The Nickel Plated Brass Threaded Fittings is produced by Aunov Tech from brass, formed and finished under one roof. Once installed, the CNC machined part delivers the precise turned or milled geometry the assembly mounts to. Forming, machining and inspection share one floor, keeping first-article quality through scheduled runs without a second supplier involved.
Product overview
What defines this brass fitting is, the forming route, the tolerance band and the sealing faces, checked by CMM at first article and by gauge in production.
The press shop and machine shop that make this brass fitting share one floor, so a drawing change is absorbed in one step, and the approved sample is kept as the master.
From coil to finished part
Every brass fitting follows the same routed path: The shell is drawn from a blank in successive stages, annealed where the wall thins; piercing and trimming are done in the same die line.
Each nickel-plated ring collar shipment is verified against the master sample before it leaves the shop. Mill certificates are filed per heat, so nickel-plated ring collar traceability survives a change of material batch.
Materials and surface finish
Standard stock includes SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with this brass fitting costed in H62 brass.
Coating and polishing are matched to the end use: polishing, zinc / nickel / chrome plating, anodising or powder coating. The finish on this brass fitting is locked to the drawing revision, so later orders match.
Certificates of conformity and dimensional reports for the nickel-plated ring collar are issued on request.
Quality control
The plant is ISO 9001 certified: material traceability starts with mill certificates, the CMM measures the first article dimension by dimension, and run inspections follow an agreed sampling plan. First article of the nickel-plated ring collar: 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 inspection report ships with each batch.
Where the part is used
The brass fitting is fitted into industrial machinery and equipment assemblies in volume programmes as well as aftermarket supply.
One part number for this brass fitting frequently serves several assemblies, so the tightest tolerance in the family sets the spec, and no re-tooling is needed.
Customization and options
Options changed most often
Typical decisions customers make on this brass fitting: material grade, coating, wall bands, flange form and end closure, with orders run as prototypes, pilot lots or scheduled call-offs.
The quotation for this brass fitting marks what the existing tooling can do, so the effect of a revision on price is clear up front. Both quantity and price break are written into the nickel-plated ring collar quotation.
Specifications
| Item | Nickel Plated Brass Threaded Fittings |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – unusual walls, threads or tolerances are feasibility-checked first; the approved drawing is kept as the controlled master. |
| Tooling | Fixtures and dies are made in house, which shortens both lead time and the change loop. |
| Samples | Production does not start until the sample report has been signed off. |
| Materials | Brass H62 / H65 in strip or bar, 0.8-4.0 mm nominal – the grade picked for machinability and plating adhesion. |
| Surface finish | Natural, plated or coated – the print decides, and the agreed finish is logged; finish thickness and adhesion checked on the first article. |
| Processing | Turn-mill machining, critical diameters finished in one setup; batch records are filed so a repeat order starts from approved data. |
| Equipment | CNC turning centres with bar feeders and 3-/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; dimensional reports accompany the first article. |
| Delivery terms | Delivery quoted per Incoterms 2020 – FOB, CIF or DDP – by sea or air, to your address. |
Packaging and delivery
The finish on this brass fitting dictates how it is packed: interleaving, bagging or tray packing is matched to the surface, in sealed cartons on export pallets, with documents issued to your instructions.
