Rectangular Sheet-Metal Chassis with Vented Equipment Chassis and Screw-Flanged Edges

Screw-flange hole pitch tolerance and ventilation slot coverage ratio drive the acceptance criteria for a rectangular aluminium vented equipment chassis with screw-flanged edges; screw-flange hole pitch outside ±0.3 mm from the EIA-310D or custom rack mounting standard displaces the fastener centreline and prevents the chassis ears from aligning with the mating rack strip holes, while slot coverage ratio below 30% of the side panel area creates inlet restriction that raises internal junction temperature above the design thermal budget in consumer electronics rack-mount, automotive control box, and OEM equipment chassis applications. Dongguan Dalingshan Wangtuo Hardware Products Factory (Dongguan, Guangdong, ISO 9001 certified)(operating as Welltop)fabricates this rectangular vented equipment chassis with screw-flanged edges at their north of 4,000 m² Dongguan facility, with screw-flange hole pitch, slot coverage ratio, and chassis face squareness measured per your specification at the first article stage. Attach your print specifying flange hole pitch, slot coverage ratio, chassis squareness, and alloy grade. And we will return a pricing from our dongguan team. Typical end markets include aerospace, oil & gas, and shipbuilding.
