Aunov Tech supplies the Auto Starter Motor Can 2 as a stainless steel component manufactured entirely in house. In duty, the starter motor housing aligns the solenoid and drive pinion while shielding the windings. Drawing, cutting and measurement sit on one floor, so first-article dimensions hold through volume batches on one production route.
Product overview
For this metal can, the drawing centres on, the formed envelope, flatness and hole location, re-checked whenever the drawing is revised.
Die building, pressing and machining for this metal can are all in house, which keeps revision loops short and samples fast, and every step is logged against the part number.
Production route
The route for this metal can is fixed and repeatable: Drawing runs from flat blank to finished envelope in one controlled sequence; wall thickness is checked at the thinnest section after forming.
Process settings are archived with the part number, and that record is what every reorder is built from.
Materials and finishing
Standard stock includes SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and the grade agreed for this metal can is carbon steel or stainless.
The coating is matched to the working environment: zinc and nickel plating, chrome, anodising, powder coating and passivation. The finish on this metal can is locked to the drawing revision, so later orders match.
Each shipment is verified against the master sample, with mill certificates filed per heat.
Quality control
The factory operates with ISO 9001 certification: incoming material is verified against mill certificates, the first article is CMM-measured against the print, and run inspections follow an agreed sampling plan. Part-specific checks apply as well: on the starter motor housing, bore-to-pilot concentricity is measured on a CMM at first article, and every run is gauged for flange flatness. Torque, leak and pressure tests are available where the assembly needs them, and the batch file carries the results.
Applications
The metal can sits in vehicle and under-bonnet assemblies across automotive, appliance and industrial programmes.
One drawing for this metal can is commonly applied to several programmes, so the finish is chosen to cover the harshest of them, and the die does not have to change.
Specifications
| Item | Auto Starter Motor Can 2 |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – samples are reverse-measured into a controlled drawing; the agreed version governs every later batch. |
| Tooling | Progressive and drawing dies are designed and built in house, so no tooling step is outsourced, and the charge is refundable against agreed volumes. |
| Samples | Prototype and pre-production samples are provided against the drawing, so the approved first article becomes the gauge reference, and later batches are gauged back to the signed sample. |
| Materials | Stock covers carbon steel, 304 / 316 stainless, aluminium and brass; the final grade is fixed with the drawing review. |
| Surface finish | Zinc or nickel plating for corrosion, plus powder coating or electrophoresis on housings; laser etching on request. |
| Processing | Blanking, multi-stage deep drawing with interstage annealing, trimming and piercing, coining, then finishing. |
| Equipment | Mechanical presses from 5 to 250 T, hydraulic presses 250-500 T, annealing ovens, plus CNC turning and machining centres. |
| Tolerance | +/-0.1 mm on formed features and +/-0.2 mm on overall lengths; tighter bands confirmed against the die before quoting. |
| Delivery terms | FOB Ningbo or Shanghai, payment by T/T, L/C at sight or D/P; repeat orders reuse the approved first article. |
