LSR (Liquid Silicone Rubber) injection mold is a key equipment for liquid silicone product production, and its design and processing level directly affects the quality and production efficiency of products. TYM, as a professional manufacturer of LSR injection molds, has rich experience in mold design and processing, and summarizes the key points of LSR injection mold design and processing, helping enterprises improve the quality of molds and products.
The key point of LSR injection mold design is to ensure the fluidity and uniformity of the silicone material. LSR has the characteristics of low viscosity and fast curing, so the mold runner design is very important. TYM’s mold designers adopt a reasonable runner structure, ensuring that the silicone material can flow smoothly in the runner, avoiding dead corners and stagnation, and ensuring the uniformity of the material filling. At the same time, the mold gate design is also crucial, and the size and position of the gate are determined according to the product structure and size, ensuring that the material can be filled quickly and evenly, and avoiding product defects such as burrs and shrinkage.
Another key point of LSR injection mold design is temperature control. LSR requires a certain temperature to cure, so the mold needs to be equipped with a reasonable temperature control system. TYM’s LSR injection molds adopt a multi-zone independent temperature control design, which can accurately control the temperature of each part of the mold, ensuring that the silicone material is fully cured, and improving the strength and elasticity of the product. At the same time, the mold cooling system is also optimized, which can quickly cool the product after molding, shorten the production cycle, and improve production efficiency.
In terms of mold processing, the key point is to ensure the precision and surface quality of the mold. TYM uses advanced processing equipment such as CNC machining centers, EDM and wire cutting machines, which can process the mold with high precision, ensuring that the mold size error is within ±0.005mm. At the same time, the mold surface is polished and treated to ensure that the surface is smooth and free of burrs, avoiding affecting the surface quality of the product. In addition, TYM strictly inspects each link of mold processing, ensuring that the mold quality meets the requirements, and providing reliable guarantees for the production of high-quality LSR products.
