Small open stainless steel cups – shallow draws where the wall is stretched evenly from the blank. Stainless gives these cups lasting corrosion resistance in washdown or humid environments, and the open form makes them easy to fill, inspect and clean.
Function and Design
What makes a small open cup hard is repeatability – the hundredth piece has to match the first one. The small open cup tolerances that matter are confirmed with capability data before pricing is agreed.
Design Highlights
- Stainless construction means no coating to fail in washdown or humid conditions.
- Burrs are removed and parts cleaned before they enter the box.
- Family page only: your small open cup dimensions and features come from your print.
- Material: stainless steel (304 / 316), with mill certificate and heat-number traceability supplied with the first article.
- Process: multi-stage deep drawing of the small open cup with interstage annealing as depth requires.
- Finish: Natural as standard for the small open cup; plating or coating quoted to the drawing.
- Size: Small open cup dimensions follow the print, feature positions held to the drawing tolerances.
- Custom: Custom work to print for the small open cup, with DFM feedback before quotation.
Where It Is Used
Typical applications include electrical enclosures and junction boxes, automotive sensor and motor housings, battery and energy-storage components.
Why Source It From Aunov
Tooling for the small open cup is maintained against stroke count, so it does not drift during a run. First articles are inspected on the CMM, production is sampled against the same dimensions, and any drift stops the press.
