Temperature is a crucial factor influencing rubber products, and precise temperature control ensures optimal product quality when using vulcanization machines.
Based on different heating methods, the temperature rise in vulcanization machines (rubber molding machines) is primarily divided into the following types:
- Electrical heating.
- Oil heating and steam-fueled heating; among these, electrical heating is predominant.
This article mainly discusses electrically heated machines and temperature control.
After the electric heating system achieves a stable temperature, the required temperature across the entire heating plate should be maintained within ±3℃.
The entire machine’s heating time should not exceed 1 hour.
Typically, temperature control is divided into zones with segmented heating wires, and the temperature is managed by a thermostat.
If the temperature is too high, the product may cure too quickly; if too low, the product may not cure completely.
For temperature accuracy, the reading from the thermometer on the machine should be considered the standard.
