Aunov Tech manufactures the Finned Aluminum CNC Machined Heat Sink Fitting in aluminum on a single production floor. In the assembly, the CNC machined part carries the controlled features that forming alone cannot hold. Forming, machining and inspection share one floor, and a design change is re-sampled in one place without re-quoting the job elsewhere.
Product overview
What defines this aluminium fitting is, wall thinning, concentricity and the finished mating faces, re-checked whenever the drawing is revised.
Toolroom, presses and machining centres used on this aluminium fitting operate on the same site, so the route from print to sample stays short, with the tooling history retained in house.
How it is manufactured
Manufacturing runs on a controlled process path: Machining starts from bar or plate and runs on CNC centres; in-process gauging runs alongside the machines on longer batches.
Each shipment is traceable to the signed first article, so a repeat order starts from the same approved data.
Materials and finishing
Standard stock includes cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze with aluminium specified on the drawing for this aluminium fitting.
The finish is chosen for the duty it will see: electrophoresis, powder coating, anodising and zinc / nickel plating. The choice is recorded on the drawing for this aluminium fitting, so the decision never has to be made twice.
The tapered reducer sleeve manufacturing record is archived together with the drawing revision that produced it. Process settings for the tapered reducer sleeve are archived, so later runs can be compared with the one you approved.
Quality control and inspection
Production runs under an ISO 9001 certified quality system: mill certificates cover every delivery of stock, first-article geometry is confirmed on the CMM, and routine sampling keeps batches aligned with the first article. The tapered reducer sleeve first article is measured on the CMM and thread gauges confirm class. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the batch file carries the results.
Applications
The aluminium fitting is specified into industrial equipment and general assembly work across automotive, appliance and industrial programmes.
A single design of this aluminium fitting is often reused across a product family, so one approved version covers the whole range, and the drawing stays common.
Customization and options
Options changed most often
Points customers normally tailor on this aluminium fitting: wall thickness bands, flange geometry, thread call-outs and the surface finish, and whether the programme starts as a sample or a full release.
The quote for this aluminium fitting separates tooled options from new work, so the effect of a revision on price is clear up front. For the tapered reducer sleeve, tooling terms live in the quote – nothing is left implied.
Specifications
| Item | Finned Aluminum CNC Machined Heat Sink Fitting |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – unusual walls, threads or tolerances are feasibility-checked first; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so a die can be re-cut against the approved drawing, and the charge is refundable against agreed volumes. |
| Samples | Samples are produced on the production tooling, so what you approve is what you get. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass are held on site; material substitutes are proposed only with your written approval. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; the finish is inspected with the dimensional report on the first article. |
| Processing | CNC turning with milling and drilling in as few setups as the geometry allows; every stage is logged against your part number. |
| Equipment | CNC turning centres with bar feeders and 3-/4-axis machining centres, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.01 mm on turned and milled features; capability is checked on the first article before the run continues. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, payment by T/T or L/C, quoted in USD or EUR; price breaks tie to annual volume. |
Packing and shipment
The packing method protects the surfaces of this aluminium fitting: each coating gets its own packing – interleaves, bags or trays, in sealed cartons on export pallets; shipping documents and carton marks follow your instructions.
