Aunov Tech builds this Sheet metal stamping wiper motor housing in stainless steel, from coil or bar through to the finished surfaces. Once installed, the wiper motor housing carries the wiper motor internals and locates the output gear. The same floor forms, machines and inspects the part, which keeps tolerances consistent from sample to volume without handing the part to another vendor.
Product overview
What defines this metal housing is, material grade, wall uniformity and thread position, controlled from the approved first article onward.
Toolroom, presses and machining centres used on this metal housing operate on the same site, which keeps the sample loop inside our own schedule, and the approved sample is kept as the master.
Production route
Manufacturing runs on a controlled process path: Blanking and forming run in progressive tooling; deburring and finishing are completed before packing.
Route cards follow every order through the shop, so a repeat order starts from the same approved data.
Materials and finishing
The standard stock list carries carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this metal housing is costed in carbon steel or stainless.
Coating selection follows the duty – indoor, outdoor or under-hood: electrophoresis, powder coating, anodising and zinc / nickel plating. Once approved, the finish for this metal housing is fixed and does not get re-decided.
Later runs are measured back to the first article, so the colour and grain of the finish stay stable.
Quality control
The plant is ISO 9001 certified: material traceability starts with mill certificates, first-article geometry is confirmed on the CMM, and every production run is inspected against the first-article report. Part-specific checks apply as well: on the wiper motor housing, output-shaft bore runout is checked on every first article, and seal seats are gauged for burr-free assembly. Torque, leak and pressure tests are available where the assembly needs them, and the report is packed with the shipment.
Typical applications
The metal housing is fitted into vehicle and under-bonnet assemblies for customers who own the drawing and the tooling.
Drawings for this metal housing are adapted across programmes, so wall bands and finishes are selected to cover the widest duty, and no re-tooling is needed.
Specifications
| Item | Sheet metal stamping wiper motor housing |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – DFM notes are returned before any tooling is cut; the agreed version governs every later batch. |
| Tooling | Progressive and drawing dies are designed and built in house, so tooling lead time stays under our control, and the charge is refundable against agreed volumes. |
| Samples | Samples are issued for approval before the run, so the sample is retained as the master, and the signed sample is kept for future reorders. |
| 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 | Coil feeding and progressive die blanking, forming, piercing or in-die tapping, deburring, then plating. |
| Equipment | 5-200 T progressive stamping lines with coil feeders and decoilers, toolroom wire-cut EDM for die maintenance. |
| Tolerance | +/-0.15 mm typical on formed parts, +/-0.3 mm on large covers; the die decides the achievable band. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, T/T or L/C, with D/P accepted on repeat business; price breaks tie to annual volume. |
