Silicone rubber is a two-component, synthetic, flexible rubber-like substance made from silicone elastomers which can be treated at room temperature on some first elastomer used in molding. It's heat resistant, durable and free from allergens or leachable substances. Liquid silicone resembles regular silicone but contains different processing attributes. It's bought as a two-part raw material using a grease-like viscosity.
Nowadays selvol of liquid silicon rubber is growing more and more critical. One reason for this is the higher performance demands of the completed articles. Additionally, an increasing number of manufacturers of rubber components see advantages in the high degree of productivity and automation.
Numerous Methods of silicon molding:
Molding procedures employed by suppliers of silicon molding services include cast molding, compression molding, dip molding, injection molding, reaction injection molding, rotational molding and transfer molding.
Sometimes at the cast molding process, the liquid material is poured into an open mold, in compression molding a slug of silicone is pressed between 2-heated mold halves. On the other hand dip molding is a procedure very similar to hot dip coating, where the final item is the fused plastisol stripped out of your dipped mold.
But in injection molding, liquid silicone is forced into a cooled mold under tremendous pressure. At the Reaction Injection Molding (RIM) process two or more reactive chemicals are mixed at high speed as they are being injected into a mold. In rotational molding hollow molds full of silicone material are secured into pipe-like spokes that extend from a central hub. In transfer molding, both mold halves are clamped together, and pressure forces silicone to the mold.
Silicon rubber molding has come a very long way over the previous two decades. From its origins in a couple of special programs in which superior physical properties depended over the premium cost, this thermo group carved out a small but steady market in the automotive and medical fields.
