Produced in stainless steel by Aunov Tech, the Wiper Motor Housing 2 is formed and machined on the same floor. In operation, the wiper motor housing carries the wiper motor internals and locates the output gear. Forming and machining share equipment, staff and batch records, which keeps tolerances consistent from sample to volume without re-quoting the job elsewhere.
Product overview
The critical features of this metal housing are, material grade, wall uniformity and thread position, recorded on the inspection report for every batch.
Die building, pressing and machining for this metal housing are all in house, which keeps revision loops short and samples fast, with process data archived for repeat orders.
How it is manufactured
Manufacturing runs on a controlled process path: The shell is drawn from a blank in successive stages, annealed where the wall thins; secondary machining holds the seats, threads and faces that forming cannot produce.
The tooling record is stored against the part number, so reorders match the samples you already approved.
Materials and finishing
The standard stock list carries SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with carbon steel or stainless specified on the drawing for this metal housing.
The finish is chosen for the environment the part sees: electrophoresis, powder coating, anodising and zinc / nickel plating. The agreed finish for this metal housing travels with the part number on every reorder.
The approved sample governs later runs, so material and finish stay consistent between shipments.
Quality control
The factory operates with ISO 9001 certification: certificates verify each incoming batch of material, first-article geometry is confirmed on the CMM, and production batches are inspected on a 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. Tests for torque, leakage or pressure can be arranged when the service demands them, and the batch file carries the results.
Applications
You will find this metal housing inside vehicle and under-bonnet assemblies for OEM and Tier-1 customers.
One part number for this metal housing frequently serves several assemblies, so the finish is chosen to cover the harshest of them, and the die does not have to change.
Specifications
| Item | Wiper Motor Housing 2 |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – unusual walls, threads or tolerances are feasibility-checked first; 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 ownership is confirmed on the quotation. |
| Samples | Samples are issued for approval before the run, 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 | 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 | CIF or DDP, with FOB available, T/T or L/C, with D/P accepted on repeat business; repeat orders reuse the approved first article. |
