The production process of silicone keys is much more complicated compared to some other silicone products. Therefore, the defective rate of silicone keypads has been a special concern for silicone product manufacturers. To reduce the defective rate of silicone keys and improve the quality of products has been one of the purposes of Cushion, the following Cushion Electronics has sorted out some of the reasons affecting the defective rate of silicone keys.

A. The temperature is too high when molding

       Silicone keys in the molding temperature is too high will become brittle, molding after demolding, it is easy to break bad, just need to properly reduce the molding temperature can be.

Second, silicone keys vulcanization is not complete

       When the silicone button molding mold temperature is too low or vulcanization time is too short, it will cause the product clinging to the mold is not easy to release, so it is easy to cause rupture, appropriate to increase the mold temperature or extend the vulcanization time can be solved.

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

       Surface roughness or accumulation of dirt mold cavity is not conducive to demoulding, and not easy to demould the mold is easy to rupture, the mold needs to be cleaned or plating treatment.

Fourth, the operation method is not correct when demoulding

       Demoulding many mold masters are not professionally trained or work inattentively, not in accordance with strict operating instructions when demoulding, will lead to bad rupture of silicone keys, this requires professional training in operating skills or the development of a strict operating system for operators.

Five, lift the mold when the silicone keys from the degree of bad

       resulting in the rupture of the product in the process of lifting the mold, then the surface of the silicone button mold needs to spray the appropriate amount of release agent to continue production.

Sixth, poor silicone raw materials

       Some factories blindly reduce costs by using poor quality silicone raw materials, resulting in the production of silicone keys of poor quality, the rubber is too poor, bad toughness, memory rupture, very normal. To solve this problem will need to replace the better key silicone.
