Twin Screw Extrusion Equipment

EXTRUSION EQUIPMENT

The MAS Extrusion system is the only system that combines two major processes – recycling and compounding – into one. Simplicity at its best.

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.The MAS extruder is perfectly suited for any application when a variety of product requirements need an individual, high quality solution.

Maximum Added Value in Production

The MAS Series of plastic recycling extruders offers a wide range of production capacity from 200 lbs/hour to 6000 lbs/hour (depending on model, polymer and other variables).

Compact, robust, durable
Thanks to the conical design MAS has been able to construct an extruder with extremely large back pressure bearings that allow a high torque input into the extruder screws, especially in the area where it is needed most (Melt Section). The screw diameter in the feed section is approximately twice as big as the pump section of the screw.

Best quality in PET and PLA extrusion

The MAS plastic extruder is perfect for processing A-PET, G-PET, R-PET, PET or PLA both for re-pelletizing and for direct extrusion into final products. The large feed section of the conical extruder supports feeding of both PET flakes (PET bottles, preforms) and pellets as well as sheet regrind. With a combination of venting ports and a feed throat under a high-performance vacuum, the MAS system can process PET and PLA materials without the need for pre-crystallizing or drying.

As the extruder’s intake volume is significantly greater than the discharge volume, an extremely high screw fill level is achieved. This helps to achieve high output values at slow screw speeds and at correspondingly low melt temperatures. This results in excellent color values and minimal IV loss.

When producing an FDA complaint pellet or sheet, the MAS Extruder can be combined with a standard crystalizing and drying system or the advanced KREYENBORG Infrared Dryer.

THE MAS CASCADING EXTRUDER

MAS Plastic Extrusion System - eFactor3

The MAS Cascade Extruder makes it possible to reprocess materials (heavily printed materials, recycled materials with high contamination levels etc.) that are difficult to de-gas on conventional extrusion lines. The Cascade extruder works in conjunction with an upstream Extruder (preferably MAS twin-screw extruder) to reprocess and de-gas the material after the continuous melt filtration.

Depending on the size, the MAS Cascade Extruder is equipped with 2 or 3 vent ports and a melt distribution system to increase the degassing efficiency. With a MAS Cascading system, the two processes of Recycling and Re-Compounding can be combined into ONE STEP .

THE MAS LABORATORY EXTRUDER

The MAS 24 LABORATORY EXTRUDER is the only conical & co-rotating twin screw extruder available for small volume applications. This technology enables the customer to process a wider range of materials including recycled materials on a laboratory scale. It is also ideal for small-scale high-end polymer compounding applications.

When used in conjunction MAS’ range of production scale extruders, recipes can be simply and easily transferred from process to process.

MAS Continuous Melt Filtration

Wood, paper, aluminum foil, non-melting polymers, etc. are very common impurities in the plastic recycling industry. Conventional filter systems using mesh screens are usually unable to cope with even small amounts of these impurities. The MAS CDF continuous melt filter separates contamination such as paper, wood, aluminum, or rubber efficiently and can deal with large amounts of contaminants in the melt stream (up to 5%). A melt pressure-controlled scraper system removes the contamination from the surface of a rotating screen disc into a discharge screw system. The impurities are discharged continuously from the CDF, while the filtered melt continues to flow downstream to the pelletizing system, profile, or sheet die. The melt inside of the filter automatically controls the function of the scraper as well as the speed of the screen and discharge screw(s).
