AONA Pipe Hole Punching and Collar Forming Machine

AONA Pipe Hole Punching and Collar Forming Machine

This machine forms a raised collar around an opening in the pipe wall. The collar provides a mating surface for a branch in parts such as duct sections or tubular assemblies. The finished geometry depends on the opening diameter as well as the height and shape of the collar. Provide drawings of the main tube and the mating part so the supplier can match the tooling to the section, wall and material. Measure the inside diameter, height and uniformity of the formed collar. Test the branch fit around the full opening and ask for a sectioned sample if the remaining wall thickness in the formed area is critical.
