Aunov Tech supplies the Wiper motor cabinet as a stainless steel component manufactured entirely in house. In duty, the wiper motor housing drives the link and blade assembly through a geared output shaft. Forming, machining and inspection share one floor, keeping first-article quality through scheduled runs without handing the part to another vendor.
Product overview
The drawing for this metal component fixes, draw depth, wall band and the surfaces that forming cannot hold, all held to the drawing and verified at first article.
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, and the approved sample is kept as the master.
From coil to finished part
Production of this metal component is locked to one route: The shell is drawn from a blank in successive stages, annealed where the wall thins; flanges and rims are formed in the same line, then trimmed to length.
Each run is logged against the drawing revision, and the same setup is reused on the next call-off.
Materials and finishing
Materials kept on the floor cover carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this metal component is costed in carbon steel or stainless.
The finish is chosen for the environment the part sees: 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.
Repeat orders are gauged back to the approved first article, so neither material nor finish drifts between lots.
Quality control
Quality management is certified to ISO 9001: mill certificates cover every delivery of stock, first articles are measured on a CMM, and run inspections follow an agreed sampling plan. At wiper motor housing level, 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 results travel with the batch paperwork.
Applications
This metal component normally works inside automotive assemblies and under-hood equipment for customers who buy to drawing.
The same metal component is often run in more than one assembly, so a single grade and coating can cover each application, and the drawing stays common.
Specifications
| Item | Wiper motor cabinet |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – samples are reverse-measured into a controlled drawing; the agreed version governs every later batch. |
| Tooling | Die design and toolmaking stay in house, so the die charge appears as its own quotation line, and maintenance is tracked against the part number. |
| Samples | First-article samples ship with a dimensional report and material certificate, so any deviation is corrected at sample stage, 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 component. |
| Surface finish | Zinc or nickel plating for corrosion, plus powder coating or electrophoresis on housings; laser etching on request. |
| Processing | Coil blanking, progressive drawing through 3-5 stages with anneals between, trim and pierce, then deburr 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, payment by T/T or L/C, quoted in USD or EUR; call-off schedules are supported. |
