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 Send your drawing/specs and quantity plan—we’ll confirm the exact lead time and a milestone schedule in the quotation.
