Our Rubber Tube Mold is a precision-engineered tool designed for the high-volume production of rubber tubes (including EPDM, silicone, and NBR tubes). Constructed from high-grade tool steel, it ensures consistent dimensional accuracy, surface finish, and durability for continuous rubber molding operations.

Performance
Precision Dimensional Control: Multi-cavity design (as shown in the image) enables simultaneous production of multiple rubber tubes with consistent wall thickness, length, and profile.
High Wear Resistance: Hardened steel surfaces resist abrasion from rubber compounds, maintaining mould integrity over thousands of molding cycles.
Efficient Thermal Conductivity: Optimized mould design ensures uniform heat distribution during curing, reducing cycle time and improving product quality.
Easy Demoulding: Precision-machined parting lines and ejection mechanisms (threaded cores, as visible) allow for smooth removal of finished rubber tubes without deformation.
Customizable Cavity Design: Can be tailored to produce tubes of various shapes (straight, corrugated, branched) and sizes to meet specific application requirements.
Application
· Automotive Industry: Production of coolant hoses, vacuum tubes, and fuel system tubes for engine and chassis systems.
· Industrial Machinery: Manufacturing of hydraulic/pneumatic hoses, conveyor tubes, and sealing tubes for industrial equipment.
· HVAC & Plumbing: Fabrication of heat-resistant air ducts, water drainage tubes, and insulation tubes for building systems.
· Medical & Healthcare: Production of silicone-based medical tubes (e.g., drainage tubes, respiratory tubing) for medical devices.
· Consumer Goods: Manufacturing of appliance hoses (washing machines, dishwashers) and garden/utility tubes.
