Aunov Tech supplies the Stainless Steel 3-Piece Flare Fitting as a stainless steel component manufactured entirely in house. On the product, the CNC machined part carries the controlled features that forming alone cannot hold. Drawing, cutting and measurement sit on one floor, so first-article dimensions hold through volume batches without re-quoting the job elsewhere.
Product overview
The specification of this stainless steel fitting turns on, the forming route, the tolerance band and the sealing faces, re-checked whenever the drawing is revised.
The press shop and machine shop that make this stainless steel fitting share one floor, so feasibility questions are answered on the shop floor, and nothing about the route depends on a third party.
How it is manufactured
Manufacturing runs on a controlled process path: Drawing runs from flat blank to finished envelope in one controlled sequence; after drawing, critical faces are machined and the part is degreased and gauged.
Production batches of the flanged pump housing are gauged back to the signed first article, not to a memory of it. The signed flanged pump housing sample remains the reference and is kept with the job file.
Materials and surface finish
Everything is drawn from a fixed stock list: carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this stainless steel fitting is costed in 304 / 316 stainless steel.
Coating and polishing are matched to the end use: polishing, plating in zinc, nickel or chrome, anodising, powder coating, electrophoresis and passivation. The choice is recorded on the drawing for this stainless steel fitting, so the decision never has to be made twice.
Production batches of the flanged pump housing are gauged back to the signed first article, not to a memory of it. First article, drawing revision and material cert travel with each flanged pump housing batch.
Quality control
Production runs under an ISO 9001 certified quality system: mill certificates cover every delivery of stock, first articles are measured on a CMM, and routine sampling keeps batches aligned with the first article. First article of the flanged pump housing: CMM data on diameters, thread class confirmed by gauge. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the report is packed with the shipment.
Applications
This stainless steel fitting is used in industrial equipment and general assembly work in volume programmes as well as aftermarket supply.
A single design of this stainless steel fitting is often reused across a product family, so a single grade and coating can cover each application, and cost per piece stays at the volume tier.
Customization and options
The options customers tune most
Options customers tend to adapt on this stainless steel fitting: 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 programme starts as a sample or a full release.
The quotation for this stainless steel fitting is explicit about what the die already covers, so new tooling is only quoted where it is genuinely required. Who owns the flanged pump housing tooling is spelled out on the quote.
Specifications
| Item | Stainless Steel 3-Piece Flare Fitting |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – unusual walls, threads or tolerances are feasibility-checked first; the agreed version governs every later batch. |
| Tooling | Die design and toolmaking stay in house, so the die charge appears as its own quotation line, and maintenance is tracked against the part number. |
| Samples | Samples are issued for approval before the run, so the part is proven before it is made in volume, and production starts only after your written sign-off. |
| Materials | Materials held include carbon steel, 304 / 316 stainless, aluminium and brass; the final grade is fixed with the drawing review. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; masking and laser marking available where needed. |
| Processing | Bar-fed turning with milled features completed in the same clamping; batch records are filed so a repeat order starts from approved data. |
| Equipment | 12 CNC turning centres with automatic bar feeders; secondary ops run on CNC turning centres, inspection on the CMM. |
| Tolerance | +/-0.01 mm on ground diameters, with GD&T taken from your print; capability is checked on the first article before the run continues. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, T/T or L/C, with D/P accepted on repeat business; each volume tier carries its own quoted price. |
Packing and shipment
This stainless steel fitting is packed to protect the finish: interleaving, bagging or tray packing is matched to the surface, in sealed cartons on export pallets, documented and marked to your instruction.
