Aluminum Bushing Insert-Molded Helical Gear

Manufacturing Processes & Capabilities

• Precision Bushing In-Mold Positioning & Anti-Deformation Molding: Incorporates lightweight knurled aluminum bushings secured by high-precision mold locating pins; precisely calibrated injection and holding pressures eliminate thin-wall bushing collapse or inner-diameter shrinkage.
• Low-Stress Mold Flow & Helical Demolding Mechanism: Multi-gate optimization and mold temperature management minimize interfacial thermal stress between aluminum and plastic, while precision rotating unscrewing mechanisms ensure flawless tooth profile release without surface damage or runout.

Features & Advantages

• Lightweight Design & Superior Torque Retention: The high-strength, low-density aluminum sleeve combined with outer knurling delivers strong mechanical interlocking, maximizing torsional resistance for lightweight drivetrain designs.
• Wear Resistance & Anti-Bore Deformation: The aluminum bushing interface withstands continuous rotational and axial friction, preventing direct bore wear, elongation, or heat degradation common in pure plastic hubs; helical tooth gearing ensures quiet, smooth power transmission.
