Produced in stainless steel by Aunov Tech, the Auto starter motor body is formed and machined on the same floor. In the assembly, the starter motor housing houses the armature and carries the drive-end bearing. One production floor covers forming, finishing and inspection, so the approved sample defines every later batch without handing the part to another vendor.
Product overview
What matters most on this metal component is, draw depth, wall band and the surfaces that forming cannot hold, controlled from the approved first article onward.
Toolroom, presses and machining centres used on this metal component operate on the same site, so a drawing change is absorbed in one step, and the die record stays with your part number.
How the part is produced
This is how the metal component is built: Coil is blanked and then drawn down in successive stages; the finishing operations hold the concentricity the drawing calls for.
Batch records are filed against the part number, and a reorder is a repeat, not a new start.
Materials and finishing
Materials kept on the floor cover carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper 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.
The approved sample governs later runs, so nothing changes silently between orders.
Quality control
The plant is ISO 9001 certified: mill certificates cover every delivery of stock, first articles are measured on a CMM, and production batches are inspected on a 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. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, with certificates included in the shipment file.
Applications
The metal component is fitted into automotive sub-assemblies and adjacent equipment in both OEM and aftermarket supply.
The same metal component is often run in more than one assembly, so the tightest tolerance in the family sets the spec, and the die does not have to change.
Specifications
| Item | Auto starter motor body |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – unusual walls, threads or tolerances are feasibility-checked first; the agreed version governs every later batch. |
| Tooling | Tooling is built and held under your part number, so no tooling step is outsourced, and maintenance is tracked against the part number. |
| Samples | Samples are issued for approval before the run, so any deviation is corrected at sample stage, and production starts only after your written sign-off. |
| 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 | Deep drawing from coil or blank, with in-process annealing so walls thin evenly; trim, pierce, form and finish. |
| Equipment | 5-250 T mechanical presses and 250-500 T hydraulic presses, in-line annealing furnace, CNC turning for secondary work. |
| Tolerance | +/-0.05 mm to +/-0.1 mm across the part; tighter bands confirmed against the die before the quotation is fixed. |
| Delivery terms | FOB Ningbo or Shanghai, payment by T/T or L/C, quoted in USD or EUR; call-off schedules are supported. |
