A steel ring cup with a notched rim, drawn then notched with shaped tooling. The notches index or clip into the mating part – a functional detail that is cheap when pierced with the right die and expensive when machined later.
Function and Design
Most of the difficulty in a ring cup is invisible: wall consistency, concentricity, burr control. The ring cup tolerances that matter are confirmed with capability data before pricing is agreed.
Key Features
- Made to your drawing – this listing shows the family range.
- Burrs are removed and parts cleaned before they enter the box.
- Trial lots can be run before you commit to volume.
- Material: For the ring cup we default to carbon steel (SPCC / DC01 or to print); the grade is locked before tooling starts.
- Process: multi-stage deep drawing of the ring cup with interstage annealing as depth requires.
- Finish: Natural by default on the ring cup; plating, powder and e-coat options priced with the quotation.
- Size: To your print; dimensioned sketches can be advised before the ring cup is quoted.
- Custom: Custom work to print for the ring cup, with DFM feedback before quotation.
Where It Is Used
Production volumes of this part run in electrical enclosures and junction boxes, automotive sensor and motor housings, lighting reflectors and covers.
Factory-Direct Advantage
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.
Ask for a quotation: ring cup material options, tolerances and tooling cost are confirmed in writing.
