Precautions for the quality requirements of silicone keys in the production process

　　I. Molding temperature is too high

　　The silicone button will become brittle when the temperature is too high during molding, and it is easy to release after molding, and the cracks are poor, so that the molding temperature can be properly reduced.

　　2. Silicone peony vulcanization is not complete

　　If the temperature of the silicone button molding mold is too low or the vulcanization time is too short, the product is in close contact with the mold, it is difficult to release the mold, and it is easy to break, so it can be solved by appropriately increasing the mold temperature or extending the vulcanization time.

　　Third, the surface of the silicone button molding mold is too rough or dirt

　　The cavity with rough surface and dirt accumulation is not conducive to demoulding, and the mold that is not easy to demoulding is easy to break, so it is necessary to clean or electroplate the mold;

　　Four. The operation method of demoulding is wrong

　　Many mold workers do not have professional training when demoulding, or do not work carefully, do not follow the strict work instructions, may lead to silicon button damage. This requires professional operational skills training for staff or the development of strict work systems.

　　Five. When demoulding, the silicon button demoulding degree is not good

　　When the product breaks during the comparison process, it is necessary to spray an appropriate amount of release agent on the surface of the silicone key in order to continue production

　　Six. The button silicon used is not good

　　Some factories use poor quality peony silicon raw materials at will to reduce costs, and the peony produced is of poor quality, poor rubber material, poor toughness, and broken memory, which is very normal. To solve this problem, it is necessary to replace a good key silicone.

　　In the molding process, special attention should also be paid to prevent the silicon button from breaking, mainly from what aspects:

　　1. Silicon button vulcanization is not complete: the temperature of the silicone button molding mold is too low or the vulcanization time is too short, and the product is difficult to release in close contact with the mold, so it is easy to break. It can be solved by moderately increasing the mold temperature or extending the vulcanization time.

　　2. The surface of the silicone button molding mold is too rough or dirty. The cavity with too rough surface and dirt accumulation is not conducive to demoulding, but the mold that is difficult to demoulding is easy to break, and requires mold cleaning and electroplating treatment.

　　3 molding temperature is too high: silicone products molding temperature is too high easy to become brittle, molding after stripping, cracks appear bad, just reduce the molding temperature appropriately.

　　4. Poor model of the comparative silicone button: the product breaks during the comparative process, and the silicon button surface needs to spray an appropriate amount of release agent to continue production.

　　5: The operation method is wrong when demoulding: when demoulding, many mold workers do not have professional training or do not work seriously, and do not release according to strict operation instructions, which will cause damage to the silicon button. This requires professional operational skills training for staff or the development of strict work systems.
