How long is the production cycle?

How long is the production cycle?

Core Answer

For OEM repeat parts with existing tooling/fixtures, our typical production cycle is about 15 days.
For custom gears requiring new tooling, samples usually take ~30 days, and mass production typically takes 15–30 days, depending on specifications and approval steps.
Note: In manufacturing, lead time usually includes setup/changeover, processing, waiting between operations, and final inspection—so it will vary with process route and inspection scope.

Typical Timelines

Order Type
What It Means
Typical Timing
OEM / repeat production
Tooling and process route already validated
~15 days
Custom gear – samples
New tooling/fixtures/cutters + first-article inspection
~30 days
Custom gear – mass production
After sample approval (and PPAP if required)
15–30 days

What Can Change The Timeline

• Tooling status: new cutters/fixtures/gauges required or not (new tooling adds time)

• Process route: heat treatment + grinding + gear inspection steps (more steps = longer cycle)

• Quality/approval requirements: FAI, full dimensional report, gear profile/lead report, PPAP submission level (if required)

• Order volume & schedule slot: batch size and capacity reservation on critical processes (heat treat / grinding / gear inspection)

How We Keep Lead Time On Track

• Lock drawing revision and confirm critical characteristics before release

• Milestone schedule: tooling/DFM → sample → approval → mass production (owners + checkpoints)

• Capacity reservation on bottleneck operations (heat treatment, grinding, gear inspection)

• First-article approval before batch release, and QA sign-off before shipmentLock drawing revision and confirm critical characteristics before release

What We Need From You To Confirm Lead Time Quickly

• Drawing/3D (or sample) + material & heat treatment requirement

• Gear spec: module/DP, teeth, accuracy grade (ISO/DIN/AGMA), hardness/case depth target

• Quantity (trial + annual volume) and target Incoterms (FOB/DDP)

• Any required documents: COC/material cert/heat-treat report/gear measurement charts/PPAP
