Steel cups with a perforated filter shell section, pierced after drawing with a controlled hole pattern. The perforations flow media while the drawn body keeps structural strength, a combination used in filter caps, strainer shells and protective sensor screens.
Function and Design
A cup carries one job in the assembly, and every tolerance on it exists to protect that job. Tolerances that matter are confirmed with capability data before the cup is quoted.
What Makes It Work
- Perforation is press-pierced with controlled hole pattern, so open area is consistent across every shell.
- Parts ship deburred and clean, packed to arrive assembly-ready.
- Trial quantities are quoted alongside volume pricing, so you can prove the part first.
- Material: carbon steel (SPCC / DC01 or to print) from verified mills, so repeat orders of the cup land on the same grade every time.
- Process: deep drawing with in-die trim and pierce on the final station for the cup.
- Finish: Natural as standard for the cup; plating or coating quoted to the drawing.
- Size: Quoted from your print, so the cup size you approve is the size that repeats.
- Custom: The cup is made to print – low MOQ on standard items, volume pricing on repeats.
