Why are silicone products not easy to dismantle?pacifier for baby Manufacturing

　　1. Quality problems of rubber materials

　　When the silicone product is formed from the mold, it first needs to do self-inspection. In the process of self-inspection, some products are easy to be dismantled, or the burrs cannot be removed. One of the reasons is the problem of the rubber material. In order to save costs, some silicone products factories often use some low-cost silica gel as raw materials. Such silica raw materials can be used for some low-demand silicone products, but they have high requirements for burrs and are not easy to disassemble themselves. product is very difficult. If it is used on some silicone products with more complex structures, such as silicone miscellaneous parts, it requires relatively high silicone miscellaneous parts.

　　2. The vulcanization temperature is too high or the vulcanization time is too long

　　The vulcanization time involved in the molding process of silicone products is also related to the quality of the product. If the molding time of the product is relatively high, the temperature will be too high, which will cause the product to become numb or brittle during the molding process. If the vulcanization time is too short, the molded product will not be dismantled.

　　3. The vulcanization temperature is too low or the vulcanization time is too short

　　If the curing temperature is too low or the curing time is too short, it will also have a certain effect on the edge removal. Silicone rubber products are very flexible when not fully vulcanized, so it is not easy to separate the burrs from the product when removing the edges.

　　Fourth, the molding thickness is too thick

　　This is the simplest and easiest to understand. I don't need to explain too much, as long as the molding is as thin as possible while ensuring that the size is qualified.

　　Why is it difficult to remove the edges of silicone products after molding?

　　Five, mold reasons

　　The self-disassembly design of the mold is unreasonable or the production quality is not high enough, or the mold has been used for too long and is worn out, which makes it difficult to disassemble the edge. The mold designer does not divide the mold reasonably when designing the mold, and the self-disassembly opening is not sharp when making the mold, which will cause the product to be difficult to disassemble after molding. side.

　　6. Other factors

　　The wear of the mold in the production process or the excessive number of sandblasting will also cause the self-disassembly roughness and affect the self-disassembly performance of the silicone rubber product after molding.

　　About silicone products

　　The production of silicone rubber products is a complex process, and the quality is not only good or bad except for machine and human factors. Intermediate inspections are the key to finding and resolving major product quality issues. Therefore, maintaining the normal operation of the machine, the good working condition of the mold, and strengthening the operation skills and quality awareness training of operators and quality control personnel are the key to reducing production defects and the benefit of the enterprise.
