A large-diameter aluminum tube duct drawn from flat sheet – sizes this big demand careful blank-holder control to avoid wrinkles. The seamless duct is used in air handling and dust collection, where a rolled seam would leak and add turbulence.
Function and Design
Most of the difficulty in a large diameter tube is invisible: wall consistency, concentricity, burr control. That is why the large diameter tube is inspected between operations, not only at the end.
Key Features
- This is the family view; the part you receive follows your drawing.
- Long runs are economical because tooling and capacity are in house.
- Trials before volume: small quantities can be run to your drawing first.
- Material: No fixed grade – the drawing governs; stock covers steel, stainless, aluminium and brass for large diameter tube work.
- Process: the large diameter tube is deep drawn from coil or blank, trimmed and pierced in subsequent dies.
- Finish: Surface treatment is chosen for the duty the large diameter tube sees: plated, coated or natural per print.
- Size: Large diameter tube size to drawing, with the agreed version governing every later batch.
- Custom: OEM/ODM to drawing; the large diameter tube is quoted with real lead times, not estimates.
Applications
Typical applications include electrical enclosures and junction boxes, battery and energy-storage components, lighting reflectors and covers.
Our Production Advantage
We draw in house on maintained presses and inspect first articles on the CMM. Tears, thinning and rim condition are checked at the press, not discovered at assembly.
Ask for a quotation: material options, tolerances and tooling cost are confirmed in writing.
