Aunov Tech manufactures the Auto starter motor cabinet in stainless steel on a single production floor. On the product, the starter motor housing locates the brush plate and absorbs the torque reaction at cranking. The same floor forms, machines and inspects the part, which keeps tolerances consistent from sample to volume on one production route.
Product overview
What matters most on this metal component is, material grade, wall uniformity and thread position, all held to the drawing and verified at first article.
The press shop and machine shop that make this metal component share one floor, so a drawing change is absorbed in one step, and nothing about the route depends on a third party.
How it is manufactured
Manufacturing runs on a controlled process path: Drawing runs from flat blank to finished envelope in one controlled sequence; after drawing, critical faces are machined and the part is degreased and gauged.
Each shipment is traceable to the signed first article, so process settings are reused rather than re-invented.
Materials and surface finish
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: polishing, plating in zinc, nickel or chrome, anodising, powder coating, electrophoresis and passivation. Once approved, the finish for this metal component is fixed and does not get re-decided.
Production is compared with the approved sample every run, so the colour and grain of the finish stay stable.
Quality control and inspection
The factory operates with ISO 9001 certification: certificates verify each incoming batch of material, first articles are measured on a CMM, and every production run is inspected against the first-article report. 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. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the report is packed with the shipment.
Applications
This metal component normally works inside vehicle and under-bonnet assemblies across automotive, appliance and industrial programmes.
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 the die does not have to change.
Specifications
| Item | Auto starter motor cabinet |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – DFM notes are returned before any tooling is cut; the same drawing is used for every repeat order. |
| Tooling | Die design and toolmaking stay in house, so the die charge appears as its own quotation line, and the die remains dedicated to your part. |
| Samples | Prototype and pre-production samples are provided against the drawing, so any deviation is corrected at sample stage, and mass production is gated on that approval. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this component. |
| Surface finish | Zinc or nickel plating for corrosion, plus powder coating or electrophoresis on housings; laser etching on request. |
| Processing | Coil blanking, progressive drawing through 3-5 stages with anneals between, trim and pierce, then deburr and finish. |
| Equipment | 5-250 T mechanical presses and 250-500 T hydraulic presses, in-line annealing furnace, CNC turning for secondary work. |
| Tolerance | +/-0.03 mm on machined features, +/-0.1 mm on formed ones, with first-article inspection report. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, T/T with deposit and L/C for larger runs; repeat orders reuse the approved first article. |
