Our Rubber Compression Mould is a precision-engineered tool designed for high-volume production of custom rubber components (including EPDM, NBR, silicone, and NR parts). Built from high-grade tool steel, it delivers consistent dimensional accuracy, durable performance, and reliable results under high-temperature and high-pressure compression molding processes.

Performance
· Multi-Cavity Design: The mould (as shown) features a multi-cavity layout (8 cavities in this example) to maximize production efficiency and reduce per-unit costs.
· High Pressure & Temperature Resistance: Designed to operate at pressures up to 20–30 MPa and temperatures up to 180–220°C, compatible with most rubber curing processes.
· Uniform Heat Distribution: Optimized runner and venting systems ensure even heat transfer, preventing under-curing or over-curing of rubber parts.
· Precision Dimensional Control: Tight machining tolerances (±0.01mm) guarantee consistent part dimensions across all cavities and production runs.
· Easy Demoulding: Precision parting lines and ejection mechanisms (threaded cores visible in the image) allow for smooth removal of finished rubber parts without deformation.
· Long Service Life: Wear-resistant tool steel and surface treatments ensure a mould life of ≥ 500,000 cycles with proper maintenance.
