Produced in stainless steel by Aunov Tech, the Power window regulator motor can is formed and machined on the same floor. In operation, the window lift motor housing locates the gear train while shielding the windings from dust. Die work, machining and CMM inspection are all in-house, and a design change is re-sampled in one place without a second supplier involved.
Product overview
For this metal can, the drawing centres on, material grade, wall uniformity and thread position, re-checked whenever the drawing is revised.
The press shop and machine shop that make this metal can share one floor, so a drawing change is absorbed in one step, with process data archived for repeat orders.
How it is manufactured
This is how the metal can is built: Drawing converts a flat blank into the finished envelope in one controlled sequence; secondary machining holds the seats, threads and faces that forming cannot produce.
Process settings are archived with the part number, so a repeat order starts from the same approved data.
Materials and surface finish
Working stock covers carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this metal can is costed in carbon steel or stainless.
Coating and polishing are matched to the end use: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. The choice is recorded on the drawing for this metal can, so the decision never has to be made twice.
Later runs are measured back to the first article, and grade changes have to be agreed in writing first.
Quality control
An ISO 9001 certified system governs production: certificates verify each incoming batch of material, the first article is CMM-measured against the print, and run inspections follow an agreed sampling plan. For the window lift motor housing, gear-bore alignment is checked at first article on a CMM, and noise-critical seats are gauged each run. Tests for torque, leakage or pressure can be arranged when the service demands them, and results travel with the batch paperwork.
Typical applications
This metal can normally works inside industrial and appliance assemblies under schedules that run for years at a time.
One part number for this metal can frequently serves several assemblies, so a single grade and coating can cover each application, and no re-tooling is needed.
Specifications
| Item | Power window regulator motor can |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – unusual walls, threads or tolerances are feasibility-checked first; the same drawing is used for every repeat order. |
| Tooling | Progressive and drawing dies are designed and built in house, so tooling lead time stays under our control, and the charge is refundable against agreed volumes. |
| Samples | Pre-production samples come with a full inspection report, so the approved first article becomes the gauge reference, 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 | Phosphating for coating adhesion, then powder coating, e-coating or zinc plating; chrome and nickel for visible faces. |
| 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 | +/-0.01 mm on machined faces and +/-0.05 mm on formed details; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | CIF or DDP, with FOB available, payment by T/T, L/C at sight or D/P; repeat orders reuse the approved first article. |
