Why is liquid silicone recommended?

In the production process of customized silicone products, the process of the silicone product determines its value and market. Currently, liquid injection molding and solid molding processes are relatively common processing methods, and food-grade liquid silicone is made of platinum catalysts. The processing technology of the product can be said to be of the highest quality at present. For those who understand the processing process of silicone rubber products, as long as they can accept the production and processing costs, they will basically choose the liquid silicone process. What are the choices? What are its outstanding advantages?

Liquid silicone has transparency, strong tear resistance, resilience, yellowing resistance, thermal stability, water resistance, good air permeability, aging resistance and weather resistance. It also has moderate viscosity, good fluidity, easy operation and high product transparency. .

Liquid injection molding of liquid silicone rubber. The liquid silicone rubber injection molding method started in the 1970s and has gradually become popular. Today, it has been recognized as a molding method of silicone rubber. First, the commonly used LIMS method will be explained.

To explain LIMS (liquid silicone rubber injection molding) in one sentence, it is a method that uses a pump to transport addition-curing liquid silicone rubber into an injection molding machine and solidifies it in the mold. Judging from the differences in the process flow and curing reactions of these two methods, LIMS has several advantages:

(1) Save manpower: The processes of material transportation, metering, mixing, injection, etc. are continuously automated to reduce power consumption.

(2) Can improve production efficiency: seek to shorten the molding cycle through rapid curing.

(3) Can improve product quality: no reaction by-products are generated, and no impurities are mixed in

(4) Suitable for composite molding: Due to the good fluidity of the material, low molding pressure, and wide curing temperature range, in addition to insert molding, composite molding can also be performed.
