Aunov Tech builds this Deep Drawn Aluminum Smoke Detector Cover in aluminum, from coil or bar through to the finished surfaces. In the assembly, the drawn housing encloses the sensitive internals and carries the mounting interface. The same floor forms, machines and inspects the part, so first-article dimensions hold through volume batches without a second supplier involved.
Product overview
The critical features of this aluminium cover are, draw depth, wall band and the surfaces that forming cannot hold, all held to the drawing and verified at first article.
Die work and machining for this aluminium cover sit on the same floor, so a change of wall or hole does not restart the programme, with the tooling history retained in house.
How the part is produced
Production of this aluminium cover is locked to one route: The drawn envelope is produced in stages with anneals between them; the finishing operations hold the concentricity the drawing calls for.
The white perforated smoke is judged by the dimension nobody checks until a failure – fit, seal or concentricity. Tolerances that matter are confirmed with capability data before the white perforated smoke is quoted.
Materials and finishing
Base materials in stock: cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze with aluminium specified on the drawing for this aluminium cover.
Finish selection follows the working environment: polishing, zinc / nickel / chrome plating, anodising or powder coating. Once approved, the finish for this aluminium cover is fixed and does not get re-decided.
The white perforated smoke manufacturing record is archived together with the drawing revision that produced it. Deviations on the white perforated smoke are reported before shipment rather than found on your assembly line.
Quality control
Quality management is certified to ISO 9001: mill certificates cover every delivery of stock, the first article is CMM-measured against the print, and production batches are inspected on a sampling plan. First article of the white perforated smoke includes cavity depth and seal face finish data. Torque, leak and pressure tests are available where the assembly needs them, with certificates included in the shipment file.
Typical applications
The aluminium cover is specified into industrial equipment and general assembly work under schedules that run for years at a time.
This aluminium cover is supplied to several positions in the same machine, so one approved version covers the whole range, and the same first article applies throughout.
Customization and options
What customers usually vary
The parts of the print for this aluminium cover that get adjusted: wall thickness bands, flange geometry, thread call-outs and the surface finish, and whether the first order is a prototype, a pilot lot or a production release.
Quotes for this aluminium cover show which options the current die already supports, so new tooling is only quoted where it is genuinely required. The same split appears on every white perforated smoke reorder.
Specifications
| Item | Deep Drawn Aluminum Smoke Detector Cover |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – DFM notes are returned before any tooling is cut; changes are priced before they are made. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so die cost stays transparent, and the die remains dedicated to your part. |
| Samples | Samples are issued for approval before the run, so the approved first article becomes the gauge reference, and the signed sample is kept for future reorders. |
| Materials | Stock runs to carbon steel, 304 / 316 stainless, aluminium and brass; grade and temper are confirmed in writing before tooling. |
| Surface finish | Surface treatment matched to the duty: plating, coating or polishing; masking and laser marking available where needed. |
| Processing | Multi-stage deep drawing with interstage annealing, trimmed and pierced in following dies; first articles verify the whole flow before the run is released. |
| Equipment | Mechanical presses from 5 to 250 T and hydraulic presses 250-500 T, with in-line annealing furnaces, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.03 mm on turned secondary features, +/-0.1 mm on as-drawn walls; dimensional reports accompany the first article. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, T/T with deposit and L/C for larger runs; price breaks tie to annual volume. |
Packaging and delivery
This aluminium cover is packed to protect the finish: each coating gets its own packing – interleaves, bags or trays, in sealed cartons on export pallets, documented and marked to your instruction.
