Oil-Impregnated Bushing Insert-Molded Plastic Gear

Manufacturing Processes & Capabilities

• Precision In-Mold Alignment & Anti-Flash Sealing: High-precision mold locating pins secure the porous oil-impregnated bronze bushing via its bore and datum faces, ensuring tight concentricity and sealing against molten resin entering the inner diameter or surface pores.
• Low Thermal-Stress Molding & Oil Retention: Regulated mold temperatures and optimized injection pressure curves minimize thermal transfer, preventing internal lubricant degradation or bleed-out during molding while preserving inner bore roundness and oil-retention capability.

Features & Advantages

• Maintenance-Free Self-Lubrication & Low Friction: The porous metal matrix releases a continuous hydrodynamic oil film during operation, providing outstanding wear resistance, anti-galling performance, and maintenance-free longevity.
• Quiet Transmission & Streamlined Assembly: Combines the vibration dampening of plastic gear teeth with the smooth, low-friction sliding of the oilite bushing to minimize running noise; integrated insert molding eliminates secondary press-fit operations and tolerance stack-up.
