Formed End Cap with Square Stepped End Cap and Deep Recessed Cavity

Step depth and cavity opening diameter are verified against your released print during first article review on every square stepped end cap. Welltop's Dongguan CNC milling and fabrication line produces these under ISO 9001 process controls. Step depth determines the axial position of the cap on its mating tube or profile; cavity opening diameter governs whether the mating end inserts cleanly without interference. The facility spans 4,000 m² of floor space, supplying automotive, aerospace, and oil & gas sectors. Both are documented on the inspection record before shipment. The formed end cap body and deep recessed cavity are produced from your signed-off print; step squareness and cavity wall perpendicularity are verified during in-process sampling. Applications include consumer electronics chassis end caps, drone airframe tube closures, and OEM equipment housing end caps. Surface finish follows your drawing callout. Supply — our Dongguan team will confirm feasibility and price with your enquiry.
