Cofit has been designing and manufacturing  screen changers, including automatic and continuous solutions for plastic extrusion machines since 1968. All components of our screen changers are entirely made in Italy. Most of our technological solutions are patent-covered.

Whether you are processing highly-contaminated, post-industrial or post-consumer plastic, or whether you are committed in filtering clean plastics to guarantee zero-contaminants, screen changers are key elements in your extrusion line.


Gorillabelt T - Screenchanger Cofit
Automatic and continuous screen changer for heavy recycling and high contaminant levels.


Powerbelt - Screenchanger Cofit
Automatic and continuous screen changer for medium contaminated materials (post-industrial recycling) and high contaminant levels.


AP Screenchanger Cofit
Manual continuous and self-cleaning screen changer for low-contaminated materials and high filtration levels.
Fully functional in any sector

Our screen changers can be used in any plastic sectors: agriculture, automotive, building, packaging, food, plastic, polymers, textile, medical, etc.

Screen changers for filtering any polymer

You can use Cofit screen changers to process most raw materials: PET, HDPE, LDPE, LLDPE, PP, ABS, PS, PE, PC, nylon 6, nylon 6.6, PMMA, PA, PVC and more.

Applications: from film to wires & cables

Cofit screen changers can be used in quite a wide set of applications: film, sheet, compounding, wire & cable, pipe, profiles, blown film, blow molding, pellets, recycling, (post-industrial and post-consumer), tapes, technical articles and more.
