Aunov Tech manufactures the Stainless Steel Hose Barb and Threaded Fittings in stainless steel on a single production floor. In duty, the CNC machined part provides the finished surfaces, threads and seats the mating parts locate on. One production floor covers forming, finishing and inspection, so first-article dimensions hold through volume batches without a second supplier involved.
Product overview
For this stainless steel fitting, the drawing centres on, the forming route, the tolerance band and the sealing faces, audited against the approved sample at each production release.
Forming, machining and finishing for this stainless steel fitting happen on one site, so feasibility questions are answered on the shop floor, and the die record stays with your part number.
How it is manufactured
Production follows a defined route: The shell starts as coil or blank and is drawn through single and progressive dies; flanges and rims are formed in the same line, then trimmed to length.
A long probe looks like the simplest item in a catalogue and is often the most demanding to make consistently. The long probe is checked against the drawing at each stage, not only at final inspection.
Materials and finishing
Base materials in stock: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with 304 / 316 stainless steel specified on the drawing for this stainless steel fitting.
Coating and polishing are matched to the end use: plating, 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.
Batch records for the long probe are filed against the part number, so process settings are reused instead of re-invented. That record is what every long probe reorder is built on, so nothing changes silently between shipments.
Quality control
The plant is ISO 9001 certified: incoming material is verified against mill certificates, first-article geometry is confirmed on the CMM, and run inspections follow an agreed sampling plan. First articles of the long probe are CMM measured, with threads gauged to class and diameters recorded. Torque, leak and pressure tests are available where the assembly needs them, and results travel with the batch paperwork.
Typical applications
The stainless steel fitting is fitted into industrial and appliance assemblies for customers who own the drawing and the tooling.
A single design of this stainless steel fitting is often reused across a product family, so wall bands and finishes are selected to cover the widest duty, and the drawing stays common.
Customization and options
The options customers tune most
The parts of the print for this stainless steel fitting that get adjusted: wall thickness bands, flange geometry, thread call-outs and the surface finish, and the batch pattern – prototype, pilot lot or scheduled production.
Quotes for this stainless steel fitting show which options the current die already supports, so you are not charged twice for a feature the die already makes. The long probe drawing revision, once signed, governs all later batches.
Specifications
| Item | Stainless Steel Hose Barb and Threaded Fittings |
|---|---|
| Brand | AUNOV |
| Designing | Design intent is read from the print, and any conflict in the drawing is raised before quoting. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so die cost stays transparent, and first-article timing is measured from the tooling start date. |
| Samples | Production does not start until the sample report has been signed off. |
| Materials | Materials held include carbon steel, 304 / 316 stainless, aluminium and brass; mill certificates and heat numbers accompany the first article. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; finish thickness and adhesion checked on the first article. |
| Processing | CNC turning with milling and drilling in as few setups as the geometry allows; first articles verify the whole flow before the run is released. |
| Equipment | Turning centres fed from bar, with machining centres for milled features, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.005 mm achievable on ground faces where the print demands it; dimensional reports accompany the first article. |
| Delivery terms | FOB Ningbo or Shanghai, T/T with deposit and L/C for larger runs; sea or air freight is quoted to your door. |
Packaging and delivery
Finish comes first when packing this stainless steel fitting: interleaving, bagging or tray packing is matched to the surface, in sealed cartons on export pallets, with documents issued to your instructions.
