Sus­tain­abil­i­ty is one of the cen­tral glob­al issues of our time. Glob­al warm­ing threat­ens the world with pro­longed heat waves, droughts, floods and dev­as­tat­ing weath­er events. Reduc­ing the con­sump­tion of nat­ur­al resources and CO2 emis­sions is one of the most impor­tant mea­sures need­ed to min­imise the extent of glob­al warm­ing. The plas­tics indus­try is urgent­ly required to find new ways to save nat­ur­al resources and reduce ener­gy con­sump­tion as much as pos­si­ble.

Even dur­ing the devel­op­ment of the MAS extrud­er, atten­tion was paid to using as lit­tle ener­gy as pos­si­ble. The sav­ing of up to 30% ener­gy com­pared to con­ven­tion­al extrud­er types became one of the most impor­tant fea­tures of the MAS extrud­er.

Its patent­ed con­i­cal, co-rotat­ing design allows for low­er screw speed, which cre­ates less fric­tion and thus enables low­est melt tem­per­a­tures. The result: low­er heat­ing pow­er and short­er res­i­dence time of the melt in the pro­cess­ing unit and thus ide­al con­di­tions for:

  • gen­tle extru­sion process
  • enor­mous reduc­tion of ener­gy con­sump­tion
  • Min­imis­ing CO2 emis­sions and the car­bon foot­print


The pic­ture below shows an exam­ple of how the MAS 93‑K extrud­er with a CDF 500‑D melt fil­ter con­sumes sig­nif­i­cant­ly less ener­gy. Assum­ing a price of 0.25 euros per kilo­watt hour, ener­gy sav­ings of up to 1,600,000 kilo­watt hours lead to sav­ings of up to 400,000 euros per year!
