Maris America Corporation is the new North American venture of F.lli Maris S.p.A. Maris S.p.A. is a manufacturer of twin-screw co-rotating extruders. They have been manufacturing twin screw co-rotating extruders globally for over 40 years now. All of the machine work and assembly for Maris extruders is done in their Rosta (TO), Italy factory.
MARIS S.p.A. rises at the beginning of 60's and starts with the production of extruders and die-cuttings for pipes and profiles. Nevertheless, MARIS followed very carefully the growth of new polymeric products and the relevant technological developments and guessed with considerable advance the increasing importance of compounding as a strategic phase in the plastic materials growth.
Therefore, at the beginning of the 70's MARIS decided a total transformation by carrying out the manufacturing of co-rotating twinscrew extruders with interchangeable functional modules. After twenty years, this compounding technology has proved to be winning one and today MARIS is one of the leading companies on the international scene. Read the full story
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 a 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 physico-chemical phenomena occuring inside the machine, both in qualitative and in quantitative terms.
