Tube I/O Sizing SPM

Machine Description The Tube Expanding SPM is a precision-engineered machine designed to expand the ends or entire length of tubes to achieve tight tolerances, improve fitment, or prepare them for subsequent forming, welding, or assembly processes. Ideal for stainless steel, mild steel, copper, and alloy tubes, this special-purpose machine ensures uniform expansion using high-force hydraulic or mechanical systems. It is widely used in manufacturing exhaust components, EGR tubes, heat exchangers, and flexible metal hose assemblies. Features • Accurate inner and outer diameter sizing for tubes • Compatible with stainless steel, mild steel, copper, Inconel, and more • High-force hydraulic or servo-driven operation for precision sizing • Customizable tooling for various tube sizes and thicknesses • Ensures roundness, dimensional accuracy, and fitment consistency • Suitable for both welded and seamless tubes • Optional dual-head configuration for simultaneous I/O sizing • Rugged construction for industrial, high-volume usage • PLC-controlled or foot-switch-operated for ease of use Technical Details
