The Unison EvBend range of 3-axis tube bending machines is the modern evolution of the original Silkmead tube benders – trusted for decades in aerospace and precision engineering.
Following Unison Ltd’s acquisition of Silkmead, the technology was re-engineered and refined into today’s EvBend 1000 and its larger sibling, the EvBend 2000.
Designed for low-volume, high-accuracy production and prototyping, Unison EvBend machines are relied upon across the aerospace, MRO, Formula 1 and oil & gas industries for precision bending of tube up to 50 mm in diameter.
While manually operated (with servo-assist on the 50 mm), all three bending axes are CNC-controlled via encoders and progressive electromagnetic brakes – delivering consistent, repeatable results at a fraction of the cost of fully automated bending machines.
The EvBend system features a PC-based 15” touchscreen CNC interface, capable of storing infinite parts, processing up to 1,000 bends per component and integrating with CAD and most tube measuring systems.

Since the Unison EvBend 2000 was installed at our facility in Portland, Oregon, we have completely removed our reliance on outsourced pipe bending and have been able to significantly reduce our stockholding.
