Our products

Product category: Screws


The sectioned screws can be produced following most assembly systems, such as through cotter key, broached, or hexagon bar, in nitrided steel or in fully hardened steel. Our long experience allows us to absolutely control the screw pro le in order to obtain the maximum self-cleaning effect.
The barrels can be build up with modular sections with internal circulation of the cooling liquid and with interchangeable bimetallic liners.

Product category: Screws


We can build twin screws with different profiles, among these the variable-pitch thread. We are particularly specialised in the manufacture of conical twin screws. Also in case of twin screws, we can carry out the coating of the flight crests.
We also produce twin bore cylinders, both parallel and conical, which can be delivered with their full equipment, e.g. flanges and installation of cooling pipes.

About us

Company details

The added value of a family-owned business


The history of our company begins as far back as in 1967, when our father Marino Arioli founds his small workshop called M.A.S.T., short for Special Machinery and Equipment for Thermoplastics.
Starting from the realisation of real complete extrusion lines, the main interest is always face in the manufacture of screws and the related rooms for extrusion of plastic materials.
The constant pursuit of growth and a series of technological innovations have gradually made us one of the largest companies specialised in the construction of machine screws and rooms intended for the processing of plastics and related materials.
Now as then we continue with the same passion and dedication handed down from father to son to offer our customers high quality products, made with highly specialised machinery, showing more and more attention to the technological nuances.

100% Manufacturers
Reached the fifty years of activity, MAST today is synonymous of experience and innovation, whose added value is the realization of artefacts absolutely specifically made for the customer: as specialists and 100% manufacturers, we enter the heart of the production process to meet the most particular demands of screws and chambers for the different product sectors users of extruders and injection machines, as well as for the same plant manufacturers. Our establishment houses inside large and next-gen machines, whose productive potential is enhanced by our highly skilled staff. The workshop is always open to the customer to show all the real potential of analysis and production, such as deep-drilling of the cylinders and other advanced technologies.
