The Wiper motor housing is produced by Aunov Tech from stainless steel, formed and finished under one roof. Once installed, the wiper motor housing protects the motor windings while the output shaft takes the wipe load. The same floor forms, machines and inspects the part, so the approved sample defines every later batch on one production route.
Product overview
The drawing for this metal housing fixes, wall thinning, concentricity and the finished mating faces, all held to the drawing and verified at first article.
Toolroom, presses and machining centres used on this metal housing operate on the same site, so a change of wall or hole does not restart the programme, and every step is logged against the part number.
Production route
This is how the metal housing is built: The shell is drawn from a blank in successive stages, annealed where the wall thins; threads are single-pointed or rolled and seats bored in one setup where possible.
Batch records are filed against the part number, and that record is what every reorder is built from.
Materials and finishing
Our stock list runs to 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: electrophoresis, powder coating, anodising and zinc / nickel plating. The agreed finish for this metal housing travels with the part number on every reorder.
Production is compared with the approved sample every run, and grade changes have to be agreed in writing first.
Quality control and inspection
The plant is ISO 9001 certified: mill certificates cover every delivery of stock, first articles are measured on a CMM, and later batches follow the sampling plan agreed at approval. On the wiper motor housing itself, output-shaft bore runout is checked on every first article, and seal seats are gauged for burr-free assembly. Torque, leak and pressure tests are available where the assembly needs them, and the batch file carries the results.
Applications
The metal housing sits in vehicle and under-bonnet assemblies for customers who own the drawing and the tooling.
One part number for this metal housing frequently serves several assemblies, so the tightest tolerance in the family sets the spec, and the drawing stays common.
Specifications
| Item | Wiper motor housing |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – a manufacturability review comes back with the quotation; the approved drawing is kept as the controlled master. |
| Tooling | Progressive and drawing dies are designed and built 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 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 | +/-0.15 mm typical on formed parts, +/-0.3 mm on large covers; the die decides the achievable band. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, payment by T/T or L/C, quoted in USD or EUR; call-off schedules are supported. |
Also known as: wiper motor shapes — same part, same tooling, only the drawing reference differs.
