Aunov Tech builds this Wiper motor case in stainless steel, from coil or bar through to the finished surfaces. Once installed, the wiper motor housing protects the motor windings while the output shaft takes the wipe load. Forming and machining share equipment, staff and batch records, so repeat orders stay aligned with the approved sample without a second supplier involved.
Product overview
For this metal case, the drawing centres on, wall thinning, concentricity and the finished mating faces, controlled from the approved first article onward.
Toolroom, presses and machining centres used on this metal case operate on the same site, which keeps the sample loop inside our own schedule, and the die record stays with your part number.
How it is manufactured
The process for this metal case runs in a fixed sequence: Blanks are drawn in stages, with interstage annealing where the wall thins; flanges and rims are formed in the same line, then trimmed to length.
Each shipment is traceable to the signed first article, so nothing depends on the operator remembering.
Materials and finishing
Everything is drawn from a fixed stock list: carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this metal case is costed in carbon steel or stainless.
The finish is chosen for the environment the part sees: polishing, zinc / nickel / chrome plating, anodising or powder coating. It is fixed on the drawing for this metal case, so repeat orders never reopen the question.
Each shipment is verified against the master sample, so material and finish stay consistent between shipments.
Quality control and inspection
Quality management is certified to ISO 9001: material traceability starts with mill certificates, the first article is CMM-measured against the print, and routine sampling keeps batches aligned with the first article. For the wiper motor housing, output-shaft bore runout is checked on every first article, and seal seats are gauged for burr-free assembly. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the inspection report ships with each batch.
Typical applications
The metal case is fitted into automotive assemblies and under-hood equipment for OEM and Tier-1 customers.
This metal case is supplied to several positions in the same machine, so one tooling set serves every position, and the drawing stays common.
Specifications
| Item | Wiper motor case |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – DFM notes are returned before any tooling is cut; changes are priced before they are made. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so no tooling step is outsourced, and the charge is refundable against agreed volumes. |
| Samples | Sample parts are measured and reported before submission, so the part is proven before it is made in volume, and later batches are gauged back to the signed sample. |
| Materials | Stock covers carbon steel, 304 / 316 stainless, aluminium and brass; the final grade is fixed with the drawing review. |
| Surface finish | Zinc / nickel / chrome plating or e-coat, chosen for the environment this housing sees; salt-spray tested to drawing. |
| Processing | Deep drawing from coil or blank, with in-process annealing so walls thin evenly; trim, pierce, form and finish. |
| Equipment | 5-250 T mechanical presses and 250-500 T hydraulic presses, in-line annealing furnace, CNC turning for secondary work. |
| Tolerance | +/-0.05 mm on controlled dimensions and +/-0.1 mm on general features; capability studies supplied on request. |
| Delivery terms | FOB Ningbo or Shanghai, T/T or L/C, with D/P accepted on repeat business; call-off schedules are supported. |
Also known as: wiper motor boxes — same part, same tooling, only the drawing reference differs.
