1. The extrusion molding process is like squeezing toothpaste. The head of silica gel extrusion equipment is also the cross-sectional shape of the product and has a certain length. Due to pressure and temperature, the products coming out of the machine have been vulcanized. The products processed by this process are generally strip products, and the cross sections of products can be various, such as rectangular strips and annular silicone tubes. 2. The glue dropping process can also drop out silica gel products, but this process requires liquid silica gel to be placed in a syringe, and the raw materials are dropped on the mold through pneumatic and manual operations, and then heated and vulcanized. This process is a manual process, which requires more manpower and low productivity. But it also has a more important feature, that is, the products made by this process can drop out many colors according to the requirements, and the dropped silica gel products are also exquisite and concave and convex. What we do is more silicone bracelets of various colors, silicone mobile phone cases of various colors and patterns, and various exquisite cartoon silicone key chains and other small pendants.
