Aunov Tech manufactures the Deep Drawn Copper Oxygen Chamber in copper on a single production floor. In duty, the deep drawn part carries the formed geometry the assembly needs at volume. Die work, machining and CMM inspection are all in-house, keeping first-article quality through scheduled runs under one roof.
Product overview
For this copper component, the drawing centres on, the draw ratio, corner radii and the faces that must stay flat, each measured at first article and gauged on production batches.
The whole route from die to finished copper component stays in house, so feasibility questions are answered on the shop floor, and the same die can be re-cut from the original data.
How it is manufactured
Production follows a defined route: The drawn envelope is produced in stages with anneals between them; secondary machining holds the seats, threads and faces that forming cannot produce.
Repeat black frame bracket orders are measured against the approved sample, so neither material nor finish drifts between lots. The signed black frame bracket sample remains the reference and is kept with the job file.
Materials and finishing
Everything is drawn from a fixed stock list: carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper with this copper component costed in T2 copper.
The finish is chosen for the duty it will see: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. The choice is recorded on the drawing for this copper component, so the decision never has to be made twice.
Repeat black frame bracket orders are measured against the approved sample, so neither material nor finish drifts between lots. First article, drawing revision and material cert travel with each black frame bracket batch.
Quality control
Production runs under an ISO 9001 certified quality system: mill certificates cover every delivery of stock, the CMM measures the first article dimension by dimension, and production batches are inspected on a sampling plan. For the black frame bracket, first articles are CMM measured and threads are gauged to class. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, with certificates included in the shipment file.
Where the part is used
You will find this copper component inside industrial equipment and general assembly work for OEM and Tier-1 customers.
This copper component is supplied to several positions in the same machine, so the finish is chosen to cover the harshest of them, and cost per piece stays at the volume tier.
Customization and options
Frequently varied options
What customers usually vary on this copper component: material grade, wall band, flange shape, thread size and finish for the working environment, and whether orders run as prototypes, pilot lots or scheduled batches.
Options for this copper component already covered by the die are shown on the quote, so you can see which options are free and which need new tooling. The black frame bracket quote lists quantities with the corresponding price breaks.
Specifications
| Item | Deep Drawn Copper Oxygen Chamber |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – samples are reverse-measured into a controlled drawing; changes are priced before they are made. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so tooling lead time stays under our control, and ownership is confirmed on the quotation. |
| Samples | Samples are produced on the production tooling, so what you approve is what you get. |
| Materials | T2 copper strip for conductive parts, with brass or nickel under-plating where solderability is specified. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; alternatives quoted with the quotation, samples approved in writing. |
| Processing | Stamping and forming in a progressive die with minimal secondary work; batch records are filed so a repeat order starts from approved data. |
| Equipment | Mechanical presses 5-250 T with progressive dies, with in-house toolmaking to keep dies and fixtures maintained. |
| Tolerance | +/-0.03 mm on pierced holes, +/-0.1 mm on formed sections; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | CIF or DDP, with FOB available, T/T with deposit and L/C for larger runs; repeat orders reuse the approved first article. |
Packaging and delivery
Packaging protects the finished surfaces of this copper component: interleaving, individual bags or trays are chosen by finish type, in sealed export cartons, palletised and marked as you direct.
