Molding Vulcanizing press machine operation introduction:

The setting of the vulcanization temperature and vulcanization time of the hot rubber molding vulcanizer needs to consider multiple factors. The following is a detailed introduction for you:

1. Setting the vulcanization temperature

1. Material properties

- Different rubber materials have different vulcanization temperature requirements. Generally speaking, the vulcanization temperature of natural rubber is around 140℃ - 150℃; the vulcanization temperature of synthetic rubber such as styrene-butadiene rubber, butadiene rubber, etc. may be slightly higher, between 150℃ - 170℃.

- For some special rubber materials, such as fluororubber, silicone rubber, etc., the vulcanization temperature may be higher or lower, which needs to be determined according to the characteristics of the specific material.

2. Product thickness

- The thicker the product, the higher the required vulcanization temperature. This is because it takes longer for heat to penetrate the thick product to ensure that the inside can also be fully vulcanized.

- For example, the vulcanization temperature of a thin rubber sheet may achieve a good vulcanization effect at a lower temperature, while a thicker rubber product requires a higher vulcanization temperature.
3. Type of vulcanizer

- Different types of hot vulcanizers may have different heating methods and temperature distribution characteristics, which will also affect the setting of the vulcanization temperature.

- For example, the temperature settings of a flat vulcanizer and a drum vulcanizer may be different. When setting the vulcanization temperature, you need to refer to the instruction manual of the equipment and adjust it according to the actual situation.

2. Setting the vulcanization time

1. Material properties

- The vulcanization speed of rubber materials is different, and the required vulcanization time will also be different. Generally speaking, the vulcanization time of natural rubber is relatively short, while the vulcanization time of synthetic rubber may be slightly longer.

- In addition, the vulcanization speed of rubber materials containing accelerators will be accelerated, and the vulcanization time can be shortened accordingly.
2. Product thickness

- The thicker the product, the longer the vulcanization time. This is because it takes longer for the heat to be transferred to the inside of the product so that the rubber inside can be fully vulcanized.

- Under normal circumstances, the vulcanization time can be increased according to a certain proportion according to the thickness of the product.
3. Vulcanization temperature

- The higher the vulcanization temperature, the shorter the vulcanization time. This is because at higher temperatures, the activity of rubber molecules is enhanced and the vulcanization reaction speed is accelerated.
- However, too high a vulcanization temperature may cause aging of the rubber material and degradation of its performance. Therefore, it is necessary to reasonably set the vulcanization temperature and vulcanization time while ensuring the vulcanization effect.
4. Equipment performance
- Different hot vulcanizers have different heating efficiencies and temperature control accuracy, which will also affect the setting of the vulcanization time.
- If the equipment has high heating efficiency and good temperature control accuracy, the vulcanization time can be appropriately shortened; otherwise, the vulcanization time needs to be extended.

When actually setting the vulcanization temperature and vulcanization time of the hot vulcanizer, it is recommended to conduct a small batch test first, and adjust the parameters according to the test results to determine the optimal vulcanization temperature and vulcanization time. At the same time, attention should also be paid to the safe operation of the equipment to avoid safety accidents caused by excessive temperature or excessive time.
