This Auto starter motor can is an Aunov Tech production part in stainless steel, quoted and built to customer print. In operation, the starter motor housing aligns the solenoid and drive pinion while shielding the windings. The same floor forms, machines and inspects the part, which keeps tolerances consistent from sample to volume with no third party in the loop.
Product overview
For this metal can, the drawing centres on, wall thinning, concentricity and the finished mating faces, all held to the drawing and verified at first article.
The press shop and machine shop that make this metal can share one floor, so a change of wall or hole does not restart the programme, and the same die can be re-cut from the original data.
How it is manufactured
The route for this metal can is fixed and repeatable: Drawing runs from flat blank to finished envelope in one controlled sequence; the part is annealed between stages so the wall thins evenly.
Batch records are filed against the part number, so reorders match the samples you already approved.
Materials and finishing
Our stock list runs to carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and the grade agreed for this metal can is carbon steel or stainless.
Coating selection follows the duty – indoor, outdoor or under-hood: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. The finish on this metal can is locked to the drawing revision, so later orders match.
Production batches are gauged to the signed first article, and material certificates are kept per batch.
Quality control
Quality management is certified to ISO 9001: stock arrivals are checked against mill certificates, a full CMM report approves the first article, and routine sampling keeps batches aligned with the first article. 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. Tests for torque, leakage or pressure can be arranged when the service demands them, and the inspection report ships with each batch.
Applications
This metal can is used in vehicle and under-bonnet assemblies in both OEM and aftermarket supply.
A single design of this metal can is often reused across a product family, so a single grade and coating can cover each application, and no re-tooling is needed.
Specifications
| Item | Auto starter motor can |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – a manufacturability review comes back with the quotation; the same drawing is used for every repeat order. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so a die can be re-cut against the approved drawing, and first-article timing is measured from the tooling start date. |
| Samples | Prototype and pre-production samples are provided against the drawing, so the approved first article becomes the gauge reference, 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 can. |
| Surface finish | Phosphating for coating adhesion, then powder coating, e-coating or zinc plating; chrome and nickel for visible faces. |
| Processing | Deep drawing from coil or blank, with in-process annealing so walls thin evenly; trim, pierce, form and finish. |
| Equipment | Mechanical presses from 5 to 250 T, hydraulic presses 250-500 T, annealing ovens, plus CNC turning and machining centres. |
| Tolerance | +/-0.15 mm typical on formed parts, +/-0.3 mm on large covers; the die decides the achievable band. |
| Delivery terms | FOB Ningbo or Shanghai, payment by T/T, L/C at sight or D/P; repeat orders reuse the approved first article. |
