Dome cups in assorted sizes drawn from steel sheet. The dome form gives the best stiffness-to-weight of any shell shape, which is why dome cups appear everywhere from appliance feet to sensor caps. Multiple sizes can share die sets with interchangeable punches.
Function and Design
A dome cup size looks like the simplest item in a catalogue and is often the most demanding to make consistently. That is why the dome cup size is inspected between operations, not only at the end.
Design Highlights
- The variants come from matched tooling, so dimensions stay consistent across the set.
- Every part is deburred and cleaned before it is packed.
- First-article verified, then sampled in production – batches match.
- Material: Standard stock covers carbon steel (SPCC / DC01 or to print); equivalents are feasibility-checked against your print before quoting.
- Process: deep drawing on 5-250 T presses, with the dome cup size tooling dedicated to your number.
- Finish: No catalogue finish: the dome cup size surface is agreed on the drawing and confirmed at sample approval.
- Size: Quoted from your print, so the dome cup size size you approve is the size that repeats.
- Custom: OEM/ODM to drawing; the dome cup size is quoted from your print with material advice included.
Applications
It earns its place in automotive sensor and motor housings, lighting reflectors and covers, electrical enclosures and junction boxes.
Why Source It From Aunov
We draw in house on maintained presses and inspect first articles on the CMM. Blank size, lubrication and die condition are logged per run, so when your tenth order matches the first it is not a coincidence.
