This Wiper motor cup is an Aunov Tech production part in stainless steel, quoted and built to customer print. On the product, the wiper motor housing protects the motor windings while the output shaft takes the wipe load. Drawing, cutting and measurement sit on one floor, so the approved sample defines every later batch under one roof.
Product overview
The specification of this metal component turns on, material grade, wall uniformity and thread position, recorded on the inspection report for every batch.
Die building, pressing and machining for this metal component are all in house, which keeps revision loops short and samples fast, and the approved sample is kept as the master.
How it is manufactured
The route for this metal component is fixed and repeatable: The drawn envelope is produced in stages with anneals between them; the part is annealed between stages so the wall thins evenly.
Route cards follow every order through the shop, and that record is what every reorder is built from.
Materials and finishing
Materials kept on the floor cover SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this metal component runs in carbon steel or stainless.
Coating selection follows the duty – indoor, outdoor or under-hood: electrophoresis, powder coating, anodising and zinc / nickel plating. The choice is recorded on the drawing for this metal component, so the decision never has to be made twice.
Production batches are gauged to the signed first article, so nothing changes silently between orders.
Quality control and inspection
The plant is ISO 9001 certified: stock arrivals are checked against mill certificates, the CMM measures the first article dimension by dimension, and every production run is inspected against the first-article report. For the wiper motor housing, 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
This metal component normally works inside automotive assemblies and under-hood equipment for customers who buy to drawing.
This metal component is supplied to several positions in the same machine, so a single grade and coating can cover each application, and cost per piece stays at the volume tier.
Specifications
| Item | Wiper motor cup |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – samples are reverse-measured into a controlled drawing; the same drawing is used for every repeat order. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so the die charge appears as its own quotation line, and first-article timing is measured from the tooling start date. |
| Samples | Samples are issued for approval before the run, so any deviation is corrected at sample stage, and the signed sample is kept for future reorders. |
| Materials | Stock covers carbon steel, 304 / 316 stainless, aluminium and brass; the final grade is fixed with the drawing review. |
| Surface finish | Zinc or nickel plating for corrosion, plus powder coating or electrophoresis on housings; laser etching on request. |
| Processing | Blanking, multi-stage deep drawing with interstage annealing, trimming and piercing, coining, then finishing. |
| Equipment | 5-250 T mechanical presses and 250-500 T hydraulic presses, in-line annealing furnace, CNC turning for secondary work. |
| Tolerance | +/-0.03 mm on machined features, +/-0.1 mm on formed ones, with first-article inspection report. |
| 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. |
