Heavy Duty PA TPR PU PP Casters Industrial Stainless Steel Casters

At Ocean Century Industrial, we combine 26 years of dual expertise in high-performance injection molding and precision metal stamping to deliver robust caster systems engineered for warehouses, medical facilities, and heavy machinery applications. Our integrated manufacturing approach ensures compatibility between polymer components and stainless steel hardware, achieving unmatched durability in load-bearing and corrosive environments.

Core Manufacturing Capabilities

1. Advanced Polymer Injection Molding

Our 142-machine fleet (50T–1850T clamping force) produces caster wheels and gear components with material-specific advantages:

•  PA6/PA66 Casters: 30% glass-fiber reinforced for 500kg dynamic loads
• TPR/TPU Overmolding: 65–90 Shore A shock-absorbing treads molded onto PP hubs in single-cycle dual-shot processes.

2. Stainless Steel Stamping Expertise

300T–800T stamping presses fabricate 304/316L brackets with:

•  Laser-cut mounting plates (±0.2mm tolerance).
• Deep-drawn swivel races (4mm thickness).
• Deburring automation for Ra 0.8μm smooth edges.
• Anti-corrosion treatments: Passivation, electropolishing, or PVD coating options.

3. Hybrid Assembly Integration

 Injection Molding/Insert molding/Stamping/Riveting
