Silicone molding process has a wide variety of products. In many cases, some home silicone products and silicone kitchen utensils are manufactured using two common processes. Solid and liquid are used as the molding process. The difference between the two is in different product requirements and different use environments. , such as silica gel teether, silicone adult products and some commonly used daily necessities, etc. to contact the body more secure place, solid silicone products are used for a variety of different areas, in the daily necessities, electronic silicone accessories, miscellaneous pieces of silicone, etc. can be used .
The difference and function between solid and liquid are:
Liquid silicone: liquid silicone is relatively solid high-temperature vulcanized silicone rubber, which is a liquid glue, with good fluidity, fast curing, more secure and environmentally friendly, and can fully meet the food-grade requirements.
Solid silicone: solid silicone is a kind of cell-type elastic polymer material, with high temperature resistance, cold resistance, solvent resistance, resistance to warping, anti-sticking, electrical insulation, chemical industry and other characteristics, a wider range of applications.
Comparison of solid silicone products and liquid silicone products:
Shape: As the name implies, liquid silicone is liquid and fluid. Solid silica gel is solid and has no fluidity.
Safety: Liquid silicone is a transparent, high-security, food-grade material that does not contain auxiliary materials such as vulcanizing agents, and is sealed and molded. Solid silica gel is a transparent and environmentally friendly material. It requires vulcanizing agent to cure the molding time, and is molded by open mold.
Liquid molding method:
Liquid silicone is injection-molded liquid silicone rubber (LSR): Full name is injection-molded liquid silicone rubber, and vulcanization equipment is injection molding machine.
The injection molding machine has a very simple process flow (no manual processes such as batching, compounding, cutting, and oscillating in the high-temperature glue process, and only one worker can take the product), and the product accuracy is high (all the manual processes before molding All are replaced by machines), high output (A/B glue is mixed at a certain temperature for a few seconds), many advantages such as saving people, saving electricity, and saving materials. It can produce all products produced by high temperature glue.
Solid silicone molding process:
The raw material is a solid block, and the silicone product manufacturers mix the vulcanizing agent with the color rubber through the mixing machine. The cutting machine is used to cut the finished product and mold into the appropriate size and thickness, and then put into the mold. The pressure is under a certain temperature. Molding. When demoulding and plastic products are similar, you also need to clean the mold.
How to distinguish between liquid silicone and solid silicone products: liquid silicone products have high transparency and no peculiar smell. The product has plastic injection ports, no obvious mold clamping lines and burrs, and the appearance is relatively more exquisite and seamless.
Solid silicone products have low transparency, vulcanizing agents or other odors that cover vulcanizing agents. The products do not have plastic injection openings. They are manufactured using the upper and lower molds, and the mold part of the product has a certain mold-clamping line.
