Introduction of liquid silicone injection molding

Silicone injection molding, liquid silicone rubber is added to adapt the process to develop a class of injection molded silicone rubber varieties, with labor-saving, forming curing cycle is short, no environmental pollution. 　　After curing the liquid silicone rubber injection molding, the mixing performance even up to the level of silicone rubber. Some mixing silicone liquid injectable silicone has turned and used auto parts, cable accessories, insulator sheds, copiers plastic, household appliances parts, various gaskets, bottle mouth, buttons and other products processing. In general, injection molding silicone rubber two-component packaging liquid or paste form, A, B component materials were mixed at 1:1, the two components should have the same viscosity and density; vulcanizing temperature according to the thickness of the molded article and to determine the shape, typically in the range of 80 degrees to 170 degrees vulcanization molding, the vulcanization temperature is suitable to make 139 degrees Celsius to 170 degrees Celsius; one injection pressure, liquid silicone injection molding and general characteristics can be low compared to the plastic molding, in the 3-12Pa remote site can be filled in the mold; 3 vulcanization injection molding cycle, after the 150 ° C under 1mm molded product, an operating time is only 10 seconds silence. 　　LIM formulated silica-based material, can be obtained by taking the amount of high-silica-filled, good mobility liquid silicone molding to produce primary colors. Approach generally taken as silica scene, then driven low boiling heat treatment, and then diluted with a base polymer processing methods. 　　Typically, the keys with a liquid silicone rubber injection molding, requiring hardness, tensile strength, elongation, tear strength, yield and outside the wire compression ratio and other technical indicators, stretch attrition rate is a very important in use performance indicators. 　　Injectable silicone mold, requires good dimensional stability, good mold release, temperature and strong (250 degrees Celsius), the line generally yield less than 0.1%. ; Stretch, high tear strength, depth of cure at 200 ° C temperature resistant reversion. 　　Further, with the bottle mouth LIM silicone formulation, in addition to the keys with the same silicone rubber has good transparency, suitable hardness than, higher tensile strength and tear strength, but also has a very good resistance to buckling resistance, stretching fatigue resistance. Curing speed is usually completed within a one-time 20 to 30 seconds, the molding cycle is not more than one minute, money, effort, energy efficient. Molding pressure is low, measurement standards, high precision molds, products, no flash and defects, saving raw materials, the performance can be comparable with HTV glue. Labor costs can be reduced by half. 　　Want to learn more about silicone injection molding, injection of liquid silicone, liquid silicone injection, such as injection Gui rubber series, please visit URL :// www.szrl.net expert free advice hotline: 400 -779-4008, you can also send us an email info@szrl.net., we will provide you with a professional answer.
