1.The temperature is too high during molding: the silicone button will become brittle when the temperature is too high during molding, and it will be easily broken after molding, which will cause it to be broken, and it is only necessary to properly lower the molding temperature.
2.Silicone button vulcanization is not complete: When the temperature of the silicone button molding mold is too low or the vulcanization time is too short, it will form a product that is not close to the mold, so it is easy to form a break, and the mold temperature or the extended vulcanization moment is properly promoted. Can be processed.
3.The appearance of the silicone button molding die is too rough or the dust is accumulated: the cavity with rough surface or dust accumulation is not suitable for demoulding, and the mold which is not simply demoulded is very simple to break, and the mold needs to be cleaned or plated.
4.The operation method is not correct when demoulding: Many mold masters do not pass the professional training during the demoulding, or the operation is not careful. If the mold is not released according to the strict operation instructions, the silicone button will be broken. This requires professional operation for the operator. Operational skills training may lead to the development of strict operating guidelines.
5.When the mold is pressed, the silicone button is not well-formed: the product breaks during the die-cutting process. At this moment, it is necessary to spray a proper amount of the release agent on the surface of the silicone button mold to continue production.
6.used silica gel raw materials are too bad: some factories blindly reduce the cost of using the defective button silica gel raw materials, resulting in poor quality of the output silicone button, the rubber is too poor, the resistance is not good, the memory breaks, very normal. To handle this question, you need to replace the better button silicone.
