Aunov Tech manufactures the Stainless Steel Hose Barb Threaded Adapter in stainless steel on a single production floor. On the product, the CNC machined part delivers the precise turned or milled geometry the assembly mounts to. Forming, machining and inspection share one floor, which keeps tolerances consistent from sample to volume under one roof.
Product overview
The specification of this stainless steel adapter turns on, draw depth, wall band and the surfaces that forming cannot hold, each measured at first article and gauged on production batches.
The press shop and machine shop that make this stainless steel adapter share one floor, so feasibility questions are answered on the shop floor, and the approved sample is kept as the master.
How the part is produced
This is how the stainless steel adapter is built: The drawn envelope is produced in stages with anneals between them; the part is annealed between stages so the wall thins evenly.
Batch records for the stepped flanged bushing are filed against the part number, so process settings are reused instead of re-invented. The signed stepped flanged bushing sample remains the reference and is kept with the job file.
Materials and finishing
Base materials in stock: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and the grade agreed for this stainless steel adapter is 304 / 316 stainless steel.
Coating and polishing are matched to the end use: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. The finish on this stainless steel adapter is locked to the drawing revision, so later orders match.
Each stepped flanged bushing shipment is verified against the master sample before it leaves the shop. Mill certificates are filed per heat, so stepped flanged bushing traceability survives a change of material batch.
Quality control
The plant is ISO 9001 certified: stock arrivals are checked against mill certificates, the first article is CMM-measured against the print, and production batches are inspected on a sampling plan. CMM first-article measurement of the stepped flanged bushing covers diameters and gauges thread class. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and results travel with the batch paperwork.
Applications
Typical installation of the stainless steel adapter is in industrial and appliance assemblies under schedules that run for years at a time.
The same stainless steel adapter is often run in more than one assembly, so one tooling set serves every position, and the same first article applies throughout.
Options and variations
The options customers tune most
Material – carbon steel, stainless, aluminum or brass; finish – plating, anodizing or coating matched to the working environment; features – thread classes, seat finishes, milled features, cross-holes and plating or anodizing to the print; lot size – prototypes for validation, then scheduled batches against a call-off.
Every change is quoted with its tooling consequence shown, making the cost of each choice clear before you commit.
Specifications
| Item | Stainless Steel Hose Barb Threaded Adapter |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – unusual walls, threads or tolerances are feasibility-checked first; the agreed version governs every later batch. |
| Tooling | Tooling is built and held under your part number, so a die can be re-cut against the approved drawing, and ownership is confirmed on the quotation. |
| Samples | Approval is in writing, and the signed sample is kept as the reference for repeats. |
| Materials | Materials held include carbon steel, 304 / 316 stainless, aluminium and brass; grade and temper are confirmed in writing before tooling. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; the finish is inspected with the dimensional report on the first article. |
| Processing | CNC turning from bar or billet, concentricity held across operations; in-process checks sit between stages, not only at the end. |
| Equipment | CNC turning centres with bar feeders and 3-/4-axis machining centres; first articles and batch samples are checked on the CMM. |
| Tolerance | +/-0.01 mm on ground diameters, with GD&T taken from your print; dimensional reports accompany the first article. |
| Delivery terms | FOB with DDP offered for EU and US addresses; payment T/T or L/C, freight quoted to destination. |
Packaging and delivery
For this stainless steel adapter, protection starts at the surface: each coating gets its own packing – interleaves, bags or trays, in sealed export cartons, palletised and marked as you direct.
