Aunov Tech manufactures the Deep drawn enclosure in stainless steel on a single production floor. Once installed, the drawn housing shields the assembly from dust, moisture and handling while locating it in place. The same floor forms, machines and inspects the part, so the approved sample defines every later batch without a second supplier involved.
Product overview
This metal enclosure is defined by, the draw ratio, corner radii and the faces that must stay flat, re-checked whenever the drawing is revised.
Forming, machining and finishing for this metal enclosure happen on one site, which keeps the sample loop inside our own schedule, and the approved sample is kept as the master.
How it is manufactured
Production follows a defined route: Blanks are drawn in stages, with interstage annealing where the wall thins; threads are single-pointed or rolled and seats bored in one setup where possible.
Every enclosure order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. First article, drawing revision and material cert travel with each enclosure batch.
Materials and surface finish
Our stock list runs to carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this metal enclosure is costed in carbon steel or stainless.
Coating and polishing are matched to the end use: polishing, plating in zinc, nickel or chrome, anodising, powder coating, electrophoresis and passivation. The agreed finish for this metal enclosure travels with the part number on every reorder.
The enclosure tooling and setup record is stored against the part number, so nothing depends on someone remembering. First article, drawing revision and material cert travel with each enclosure batch.
Quality control
The factory operates with ISO 9001 certification: stock arrivals are checked against mill certificates, first-article geometry is confirmed on the CMM, and production batches are inspected on a sampling plan. Seal face finish and cavity depth are measured on the enclosure first article. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the batch file carries the results.
Where the part is used
Typical installation of the metal enclosure is in industrial equipment and general assembly work for customers who buy to drawing.
One part number for this metal enclosure frequently serves several assemblies, so one tooling set serves every position, and the same first article applies throughout.
Specifications
| Item | Deep drawn enclosure |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – samples are reverse-measured into a controlled drawing; the approved drawing is kept as the controlled master. |
| 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 | Sample and first article are the same discipline here: measured, reported, then approved. |
| Materials | Stock covers carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass; special grades are sourced to the drawing when volumes justify. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; alternatives quoted with the quotation, samples approved in writing. |
| Processing | Progressive drawing through several stages, annealed between draws, then trim and pierce; every stage is logged against your part number. |
| Equipment | 5-250 T mechanical presses, 250-500 T hydraulic presses and annealing furnaces in line; secondary ops run on CNC turning centres, inspection on the CMM. |
| Tolerance | +/-0.05 mm to +/-0.1 mm across the part, wall thickness held to print; finer bands confirmed from capability data before quoting. |
| Delivery terms | Order ships FOB unless you prefer DDP; payment by T/T or L/C, freight quoted to destination. |
