Aunov Tech manufactures the Brass Hex Bushings and Pipe Inserts in brass on a single production floor. In operation, the CNC machined part delivers the precise turned or milled geometry the assembly mounts to. The same floor forms, machines and inspects the part, keeping first-article quality through scheduled runs without re-quoting the job elsewhere.
Product overview
For this brass bushing, the drawing centres on, wall thickness control, flange geometry and the sealing surface, audited against the approved sample at each production release.
Die work and machining for this brass bushing sit on the same floor, so feasibility questions are answered on the shop floor, with process data archived for repeat orders.
How the part is produced
The route for this brass bushing is fixed and repeatable: The shell is drawn from a blank in successive stages, annealed where the wall thins; the finishing operations hold the concentricity the drawing calls for.
The bracket tooling and setup record is stored against the part number, so nothing depends on someone remembering. The approved bracket sample governs later runs, and any grade change is agreed in writing first.
Materials and finishing
Base materials in stock: cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and this brass bushing runs in H62 brass.
The surface treatment is picked to match the service conditions: polishing, plating in zinc, nickel or chrome, anodising, powder coating, electrophoresis and passivation. It is written into the drawing for this brass bushing, so it cannot drift between batches.
Production batches are gauged to the signed first article, and material certificates are kept per batch.
Quality control
An ISO 9001 certified system governs production: stock arrivals are checked against mill certificates, first-article geometry is confirmed on the CMM, and later batches follow the sampling plan agreed at approval. The bracket first article is CMM measured – threads gauged to class, diameters on the record. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the report is packed with the shipment.
Where the part is used
The brass bushing sits in industrial and appliance assemblies in both OEM and aftermarket supply.
A single design of this brass bushing is often reused across a product family, so a single grade and coating can cover each application, and the drawing stays common.
Options and variations
Frequently varied options
The usual variables are material and finish for the service environment, thread classes, seat finishes, milled features, cross-holes and plating or anodizing to the print, and volume – from validation prototypes to scheduled call-off batches.
Each variation is priced with its tooling effect made visible, so decisions are easy to make.
Specifications
| Item | Brass Hex Bushings and Pipe Inserts |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – DFM notes are returned before any tooling is cut; changes are priced before they are made. |
| Tooling | Die design and toolmaking stay in house, so no tooling step is outsourced, and the charge is refundable against agreed volumes. |
| Samples | Sample parts are measured and reported before submission, so any deviation is corrected at sample stage. |
| Materials | H62 / H65 brass, 0.8-4.0 mm, selected for conductivity, fine surface detail and corrosion resistance on this bushing. |
| Surface finish | Plating, powder coating, anodising or polishing, per the print; masking and laser marking available where needed. |
| Processing | Coil-fed stamping, deburred and finished to the print; in-process checks sit between stages, not only at the end. |
| Equipment | 5-250 T presses running progressive and compound dies, with in-house toolmaking to keep dies and fixtures maintained. |
| Tolerance | +/-0.03 mm on pierced holes, +/-0.1 mm on formed sections; critical dimensions carry CMM data with the shipment. |
| Delivery terms | FOB with DDP offered for EU and US addresses; payment T/T or L/C, freight quoted to destination. |
Packaging and delivery
Packaging protects the finished surfaces of this brass bushing: interleaves, polybags or formed trays are selected according to the coating, then cartons are sealed and palletised, with marks and documents as you specify.
