The Sheet metal forming wiper motor housing is produced by Aunov Tech from stainless steel, formed and finished under one roof. In duty, the wiper motor housing drives the link and blade assembly through a geared output shaft. Die work, machining and CMM inspection are all in-house, so repeat orders stay aligned with the approved sample with no third party in the loop.
Product overview
The drawing for this metal housing fixes, wall thickness control, flange geometry and the sealing surface, audited against the approved sample at each production release.
Die work and machining for this metal housing sit on the same floor, so the route from print to sample stays short, with process data archived for repeat orders.
From coil to finished part
Every metal housing follows the same routed path: Blanks are drawn in stages, with interstage annealing where the wall thins; threads are single-pointed or rolled and seats bored in one setup where possible.
Batch records are filed against the part number, and the same setup is reused on the next call-off.
Materials and finishing
Working stock covers cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze with carbon steel or stainless specified on the drawing for this metal housing.
The coating is matched to the working environment: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. Once approved, the finish for this metal housing is fixed and does not get re-decided.
Repeat orders are gauged back to the approved first article, and material certificates are kept per batch.
Quality control and inspection
Production runs under an ISO 9001 certified quality system: stock arrivals are checked against mill certificates, a full CMM report approves the first article, and production batches are inspected on a sampling plan. 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, with certificates included in the shipment file.
Typical applications
This metal housing is used in automotive sub-assemblies and adjacent equipment in both OEM and aftermarket supply.
This metal housing is supplied to several positions in the same machine, so a single grade and coating can cover each application, and approvals carry across programmes.
Specifications
| Item | Sheet metal forming wiper motor housing |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – DFM notes are returned before any tooling is cut; changes are priced before they are made. |
| Tooling | Progressive and drawing dies are designed and built in house, so tooling lead time stays under our control, and first-article timing is measured from the tooling start date. |
| Samples | Pre-production samples come with a full inspection report, so the approved first article becomes the gauge reference, and the signed sample is kept for future reorders. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this housing. |
| Surface finish | Phosphating for coating adhesion, then powder coating, e-coating or zinc plating; chrome and nickel for visible faces. |
| Processing | Deep drawing from coil or blank, with in-process annealing so walls thin evenly; trim, pierce, form and finish. |
| Equipment | Mechanical presses from 5 to 250 T, hydraulic presses 250-500 T, annealing ovens, plus CNC turning and machining centres. |
| Tolerance | +/-0.15 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, payment by T/T or L/C, quoted in USD or EUR; each volume tier carries its own quoted price. |
