The Custom Deep Drawn Part Copper Sleeve is produced by Aunov Tech from copper, formed and finished under one roof. In duty, the deep drawn tube carries fluid or motion through a closed drawn wall. One production floor covers forming, finishing and inspection, so first-article dimensions hold through volume batches on one production route.
Product overview
The critical features of this copper sleeve are, the draw ratio, corner radii and the faces that must stay flat, recorded on the inspection report for every batch.
The press shop and machine shop that make this copper sleeve share one floor, so revisions do not wait on outside suppliers, and the same die can be re-cut from the original data.
How it is manufactured
This is how the copper sleeve is built: Blanks are drawn in stages, with interstage annealing where the wall thins; the finishing operations hold the concentricity the drawing calls for.
Batch records for the cover are filed against the part number, so process settings are reused instead of re-invented. Process settings for the cover are archived, so later runs can be compared with the one you approved.
Materials and finishing
Everything is drawn from a fixed stock list: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with T2 copper specified on the drawing for this copper sleeve.
Coating and polishing are matched to the end use: plating, anodising, powder coating, electrophoresis and passivation. The choice is recorded on the drawing for this copper sleeve, so the decision never has to be made twice.
Production batches of the cover are gauged back to the signed first article, not to a memory of it. Process settings for the cover are archived, so later runs can be compared with the one you approved.
Quality control and inspection
Quality management is certified to ISO 9001: stock arrivals are checked against mill certificates, the first article is CMM-measured against the print, and routine sampling keeps batches aligned with the first article. The cover first-article report includes wall thickness readings. Functional testing – torque, leak or pressure – can be written into the plan, and the report is packed with the shipment.
Applications
This copper sleeve is used in industrial equipment and general assembly work for OEM and Tier-1 customers.
A single design of this copper sleeve is often reused across a product family, so one approved version covers the whole range, and the same first article applies throughout.
Customization and options
What customers usually vary
Options customers tend to adapt on this copper sleeve: material and coating for the duty, wall bands, flange forms, threads and bosses, closed ends and finishes matched to the working environment, and whether the first order is a prototype, a pilot lot or a production release.
Options for this copper sleeve already covered by the die are shown on the quote, so the effect of a revision on price is clear up front. Ownership of the cover tooling is written into the quotation.
Specifications
| Item | Custom Deep Drawn Part Copper Sleeve |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – a manufacturability review comes back with the quotation; the approved drawing is kept as the controlled master. |
| Tooling | Tooling is built and held under your part number, so tooling lead time stays under our control, and first-article timing is measured from the tooling start date. |
| Samples | Prototype and pre-production samples are provided against the drawing, so the approved first article becomes the gauge reference, and mass production is gated on that approval. |
| Materials | T2 / T3 copper and H62 brass, 0.8-4.0 mm; soft tempers for deep forming, hard tempers where stiffness matters. |
| Surface finish | Plating, coating or polishing to suit the drawing; masking and laser marking available where needed. |
| Processing | Tube drawing with precision turning on critical diameters; first articles verify the whole flow before the run is released. |
| Equipment | Drawn-tube benches, in-line annealing and CNC turning, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.03 mm on machined features, +/-0.1 mm on formed ones; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | Order ships FOB unless you prefer DDP; payment by T/T or L/C, freight quoted to destination. |
Packing and shipment
Packing for this copper sleeve is chosen around the coating: interleaving, individual bags or trays are chosen by finish type, in sealed cartons on export pallets; shipping documents and carton marks follow your instructions.
