Aunov Tech supplies the Sheet Metal Progressive Deep Drawn Stamped Parts Aluminum Brass Deep Drawing Froming Tube as a brass or aluminum component manufactured entirely in house. In operation, the deep drawn tube guides or contains the mating part along its bore. Drawing, cutting and measurement sit on one floor, and a design change is re-sampled in one place on one production route.
Product overview
For this aluminium tube, the drawing centres on, the formed envelope, flatness and hole location, re-checked whenever the drawing is revised.
The press shop and machine shop that make this aluminium tube share one floor, so the route from print to sample stays short, and the same die can be re-cut from the original data.
How it is manufactured
This is how the aluminium tube is built: The drawn envelope is produced in stages with anneals between them; piercing and trimming are done in the same die line.
Most of the difficulty in a bearing sleeve bushings, is invisible: wall consistency, concentricity, burr control. Our answer on the bearing sleeve bushings, is process control: fixed setups, recorded parameters and sampling through the run.
Materials and finishing
Materials kept on the floor cover SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with aluminium specified on the drawing for this aluminium tube.
Finish selection follows the working environment: polishing, plating in zinc, nickel or chrome, anodising, powder coating, electrophoresis and passivation. The agreed finish for this aluminium tube travels with the part number on every reorder.
The bearing sleeve bushings, tooling and setup record is stored against the part number, so nothing depends on someone remembering. Any change to the bearing sleeve bushings, drawing is re-approved and re-verified before production continues.
Quality control
Quality management is certified to ISO 9001: material traceability starts with mill certificates, a full CMM report approves the first article, and production batches are inspected on a sampling plan. Wall thickness is measured on the bearing sleeve bushings, first article and followed through the run. Functional testing – torque, leak or pressure – can be written into the plan, and the report is packed with the shipment.
Applications
The aluminium tube sits in industrial and appliance assemblies for OEM and Tier-1 customers.
One drawing for this aluminium tube is commonly applied to several programmes, so the finish is chosen to cover the harshest of them, and cost per piece stays at the volume tier.
Options and variations
What customers usually vary
Typical customer decisions: material and coating for the duty, closed or open ends, wall bands, inside finish ranges, flanges and port features added by secondary ops, and whether orders run as prototypes, pilot lots or scheduled batches.
Changes are quoted with their tooling impact stated explicitly, so decisions are easy to make.
Specifications
| Item | Sheet Metal Progressive Deep Drawn Stamped Parts Aluminum Brass Deep Drawing Froming Tube |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – samples are reverse-measured into a controlled drawing; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Progressive and drawing dies are designed and built in house, so tooling lead time stays under our control, and the charge is refundable against agreed volumes. |
| Samples | Sample approval is documented: dimensions, finish and material recorded for later comparison. |
| Materials | Stock covers carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass; material substitutes are proposed only with your written approval. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; the agreed finish travels with the part number. |
| Processing | Deep drawing on maintained presses, blank size and lubrication logged per run; first articles verify the whole flow before the run is released. |
| Equipment | Mechanical presses 5-250 T plus 250-500 T hydraulics, with in-line annealing, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.05 mm on drawn diameters, tighter bands confirmed against the drawing; finer bands confirmed from capability data before quoting. |
| Delivery terms | FOB Ningbo or Shanghai, payment by T/T, L/C at sight or D/P; sea or air freight is quoted to your door. |
Packing and shipment
The packing method protects the surfaces of this aluminium tube: interleaving, individual bags or trays are chosen by finish type, in sealed export cartons, palletised and marked as you direct.
