Production of liquid silicone products. At present, CL-26AB glue is applied to metal or plastic substrates, dried and then put into the mold to heat, and the amount of liquid silica gel for injection molding is calculated. Heat vulcanization molding at about 90℃-120℃. Temperature, curing time, exhaust, equipment debugging, etc. all need attention


Liquid silicone needs to be produced by an injection machine. It is mainly used for baby products, medical products and electronic products (keys). There is also a type of A/B mixed directly into the mold, and then baked in the oven (for silicone prosthetic milk) Production and operation methods), as well as the silica gel used to make liquid silicone rollers, trademark glue, etc., depending on which product you use. Generally, liquid silica gel is used after vulcanization, but it can also be used as a filler, such as electrical insulation filler, or liquid silicone filler for breast augmentation, or as an additive in cosmetics.


Characteristics of liquid silicone injection molding machine Liquid silicone is a non-toxic, heat-resistant, and highly resilient, flexible thermosetting material. Its rheological behavior is mainly manifested in low viscosity, fast curing, shear thinning, and high thermal expansion coefficient. LSR is a two-liquid rapid vulcanization material with platinum as a catalyst. It can be produced by injection molding, mass, rapid vulcanization, and repetitive mechanical production. Its products are characterized by good thermal stability, cold resistance, excellent electrical insulation properties, and no toxic substances are produced during combustion. Therefore, it has become an irreplaceable material in the production design of health products, automobiles, baby products, medical products, diving products, kitchen appliances, and seals.
