Energy-efficient pipe extrusion system from Tecnomatic

Pipe manufacturers have started to think in terms of operation cost efficiency, but without compromising the performance of the pipe extrusion lines.

Tecnomatic, which will celebrate its 45 years of experience in the plastic sector, will present at the next K-show innovative solutions in pipe extrusion, to assist customers not only by supplying extruders and die-heads but as well providing complete production systems for a business which is getting increasingly demanding.    

At K 2016 booth (Hall 16 booth D05), Tecnomatic will introduce a further developed version of its extrusion series ZEPHYR in L/D 40, both in a gearless and a traditional version (with gearbox). ZEPHYR is the most performing extruder of Tecnomatic’s product range, it boasts an array of advanced technical solutions which makes them unique models designed for pipe producers looking for even more focused energy saving machines, offering extreme output performance at lower melt temperatures. The innovation spans the entire extruder and includes new spiral grooved bush, screw and motors.

Pipe extrusion is highly dependent on electricity and most of the energy usage is in operating the extruder. The Zephyr series has made this the utmost priority offering extruders with increased screw length and smaller torque and AC water cooled motors, to assure same output of bigger size extruders but with a better energy efficiency.  

The new feed bush ensures minor friction, commonly generated by raw material transport, with subsequent increasing of the specific and total throughput. The further development in screw design, with optimization and enhancement of torque and shearing elements, have improved the output but have also led to process the material at lower melt temperatures.

To meet the requirements for production efficiency the machines are equipped with torque or water-cooled motors (in this case with one or two steps gearboxes) and compact water-cooled inverters. These solutions combined with the mechanical features ensure outstanding power consumption levels, low noise operation (< 74 Db), reduction of workload for maintenance, higher efficiency within wide speed and load ranges, and faster dynamic response.

ZEPHYR extruders are offered in four screws diameter with maximum output at 1.700 kg/h.
