This Wiper motor canister is an Aunov Tech production part in stainless steel, quoted and built to customer print. In duty, the wiper motor housing drives the link and blade assembly through a geared output shaft. Forming, machining and inspection share one floor, which keeps tolerances consistent from sample to volume under one roof.
Product overview
The drawing for this metal component fixes, wall thickness control, flange geometry and the sealing surface, controlled from the approved first article onward.
The whole route from die to finished metal component stays in house, so the route from print to sample stays short, with process data archived for repeat orders.
How it is manufactured
The route for this metal component is fixed and repeatable: Blanks are drawn in stages, with interstage annealing where the wall thins; wall thickness is checked at the thinnest section after forming.
The tooling record is stored against the part number, so nothing depends on the operator remembering.
Materials and finishing
Standard stock includes SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with carbon steel or stainless specified on the drawing for this metal component.
The finish is chosen for the environment the part sees: polishing, plating in zinc, nickel or chrome, anodising, powder coating, electrophoresis and passivation. The finish on this metal component is locked to the drawing revision, so later orders match.
Repeat orders are gauged back to the approved first article, so neither material nor finish drifts between lots.
Quality control
The factory operates with ISO 9001 certification: mill certificates cover every delivery of stock, a full CMM report approves the first article, and production batches are inspected on a sampling plan. 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. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the report is packed with the shipment.
Typical applications
The metal component is fitted into automotive sub-assemblies and adjacent equipment in volume programmes as well as aftermarket supply.
The same metal component is used across several platforms, so one approved version covers the whole range, and the die does not have to change.
Specifications
| Item | Wiper motor canister |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – unusual walls, threads or tolerances are feasibility-checked first; the same drawing is used for every repeat order. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so a die can be re-cut against the approved drawing, and the die remains dedicated to your part. |
| Samples | Prototype and pre-production samples are provided against the drawing, so any deviation is corrected at sample stage, and production starts only after your written sign-off. |
| Materials | Stock covers carbon steel, 304 / 316 stainless, aluminium and brass; the final grade is fixed with the drawing review. |
| 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 | 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, with DDP offered for EU and US addresses, T/T with deposit and L/C for larger runs; call-off schedules are supported. |
