Aunov Tech builds this Deep Drawn Stainless Steel Parts Light Cover Metal Spinning Fabrication in stainless steel, from coil or bar through to the finished surfaces. On the product, the CNC machined part carries the controlled features that forming alone cannot hold. One production floor covers forming, finishing and inspection, so repeat orders stay aligned with the approved sample without a second supplier involved.
Product overview
The critical features of this stainless steel cover are, the forming route, the tolerance band and the sealing faces, audited against the approved sample at each production release.
Die work and machining for this stainless steel cover sit on the same floor, which keeps the sample loop inside our own schedule, with process data archived for repeat orders.
How it is manufactured
Every stainless steel cover follows the same routed path: Drawing runs from flat blank to finished envelope in one controlled sequence; piercing and trimming are done in the same die line.
Repeat eyelet orders are measured against the approved sample, so neither material nor finish drifts between lots. The approved eyelet sample governs later runs, and any grade change is agreed in writing first.
Materials and finishing
Our stock list runs to cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze with 304 / 316 stainless steel specified on the drawing for this stainless steel cover.
Finish selection follows the working environment: electrophoresis, powder coating, anodising and zinc / nickel plating. It is fixed on the drawing for this stainless steel cover, so repeat orders never reopen the question.
Repeat eyelet orders are measured against the approved sample, so neither material nor finish drifts between lots. Mill certificates are filed per heat, so eyelet traceability survives a change of material batch.
Quality control
An ISO 9001 certified system governs production: incoming material is verified against mill certificates, a full CMM report approves the first article, and production batches are inspected on a sampling plan. CMM first-article measurement of the eyelet covers diameters and gauges thread class. Torque, leak and pressure tests are available where the assembly needs them, with certificates included in the shipment file.
Applications
You will find this stainless steel cover inside LED and lighting assemblies for customers who buy to drawing.
One part number for this stainless steel cover frequently serves several assemblies, so one tooling set serves every position, and approvals carry across programmes.
Customization and options
Options changed most often
Points customers normally tailor on this stainless steel cover: grade and finish for the environment, wall thickness bands, flange and rim forms, threads, bosses and closed ends, and whether the first order is a prototype, a pilot lot or a production release.
The quote for this stainless steel cover separates tooled options from new work, so you can see which options are free and which need new tooling. The eyelet stays as approved until a written revision says otherwise.
Specifications
| Item | Deep Drawn Stainless Steel Parts Light Cover Metal Spinning Fabrication |
|---|---|
| Brand | AUNOV |
| Designing | Design intent is read from the print, and any conflict in the drawing is raised before quoting. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so no tooling step is outsourced, and maintenance is tracked against the part number. |
| Samples | Sample parts are measured and reported before submission, so the sample is retained as the master, and production starts only after your written sign-off. |
| Materials | Materials held include carbon steel, 304 / 316 stainless, aluminium and brass; material substitutes are proposed only with your written approval. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; the agreed finish travels with the part number. |
| Processing | Deep drawing from coil or blank, with in-process annealing so walls thin evenly; every stage is logged against your part number. |
| Equipment | 5-250 T mechanical presses, 250-500 T hydraulic presses and annealing furnaces in line, with in-house toolmaking to keep dies and fixtures maintained. |
| Tolerance | +/-0.05 mm on flange and rim dimensions, wall controlled by the draw; critical dimensions carry CMM data with the shipment. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, T/T or L/C, with D/P accepted on repeat business; repeat orders reuse the approved first article. |
Packaging and delivery
Packing for this stainless steel cover is chosen around the coating: the coating decides whether parts are interleaved, bagged or tray-packed, in sealed cartons on export pallets, documented and marked to your instruction.
