An aluminum drum shell with vent holes, drawn deep and pierced. The cylinder wall is seamless, so the drum holds whatever it houses away from dust and moisture except through the controlled vents. Aluminum keeps rotating or portable assemblies light.
Function and Design
A drum shell looks like the simplest item in a catalogue and is often the most demanding to make consistently. The drum shell tolerances that matter are confirmed with capability data before pricing is agreed.
Design Highlights
- Vents are pierced with hard tooling after forming – clean edges, exact placement, no rework.
- Tooling stays in house, so volume prices do not carry a third-party markup.
- Small-batch trials are available before volume production.
- Material: Stock flexibility is the point: drum shell orders have run in carbon steel, stainless, aluminium and brass.
- Process: the drum shell is deep drawn, then deburred and finished on the second operation, burr-free piercing on the second operation.
- Finish: Surface treatment is chosen for the duty the drum shell sees: plated, coated or natural per print.
- Size: Drum shell dimensions follow the print, feature positions held to the drawing tolerances.
- Custom: OEM/ODM to drawing; the drum shell is quoted from your print with material advice included.
Where It Is Used
