Produced in stainless steel by Aunov Tech, the Wiper motor enclosure is formed and machined on the same floor. In operation, the wiper motor housing carries the wiper motor internals and locates the output gear. Drawing, cutting and measurement sit on one floor, keeping first-article quality through scheduled runs without handing the part to another vendor.
Product overview
What matters most on this metal enclosure is, the formed envelope, flatness and hole location, audited against the approved sample at each production release.
Die work and machining for this metal enclosure sit on the same floor, so a drawing change is absorbed in one step, and the same die can be re-cut from the original data.
How it is manufactured
Every metal enclosure follows the same routed path: Drawing converts a flat blank into the finished envelope in one controlled sequence; secondary machining holds the seats, threads and faces that forming cannot produce.
The tooling record is stored against the part number, and the same setup is reused on the next call-off.
Materials and finishing
Base materials in stock: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and the grade agreed for this metal enclosure is carbon steel or stainless.
Because the part faces weather and wash cycles, the coating is chosen for durability: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. The agreed finish for this metal enclosure travels with the part number on every reorder.
Production is compared with the approved sample every run, so the colour and grain of the finish stay stable.
Quality control
The factory operates with ISO 9001 certification: mill certificates cover every delivery of stock, first articles are measured on a CMM, and later batches follow the sampling plan agreed at approval. For the wiper motor housing, output-shaft bore runout is checked on every first article, and seal seats are gauged for burr-free assembly. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the report is packed with the shipment.
Where the part is used
The metal enclosure is fitted into automotive sub-assemblies and adjacent equipment in both OEM and aftermarket supply.
Drawings for this metal enclosure are adapted across programmes, so the specification is set by the toughest of them, without a second tooling round.
Specifications
| Item | Wiper motor enclosure |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – unusual walls, threads or tolerances are feasibility-checked first; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Progressive and drawing dies are designed and built in house, so tooling lead time stays under our control, and maintenance is tracked against the part number. |
| Samples | Pre-production samples come with a full inspection report, so any deviation is corrected at sample stage, 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 enclosure. |
| Surface finish | Phosphating for coating adhesion, then powder coating, e-coating or zinc plating; chrome and nickel for visible faces. |
| Processing | Coil blanking, progressive drawing through 3-5 stages with anneals between, trim and pierce, then deburr and finish. |
| Equipment | Mechanical presses from 5 to 250 T, hydraulic presses 250-500 T, annealing ovens, plus CNC turning and machining centres. |
| Tolerance | +/-0.1 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 or L/C, quoted in USD or EUR; sea or air freight is quoted to your door. |
