Something You Need to Know About Liquid Silicone Rubber Injection Molding


What’s LSR injection molding?

Liquid silicone rubber injection molding technology (LIM) is a new and efficient silicone rubber molding method developed at the end of the 1970s. It is a combination of liquid silicone rubber with excellent performance and injection molding equipment, thus forming a new silicone rubber molding processing technology. This processing technology can achieve the purpose of simplifying the process, shortening the processing time, saving materials and improving efficiency. And the production process basically does not produce waste, is conducive to environmental protection.

How does LSR molding work?

The liquid silicone rubber raw material is injected or sprayed into the preheated multiple molds by the molding machine and evenly distributed to each mold cavity. In the hot mold cavity, the silicone rubber material is heated and rapidly vulcanized to form the products. After vulcanization molding, the mold is automatically opened and out of the mold, and then the mold is closed to enter the next molding cycle. The whole molding cycle is from tens of seconds to a few minutes, and the molding cycle is different according to the size of the products. Below pictue shows that how it is work.

The advantages of LSR molding

Compare traditional molding technology, the LSR injection molding process has become more and more popular in marketing. It has following advantages:

1.The use of liquid injection molding process vulcanization molding, accurate measurement, less material waste;

2.Low vulcanization temperature, short molding cycle, reduce production cost; High precision products, can process complex shape products;

3.Curing process without by-products, no need for two-stage curing;

4.Products with excellent aging resistance, weather resistance, non-toxicity, high transparency, high mechanical strength, good elasticity and other characteristics.


The applications of LSR molding

Liquid silicone rubber injection molding has thousands of applications in a variety of industries, including medical, automotive, kitchen appliances, baby care, aerospace, electronics and many other specialty industries. Silicone rubber products with its unique advantages are widely loved by people.
