To meet diverse industrial and market demands, we adopt multi-source rubber materials and provide customized solutions based on quality specifications. Our materials include:
- Natural Rubber (NR)
- Chloroprene Rubber (CR)
- EPDM Rubber
- HNBR Rubber
Through proprietary mixing formulations, we maximize rubber properties for enhanced durability across extreme-condition applications.
Service life of Poly V-belts varies significantly with operating conditions, environment, and temperature. Based on our environmental testing data and field experience, we provide estimated service life benchmarks for different rubber materials in heavy-duty truck engines:
- NR (Natural Rubber) PK Belts:
Service Life: 20K-30K km
- CR (Chloroprene Rubber) PK Belts
Service Life: 50K-80K km
- EPDM (Ethylene Propylene Diene Monomer) PK Belts
Service Life: 100K-150K km
These three rubbers are the most common materials for PK belts. All mileage estimates are for reference only based on standard operating conditions.
While rubber constitutes 75-90% of belt composition, these critical layers determine durability:
- Fabric Carcass Layer
Abrasion-resistant outer shield - Tensile Cord Layer
Load-bearing core for power transmission - Rubber Compound Layers
Custom-formulated adhesion/compression zones
Belt performance varies by layer configuration and material synergy – not just rubber quality.
While equipment varies by belt type, our core precision manufacturing systems ensure rubber quality control at every stage:
Equipment
- Rubber Mixing Line
- Rubber Compound Extruder
- Rotary Drum Vulcanizer
- Rope Winding Machine
- CNC Wedge Grinding
- Fixed-length Cutting
- Dynamic Fatigue Tester
All processes undergo real-time SPC monitoring with IATF 16949 quality protocols.

- Integration of Original Equipment Manufacturer (OEM) Parts Query System: supporting products such as the WEICHAI WP12 engine fan belt, belt tensioner, pulley, water pump, fan blade, and fan clutch can all be queried for OEM codes and supporting manufacturer codes.
- Raw Material Selection and Quality Control:Rubber, aluminum, and plastic are the three core raw materials for ZQ development. We strictly require quality guarantees from upstream raw material suppliers.
- Investment in Core Equipment and Molds:In-depth cooperation with contract manufacturers to share four core production equipment: rubber vulcanization, injection molding, CNC machining, and casting, and appropriate investment in production molds. This makes ZQ products more cost-competitive.
- Compliance with ZQ Quality Standards:All products must undergo batch-by-batch full inspection before leaving the factory to meet quality requirements.
