EXTRUSION RECYCLING & COMPOUNDING

Product catalog summary

Overview
The MAS Extruder is an advanced system that integrates recycling and compounding processes, combining the benefits of a co-rotating parallel twin screw extruder with a conical screw design. This system is designed to maximize added value in production by offering superior plastification and homogenization.

Technical Highlights

Compact design with a small footprint.
Conical, co-rotational twin screw system for superior homogenization.
Large in-feed opening suitable for low-density materials like films and fibers.
Cascade configuration for processing heavily printed films.
Operates at low melt temperatures, reducing energy consumption by up to 40%.

Configurations
The MAS Extruder is available in various configurations, each suited for different material outputs:

MAS 24: 20-35 kg/h
MAS 45: 200-300 kg/h
MAS 55L (K): 400-700 kg/h
MAS 75 (K): 700-1200 kg/h
MAS 90 (K): 1000-1800 kg/h
MAS 93 (K): 1200-2500 kg/h

Note: Output depends on polymer type, filtration finesse, and bulk density.

Cascade Extruder
The MAS Cascade Extruder is designed to reprocess materials with high contamination levels, such as heavily printed materials. It features three vent ports and a melt distribution system, allowing for efficient degassing and re-compounding in a single step.

R-PET Process for Food Contact
The MAS R-PET process is FDA-approved and meets EFSA criteria for direct food contact. It is a modular system that can be tailored to customer needs, utilizing existing drying equipment if desired. Key components include:

Pre-Drying: 3 hours at 150°C
Dozing: Gravimetrical or Volumetric
MAS Extruder: Operates at low melt temperatures with short residency time
Extruder Degassing: Vacuum system < 10 mbar

Catalog excerpts

EXTRUSION RECYCLING The MAS EXTRUDER combines the familiar, superior, plastification and homogenization of a co-rotating parallel twin screw extruder with the specific advantages of the conical screw design; a key element of this integrated recycling and compounding system. ADDED VALUE IN PRODUCTION - Processing of undried PET, PLA » Re-compounding The MAS EXTRUDER is perfectly suited for any application when a variety of product requirements need an individual, high quality solution. TECHNICAL HIGHLIGHTS - Compact design; Small footprint » Conical, co-rotational twin screw system - Superior homogenization - Large in-feed opening - Process low density materials (Film, Fibers, etc.) - Cascade configuration for heavily printed film - Low melt temperatures - Reduce energy consumption by as much as 40% CONFIGURATIONS TYPE e.g.PE/PP/PS/PET e.g.PE/PP/PS/PET * Depending on polymer, filtration finesse, bulk density, etc. NOTE: Technical data subject to change.

The MAS Cascade Extruder makes it possible to reprocess materials (heavily printed materials, recycled mat al s with high contamination levels etc.) that are difficult to de-gas on conventional extrusion lines. The Cascade works in conjunction with an uy pending 3 vent ports and a melt distribution s MAS has developed an R-PET process that has received a “No Objection Letter” from the FDA. The process also meets the EFSA criteria for direct food contact. It is a modular system that can be configured to the specific needs of each customer. Since conventional flake drying is used it is possible...
