Extrusion 7-2016

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

K 2016 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.

t K-show 16’ Tecnomatic will introduce a further develo-

ped 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 pro-

duct 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, offe-

ring extreme output performance at lower melt temperatures.

The innovation spans the entire extruder and includes new spi-

ral 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 in-

creased 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 genera-

ted 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 al-

so led to process the material at lower melt temperatures.

To meet the requirements for production efficiency the machi-

nes are equipped with torque or water-cooled motors (in this

case with one or two steps gearboxes) and compact water-coo-

led inverters. These solutions combined with the mechanical

features ensure outstanding power consumption levels, low

noise operation (< 74 Db), reduction of workload for mainten-

ance, higher efficiency within wide speed and load ranges, and

faster dynamic response.

A comparison between a gearless extruder in size 60.37 and

new Zephyr 60.40 is clearly showing the advantages in the ad-

option of this last solution. (
