Manufacturing Processes & Capabilities

• Precision Face-Tooth Tooling & Demolding: Accommodates M0.2 to M1.5 modules with micro-tolerance tooling tailored for complex face-tooth geometries, ensuring burr-free molding and consistent tooth flank thickness.
• Flatness & Axial Runout Control: Balanced gating and mold flow optimization eliminate cooling warpage across the face disc, maintaining strict axial face runout and bore concentricity for smooth orthogonal meshing.

Features & Advantages

• 90° Crossed-Axis Drive & High Axial Tolerance: Drives standard cylindrical spur pinions at a 90° right angle; offers significantly higher tolerance to pinion axial misalignment compared to bevel gears, simplifying gearbox assembly.
• Compact Packaging & Assembly Efficiency: The flat face-tooth profile reduces overall right-angle envelope dimensions while lowering assembly alignment complexity and production costs.
• Quiet Operation, Low Friction & Self-Lubricating: High-grade POM and Nylon resins deliver low friction, vibration absorption, and self-lubricating performance, ensuring quiet and durable angular transmission under continuous duty cycles.
