Why choose liquid silicone rubber(LSR)?
LSR provides a “magic combination” of characterization, process and performance that helps scale
Optional design range for small parts, complex designs, high precision and overmolding:
1. Two-component; 1:1 mix ratio
2. Easy to mix
3. Rapid heat cure
Key features of cured LSR include good mechanical properties and excellent weather resistance,
Extreme temperature tolerance and aging resistance.
Liquid fluorosilicone rubber (F-LSR) combines excellent fuel and oil resistance with
Economics of LSR processing.
We are a professional liquid silicone products manufacturer . Our liquid silicone rubber products basically use injection molding processing technology:
what is Injection molding liquid silicone rubber?
Injection molding liquid silicone rubber (LSR) is a type of addition-type liquid silicone rubber. It takes advantage of its low viscosity (it has certain fluidity and irregularity before vulcanization) and is easy to feed with metering and mixing equipment. Special injection molding equipment accurately and automatically feeds, mixes, and injects the two components, and then quickly vulcanizes them to form the product. The injection molding process has gradually replaced the traditional molding process and has many advantages: the liquid injection molding process is used for vulcanization molding, with accurate measurement and less material waste; the vulcanization temperature is low, the molding product cycle is short, and the production cost is reduced; the product is high-precision and can be processed complexly Shaped products; no by-products in the vulcanization process, no need for secondary vulcanization; products with excellent aging resistance, weather resistance, non-toxicity, high transparency, high mechanical strength, good elasticity and other characteristics. Therefore, liquid injection molded silicone rubber has become the first choice material in the fields of daily rubber products such as baby products, daily products, electrical insulation material processing, cabinet accessories manufacturing and other fields. It is one of the fastest growing products in silicone rubber.
The liquid silicone rubber injection molding process is as follows:
the two liquid silicone rubber raw materials A and B are accurately measured and transported to the mixing device through the metering device; the two components are fully mixed in the mixer and then transported to the injection molding machine; through The molding machine injects or sprays into preheated multiple molds and distributes them evenly into each mold cavity; in the hot mold cavity, the silicone rubber material is heated and quickly vulcanized to form the product; after vulcanization, the mold is automatically opened and ejected; and then the mold is closed. And enter the next molding cycle. The entire molding cycle takes from tens of seconds to several minutes, and the molding cycle varies depending on the size of the product. The entire process flow is as shown below.
