The Deep Drawn and Hydroformed Aluminum Electrical Cover is produced by Aunov Tech from aluminum, formed and finished under one roof. In duty, the drawn housing provides a closed, seam-free body the customer builds into. One production floor covers forming, finishing and inspection, so first-article dimensions hold through volume batches without a second supplier involved.
Product overview
The specification of this aluminium cover turns on, draw depth, wall band and the surfaces that forming cannot hold, checked by CMM at first article and by gauge in production.
Forming, machining and finishing for this aluminium cover happen on one site, so revisions do not wait on outside suppliers, and the approved sample is kept as the master.
From coil to finished part
This is how the aluminium cover is built: A welded preform is expanded in the hydroforming press; ends are trimmed and pierced, then the part is annealed and finished.
Production batches of the black electronic frame are gauged back to the signed first article, not to a memory of it. Any change to the black electronic frame drawing is re-approved and re-verified before production continues.
Materials and finishing
Working stock covers SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this aluminium cover is costed in aluminium.
Coating and polishing are matched to the end use: electrophoresis, powder coating, anodising and zinc / nickel plating. Once approved, the finish for this aluminium cover is fixed and does not get re-decided.
The black electronic frame manufacturing record is archived together with the drawing revision that produced it. Process settings for the black electronic frame are archived, so later runs can be compared with the one you approved.
Quality control
Production runs under an ISO 9001 certified quality system: mill certificates cover every delivery of stock, first articles are measured on a CMM, and every production run is inspected against the first-article report. For the black electronic frame, cavity depth and seal face finish are checked at first article. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the inspection report ships with each batch.
Applications
This aluminium cover normally works inside industrial machinery and equipment assemblies in both OEM and aftermarket supply.
The same aluminium cover is used across several platforms, so one tooling set serves every position, without a second tooling round.
Customization and options
Frequently varied options
Points customers normally tailor on this aluminium cover: material grade, coating, wall bands, flange form and end closure, and the batch pattern – prototype, pilot lot or scheduled production.
The quotation for this aluminium cover is explicit about what the die already covers, so the effect of a revision on price is clear up front. Once approved, the revised black electronic frame drawing becomes the new master.
Specifications
| Item | Deep Drawn and Hydroformed Aluminum Electrical Cover |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – a manufacturability review comes back with the quotation; changes are priced before they are made. |
| 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 | Prototype and pre-production samples are provided against the drawing, so any deviation is corrected at sample stage, and later batches are gauged back to the signed sample. |
| Materials | 1050 / 3003 / 5052 / 6061 aluminium, 0.5-3.0 mm stock – temper matched to the forming depth or machining route of this cover. |
| Surface finish | Plating, coating or polishing to suit the drawing; alternatives quoted with the quotation, samples approved in writing. |
| Processing | Tube or sheet preform, hydroforming into the finished contour, trimming, then annealing and finishing. |
| Equipment | 5-250 T mechanical presses, 250-500 T hydraulic presses and annealing furnaces in line, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.05 mm on flange and rim dimensions, wall controlled by the draw; dimensional reports accompany the first article. |
| Delivery terms | Freight, Incoterm and payment term are confirmed on the order: FOB, CIF or DDP, T/T or L/C. |
Packaging and delivery
This aluminium cover is packed to protect the finish: interleaves, bags or trays are matched to the surface treatment, in sealed cartons on export pallets, with documents issued to your instructions.
