Advanced EPDM Vulcanization and High-Strength Metallurgy

The structural integrity of every CARPARTNER crankshaft pulley is achieved through the integration of two critical components: a precision-cast body and a high-performance damping ring, fused via an advanced industrial process.

Material & Process Excellence by CARPARTNER

• High-Strength Ductile Iron: We utilize premium ductile iron (QT500-7) for the pulley body to ensure maximum anti-fatigue strength and structural integrity under constant mechanical stress.
• Premium EPDM Rubber: Our damping rings utilize high-grade EPDM (Ethylene Propylene Diene Monomer), offering extreme heat resistance (up to 150°C), ozone resistance, and excellent weatherability to prevent the rubber from hardening or cracking.
• Integral Vulcanization: A hallmark of CARPARTNER’s mature craftsmanship is the integral vulcanization process performed under specific pressure and temperature, guaranteeing a permanent, failsafe bond between metal and rubber.
• Precision Testing: Each unit undergoes CNC machining and electronic dynamic balancing to ensure zero-vibration performance across the entire RPM range.
