Silicone products can be caused by a variety of factors.
First of all, the issue of raw materials is an important factor. In the rubber mixing process, too high peroxide addition may cause the surface of the silica gel product to vulcanize rapidly, while the inside is not completely vulcanized. This will lead to the explosion of edges at the clamping line due to thermal expansion and contraction of the product during mold ejection. Therefore, reducing the amount of peroxide added and making the internal and external vulcanization of silicone products are the key to solving this problem.
Secondly, hardness issues can also lead to fried edges. Silicone products with low hardness are more likely to have **edges during the production process. This may be related to the configuration of parameters such as machine temperature and secondary exhaust. Therefore, it is an important measure to reduce the phenomenon of frying edge by establishing reasonable mechanical parameters, controlling the vulcanization temperature and time, ensuring that the raw materials are formed and processed in the curing stage, and avoiding the expansion of raw materials caused by too long time.
In general, in order to solve the problem of frying edge of silicone products, it is necessary to start from many aspects such as raw materials, hardness, machine parameters, etc., and comprehensively consider and take corresponding measures to reduce or avoid the occurrence of frying edges.
