Custom Mold Tooling for silicone LSR Shower Head Accessories

"Custom Mold Tooling for silicone LSR Shower Head Accessories" refers to tailor-made molds used for producing shower head accessories such as nozzles and seals, typically made from liquid silicone rubber (LSR) to ensure durability, heat resistance, and waterproofing. Surface treatments for these accessories may include coating, polishing, sandblasting, and laser engraving, which enhance durability, aesthetics,

LSR Over-molding Shower Head Mold Design

Due to the high expansion coefficient of LSR, expansion occurs when heated, while slight contraction occurs when cooled

This part cannot maintain accurate margin in the die. Therefore, cold runner processing can be used, and LSR should be protected

With lower temperature and fluidity, the cold runner USES a closed system, in the injection cycle, the closed system in each

Each flow channel adopts “sealing needle” or “needle valve” to control the accurate measurement of LSR material.

Liquid Silicone Rubber is a kind of non-toxic, heat-resistant and highly resilient flexibility. The rheological behavior of thermosetting materials is mainly characterized by low viscosity, rapid curing, thinning shear and higher Coefficient of thermal expansion. LSR is a dual-liquid rapid vulcanization material with platinum as catalyst, which can be used in injection molding. Mass, rapid vulcanization, repetitive mechanical production.
