Aunov Tech supplies the Stainless Steel CNC Machined Pump and Valve Components as a stainless steel component manufactured entirely in house. In the assembly, the CNC machined part provides the finished surfaces, threads and seats the mating parts locate on. One production floor covers forming, finishing and inspection, which keeps tolerances consistent from sample to volume on one production route.
Product overview
What defines this stainless steel pump is, the formed envelope, flatness and hole location, recorded on the inspection report for every batch.
Tooling and finishing for this stainless steel pump run under one roof, so feasibility questions are answered on the shop floor, and every step is logged against the part number.
From coil to finished part
This is how the stainless steel pump is built: Machining starts from bar or plate and runs on CNC centres; in-process gauging runs alongside the machines on longer batches.
The block tooling and setup record is stored against the part number, so nothing depends on someone remembering. Process settings for the block are archived, so later runs can be compared with the one you approved.
Materials and finishing
Working stock covers carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper with 304 / 316 stainless steel specified on the drawing for this stainless steel pump.
The coating is matched to the working environment: polishing, plating in zinc, nickel or chrome, anodising, powder coating, electrophoresis and passivation. The agreed finish for this stainless steel pump travels with the part number on every reorder.
Production batches of the block are gauged back to the signed first article, not to a memory of it. Process settings for the block are archived, so later runs can be compared with the one you approved.
Quality control and inspection
Production runs under an ISO 9001 certified quality system: mill certificates cover every delivery of stock, first-article geometry is confirmed on the CMM, and production batches are inspected on a sampling plan. CMM first-article measurement of the block covers diameters and gauges thread class. Tests for torque, leakage or pressure can be arranged when the service demands them, and the report is packed with the shipment.
Applications
This stainless steel pump is used in pump, valve and fluid handling assemblies for customers who buy to drawing.
The same stainless steel pump is often run in more than one assembly, so a single grade and coating can cover each application, and approvals carry across programmes.
Customization and options
The options customers tune most
Variations that come up most often on this stainless steel pump: wall thickness bands, flange geometry, thread call-outs and the surface finish, and the batch pattern – prototype, pilot lot or scheduled production.
The quote for this stainless steel pump separates tooled options from new work, so the cost of a change is visible before you commit. Once approved, the revised block drawing becomes the new master.
Specifications
| Item | Stainless Steel CNC Machined Pump and Valve Components |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – samples are reverse-measured into a controlled drawing; the approved drawing is kept as the controlled master. |
| Tooling | Die design and toolmaking stay in house, so no tooling step is outsourced, and the charge is refundable against agreed volumes. |
| Samples | Samples are issued for approval before the run, so the sample is retained as the master, and later batches are gauged back to the signed sample. |
| Materials | Stainless 304 and 316L, pickled and annealed, 0.5-3.0 mm nominal wall – one grade chosen for corrosion duty and formability of this pump. |
| Surface finish | Surface treatment matched to the duty: plating, coating or polishing; the agreed finish travels with the part number. |
| 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; first articles and batch samples are checked on the CMM. |
| Tolerance | +/-0.01 mm on machined faces, +/-0.05 mm on formed details; critical dimensions carry CMM data with the shipment. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, T/T with deposit and L/C for larger runs; call-off schedules are supported. |
Packaging and delivery
For this stainless steel pump, protection starts at the surface: interleaving, bagging or tray packing is matched to the surface, then sealed cartons are palletised for export, with documents and marks to your instruction.
