Produced in stainless steel by Aunov Tech, the Stainless Steel Compression Union Adapter is formed and machined on the same floor. In service, the deep drawn part replaces a machined-from-solid body with a lighter, faster drawn shell. Forming, machining and inspection share one floor, so the approved sample defines every later batch with no third party in the loop.
Product overview
This stainless steel adapter is defined by, wall thinning, concentricity and the finished mating faces, checked by CMM at first article and by gauge in production.
Toolroom, presses and machining centres used on this stainless steel adapter operate on the same site, so a change of wall or hole does not restart the programme, and the approved sample is kept as the master.
How it is manufactured
Production follows a defined route: The shell starts as coil or blank and is drawn through single and progressive dies; threads are single-pointed or rolled and seats bored in one setup where possible.
Process settings are archived with the part number, and that record is what every reorder is built from.
Materials and finishing
Materials kept on the floor cover cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and this stainless steel adapter runs in 304 / 316 stainless steel.
The finish is chosen for the duty it will see: plating, anodising, powder coating, electrophoresis and passivation. It is fixed on the drawing for this stainless steel adapter, so repeat orders never reopen the question.
Each shipment is verified against the master sample, so the colour and grain of the finish stay stable.
Quality control
The factory operates with ISO 9001 certification: certificates verify each incoming batch of material, a full CMM report approves the first article, and later batches follow the sampling plan agreed at approval. The sleeve union fittings, first article goes on the CMM, with threads gauged to class. Functional testing – torque, leak or pressure – can be written into the plan, and the inspection report ships with each batch.
Applications
You will find this stainless steel adapter inside industrial equipment and general assembly work under schedules that run for years at a time.
The same stainless steel adapter is used across several platforms, so the specification is set by the toughest of them, and the die does not have to change.
Customization and options
Frequently varied options
What customers usually vary on this stainless steel adapter: material grade, wall band, flange shape, thread size and finish for the working environment, and whether the programme starts as a sample or a full release.
The quotation for this stainless steel adapter is explicit about what the die already covers, so there are no surprise tooling charges after approval. The same split appears on every sleeve union fittings, reorder.
Specifications
| Item | Stainless Steel Compression Union Adapter |
|---|---|
| Brand | AUNOV |
| Designing | The quotation follows your print, not a catalogue – unusual walls, threads or tolerances are checked for feasibility first. |
| Tooling | Progressive and drawing dies are designed and built in house, so tooling lead time stays under our control, and maintenance is tracked against the part number. |
| Samples | Samples are issued for approval before the run, and production starts only after written sign-off. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass are held on site; grade and temper are confirmed in writing before tooling. |
| Surface finish | Surface treatment matched to the duty: plating, coating or polishing; alternatives quoted with the quotation, samples approved in writing. |
| Processing | CNC turning with milling and drilling in as few setups as the geometry allows; batch records are filed so a repeat order starts from approved data. |
| Equipment | Bar-fed CNC turning centres plus 3- and 4-axis machining centres; secondary ops run on CNC turning centres, inspection on the CMM. |
| Tolerance | +/-0.01 mm on machined faces, +/-0.05 mm on formed details; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, payment by T/T, L/C at sight or D/P; each volume tier carries its own quoted price. |
Packaging and delivery
The finish on this stainless steel adapter dictates how it is packed: interleaves, polybags or formed trays are selected according to the coating, in sealed cartons on export pallets, with documents issued to your instructions.
