Check the mold to see if the mold wear is relatively large, the accuracy is not high enough, resulting in the production of silicone sleeve burr more, difficult to deal with the problem.
Curing temperature is too high or curing time is too long. Once the temperature of silicone products is too high, it will lead to numbness or brittleness after forming, which has a great impact on the subsequent edging. Long curing time is also one of the main reasons for brittle products.
Vulcanization temperature is too low or vulcanization time is too short, vulcanization temperature is too low, vulcanization time is too short will also have a certain impact on the edge, silicone rubber products have a strong flexibility when not completely vulcanized, so it is difficult to remove the rough edge and product separate.
From the production to solve these fundamental problems, we believe that the problem of silicone rubber products with rough edges can be well solved.
