LSR for making silicone baby bottle

LSR is short for liquid silicone rubber, which is a silicone raw material used for making mold and LSR products. LSR products are commonly used to replace plastic articles for daily use, because the LSR has the characteristics of good elasticity, waterproof, moisture resistance, resistant to acid, alkali and other chemicals, for example, LSR silicone baby bottle is a hot and popular liquid silicone products. Today I'd like to introduce the injection molding process of making silicone baby bottle and the factors that affect the operation to you.   Description of LSR for making silicone baby bottle: LSR is organic silicone material with non-toxic, transparent, thermosetting, heat resistant, and high resilience flexible. The behavior of vulcanizing is mainly characterized by low viscosity, fast curing, high shear thinned and thermal expansion coefficient. LSR for making silicone baby bottle is well suited to injection molding process.     Injection molding operation for LSR silicone baby bottle: 1. First, you must have the injection moulding machine, which also called injection machine. 2. Injection machine has two pipes after hydraulic extrusion, converging into a pipe (A part and B part has mixed evenly), and you can also add the color into the mixture. Then, you will get cured elastomers after heating.   Factors associated with making silicone baby bottle: 1. Curing temperature: The most suitable curing temperature of LSR silicone baby bottle is different according to the thickness and shape of products. But the standard temperature is in the range of 130-200 ℃, and in general it can shape even within 90-120 ℃.   2. Injecting pressure: In general, it can gain good effect by using injection molding technology when the curing temperature of LSR silicone baby bottle is 130-200 ℃, and the pressure in 40-120 kg/cm2.   3. Curing time: The curing time of LSR is within 10 seconds in 150 ℃ when thickness of molding product is about 1 mm. So silicone baby bottle can be formed in a very short period according to its thickness.   4. Line shrinkage: When the temperature is in the range of 100-150 ℃, the line shrinkage rate of LSR silicone baby bottle is 2% to 3%.   5. Using period (after mixing): Its useful life of LSR for making silicone baby bottle is related to temperature when two components were mixed, but the molding viscosity is not affected for ordinary products under the condition of normal temperature 25 ℃. If it is necessary to extend the effective service life, we recommend that you install a cooling device in the mixed area.   Shenzhen Hong Ye Jie Technology Co., Ltd is a science and technology corporation, which is absorbed in production, R & D, and sales of LSR (liquid silicone rubber). Since its establishment, our company with the superiority of more professional LSR raw material for silicone baby bottle, more attentive service and more affordable price has won a lot of praises from our domestic and foreign customers. Any our LSR silicone baby bottle can be replaced in the three months after purchase if there is any quality problem.
