Features and Advantages of Round Downspout Elbow Forming Machine

This Type Ⅲ-1 hydraulic auxiliary unit is dedicated to D91 round downspout production. The seaming/locking process is completed on the main downspout line beforehand; this machine handles subsequent bending, S-shape forming, and pipe end swaging. It produces 90°/135° standard elbows and custom S-shaped fittings – swaged ends ensure tight, leak-free joints. Independent start/stop buttons for bending and swaging are mounted separately for single-operator convenience. Compact, easy-to-use standalone unit, ideal for complete D91 downspout lines and on-site fabrication workshops.
