Introduction – Why Wheel Quality Matters in Luggage Design
For luggage manufacturers and ODM/OEM buyers, wheels are more than a finishing detail. The durability of your luggage caster wheels directly affects smooth mobility, product lifespan, warranty cost, and brand perception. Many low-cost soft PU wheels tend to peel off or crack after frequent use, especially under heavy loads and temperature changes. Choosing a truly durable caster ensures long-term reliability and customer satisfaction.
Material Comparison: PU vs TPR vs PVC
When you compare luggage wheel materials, PU (polyurethane), TPR (thermoplastic rubber) and PVC (polyvinyl chloride) show clear differences in endurance, elasticity, and peel-off risk:
| Material | Durability | Elasticity | Peel-off Resistance | Noise Level | Typical Use |
|---|---|---|---|---|---|
| PU (Polyurethane) | ★★★★★ | High | Excellent (One-Time Injection prevents peeling) | Quiet | Premium luggage & travel gear |
| TPR (Thermoplastic Rubber) | ★★★★☆ | Medium | Good | Quiet | Mid-range luggage |
| PVC (Polyvinyl Chloride) | ★★☆☆☆ | Low | Weak | Moderate | Budget luggage |
Innovative Solution: One-Time Injection PU Caster
At Enjoying Go Co., Ltd., our patented One-Time Injection PU Caster fuses the PU tire and nylon core in a single molding process. This creates a seamless bond that resists separation and surface cracking while maintaining elasticity.
- Zero risk of tire peel-off
- Enhanced load capacity and deformation resistance
- Long-lasting elasticity for smooth rolling
