Assorted cups, caps and flange bodies drawn from steel. Flange bodies – a cylinder with a wide flange mid-wall – are among the most useful drawn forms: the flange takes fasteners, the cylinder houses the component, and the whole part is one seamless press piece.
Function and Design
The cup cap is judged by the dimension nobody checks until a failure – fit, seal or concentricity. The cup cap is produced to print, with the features that carry function inspected first.
What Makes It Work
- One pressing carries the flange, the sealing shoulder and the locating face.
- Because the set runs from matched tooling, the variants hold together dimensionally.
- Family page only: your dimensions and features come from your print.
- Material: Your drawing decides the grade; cup cap batches have been run in steel, stainless, aluminium and brass.
- Process: multi-stage deep drawing of the cup cap with interstage annealing as depth requires, flange trimmed and pierced in-die.
- Finish: The cup cap ships natural unless the print calls for plating or coating.
- Size: Cup cap dimensions follow the print, feature positions held to the drawing tolerances.
- Custom: OEM/ODM to print: the cup cap quotation includes material advice and tooling cost.
Where It Is Used
In service you will find this part in automotive sensor and motor housings, lighting reflectors and covers, battery and energy-storage components.
Our Production Advantage
Quality on drawn parts is invisible until it fails – a tear in the third batch, a rim that cuts a seal. First articles are inspected on the CMM, production is sampled against the same dimensions, and any drift stops the press.
