Briefing
Custom metal insert and LSR overmolded sealing components for liquid cooling, industrial equipment and waterproof applications. Supports precision insert molding and OEM customization.
Detailed
Product Overview
Custom metal insert + LSR overmolded sealing housings combine engineering plastic structures, metal inserts and liquid silicone rubber into one integrated component.
Through precision insert molding technology, liquid silicone is directly formed around the designed sealing area to provide flexible protection and reliable sealing performance.
This type of integrated silicone overmolding solution is suitable for liquid cooling systems, industrial fluid control components and electronic equipment requiring waterproof protection.
SiliconePlus provides drawing-based development, tooling support and mass production service.
