Stamped Stainless Steel Cage Assembly with Perforated Metal Cage Housing and Folded Box Profile

EMC shielding enclosures, ventilated electronics housings, and measurement instrument cases use a perforated metal cage housing where hole pitch uniformity and flange squareness together determine RF attenuation performance and mating panel seating; hole pitch variation above ±0.3 mm creates non-uniform aperture distribution that shifts the effective cut-off frequency of the perforation pattern, while flange squareness above 0.5 mm across the four folded sides prevents flush assembly against the rear back panel. Dongguan Ruishuo Hardware Electronics (Dongguan, Guangdong, established 2016) stamps this stainless steel perforated metal cage housing with folded box profile at their north of 2,000 m² Dongguan facility, with hole pitch, aperture diameter, and flange squareness compared to your print at initial sample check. Ruishuo serves aerospace, communication, consumer electronics, and monitoring equipment perforated metal cage housing applications using hardware stamping and CNC milling. Include hole pitch, aperture diameter, flange squareness, and stainless grade in your RFQ package.
