their very large physical size, the tools are designed for quick changeover, using a special set of mounting plates that are moved by an overhead gantry crane. Many of are unique to each application and are produced in very small tool changeover time, as well as machine setup time, is therefore a key issue and the company now Every pipe that has been bent six weeks of operation has been is excellent – the machine has was installed and there are no signs of any wrinkles! The bend accuracy and ovality of parts are also much better than those we produced on our hydraulic benders.”

where these capabilities will be essential. An ideal manufacturing sequence is to cut a pipe to length, end and then bend it to the required shape. However the limited bending accuracy of its

bending accuracy and repeatability of the Unison all-electric machine to secure an end-to-end bent part by eliminating unnecessary steps.
welded to a cut-to-length pipe – requiring only a single pass through a robotic welding station – before the complete pre-assembled part is presented to the tube bender. The bent part will then immediately ‘straight-through’ manufacturing productivity gains and eliminate expensive scrap.
Unison’s Key Account Manager, Steve Haddrell said: “Framo submerged pumping systems are renowned for their quality and chosen to partner with Unison as it embraces all-electric tube bending technology. There is a growing industry awareness that our all- electric platform is fully scalable and that we can produce machines for bending extremely large tubes and pipes. Regardless of their size, our fully automated set-up and more accurate and repeatable results
than their hydraulic counterparts, making them ideal for precision of experience in designing tube and pipe bending solutions for problems and is widely regarded as an industry innovator. Its standard range of all-electric machines currently spans tube and pipe inches) with an increasing number of custom models extending this capability even further. The interest from markets that have traditionally been the preserve of hydraulic bending machine manufacturers, such as suppliers and subsea equipment, power generation and industrial process industries.
