Stainless steel cups closed with a perforated lid section, drawn then pierced. Stainless work-hardens during drawing, so these cups gain strength as they form – useful for filter housings that see pressure pulses. Perforation is done with hard tooling for clean, burr-controlled holes.
Function and Design
The cup is small in the bill of materials and large in the warranty claim when it goes wrong. The cup is produced to print, with the features that carry function inspected first.
What Makes It Work
- Perforation is press-pierced with controlled hole pattern, so open area is consistent across every shell.
- Stainless stands up to washdown, humidity and process media – no plating to fail.
- Volume runs are priced against in-house tooling and dedicated capacity.
- Material: Standard stock covers stainless steel (304 / 316); equivalents are feasibility-checked against your print before quoting.
- Process: the cup is drawn in house on maintained presses, wall thickness held to the print.
- Finish: Surface treatment is chosen for the duty the cup sees: plated, coated or natural per print.
- Size: Final dimensions of the cup to your drawing; this page shows the family, your version is quoted from the print.
- Custom: OEM/ODM: send the cup drawing, quotation comes back with manufacturability notes.
Applications
In service you will find this part in lighting reflectors and covers, automotive sensor and motor housings, appliance and HVAC assemblies.
Why Source It From Aunov
Drawing and annealing windows are set from the drawing, not from habit. Tears, thinning and rim condition are checked at the press, not discovered at assembly.
