1. The quality of the silica gel raw material is not good, the performance is too poor, and the toughness is not good, then it will easily cause rupture, so the silica gel raw material must be well controlled;

2. Silicone products are incomplete in the vulcanization process. When the molding mold temperature is too low or the vulcanization time is too short, it will cause the product to be close to the mold and not easy to be demolded, so it is easier to crack, and may also occur. In other cases, it is necessary to increase the molding temperature or lengthen the vulcanization time in the vulcanization process;

3. The temperature of the silicone product is too high during molding. If the temperature is too high, the silicone product will become brittle during molding, and it is easy to break when demoulding, and it is prone to breakage. Therefore, the molding temperature can be appropriately reduced;

Fourth, the surface of the silicone product forming mold is too rough or accumulates dirt, then it is very unfavorable for demolding, and it will also cause cracks. It only needs to clear the mold or electroplating!

5. Sometimes, because the operator's operation method for demoulding is irregular, many problems will easily occur, so the demolding operator needs to have professional operation training! It is inevitable for silicone products to break, but we can reduce the proportion of defective products caused by rupture through our good specifications. Generally, silicone rubber products account for the majority of broken silicone products, so it must be necessary in the production process. Pay attention to these aspects.
