Liquid Silicone Rubber Mold Design

Liquid silicone rubber molding our basic guidelines for liquid silicone rubber molding include important design considerations to help improve part moldability enhance cosmetic appearance and reduce overall production time.

Liquid silicone rubber mold design.

It requires a better thermal balance and mold temperature control. Typically silicone molding of a part requires the liquid rubber to be kept cool 5 to 25oc or 60 to 77of and then it is injected into a heated mold 170 to 210oc or 340 to 410of. While the traditional reaction injection molding rim process focuses on a pressurized impingement mixing process liquid injection molding is comprised of a mechanical mixing method that blends a two component compound together in a mold.

After the cavity fills with silicone rubber the mold opens and the thermoset part is then manually removed because of its flexible nature. We are able to manufacture molds that are capable of producing consistent parts that are as small as 0 007 grams. Engineers in melon have years of experience in mold design and making. To mold a part thermoplastic resin is heated in the barrel and injected into a cold mold.
