Produced in stainless steel by Aunov Tech, the Deep Drawn Wiper Motor Housing is formed and machined on the same floor. On the product, the wiper motor housing protects the motor windings while the output shaft takes the wipe load. Forming, machining and inspection share one floor, keeping first-article quality through scheduled runs without a second supplier involved.
Product overview
The specification of this metal housing turns on, wall thinning, concentricity and the finished mating faces, audited against the approved sample at each production release.
Forming, machining and finishing for this metal housing happen on one site, so a change of wall or hole does not restart the programme, with process data archived for repeat orders.
How it is manufactured
This is how the metal housing is built: Coil is blanked and then drawn down in successive stages; piercing and trimming are done in the same die line.
Route cards follow every order through the shop, so process settings are reused rather than re-invented.
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 housing 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. It is written into the drawing for this metal housing, so it cannot drift between batches.
Repeat orders are gauged back to the approved first article, and grade changes have to be agreed in writing first.
Quality control
The plant is ISO 9001 certified: certificates verify each incoming batch of material, the first article is CMM-measured against the print, and run inspections follow an agreed sampling plan. 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.
Where the part is used
The metal housing is fitted into automotive assemblies and under-hood equipment for OEM and Tier-1 customers.
One part number for this metal housing frequently serves several assemblies, so wall bands and finishes are selected to cover the widest duty, and the drawing stays common.
Specifications
| Item | Deep Drawn Wiper Motor Housing |
|---|---|
| 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 | Die design and toolmaking stay in house, so a die can be re-cut against the approved drawing, and the charge is refundable against agreed volumes. |
| Samples | Samples are issued for approval before the run, so the sample is retained as the master, and later batches are gauged back to the signed sample. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this housing. |
| Surface finish | Zinc / nickel / chrome plating or e-coat, chosen for the environment this housing sees; salt-spray tested to drawing. |
| 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 | +/-0.1 mm on formed features and +/-0.2 mm on overall lengths; tighter bands confirmed against the die before quoting. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, T/T or L/C, with D/P accepted on repeat business; repeat orders reuse the approved first article. |
