This Precision sheet metal deep drawn power window switch housing is an Aunov Tech production part in stainless steel, quoted and built to customer print. In the assembly, the drawn housing encloses the sensitive internals and carries the mounting interface. The same floor forms, machines and inspects the part, which keeps tolerances consistent from sample to volume without a second supplier involved.
Product overview
The drawing for this metal housing fixes, the formed envelope, flatness and hole location, re-checked whenever the drawing is revised.
Die building, pressing and machining for this metal housing are all in house, so a drawing change is absorbed in one step, and the approved sample is kept as the master.
How it is manufactured
Production follows a defined route: The shell is drawn from a blank in successive stages, annealed where the wall thins; threads are single-pointed or rolled and seats bored in one setup where possible.
Production batches of the sheet metal power are gauged back to the signed first article, not to a memory of it. Mill certificates are filed per heat, so sheet metal power traceability survives a change of material batch.
Materials and finishing
Materials kept on the floor cover SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and the grade agreed for this metal housing is carbon steel or stainless.
The finish is chosen for the duty it will see: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. The finish on this metal housing is locked to the drawing revision, so later orders match.
Production is compared with the approved sample every run, so neither material nor finish drifts between lots.
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 every production run is inspected against the first-article report. Seal face finish and cavity depth are measured on the sheet metal power first article. Torque, leak and pressure tests are available where the assembly needs them, and the inspection report ships with each batch.
Applications
The metal housing is specified into industrial and appliance assemblies for customers who own the drawing and the tooling.
The same metal housing is often run in more than one assembly, so the specification is set by the toughest of them, and the drawing stays common.
Specifications
| Item | Precision sheet metal deep drawn power window switch housing |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – DFM notes are returned before any tooling is cut; the agreed version governs every later batch. |
| Tooling | Tooling is built and held under your part number, so no tooling step is outsourced, and the charge is refundable against agreed volumes. |
| Samples | Samples are issued for approval before the run, so the part is proven before it is made in volume, and mass production is gated on that approval. |
| Materials | Stock runs to carbon steel, 304 / 316 stainless, aluminium and brass; material substitutes are proposed only with your written approval. |
| Surface finish | Natural, plated or coated – the print decides, and the agreed finish is logged; finish thickness and adhesion checked on the first article. |
| Processing | Multi-stage deep drawing with interstage annealing, trimmed and pierced in following dies; batch records are filed so a repeat order starts from approved data. |
| Equipment | Mechanical presses 5-250 T plus 250-500 T hydraulics, with in-line annealing, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.03 mm on turned secondary features, +/-0.1 mm on as-drawn walls; dimensional reports accompany the first article. |
| Delivery terms | Delivery is quoted to your location: FOB, CIF or DDP, by sea or air as you prefer. |
