Aunov Tech manufactures the Deep drawing wiper motor housing in stainless steel on a single production floor. In duty, the wiper motor housing protects the motor windings while the output shaft takes the wipe load. One production floor covers forming, finishing and inspection, so repeat orders stay aligned with the approved sample with no third party in the loop.
Product overview
The specification of this metal housing turns on, the draw ratio, corner radii and the faces that must stay flat, re-checked whenever the drawing is revised.
Forming, machining and finishing for this metal housing happen on one site, which keeps revision loops short and samples fast, and the same die can be re-cut from the original data.
How it is manufactured
Every metal housing follows the same routed path: The drawn envelope is produced in stages with anneals between them; threads are single-pointed or rolled and seats bored in one setup where possible.
Each shipment is traceable to the signed first article, so nothing depends on the operator remembering.
Materials and finishing
Standard stock includes carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper with carbon steel or stainless specified on the drawing for this metal housing.
The coating is matched to the working environment: polishing, zinc / nickel / chrome plating, anodising or powder coating. Once approved, the finish for this metal housing is fixed and does not get re-decided.
The approved sample governs later runs, so nothing changes silently between orders.
Quality control and inspection
The factory operates with ISO 9001 certification: mill certificates cover every delivery of stock, first articles are measured on a CMM, and later batches follow the sampling plan agreed at approval. 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, and the report is packed with the shipment.
Applications
The metal housing is fitted into automotive assemblies and under-hood equipment in both OEM and aftermarket supply.
One drawing for this metal housing is commonly applied to several programmes, so the tightest tolerance in the family sets the spec, and the drawing stays common.
Specifications
| Item | Deep drawing wiper motor housing |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – a manufacturability review comes back with the quotation; the approved drawing is kept as the controlled master. |
| Tooling | Tooling is built and held under your part number, so a die can be re-cut against the approved drawing, and first-article timing is measured from the tooling start date. |
| Samples | Samples are issued for approval before the run, so the sample is retained as the master, 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 | Mechanical presses from 5 to 250 T, hydraulic presses 250-500 T, annealing ovens, plus CNC turning and machining centres. |
| Tolerance | +/-0.1 mm to +/-0.2 mm general; critical features held to the drawing and verified on the first article. |
| Delivery terms | FOB Ningbo or Shanghai, payment by T/T or L/C, quoted in USD or EUR; each volume tier carries its own quoted price. |
