Air Trap Defect in Liquid Silicone Injection Molding VentingAir Trap as well as gas trap, a common problem during Liquid Silicone Injection Molding, is the root cause of bubbles, voids and blisters, short shot visible on molded part, which are mainly caused by unreasonable mold venting system and pa

How to Avoid Air Trapping Issue on Liquid Injection Molding (LIM) Production?

Silicone over-molding is a process that an existing part in different material usually a plastic, metal or silicone part that overmoled with liquid silicone rubber in LSR injection molding pricess. LSR overmolding widely used in medical areas, electronic devices. For example, a silicone over-molding

How a duckbill valve works?-- LSR Silicone Duckbill Valve for Breast Pump

Silicone Molding, also known as silicone compression molding or rubber compression molding, is a very common processing technique for manufacturing silicone rubber parts, which is feeding solid silicone raw material mixed with vulcanizing agent in the mold, through a certain period of high temperatu

Liquid Silicone Injection Mold without Shut-off ValvesLiquid silicone injection mold without shut-off valves, similar to edge-injection-gate plastic injection mold. Because Liquid silicone & lsr products by silicone injection molding without shut-off valves will have big injection gate mark or flow

Transfer Moulding is converted from compression moulding and take advantages of injection molding. Rubber transfer moulded parts are more precise and more consistent than Compression Moulding parts. Compared with Liquid Silicone Injection Moulding, Transfer Moulding is rather cost-effective and easy development. To know more about why the transfer rubber products are more accurate than traditional compression molded parts.

Transfer Molding, Compression Molding, Rubber Injection Molding or Liquid Silicone Injection Molding? Which is right to your silicone rubber projects. Compression molding is a economical and simple rubber molding, which designed to place blocky-shape rubber materials (granular & pelletized shape) in mold chambers & cavities to be molded by heat and pressure. Compression molded manufacturing process like making waffles & cake mold.
Rubber Transfer Molding Design is similar to rubber compression molding, but there is a pot on the top plate and a ram above the pot. This mold pot is used to contain pre-measured rubber raw material and transfer it to the cavities through pot runner and spruced.
