The characteristics of injection molding id silicone wristbands process.
Injection molding id silicone wristbands are elastomer formed by high temperature curing, suitable for injection molding process of two-component translucent liquid silicone rubber material.
1. liquid id silicone wristbands characteristics of liquid id silicone wristbands (LiquidSiliconeRubber) is a non-toxic, heat-resistant, highly resilient flexible thermosetting materials, its rheological behavior is mainly manifested in low viscosity, rapid curing, shear thinning and a high coefficient of thermal expansion. Certain fluidity, moderate springback coefficient, tensile strength ≥20KN/m, better transparency, stable shrinkage, easy injection, use temperature -60℃~250℃, good thermal stability and cold resistance LSR is a double liquid fast vulcanizing material with platinum as catalyst, which can be produced by injection molding, large quantity, fast vulcanization and repetitive mechanical production. Its products show good thermal stability and cold resistance, excellent electrical insulation performance, and no toxic substances are produced when burning, etc. 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, etc. 2. molding process LSR is a two-component liquid material, divided into component A and component B. The work of the mixer mixes component A and component B in the ratio of 1:1. The A+B component, additives and color are mixed into the plasticizing system. This plasticizing screw has the function of homogenization and mixing at the same time, and the mixture is injected into the hot mold through the screw, and the id silicone wristbands are cured and reacted at the mold temperature of 170 to 200℃. When using a cold runner system, it is worth noting that the runner should be cold enough. To avoid glue leakage, the needle valve is mounted on the surface of the mold part and the nozzle is closed by the needle valve as soon as the injection is completed.
Main characteristics The elastomer formed by high temperature curing has the following excellent properties: 1. high fluidity, high resilience, 2. high strength, high transparency, 3. key life up to 10 million times or more, 4. stable shrinkage, 5. easy to inject, excellent thermal stability and cold resistance (use temperature -60℃~250℃)
