Material and blank
Steel grade, blank size, availability and machinability affect material usage, preparation and cycle time. A special alloy may also require a less common process route.

What factors most affect the price of precision gears—material, heat treatment, or accuracy grade?
Material, heat treatment and accuracy are only the starting point
The biggest cost driver depends on the design and use case. Material affects stock and machinability; geometry affects setup and cutting time; heat treatment adds processing and distortion-control work; accuracy grade increases finishing and inspection requirements. Quantity, packaging and delivery scope then change the unit-price economics.
PairGears explains the main custom precision gear cost factors and why a complete RFQ improves quote stability.
Heat treatment
Carburizing, hardening, tempering or other treatment adds outside processing, testing and distortion-control requirements. The target case depth and hardness matter.
Accuracy and inspection
Tighter profile, lead, runout, backlash or surface-finish limits may require grinding, more stable tooling and a deeper inspection pack.
Commercial variables that can move the unit price
- Prototype, small batch or repeat-production quantity
- Drawing completeness and reverse-engineering effort
- Tooling, fixtures and special setup requirements
- Inspection scope, sampling and report format
- Export packing, Incoterms and delivery urgency
Use the custom gear RFQ information guide to make these variables visible before comparison.
How to get a more comparable quote
Send the drawing or sample, application, quantity by phase, material, heat-treatment target, accuracy grade, inspection requirements, packing needs and destination. Ask suppliers to separate one-time tooling from recurring unit cost.
