Manufacturing Processes & Capabilities

• Near-Net Shape Compacting for Complex Profiles: Accommodates diverse tooth profiles (MXL, HTD, GT series) using precision multi-action compacting tooling; controlled sintering ensures strict pitch uniformity, precise tooth cavity geometries, and smooth surface finishes.
• Concentricity & Automated Flange Assembly: Strictly controls concentricity between the bore and pitch circle to eliminate rotational runout; offers automated flange staking to secure timing belts during high-speed rotation.

Features & Advantages

• Slip-Free Precision Synchronous Drive: Meshes seamlessly with timing belts to maintain an exact transmission ratio without slippage, accommodating high initial torque and continuous forward/reverse indexing.
• High Wear Resistance & Load Capacity: Sintered metal construction delivers superior hardness and tensile strength over plastic pulleys, sustaining heavy belt tension and shock loads without tooth deformation.
• Cost Efficiency & High-Volume Consistency: Integrates complex tooth profiles, flanges, hubs, and keyways into a single compacting step, eliminating costly multi-stage machining and ensuring tight part-to-part consistency for mass production.
