Today I will tell you it is injection molded like this .
Liquid Silicone Rubber is a two-component liquid material divided into A component and B component . The mixer works by mixing the A component and the B component in a precise 1:1 ratio . Because some products are colored , they are equipped with a color pump set and a color metering part .The A+B components , additives , colors , ect .are thoroughly mixed and then enter the plasticizing system .
The plasticizing screw has the function of homogenization and mixing , and the mixture is injected into the hot mold though a screw , and the curing reactor of the Liquid Silicone Rubber occurs at a mold temperature of 170 to 200 Centigrade .When using a cold runner is system ,it is worth noting that the runner system ,it is worth nothing that the rubber is cold enough .In order to avoid leakage of glue , the needle valve is mounted on the surface of the mold part , and when the injection is completed ,the needle valve immediately closes the nozzle .
