Custom brass cups, boxes and dome shells from customer tooling. Brass draws beautifully – it work-hardens slowly, so deep ratios and sharp inside radii are achievable with minimal risk of tearing. These shells are typically finished plain and rely on brass for built-in corrosion resistance.
Function and Design
Most of the difficulty in a cup box is invisible: wall consistency, concentricity, burr control. The cup box is produced to print, with the features that carry function inspected first.
Design Highlights
- Made to your drawing – this listing shows the family range.
- Repeat volumes are priced with in-house tooling and press capacity in mind.
- Every batch is sampled against the verified first article.
- Material: brass (H62 / H65) – confirmed against your drawing before tooling, so the cup box matches the print on the first batch.
- Process: multi-stage deep drawing of the cup box with interstage annealing as depth requires.
- Finish: The cup box ships natural unless the print calls for plating or coating.
- Size: Overall size to customer drawing.
- Custom: OEM/ODM to drawing; the cup box is quoted from your print with material advice included.
Applications

Why Source It From Aunov
Blank size, lubrication and die condition are logged per run. First articles are inspected on the CMM, production is sampled against the same dimensions, and any drift stops the press.
