Extrusion International 2-2022

21 Extrusion International 2/2022 „ MP3, an Italian company belongs to I.L.P.A.- Holding. Their specialised factory in Valsamoggia facory manufactures high quality ABS, ABS/PMMA and PS sheet both for the furnitures and building industry and for thermoformed technical parts for vehicles, thermo sanitary etc. In addition to the closed loop recyclingof all internal PET scrap, MP3 now focuses on increasing the amount of recycled inter- nal scrap from other thermoplastics, ABS or PS in their fi nal products. Five years ago, MP3 already replaced three of their existing screen changers with Gneuss SFXmagnus units on one of their sheet lines as previously they had been unable to use high percentages of recycled material without compromising the product quality. This sheet line consists of one main extruder and two co-extruders. PS, ABS and PMMA are processed on this line, with up to three colour changes daily. Thanks to the replacement of the screen changers withGneuss systems, they were able to add up to 50 % regrind without either process disturbances or quality issues, evenwith a high contamination load. The SFXmagnus Screen Changer is characterised by its large active fi ltration area for its overall external dimensions which means that it is especially well suited for retro fi tting to exist- ing lines. As with all the Gneuss Rotary Filtration Systems, the screenpacks can be changed during normal production, with- out pressure spikes or other disturbances. Consistent sheet surface quality can be ensured and this represents a competi- tive advantage for MP3. In 2020, MP3 retro fi tted another line with three SFXmagnus Rotary Filtration Systems and a further line was retro fi tted with another three units early in 2022.
