Liquid silicone molding is a relatively common injection molding process for silicone product manufacturers at present. The difference between it and solid silicone products is that many products can be produced and molded more efficiently. Therefore, many solid silicone products that cannot be encapsulated currently use liquid molding.
Food-grade liquid silicone is made of platinum catalyst, and the processing technology of the product should be the current high-quality category. So what are its outstanding advantages?
Liquid silicone has transparency, strong tear resistance, resilience, yellow resistance, thermal stability, water resistance, good air permeability, aging resistance and weather resistance, and at the same time, it has a moderate viscosity, good fluidity, easy operation and high product transparency.
A brief description of LIMS (Liquid Silicone Rubber Injection Molding) is a method of pumping addition-curable liquid silicone rubber into an injection molding machine and curing it in the mold. Judging from the differences in the process flow and curing reaction of these two methods, LIMS has several advantages:
(1) Saving manpower: the process of material conveying, metering, mixing, injection, etc. realizes continuous automation and reduces power consumption
(2) It can improve production efficiency: and shorten the molding cycle through rapid curing.
(3) Can improve product quality: no reaction by-products, no impurities mixed in.
(4) Suitable for composite molding: Due to the good fluidity of the material, low molding pressure, and wide curing temperature range, composite molding can be performed in addition to insert molding.
