One: Poor quality silicone raw materials, with poor performance and low toughness, are prone to cracking. Therefore, strict quality control is essential in the selection of silicone raw materials.

Silicone products may stick to the mold and be prone to cracking if the vulcanization process is incomplete, such as when the molding mold temperature is too low or the vulcanization time is too short. This can lead to other issues as well. Therefore, it is necessary to increase the molding temperature or extend the vulcanization time during the vulcanization process.

The molding temperature for silicone products is too high, which can make the products brittle during molding, prone to cracking during demolding, and thus more susceptible to breakage. Therefore, it is advisable to lower the molding temperature appropriately.

Four, if the surface of the silicone product mold is too rough or accumulates dirt, it is very不利于 demolding and can also cause cracking. Simply clear the mold or electroplate it!

Five, sometimes due to irregular demolding techniques by operators, many issues can arise, so professional operation training for demolding staff is necessary!

We cannot avoid the cracking of silicone products, but we can reduce the percentage of defective products caused by cracking through our strict regulations. Generally, most of the cracked silicone products are silicone rubber accessories, so attention must be paid to these aspects during the production process.
