Among the products processed by
Injection Molding, there are liquid silica gel and solid silica gel. The appearance difference between the two products is not obvious. The following aspects will introduce the difference and comparison between the two.
1. Distinguish from application fields
Liquid silicone is generally used in baby products and kitchen products, which can directly contact food and human body, so it is necessary to choose food grade as injection molding material. Solid silica gel is generally used in daily necessities, industrial miscellaneous parts, and auto parts. Stability of liquid silica gel and solid silica gel: Liquid silica gel is a food-grade material with high transparency and high transparency. No auxiliary materials such as vulcanizing agents are added during molding, and it is sealed and fed into molding. Solid silica gel is a transparent material. When molding, it is necessary to add a vulcanizing agent to speed up the vulcanization molding time, and open the
Mold for feeding molding.
2. Distinguish from precision molds and injection molding finished products
Liquid silicone products have high transparency, no peculiar smell, and the product has a plastic injection port. The transparent bottom of solid silica gel has vulcanizing agent or other fragrance covering the vulcanizing agent, and the product has no glue injection port.
