Why is it difficult to remove the edge of silicone products?

After the molding and printing of silicone rubber products, it is necessary to tear the burr and repair the burr to be a complete finished product, but many operators often encounter a situation, that is, some silicone rubber products are very difficult to remove the edge, and the slight carelessness will break or leave the burr, which will lead to extremely slow work efficiency and increase the defect rate. What factors lead to the difficulty of removing the edge of silicone rubber products.

1、 The quality of silicone rubber raw materials will make it difficult to remove the edges of silicone rubber products. The toughness and tear strength of silicone rubber raw materials with poor quality are obviously insufficient. It must be difficult to remove the edges in the process of edge removal.

2、 In the forming process, if the product is formed thicker, the burr is actually thicker, and the increase of thickness will certainly lead to the difficulty of edge removal.

3、 The vulcanization environmental factors and vulcanization temperature should be appropriate. The problems of too high and too low will lead to difficult edge removal. At the same time, the vulcanization time also needs to be well controlled. Too long vulcanization time will lead to brittle products, and too short vulcanization time will lead to ineffective vulcanization links, so the vulcanization links must be well controlled.

4、 For the problems of forming molds, if the self disassembly design of molds is unreasonable, the use of forming molds is too long, the wear of forming molds is serious, and the quality of forming molds is not up to standard, these conditions will lead to difficult edge removal after production and forming.

For the silicone rubber product factory, it is often difficult to remove the edges of silicone rubber products, which is also a detail that needs the attention of silicone rubber product manufacturers. Only by doing the details well can the silicone rubber product manufacturers move forward steadily and orderly!
