The Maxi-Blast Cleaning System is ideal for cleaning extrusion, injection and even twin screws without harsh chemicals or long hours of hand cleaning. Our blasting media, used in conjunction with the Maxi-Blast Screw Cleaning System substantially reduces cleaning time and potential to damage components. The plastic media is blasted out of a pressurized hose that only strips surface buildup, leaving the components untouched and undamaged. The screw is then ready for reuse with no further cleaning or prepping needed. The plastic media is continually recycled, increasing longevity and cost savings.
