Recycling with MAS
Twin compound systems

The recycling solution for
high requirements

MAS twin-com­pound­ing sys­tems pro­duce recy­cling com­pounds of par­tic­u­lar­ly high qual­i­ty. The com­pound­ing duo com­bines two con­i­cal­ly co-rotat­ing twin-screw extrud­ers and a con­tin­u­ous CDF melt fil­ter , meet­ing even the high­est qual­i­ty appli­ca­tions and chal­lenges. The flex­i­ble and ver­sa­tile twin-com­pound lines mix plas­tic frac­tions with a wide range of addi­tives in a tar­get­ed man­ner, stand­ing out due to the gen­tle incor­po­ra­tion that meets all require­ments. We would be hap­py to pro­vide you with a com­pre­hen­sive con­sul­ta­tion on the ide­al twin-com­pound line for your appli­ca­tion.

OUTSTANDING ADVANTAGES

High quality
regranulation

twin-com­pound lines can be suc­cess­ful­ly used for mate­ri­als that are dif­fi­cult to degas

Extended
Material addition

chem­i­cals and addi­tives can be added before and after the melt fil­ter; ide­al for sub­stances that are incom­pat­i­ble and/or can­not be fil­tered

Homogenization

good con­tin­u­ous fil­tra­tion and strong degassing even of mate­ri­als that are dif­fi­cult to degas

Multi-level blending

top-qual­i­ty out­put gen­er­at­ed from addi­tives

Energy efficiency

low tem­per­a­ture, low shear, gen­tle treat­ment

Upcycling for the highest quality

The regran­u­la­tion of plas­tic frac­tions focus­es on the tar­get­ed mod­i­fi­ca­tion of prop­er­ties in order to opti­mize them for fur­ther pro­cess­ing and pro­duce high-qual­i­ty prod­ucts. In In con­trast to the re-com­pound line , the twin-com­pound line uses a sec­ond twin-screw extrud­er after the CDF melt fil­ter. Valu­able addi­tives of the high­est qual­i­ty can be added at sev­er­al levels—both before and after fil­tra­tion. This mul­ti-stage adjust­ment of the pel­lets enables opti­mized, tai­lor-made addi­tive appli­ca­tions. Sub­stances that are not com­pat­i­ble with one anoth­er can be added sep­a­rate­ly. Like­wise, very expen­sive addi­tives do not have to pass through the melt fil­tra­tion process and can there­fore opti­mal­ly devel­op their desired prop­er­ties. Fur­ther­more, fibers can be added even more gen­tly and sup­ple­ment­ed with high­ly spe­cial­ized sub­stances such as glass fibers, car­bon fibers, or glass beads. MAS twin-com­pound sys­tems are suit­able for a wide range of recy­cled mate­ri­als and com­pen­sate for vari­able inputs quick­ly and effi­cient­ly. Our experts will respond pre­cise­ly to your wish­es and require­ments in order to make your upcy­cling process­es as sim­ple, fast, pre­cise, and high-qual­i­ty as pos­si­ble. Com­pre­hen­sive test pro­ce­dures for your lines (whether planned or already in exis­tence) based on the infor­ma­tion and data you pro­vide ensure the high­est qual­i­ty regran­u­late.

How the
Twin Compound Line Works

All recy­cling frac­tions, such as mate­ri­als with low bulk den­si­ty or regrind, are mixed with addi­tives and fillers in the first con­i­cal­ly co-rotat­ing twin-screw extrud­er. Impu­ri­ties such as pieces of wood, paper, non-melt­ing for­eign plas­tics, or rub­ber are removed with the con­tin­u­ous CDF melt fil­ter after the first twin-screw extrud­er.

The mate­r­i­al then enters anoth­er MAS twin-screw extrud­er. Fur­ther addi­tives, fillers, rein­force­ments, and fibers can be added here. The large feed open­ing enables the rapid intro­duc­tion of long and irreg­u­lar fibers, such as nat­ur­al, wood, or car­bon fibers. The mate­r­i­al in the twin-screw extrud­er is also effi­cient­ly degassed thanks to the large melt sur­face. The con­i­cal design enables pres­sure to be built up for the sub­se­quent pel­letiz­ing process with­out the use of an addi­tion­al melt pump, which in turn increas­es ener­gy effi­cien­cy. The mate­r­i­al is pel­letized using strand, water ring, or under­wa­ter pel­letiz­ing.
