1. The quality of the silicone raw material will make it difficult to remove the edge of the silicone product. The poor quality of the silicone raw material has insufficient toughness and obviously insufficient tear strength. It must be difficult to remove the edge during the process of removing the edge.
2. In the forming process, the product is relatively thick, so the burr is actually relatively thick, and the increase in thickness will definitely lead to the difficulty of removing the edge.
Third, the vulcanization environment factors, the vulcanization temperature should be appropriate, too high or too low will lead to difficult to remove the edge, and the vulcanization time also needs to be well controlled, the vulcanization time is too long, the product will become brittle, and the vulcanization time is too short. It will cause the vulcanization link to be ineffective, so the vulcanization link must be well controlled.
Fourth, the problems of forming molds, if the self-disassembly design of the mold is unreasonable, the forming mold is used for too long, the forming mold is severely worn, and the quality of the forming mold is not up to standard, it will be difficult to remove the edge after production and molding.
