Insert-Molded Single-Throated Worm Gear

Manufacturing Processes & Capabilities

• Precision Single-Throated Profile Tooling: Utilizes high-precision CNC EDM to fabricate tooling for concave throat curves, ensuring accurate throated tooth contours and precise meshing engagement with mating worm shafts.

• Coaxial Insert Molding & Demolding Optimization: Precision fixtures secure the metal shaft during insert injection of engineering plastics; specialized ejection mechanisms eliminate tooth stress, deformation, or surface dragging during demolding.

Features & Advantages

• Increased Contact Ratio & Wear Resistance: The single-throated concave contour closely wraps around the mating worm, expanding the contact surface area to distribute contact stress and substantially enhance wear resistance and torque capacity.

• Smooth Transmission, Low Backlash & High Shear Strength: The metal core ensures rigid shear and bending resistance, while the enveloping tooth geometry delivers quiet, steady power transmission and minimal backlash for compact reduction gearboxes.
