Aunov Tech builds this Wiper motor stamping parts in stainless steel, from coil or bar through to the finished surfaces. Once installed, the wiper motor housing drives the link and blade assembly through a geared output shaft. The same floor forms, machines and inspects the part, so the approved sample defines every later batch on one production route.
Product overview
The drawing for this metal component fixes, wall thinning, concentricity and the finished mating faces, checked by CMM at first article and by gauge in production.
The whole route from die to finished metal component stays in house, so a drawing change is absorbed in one step, and the same die can be re-cut from the original data.
How it is manufactured
Production of this metal component is locked to one route: Progressive dies blank, form and pierce from coil in one pass; strip utilisation is planned so the material cost stays predictable.
The tooling record is stored against the part number, and that record is what every reorder is built from.
Materials and finishing
The standard stock list carries cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and this metal component is costed in carbon steel or stainless.
Because the part faces weather and wash cycles, the coating is chosen for durability: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. The choice is recorded on the drawing for this metal component, so the decision never has to be made twice.
Every batch is checked against the approved sample, so nothing changes silently between orders.
Quality control
Quality management is certified to ISO 9001: certificates verify each incoming batch of material, 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. Tests for torque, leakage or pressure can be arranged when the service demands them, and the batch file carries the results.
Applications
The metal component is specified into automotive assemblies and under-hood equipment for OEM and Tier-1 customers.
Drawings for this metal component are adapted across programmes, so the finish is chosen to cover the harshest of them, and the die does not have to change.
Specifications
| Item | Wiper motor stamping parts |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – DFM notes are returned before any tooling is cut; the approved drawing is kept as the controlled master. |
| Tooling | Progressive and drawing dies are designed and built in house, so a die can be re-cut against the approved drawing, and ownership is confirmed on the quotation. |
| Samples | Prototype and pre-production samples are provided against the drawing, so the approved first article becomes the gauge reference, 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 or nickel plating for corrosion, plus powder coating or electrophoresis on housings; laser etching on request. |
| Processing | Blanking and progressive forming on automated lines, then secondary tapping, bending and finishing. |
| Equipment | Progressive presses 25-200 T, decoilers and coil feeders, vibratory finishing lines and a full in-house toolroom. |
| Tolerance | +/-0.05 mm on controlled dimensions and +/-0.1 mm on general features; capability studies supplied on request. |
| Delivery terms | FOB Ningbo or Shanghai, T/T or L/C, with D/P accepted on repeat business; call-off schedules are supported. |
