Cut pipes, cut costs and become a green manufacturer SICA, an Italian pipe machinery manufacturer, has gone green to contribute to a sustainable world with its new ‘green machines’. Its investment in research and development are geared to machines that reduce process costs, reduce energy and material consumption and avoid plastic dust and chips recycling, assuring a clean and safe environment. One example of how the company achieved this is the patented solution to cut and chamfer PVC pipes without removing material. After years of research, Sica is now promoting a saw that warms up a portion of the pipe, cuts it with a parting knife and then creates a bevel by shaping the heated portion instead of using a chamfer tool that removes material, which creates dust and/or chips. It is a big innovation that allows a noiseless cut and avoids the expensive need for recycling material, cleaning the environment around the saw, and also downstream. In fact, with traditional saws, even when there is an excellent vacuuming system for dust and chips, they cannot completely avoid chip depositing on the saw mechanism or on the cut pipe. Therefore, pipes will always carry part of the scrap material with them on their way towards the belling machine or the end of the line. Avoiding environment pollution and reducing costs is important in order to give the world a chance if it is to be preserved for the well-being of future generations, according to Sica. Another interesting innovation in the field of cutting swarfless pipes is the patent pending electric saw for HDPE, PP-R, multilayer and PVDF pipes. Each cutting movement is electric, therefore silent, precise and extremely repetitive. In particular, for the movement of the cutting arm, the machine has been equipped with an innovative extremely compact servo-actuator, which integrates the motor and gear unit, and which guarantees (when compared to other electric actuators available on the market) superior thrust forces even at high speeds, impact resistance, complete absence of vibrations and high efficiency. These all translate into the superior final quality of the cutting process.
