spots” which usually indicate a failing heating element that needs replacement before your next repair.
Can I use air instead of water in my pressure bag?Concise Judgment: It depends on the bag model. Some bags are dual-rated, but water is generally preferred for high-pressure industrial applications because it is non-compressible and provides more stable force than air.
