Hot vulcanization splicing is the method that guarantees the highest joint strength in rubber conveyor belts — above 90% of the original belt strength. But conventional vulcanizers present three real problems:
- •Weight and logistics: The copper plates and traditional hydraulic systems make transporting and mounting the machine in the field a task in itself.
- •Natural cooling: Waiting for the joint to drop from 145 °C to below 70 °C takes around 2 hours. In high-production environments, that means direct downtime.
- •Lack of control: Without automatic temperature control, the result depends on the operator, not the process. No traceability, no alarms, no reproducibility.
The ComiX ALEX Ultra Light range solves all three. At NFP Industrial we represent Wuxi ComiX Vulcanization Technology Co., Ltd. in Europe and Latin America. ComiX is a specialized manufacturer with ISO 9001:2015 certification, operational headquarters in the USA and a registered trademark in Germany. Present in more than 60 countries.
