Plastic Gears & Bushings Molding at Production Scale
Plastic gears and bushings move from the catalog to the product only when tooth geometry and wear are controlled. A gear that binds or a bushing that wears early fails the whole motion system.
Gear programs are about repeatable geometry. Cavity steel, gate location, and pack pressure set the tooth form; we verify it with gauges and CMM and hold it across the run so every gear meshes the same.
What the Capability Numbers Mean for Your Program
The specifications define the envelope in which plastic gears & bushings molding stays predictable. A press range of 50T - 400T covers parts from small precision features to larger functional components without splitting the program across vendors. Tolerances of ±0.02 mm describe where critical features are controlled rather than left to chance.
Mold life rated at 500,000 - 1,000,000 shots is a maintenance plan, not a sales figure. Tools are serviced by shot count so wear never surprises a shipment. Tooling lead time of 20 - 35 days reflects complexity and validation, and an annual capacity above 50,000,000 parts signals a floor built for sustained volume.
How a Program Runs
- Design for manufacturability. Geometry, gate location, and draft are reviewed so the part molds predictably and meets function.
- Material and tool selection. Resin grade and tool steel are chosen for the performance, volume, and life the program requires.
- Tool fabrication. The mold is machined, with hot-runner or multi-cavity features where the program specifies them.
- Molding and process setup. Parameters are developed and locked so fill, pack, and cooling stay inside the validated window.
- In-process verification. Critical dimensions are checked with gauges and CMM; results are recorded for traceability.
- Packaging and shipment. Parts are inspected, packed, and shipped against the agreed quality and delivery plan.
Material and Application Fit
Material is matched to load, speed, and lubrication; POM leads for low friction, PEEK for heat and chemical duty. We validate tooth geometry and wear on tryout.
