Aunov Tech manufactures the Car starter electric motor cover in stainless steel on a single production floor. On the product, the starter motor housing aligns the solenoid and drive pinion while shielding the windings. Die work, machining and CMM inspection are all in-house, keeping first-article quality through scheduled runs under one roof.
Product overview
What defines this metal cover is, wall thickness control, flange geometry and the sealing surface, recorded on the inspection report for every batch.
Die building, pressing and machining for this metal cover are all in house, which keeps revision loops short and samples fast, and every step is logged against the part number.
From coil to finished part
Production of this metal cover is locked to one route: Drawing runs from flat blank to finished envelope in one controlled sequence; flanges and rims are formed in the same line, then trimmed to length.
Most of the difficulty in a car starter electric is invisible: wall consistency, concentricity, burr control. Any drift in the car starter electric process is corrected at the machine, not sorted out at inspection.
Materials and finishing
Our stock list runs to cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and this metal cover runs in carbon steel or stainless.
Coating selection follows the duty – indoor, outdoor or under-hood: plating, anodising, powder coating, electrophoresis and passivation. The agreed finish for this metal cover travels with the part number on every reorder.
Production batches of the car starter electric are gauged back to the signed first article, not to a memory of it. Any change to the car starter electric drawing is re-approved and re-verified before production continues.
Quality control
Production runs under an ISO 9001 certified quality system: mill certificates cover every delivery of stock, the first article is CMM-measured against the print, and routine sampling keeps batches aligned with the first article. 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. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the inspection report ships with each batch.
Applications
This metal cover is used in automotive sub-assemblies and adjacent equipment for customers who own the drawing and the tooling.
A single design of this metal cover is often reused across a product family, so a single grade and coating can cover each application, and cost per piece stays at the volume tier.
Specifications
| Item | Car starter electric motor cover |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – unusual walls, threads or tolerances are feasibility-checked first; changes are priced before they are made. |
| Tooling | Die design and toolmaking stay in house, so tooling lead time stays under our control, and the die remains dedicated to your part. |
| Samples | Pre-production samples come with a full inspection report, so the part is proven before it is made in volume, and the signed sample is kept for future reorders. |
| Materials | Stock runs to carbon steel, 304 / 316 stainless, aluminium and brass; special grades are sourced to the drawing when volumes justify. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; the finish is inspected with the dimensional report on the first article. |
| Processing | Progressive drawing through several stages, annealed between draws, then trim and pierce; first articles verify the whole flow before the run is released. |
| Equipment | Mechanical presses from 5 to 250 T and hydraulic presses 250-500 T, with in-line annealing furnaces; first articles and batch samples are checked on the CMM. |
| Tolerance | +/-0.03 mm on turned secondary features, +/-0.1 mm on as-drawn walls; finer bands confirmed from capability data before quoting. |
| Delivery terms | Incoterms FOB as standard with DDP on request; sea and air options priced with the order. |
