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
