Aunov Tech supplies the Wiper motor accessories as a stainless steel component manufactured entirely in house. On the product, the wiper motor housing protects the motor windings while the output shaft takes the wipe load. Drawing, cutting and measurement sit on one floor, so repeat orders stay aligned with the approved sample on one production route.
Product overview
The specification of this metal component turns on, material grade, wall uniformity and thread position, controlled from the approved first article onward.
Die building, pressing and machining for this metal component are all in house, so a change of wall or hole does not restart the programme, with the tooling history retained in house.
How it is manufactured
The process for this metal component runs in a fixed sequence: The drawn envelope is produced in stages with anneals between them; piercing and trimming are done in the same die line.
Route cards follow every order through the shop, and that record is what every reorder is built from.
Materials and finishing
Materials kept on the floor cover cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and this metal component is costed in carbon steel or stainless.
Because the part faces weather and wash cycles, the coating is chosen for durability: zinc and nickel plating, chrome, anodising, powder coating and passivation. The agreed finish for this metal component travels with the part number on every reorder.
Each shipment is verified against the master sample, so nothing changes silently between orders.
Quality control
An ISO 9001 certified system governs production: incoming material is verified against mill certificates, first articles are measured on a 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. Functional testing – torque, leak or pressure – can be written into the plan, with certificates included in the shipment file.
Applications
This metal component is used in automotive assemblies and under-hood equipment across automotive, appliance and industrial programmes.
This metal component is supplied to several positions in the same machine, so the tightest tolerance in the family sets the spec, and approvals carry across programmes.
Specifications
| Item | Wiper motor accessories |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – unusual walls, threads or tolerances are feasibility-checked first; changes are priced before they are made. |
| Tooling | Die design and toolmaking stay in house, so no tooling step is outsourced, and maintenance is tracked against the part number. |
| 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 | 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 | CIF or DDP, with FOB available, payment by T/T or L/C, quoted in USD or EUR; sea or air freight is quoted to your door. |
