Cups, tubes and anodized aluminum sleeves from a mixed production batch. Anodizing after drawing both colors the shell and hardens its surface, so sleeves resist scratching during assembly. The assortment shows how one press shop can serve steel and aluminum programs in parallel.
Function and Design
Cup tube work is unforgiving: a few hundredths in the wrong place and the assembly will not go together. Tolerances that matter are confirmed with capability data before the cup tube is quoted.
What Makes It Work
- Because the set runs from matched tooling, the variants hold together dimensionally.
- Hard anodic finish: colour and corrosion resistance built into the surface.
- Volume runs are priced against in-house tooling and dedicated capacity.
- Material: No fixed grade – the drawing governs; stock covers steel, stainless, aluminium and brass for cup tube work.
- Process: draw-and-anneal cycle sized to the cup tube depth, blank size logged per run.
- Finish: Finish options for the cup tube: anodising, colour to spec; alternatives quoted against the drawing.
- Size: To your print, family covers the standard size range; dimensioned sketches can be advised before the cup tube is quoted.
- Custom: OEM/ODM cup tube work – first articles verified before production starts.
Where It Is Used

Why Source It From Aunov
Blank size, lubrication and die condition are logged per run. Blank size, lubrication and die condition are logged per run, so when your tenth order matches the first it is not a coincidence.
