Custom Size ABS/PS/TPU Plastic Caster Parts Overmolding Gear Bulk OEM

Ocean Century Industrial leverages 26 years of advanced overmolding expertise to deliver precision caster systems that combine durability, load capacity, and chemical resistance. As a vertically integrated manufacturer, we specialize in high-volume production of custom-sized gear assemblies (5mm–100mm diameters) for appliance assembly, material handling equipment, medical carts

Core Manufacturing Processes

1. Injection Molding for Polymer Components

Material Options:

• Glass-fiber reinforced PP (20% GF) for load-bearing feet (up to 150kg/unit).
• TPE overmolded ABS for anti-vibration gaskets (Shore A 70±5).

Tooling & Efficiency:

• Multi-cavity molds (32 cavities) with 500,000+ cycle lifespan.
• Hot-runner systems reducing material waste by 18%.

2. Hybrid Assembly Techniques

Insert Molding: Bonding stamped threads into PA66 bases

3. Customization Capabilities

Height Adjustment Range: 15–60mm (±0.5mm gradation marks).

Load Capacity Scaling: 50–300kg dynamic load configurations.

Quality Assurance Protocols

• Dimensional Validation: 3D laser scanning for 0.05mm flatness on mounting surfaces.
• Environmental Testing: Salt spray test on metal components / Load Endurance
