Sintered Iron Core Insert-Molded Plastic Worm Gear

Manufacturing Processes & Capabilities

• Precision In-Mold Alignment & Flash-Free Sealing: High-precision tooling fixtures rigidly secure the sintered iron core via its bore and datum faces, maintaining micron-level concentricity and perpendicularity with the outer plastic worm wheel while sealing against flash in the inner diameter.
• High-Strength Insert Molding & Profile Optimization: Tailored mold flow analysis for worm gear tooth profiles and knurled metal retention features optimizes filling and packing curves, eliminating sink marks and residual stress for accurate tooth geometry and robust mechanical interlocking.

Features & Advantages

• Heavy Torque Capacity & Torsional Shear Resistance: The rigid sintered iron hub bears direct transmission torque and radial loads, completely preventing shaft slipping, bore elongation, or hub cracking commonly seen in solid plastic worm gears under heavy duty.
• Smooth, Low-Noise Operation & Wear Resistance: The plastic worm gear teeth deliver vibration dampening and low-friction meshing against mating worm shafts, drastically reducing operational noise while ensuring durable, smooth speed reduction and long-term stability.
