Aunov Tech supplies the Car starter electric motor accessories as a stainless steel component manufactured entirely in house. In the assembly, the starter motor housing aligns the solenoid and drive pinion while shielding the windings. Forming, machining and inspection share one floor, so first-article dimensions hold through volume batches without a second supplier involved.
Product overview
What defines this metal component is, the formed envelope, flatness and hole location, audited against the approved sample at each production release.
The press shop and machine shop that make this metal component share one floor, so revisions do not wait on outside suppliers, and the same die can be re-cut from the original data.
How it is manufactured
The route for this metal component is fixed and repeatable: Coil is blanked and then drawn down in successive stages; wall thickness is checked at the thinnest section after forming.
Repeat car starter electric orders are measured against the approved sample, so neither material nor finish drifts between lots. Mill certificates are filed per heat, so car starter electric traceability survives a change of material batch.
Materials and finishing
Our stock list runs to cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze with carbon steel or stainless specified on the drawing for this metal component.
The coating is matched to the working environment: zinc and nickel plating, chrome, anodising, powder coating and passivation. The agreed finish for this metal component travels with the part number on every reorder.

Quality control
Quality management is certified to ISO 9001: certificates verify each incoming batch of material, the CMM measures the first article dimension by dimension, and run inspections follow an agreed sampling plan. On the starter motor housing itself, bore-to-pilot concentricity is measured on a CMM at first article, and every run is gauged for flange flatness. Functional testing – torque, leak or pressure – can be written into the plan, with certificates included in the shipment file.
Typical applications
The metal component is fitted into vehicle and under-bonnet assemblies in both OEM and aftermarket supply.
A single design of this metal component is often reused across a product family, so wall bands and finishes are selected to cover the widest duty, and approvals carry across programmes.
Specifications
| Item | Car starter electric motor accessories |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – DFM notes are returned before any tooling is cut; the approved drawing is kept as the controlled master. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so a die can be re-cut against the approved drawing, and first-article timing is measured from the tooling start date. |
| Samples | Sample lead time is quoted with the order, and the approved sample governs the run. |
| Materials | Stock covers carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass; the final grade is fixed with the drawing review. |
| Surface finish | Plating, coating or polishing to suit the drawing; the finish is inspected with the dimensional report on the first article. |
| Processing | Multi-stage deep drawing with interstage annealing, trimmed and pierced in following dies; every stage is logged against your part number. |
| Equipment | Press shop running 5-250 T mechanical and 250-500 T hydraulic presses, annealing ovens on site, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.05 mm to +/-0.1 mm across the part, wall thickness held to print; finer bands confirmed from capability data before quoting. |
| Delivery terms | Delivery quoted per Incoterms 2020 – FOB, CIF or DDP – by sea or air, to your address. |
