Liquid silicone has excellent transparency, tear resistance, resilience, anti-yellowing, thermal stability, water resistance, good air permeability, heat aging resistance and weather resistance, while moderate viscosity, good fluidity, easy to operate, transparent products high sex.
Utilizing the various properties of liquid silicone, injection molding liquid silicone can also be widely used in various industries represented by electrical, electronics, automobiles, aerospace, machinery, food, daily necessities, medical care, and family planning supplies. Injection molding liquid silicone focuses on the improvement of production capacity and the reduction of labor costs, which perfectly reduces the cost of products. In recent years, the Liquid Rubber Injection Molding Method (LIMS), that is, the injection molding of liquid silicone rubber, has been widely popularized and promoted. Recently, this method has become a molding method that people in the industry generally pay attention to because of its advantages of automatic molding in a short time and composite molding with plastics.
Liquid Injection Molding of Silicone Rubber
The liquid silicone rubber injection molding method that started in the 1970s has gradually become popular, and is now recognized as a molding method for silicone rubber. First, the commonly used LIMS method will be explained.
If you use one sentence to explain LIMS (Liquid Silicone Rubber Injection Molding), it is a method of pumping addition-curable liquid silicone rubber into the 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) Save manpower:
The process of material conveying, metering, mixing, injection and so on realizes continuous automation and reduces power consumption.
(2) Can improve production efficiency:
Shorten the molding cycle by rapid curing.
(3) Can improve product quality:
No reaction by-products are generated, and no impurities are mixed.
(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.
