Background: Polyram is a leading international supplier of high-performance thermoplastic compounds. While producing PET compounds, we had to preform a screw-pull on a weekly basis as the polymer got stuck to the screw and forced to stop production until this got solved.
- Technology: extrusion machine with a 70 mm screw.
- Transition: PET natural to PET natural.
- Goal of purging: reducing the need for screw pull.
- Solutions: Ramclean 800.
- Results: Ramcleam cleaned the contamination within 15 minutes as can be seen in the photos below. This reduced the need to perform screw-pull from once a week to once a month!
