Liquid injection moulding silicone rubber for sili...

The liquid injection silicone with non-toxic, heat resistance, high resilience and flexible is an electrometric material, which can be cured heavily and quickly and is suitable for the production of repetition and mechanization. The silicone accessories using the material of moulding silicone rubber with excellent performance of waterproof, flame retardant, high temperature, electrical conductivity, abrasion resistance, oil resistance, ozone resistance, weather aging, is appropriate for thermo-mechanical sealing pad. In addition, the silicone accessories can make the insulation products and medical silicone products because of no toxicity. This article will focus on the injection molding process of liquid injection silicone for silicone accessories.   The moulding silicone rubber for silicone accessories has characteristics of high temperature resistant, acid and alkali resistance, low shrinkage rate, and has passed the certification of environmental FDA. The hardness of liquid injection silicone can be adjusted by the performance of silicone accessories products.     Applications of moulding silicone rubber for silicone accessories: The liquid injection silicone is mainly used for health supplies, automobiles and auto parts, baby supplies, medical supplies, kitchen appliances, sports equipment, electronic products and toys, food mold, goggles, silicone products, seals and special purpose products.   Making silicone accessories with liquid injection silicone: 1. First of all, you need to have an injection molding machine, which is also called as injection machine or mixing machine, and it must be dedicated for the operation of moulding silicone rubber.   2. Liquid injection moulding silicone rubber contains two components, A part and B part. The mixing ratio of 1:1 is most conducive to injection. In addition, as this requirement of product design, this operation of addition and measurement of color is necessary. Various colors can be achieved according to the needs of customers, and the most common colors are red, blue, and yellow. Here, please note some heavy metal paint containing organic tin, such as N, P, S, will cause this phenomenon of not curing of liquid injection silicone.   3. A+B two parts moulding silicone rubber for silicone accessories that is hydraulic and extrusive from two pipes of A and B, color enter into the plasticizing system after being mixed evenly and fully, and the plasticizing screws have the function of homogenizing and mixing. Then, The mixture of liquid injection silicone is injected into the mold with high temperature (170-200 ℃) by the screw, and the curing reaction of moulding silicone rubber for silicone accessories is beginning to form.   4. When the liquid injection silicone reaches the cold flow system, it is worth noting that the flow channel is required cold enough. In order to avoid missing moulding silicone rubber, needle valve is mounted on the surface of the mold parts. Please seal the silicone mouth immediately after the completion of injection. Then, the silicone accessories is molding.   Shenzhen Hong Ye Jie Technology Co., Ltd is the global leading moulding silicone rubber manufacturer.
