The LSR silicone valve injection mold is a high-precision tooling solution designed for manufacturing silicone valves used in medical, food, and industrial fluid control systems. This injection mold for silicone valve adopts a 16-cavity cold runner system combined with 4 cold nozzles, where each nozzle feeds four cavities, significantly optimizing mold cost while maintaining stable production efficiency.

The cold runner design ensures consistent LSR flow and minimizes material waste, delivering high repeatability and excellent dimensional accuracy. The silicone injection mold for valve components is engineered for high-volume production, producing valves with smooth surfaces, precise slit structures, and reliable sealing performance.

If medical-grade LSR materials are used, the molded products can fully meet the requirements of the medical industry, including biocompatibility and safety standards, making this LSR valve mold for medical applications suitable for healthcare and pharmaceutical use.

Description

Silicone valves are widely used as one-way or control valves in medical and fluid systems, effectively regulating liquid or air flow and preventing backflow or leakage.

Thanks to the excellent elasticity, chemical resistance, and biocompatibility of LSR, these valves can maintain stable performance under repeated compression and harsh environments.

This injection mold for silicone valve is specifically designed for high-precision valve structures such as umbrella valves and slit valves. Compared with traditional rubber processing, the silicone injection mold for valve components offers faster cycle times, higher consistency, and minimal flash.

The 16-cavity layout combined with a 4-nozzle cold runner system allows one nozzle to supply four products, significantly reducing tooling cost while ensuring balanced material distribution. This LSR valve mold for medical applications is ideal for large-scale production of valves used in medical devices, liquid dispensing systems, and food-grade applications.

In addition, the precision silicone valve injection tooling can be customized according to different valve designs, sizes, and functional requirements.
