Produced in stainless steel by Aunov Tech, the Auto starter electric motor shield housing is formed and machined on the same floor. In operation, the starter motor housing locates the brush plate and absorbs the torque reaction at cranking. Forming and machining share equipment, staff and batch records, so repeat orders stay aligned with the approved sample on one production route.
Product overview
What defines this metal housing is, the formed envelope, flatness and hole location, each measured at first article and gauged on production batches.
Die work and machining for this metal housing sit on the same floor, which keeps revision loops short and samples fast, and the approved sample is kept as the master.
How the part is produced
This is how the metal housing is built: Blanks are drawn in stages, with interstage annealing where the wall thins; piercing and trimming are done in the same die line.
Batch records for the auto starter electric are filed against the part number, so process settings are reused instead of re-invented. That record is what every auto starter electric reorder is built on, so nothing changes silently between shipments.
Materials and finishing
Everything is drawn from a fixed stock list: cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and the grade agreed for this metal housing is carbon steel or stainless.
Coating selection follows the duty – indoor, outdoor or under-hood: zinc and nickel plating, chrome, anodising, powder coating and passivation. The agreed finish for this metal housing travels with the part number on every reorder.
Production batches of the auto starter electric are gauged back to the signed first article, not to a memory of it. First article, drawing revision and material cert travel with each auto starter electric batch.
Quality control and inspection
The plant is ISO 9001 certified: incoming material is verified against mill certificates, a full CMM report approves the first article, and later batches follow the sampling plan agreed at approval. For the starter motor housing, 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 report is packed with the shipment.
Applications
This metal housing is used in automotive assemblies and under-hood equipment for OEM and Tier-1 customers.
Drawings for this metal housing are adapted across programmes, so the tightest tolerance in the family sets the spec, and the drawing stays common.
Specifications
| Item | Auto starter electric motor shield housing |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – a manufacturability review comes back with the quotation; the agreed version governs every later batch. |
| Tooling | Tooling is built and held under your part number, so tooling lead time stays under our control, and first-article timing is measured from the tooling start date. |
| Samples | Sample parts are measured and reported before submission, so the approved first article becomes the gauge reference, and later batches are gauged back to the signed sample. |
| Materials | Materials held include carbon steel, 304 / 316 stainless, aluminium and brass; material substitutes are proposed only with your written approval. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; finish thickness and adhesion checked on the first article. |
| Processing | Multi-stage deep drawing with interstage annealing, trimmed and pierced in following dies; 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, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.05 mm to +/-0.1 mm across the part, wall thickness held to print; capability is checked on the first article before the run continues. |
| Delivery terms | Shipping terms are set with the order: FOB, CIF or DDP, T/T or L/C, door delivery quoted. |
