Produced in aluminum by Aunov Tech, the Black Anodized Aluminum Threaded Tube Sleeve is formed and machined on the same floor. In service, the CNC machined part delivers the precise turned or milled geometry the assembly mounts to. Forming, machining and inspection share one floor, so first-article dimensions hold through volume batches without re-quoting the job elsewhere.
Product overview
The drawing for this aluminium tube fixes, wall thinning, concentricity and the finished mating faces, audited against the approved sample at each production release.
Die building, pressing and machining for this aluminium tube are all in house, which keeps the sample loop inside our own schedule, and the approved sample is kept as the master.
Production route
Production of this aluminium tube is locked to one route: Coil is blanked and then drawn down in successive stages; the finishing operations hold the concentricity the drawing calls for.
The slotted split bushing manufacturing record is archived together with the drawing revision that produced it. The approved slotted split bushing 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 and the grade agreed for this aluminium tube is aluminium.
Coating and polishing are matched to the end use: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. Once approved, the finish for this aluminium tube is fixed and does not get re-decided.
Route cards follow each slotted split bushing batch through the shop, so the next run starts from the data that already worked. Deviations on the slotted split bushing are reported before shipment rather than found on your assembly line.
Quality control and inspection
Production runs under an ISO 9001 certified quality system: incoming material is verified against mill certificates, first articles are measured on a CMM, and run inspections follow an agreed sampling plan. First article of the slotted split bushing: CMM data on diameters, thread class confirmed by gauge. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the report is packed with the shipment.
Where the part is used
The aluminium tube is fitted into industrial and appliance assemblies in both OEM and aftermarket supply.
A single design of this aluminium tube is often reused across a product family, so the tightest tolerance in the family sets the spec, and approvals carry across programmes.
Customization and options
Frequently varied options
The parts of the print for this aluminium tube that get adjusted: material grade, coating, wall bands, flange form and end closure, and how the order is released – sample, pilot run or scheduled call-off.
The quotation for this aluminium tube marks what the existing tooling can do, so the boundary between free and chargeable changes is explicit. The quotation for the slotted split bushing states both quantities and price breaks.
Specifications
| Item | Black Anodized Aluminum Threaded Tube Sleeve |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – a manufacturability review comes back with the quotation; the approved drawing is kept as the controlled master. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so a die can be re-cut against the approved drawing, and first-article timing is measured from the tooling start date. |
| Samples | Sample approval is documented: dimensions, finish and material recorded for later comparison. |
| Materials | Stock covers carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass; material substitutes are proposed only with your written approval. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; finish thickness and adhesion checked on the first article. |
| Processing | Bar-fed turning with milled features completed in the same clamping; every stage is logged against your part number. |
| Equipment | 12 CNC turning centres with automatic bar feeders, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.01 mm on machined faces, +/-0.05 mm on formed details; finer bands confirmed from capability data before quoting. |
| Delivery terms | Freight, Incoterm and payment term are confirmed on the order: FOB, CIF or DDP, T/T or L/C. |
Packing and shipment
Finish comes first when packing this aluminium tube: each coating gets its own packing – interleaves, bags or trays, in sealed export cartons, palletised and marked as you direct.
