This Deep Draw Wiper Motor Housing is an Aunov Tech production part in stainless steel, quoted and built to customer print. In the assembly, the wiper motor housing drives the link and blade assembly through a geared output shaft. Forming, machining and inspection share one floor, which keeps tolerances consistent from sample to volume without handing the part to another vendor.
Product overview
What matters most on this metal housing is, draw depth, wall band and the surfaces that forming cannot hold, audited against the approved sample at each production release.
The press shop and machine shop that make this metal housing share one floor, which keeps revision loops short and samples fast, and the same die can be re-cut from the original data.
Production route
This is how the metal housing is built: The drawn envelope is produced in stages with anneals between them; wall thickness is checked at the thinnest section after forming.
Process settings are archived with the part number, so nothing depends on the operator remembering.
Materials and finishing
Base materials in stock: 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.
Because the part faces weather and wash cycles, the coating is chosen for durability: plating, anodising, powder coating, electrophoresis and passivation. The finish on this metal housing is locked to the drawing revision, so later orders match.
Later runs are measured back to the first article, and material certificates are kept per batch.
Quality control and inspection
An ISO 9001 certified system governs production: incoming material is verified against mill certificates, first-article geometry is confirmed on the CMM, and every production run is inspected against the first-article report. 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. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the inspection report ships with each batch.
Applications
The metal housing is fitted into automotive assemblies and under-hood equipment for customers who buy to drawing.
One part number for this metal housing frequently serves several assemblies, so the finish is chosen to cover the harshest of them, and the same first article applies throughout.
Specifications
| Item | Deep Draw Wiper Motor Housing |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – a manufacturability review comes back with the quotation; changes are priced before they are made. |
| Tooling | Die design and toolmaking stay in house, so tooling lead time stays under our control, and ownership is confirmed on the quotation. |
| Samples | Sample parts are measured and reported before submission, 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 housing. |
| 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 | 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 Ningbo or Shanghai, payment by T/T, L/C at sight or D/P; each volume tier carries its own quoted price. |
