Aunov Tech supplies the Metal stamping wiper motor housing as a stainless steel component manufactured entirely in house. In the assembly, the wiper motor housing drives the link and blade assembly through a geared output shaft. Forming and machining share equipment, staff and batch records, so the approved sample defines every later batch without re-quoting the job elsewhere.
Product overview
This metal housing is defined by, the formed envelope, flatness and hole location, recorded on the inspection report for every batch.
Die building, pressing and machining for this metal housing are all in house, so revisions do not wait on outside suppliers, with process data archived for repeat orders.
Production route
The route for this metal housing is fixed and repeatable: Progressive dies blank, form and pierce from coil in one pass; deburring and finishing are completed before packing.
Each run is logged against the drawing revision, so process settings are reused rather than re-invented.
Materials and surface finish
Standard stock includes carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and the grade agreed for this metal housing is carbon steel or stainless.
Because the part faces weather and wash cycles, the coating is chosen for durability: plating, anodising, powder coating, electrophoresis and passivation. Once approved, the finish for this metal housing is fixed and does not get re-decided.
Production batches are gauged to the signed first article, so the colour and grain of the finish stay stable.
Quality control
Quality management is certified to ISO 9001: material traceability starts with mill certificates, the CMM measures the first article dimension by dimension, and routine sampling keeps batches aligned with the first article. At wiper motor housing level, output-shaft bore runout is checked on every first article, and seal seats are gauged for burr-free assembly. Tests for torque, leakage or pressure can be arranged when the service demands them, and results travel with the batch paperwork.
Applications
This metal housing is used in vehicle and under-bonnet assemblies in both OEM and aftermarket supply.
One drawing for this metal housing is commonly applied to several programmes, so the specification is set by the toughest of them, and the drawing stays common.
Specifications
| Item | Metal stamping wiper motor housing |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – samples are reverse-measured into a controlled drawing; the approved drawing is kept as the controlled master. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so die cost stays transparent, and first-article timing is measured from the tooling start date. |
| Samples | Samples are issued for approval before the run, so the approved first article becomes the gauge reference, 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 housing. |
| Surface finish | Phosphating for coating adhesion, then powder coating, e-coating or zinc plating; chrome and nickel for visible faces. |
| Processing | Progressive stamping with in-die piercing and forming, followed by deburring, tumbling and surface treatment. |
| Equipment | Progressive presses 25-200 T, decoilers and coil feeders, vibratory finishing lines and a full in-house toolroom. |
| Tolerance | +/-0.15 mm typical on formed parts, +/-0.3 mm on large covers; the die decides the achievable band. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, payment by T/T, L/C at sight or D/P; each volume tier carries its own quoted price. |
Also known as: metal forming wiper motor housings and metal fabricated wiper motor housings — same part, same tooling, only the drawing reference differs.
