INDUSTRY COMPONENT

Seals/Gaskets

Specialized sealing components for water-cooled molds that prevent coolant leakage and maintain thermal management integrity in industrial molding processes.

Component Specifications

Definition
Seals and gaskets designed specifically for water-cooled mold applications, engineered to withstand thermal cycling, pressure differentials, and chemical exposure from cooling fluids while maintaining precise dimensional stability and preventing contamination of the molding process.
Working Principle
These components create a physical barrier between cooling channels and mold surfaces through compression and material deformation, utilizing elastomeric or composite materials that maintain sealing integrity under thermal expansion/contraction cycles and hydraulic pressure variations.
Materials
Typically manufactured from fluorocarbon elastomers (FKM/Viton), ethylene propylene diene monomer (EPDM), silicone rubber, or PTFE-based composites with temperature resistance from -40°C to 200°C and chemical compatibility with water-glycol mixtures and corrosion inhibitors.
