Product category: Twin screw extruders


The planning of the process part of MARIS co-rotating twin-screw extruders concerns a group of functional modules composed of barrels and, at their inside, of transport and kneading elements at variable geometry, which are mounted on shafts for the motion/shear transmission.
The concept of the functional modules originated from the necessity of achieving a perfect correspondence between the extruder hardware component and the process phases that can be identified with whatever compounding or reactive extrusion.
The equipment capacity to meet with the process requirements can be found, first of all, in the technicians ability to precisely establish the physical or physic-chemical phenomena occurring inside the machine, both in qualitative and in quantitative terms.

Maris presents the new HT Series of Extruders, which represents the experience gained from more than 50 years of working in this specific field.

This Line of machine is characterized by innovative technological solutions, which have allowed the use of very high power.
Pioneering solutions have also been applied to the compounding resulting in special new screw profiles to produce not only very high quality compounds, but also an increase in output up to 100%.

More flexibility, more throughput, more competitiveness.
To the above market requests Maris answers proposing a new TM extruder HS series, characterized by a D/d ratio 1,65, with a maximum screws speed of 1300 rpm. The torque has been increased of more than 20%, with respect to the HT series.
This solution allows to use a bigger free volume, and an enhanced available torque, permitting a production increasing, either in case of high power request or when it is necessary to feed elevated percentage of fillers and/or additives.

 Thanks to the most performing materials used to manufacture some of the elements composing the extruder, these machines can be applied in the more advanced compounding and reactive extrusion processes.

Product category: Twin screw extruders


Maris co-rotating twin-screw extruders of VM series have been designed to increase the performances, for those processes which require, particularly, big quantities of soft fillers, mainly having low bulk density or long residential time (reactive processes) or efficacy removal of volatile components (solvents and monomers) present even in high percentages.
Characterized by a ratio D/d of 1,78 and a maximum screws rotation speed of 1800 rpm, the specific torque value applied with respect to the cubed screws inter-axle, and the consequent advantages are:

Higher output
Costs and investments reduction
