What gear precision class can Wolfer achieve?

Wolfer routinely produces ISO 1328 Class 6 hobbed gears and ISO 1328 Class 5 ground gears. Class 5 requires gear-grinding after heat treatment and adds roughly 5–7 days to the lead time.

What is the maximum gear outside diameter?

Standard envelope is up to Ø 600 mm OD. For larger gears (up to Ø 1,200 mm) we use the large-machine bay at our Foshan plant — please share the drawing for a feasibility check.

Do you make plastic gears?

Yes — we machine acetal (POM) and PA66 nylon gears for low-noise, dry-running applications. We also injection-mold plastic gears via partner tooling for higher volumes.
