Injection molding silicone rubber for making goggl...

Injection molding silicone rubber for making goggles is a kind of addition cure silicone rubber. To make a pair of goggles it will go through the injection molding process. The injection molding process can be completely automatic without secondary processing. This kind of molding silicone vulcanize under heat and pressure.     Injection molding silicone rubber for making goggles contains part A and part B with equal portion(1 : 1 by weight). This ratio is very favorable for operation and it can achieve low unit costs but super quality product. Its compression set is very low and it possesses good stability and ability of resisting high temperature or low temperature. The tear strength of the injection molding silicone rubber is above 35 kN/m, what’s more, it is highly transparent and its shrinkage is extremely low. The temperature resistant range of this kind of molding silicone rubber is -60 ℃ to 250 ℃. Do you know the liquid injection molding process for making goggles? In the following I will show you a brief process of injection molding which you can regard as a reference. Prepare the 2 part addition cure silicone rubber. The two components of the silicone rubber will be pumped through static mixer by a metering pump. Coloring paste or some other additives could be added too before materials go into the static mixer part. Inside the static mixer, component A and component B will be fully mixed up and then shifted to the cooling metering part of the mold making machine.From the metering part of the mold making machine, the mixture will be pushed through the cooled sprue and runner systems to a heated antrum and the vulcanization process takes place here. The cold runner and cooling prevent the loss of materials in the feed line. Shenzhen Hong Ye Jie technology Co.
