A hydraulic flanging machine looks simple from the outside, but the right selection depends on what you form, how consistent the flange must be, and how your shop controls safety, changeovers, and uptime. This guide breaks the decision down into practical checks you can use before requesting a quotation, specifying tooling, or planning installation.

In the context of hydraulic flanging machines, precision tolerance refers to how closely the dimensions, angles, curvature, and uniformity of the flanged output conform to design specifications. In other words, it’s the allowable deviation from the intended shape or dimension after forming. Lower tolerance means higher accuracy and less post-processing work.

This is a double-head flange flanging machine designed for round conical vacuum feeder shells, which can press S edges and flanging straight edges.
