This is because in Injection molding, a machine will mix together liquid silicone along with a catalyst. Catalyst plays a vital role here, as it helps to change form of the silicone and make hard (Solid). After the mixing process, the mixture is put into a mold, which is a container that has the shape of the final product. Combine and cool to room temperature: relative solid. When the silicone rubber cools and hardens, you have to open up the mold and remove the new product carefully. Rega (yixing) silicone injection molding can be done in cycles of very fast repetitions to create identical objects.

 

Despite some of the qualities that make liquid silicone rubber as a prime candidate for use an injection molding material. Complete flexibility: This is hands-down its greatest asset. This can be crushed, stretched and curved but not broken. This is quite helpful when you are working on intricate, elaborate designs. It is also thermal, cold and chemical resistant so it is great for products that need to withstand harsh conditions (for example kitchen utensils that get hot or things left outside in rain).


Benefits and Drawbacks of Using Liquid Silicone Rubber in Injection Moulding

But, with liquid silicone, rubber injection molding also some difficulties you will face because it’s most major the issue is mixing and injecting need to be handled very carefully. When casting into a mold it is crucial that the correct amount of silicone and catalyst are mixed together otherwise part might not set correctly or be very weak – brittle, breakable or simply not usable. Moreover, liquid silicone is a relatively high-cost material comparing to materials that more commonly used for injection molding which reflected in the manufacturing cost of end product.

 

With accuracy being so critical in the mix and inject of liquid silicone rubber, the entire manufacturing process of Rega (yixing) silicone injection molding needs to be well thought out and meticulously carried through. The machine must be calibrated exactly for it to deliver the correct amounts each time. In the same light, you need to keep the mixing ratio important and never have trouble. At this, air pockets or impurities in the material may spoil the result which is why they must be eliminated. SKILLED TRADES WORKERS HAVE TO BE ON THE SITE — they have to be doing QC just to certify the work is completed correctly.
