History of Unison Ltd.

The History of Unison

Since our incorporation we have developed over 30 tube bending machine models to cover 10-250 mm diameter in single-stack, multi-stack and right/ left varieties and delivered to over 21 countries, across six continents around the world.

Unison was established in 1973 to design and build computerized control systems for industry. We designed the first computer controls for several well-known Tube Bending machine manufacturers in the late 70’s and early 80’s.


In 1989 we expanded to design and develop a full range of tube bending machines, going on to design a fully automated set up tube bending machine. This method of control was revolutionary as it enabled all positions and forces necessary to bend a tube to be stored and recalled by computer.

Effective Web Development Solutions

Six years later we developed the first three ‘all-electric’ tube bending machines 20mm, 40mm and 65mm tube capacity. The very first machine went into service in 1996 and is still in production.

The use of the servo technology to control all moving parts has enabled us to build machines for customers with virtually unlimited control features to move the tooling or the part being made - a feature which is completely unavailable to machines using hydraulics.

We have continued to develop all-electric tube bending machinery and our extensive range extends from wire to 10” tube.
