Aunov Tech builds this Power window regulator motor casing in stainless steel, from coil or bar through to the finished surfaces. On the product, the window lift motor housing locates the gear train while shielding the windings from dust. Drawing, cutting and measurement sit on one floor, keeping first-article quality through scheduled runs without re-quoting the job elsewhere.
Product overview
The specification of this metal casing turns on, the forming route, the tolerance band and the sealing faces, checked by CMM at first article and by gauge in production.
Tooling and finishing for this metal casing run under one roof, which keeps the sample loop inside our own schedule, and the approved sample is kept as the master.
From coil to finished part
Manufacturing runs on a controlled process path: The drawn envelope is produced in stages with anneals between them; the finishing operations hold the concentricity the drawing calls for.
Batch records are filed against the part number, and that record is what every reorder is built from.
Materials and finishing
Everything is drawn from a fixed stock list: cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and this metal casing is costed in carbon steel or stainless.
The surface treatment is picked to match the service conditions: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. It is fixed on the drawing for this metal casing, so repeat orders never reopen the question.
Every batch is checked against the approved sample, and grade changes have to be agreed in writing first.
Quality control
Production runs under an ISO 9001 certified quality system: stock arrivals are checked against mill certificates, the CMM measures the first article dimension by dimension, and production batches are inspected on a sampling plan. At window lift motor housing level, gear-bore alignment is checked at first article on a CMM, and noise-critical seats are gauged each run. Where the application asks for it, torque, leak or pressure testing is added to the plan, with certificates included in the shipment file.
Applications
The metal casing is specified into industrial machinery and equipment assemblies across automotive, appliance and industrial programmes.
This metal casing is supplied to several positions in the same machine, so wall bands and finishes are selected to cover the widest duty, and cost per piece stays at the volume tier.
Specifications
| Item | Power window regulator motor casing |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – samples are reverse-measured into a controlled drawing; the agreed version governs every later batch. |
| Tooling | Progressive and drawing dies are designed and built in house, so the die charge appears as its own quotation line, and maintenance is tracked against the part number. |
| Samples | Samples are issued for approval before the run, so the sample is retained as the master, and later batches are gauged back to the signed sample. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this casing. |
| Surface finish | Polishing, zinc / nickel / chrome plating, anodising, powder coating, electrophoresis and passivation. |
| 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 | +/-0.01 mm on machined faces and +/-0.05 mm on formed details; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, T/T with deposit and L/C for larger runs; repeat orders reuse the approved first article. |
