Characteristics of liquid silica gel:
Liquid silica gel is a non-toxic, heat-resistant, and flexible thermosetting material with high resilience. silicone moulding process Its rheological behavior is mainly manifested by low viscosity, fast curing, shear thinning and high thermal expansion coefficient. Its products are characterized by good thermal stability, cold resistance, excellent electrical insulation properties, and will not produce toxic substances when burned; therefore, it is used in health products, automobiles, silicone baby bottles, medical products, diving products, silicone kitchenware and Silicone pads have become irreplaceable materials in the production design.

Molding process:
Liquid silica gel is a two-component liquid material, divided into A component and B component. The work of the mixer fully mixes the A component and the B component in a precise 1:1 ratio. And because some of the products are of colored design, it is equipped with a color pump set and a color metering part. The A+B components, additives, colors, etc. enter the plasticizing system after being fully mixed. This plasticizing screw has the functions of homogenization and mixing at the same time. The mixture is injected into the hot mold through the screw, and the silica gel undergoes a curing reaction at a mold temperature of 170 to 200°C. When using a cold runner system, it is worth noting that the runner should be cold enough. In order to avoid glue leakage, the needle valve is installed on the surface of the mold part. When the glue injection is completed, the needle valve immediately closes the injection nozzle.
