Innovative efficient melt filtration technology The Upper Austrian MAS-Maschinen- und Anlagenbau Schulz GmbH founded in 2006 has
recently attracted attention due to a range of technical innovations in extrusion and plastic
recycling technology
MAS has made significant developments in terms of efficient melt filtration. The range of
patent-protected continuous melt filtration systems is available in four power levels for flow
rates of from 300 to 2,000 kg/h.
The MAS filter innovation
The objective of MAS developments was to provide answers to problems presented by
several other filtration systems. The focus here was not solely on the flow rate or filter
performance, but in particular on favourable operating costs by minimising wearing parts
as well as high service friendliness. The result is the continuously operating CDF melt
filtration system. Its core component is a rotating filtration disc in the incoming melt flow
and which the pressurised plastic melt flows through. The melt is filtered and then
forwarded to the next system component on the extrusion system. The particles of dirt
such as paper, wood, aluminium and rubber left behind on the filter plate or plastic
particles which have not molten are stripped off using a stationary scraper on the opposite
side of the housing together with a certain amount of the molten plastic, and discharged by
an auger. This conveys the concentrated contaminants outwards (Fig. 1). The melt
pressure regulates the contact pressure of the scraper via a mechanical piston-lever
system. The entire filtration process runs continuously.
The filter discs are manufactured from tempered steel and available for filtration fineness of
from 100µm to 750µm. The filter can be changed very quickly as the housing of the
rotation filter is designed with a vertical division, with both halves of the housing connected
to each other by a hinge, which enables ideal access to the relevant parts. The actual
replacement is extremely simple and can be carried out in around 45 minutes using
conventional tools.

Range with four sizes available
The new filter range consists of three basic models – the basic model CDF 300 (Fig. 3)
with extremely compact design, the midrange model CDF 300-D (Fig. 2) which has been
designed as twin version with 2 x CDF 300 and filter model CDF 500-D with 2 parallel
filtration units with a diameter of 510 mm. The latter accordingly offers the substantial
filtration area of 3.650 cm² (Fig. 3)

All in all, MAS extends far beyond the focus of “melt filtration” and provides a
comprehensive portfolio including the conical co-rotating twin screw extruder as well as the
dry-cleaning and reconditioning system for film flakes.

Fig.2: MAS melt filtration systems are available in three sizes or capacity classes. The photo shows the medium-sized CDF 300-D, consisting of a combination of 2 x 300 mm filtration units. In all this results in an active filter surface of 1384 cm² and a flow rate capacity of between 700 and 1600 kg/h.
