Industrial Drive Coated Wheel Injection Molding

This disc-shaped component features a central shaft hole and radially distributed outer flanges. It serves as a core drive or guide wheel in automated conveyor lines, AGVs, and packaging machinery. The wide-flange design increases ground contact area to distribute loads, while the internal metal bearing core ensures low-friction rotation. This makes it ideal for mobile equipment requiring quiet operation, vibration damping, and floor protection.

Precision manufacturing focuses on controlling shrinkage consistency during injection molding to ensure tight tolerances for the central bore (for secure bearing/shaft fit) and high roundness of the outer diameter (to prevent runout at high speeds). For thick-walled designs with reinforcing ribs, we optimize gate locations and cooling systems to eliminate sink marks, ensuring structural rigidity and dimensional stability under radial loads.

Leveraging our Ningbo facility’s mature injection molding capabilities, including Haitian machines and Coordinate Measuring Machines (CMM), we support mass production using engineering plastics such as PA66 GF30, POM, or Polyurethane. We also offer one-stop solutions from mold development to final assembly for complex structures involving metal insert overmolding or two-color molding. Please provide 2D/3D drawings specifying material grades, hardness requirements, and key fitting tolerances. We will evaluate quotes and lead times based on mold complexity, material costs, and inspection standards.
