TWIN SCREW EXTRUDER
MAS

Con­ven­tion­al twin-screw extrud­ers are fre­quent­ly con­vert­ed and con­fig­ured for use in recy­cling. MAS extrud­ers were devel­oped specif­i­cal­ly for this very pur­pose and are a tai­lor-made and future-proof solu­tion for twin-screw extru­sion in the world of recy­cling. The inno­v­a­tive, patent­ed MAS tech­nol­o­gy unites the excel­lent homog­e­niza­tion and degassing per­for­mance of co-rotat­ing twin-screw extrud­ers with robust mechan­i­cal engi­neer­ing and a broad range of appli­ca­tions for a wide vari­ety of recy­cling frac­tions to per­fec­tion. The patent­ed con­i­cal co-rotat­ing design of the process unit fea­tures a large feed open­ing. This means the extrud­er has a larg­er feed vol­ume and can reli­ably col­lect light mate­r­i­al frac­tions at low screw dri­ve. The increas­ing­ly small­er diam­e­ter results in increas­ing­ly slow­er cir­cum­fer­en­tial speeds toward the dis­charge, and thus low­er shear and more envi­ron­men­tal­ly friend­ly plas­tics pro­cess­ing.

This opti­mal bal­ance of con­i­cal process unit, faster pro­cess­ing, short­er reten­tion time, and low­er cone rev­o­lu­tions increas­es the spe­cif­ic through­put vol­ume and reduces ener­gy con­sump­tion. Unde­sired byprod­ucts, gasses, and odors are reduced to an absolute min­i­mum. The result is con­sid­er­ably more usable high-qual­i­ty gran­u­late for the recy­cling and upcy­cling cycle.
