In the production process of silicone buttons, especially when producing thinner buttons, sometimes it is particularly easy to break during the next process of removing the edges. So, what is the reason for this situation?
1. The temperature during molding is too high. Silicone buttons become brittle when the temperature is too high during molding, and are prone to cracking and defects after demolding.
2. The operation method during demolding is incorrect. When demolding, many mold makers have not received professional training or are not careful in their work. They do not follow strict operation instructions to demold, which can lead to the breakage of silicone buttons.
3. Incomplete vulcanization of silicone buttons. When the temperature of the silicone button molding mold is too low or the vulcanization time is too short, it will cause the product to adhere tightly to the mold and be difficult to demold.
4. The silicone material used is too poor. Some factories blindly reduce costs and use inferior silicone button raw materials, resulting in poor quality silicone buttons, poor rubber material, poor toughness, and memory rupture.
5. Poor release of silicone buttons during mold lifting can cause the product to break during the lifting process.
6. Mold cavities with rough surfaces or accumulated dirt are not conducive to demolding, and molds that are difficult to demold are prone to breakage.
