This product is a high-strength composite component manufactured using LSR (Liquid Silicone Rubber) overmolding on iron or carbon steel parts.

It combines the structural strength and load-bearing capacity of metal with the flexibility, sealing performance, and environmental protection of liquid silicone rubber.

The overmolding process forms a durable protective silicone layer tightly bonded to the metal surface, significantly improving resistance to vibration, impact, corrosion, and sealing failure in harsh industrial environments.

This structure is widely used in industrial equipment, mechanical assemblies, automotive systems, and protective structural components.
