Process Introduction
The silicone ring for shower heads is manufactured using the Liquid
Silicone Rubber (LSR) injection molding process, featuring
flexibility, high temperature resistance, and anti-aging
properties. Installed at the shower head outlet, the silicone ring
effectively prevents scale buildup and ensures even water flow.
Material Selection
Food-grade silicone, safe, non-toxic, and heat-resistant up to
200°C.
Process Features
The LSR injection molding process allows for excellent flowability
and precise micro-pore structure formation.
Process Flow
- Silicone raw material pretreatment and mixing
- LSR injection molding to form the shower head outlet ring
- High-temperature vulcanization for durability
- Surface inspection and softness test
- Assembly test to ensure perfect fit with the shower head
