Screw elements, shafts, barrels and dies are machined in our own works; gearboxes are assembled and run in for 24 hours before they meet a screw; every line is tested with material, not only dry-run, and the test video and pellet sample travel with the machine.<\/p>\n<p>That structure decides what we are good at. When a filler masterbatch line has to hold 88% CaCO<sub>3<\/sub> without surging, or a PET line has to keep IV through the die, the answer is usually a screw element, a barrel liner or a feeder setting \u2014 all of which we can change without waiting for a third party.<\/p>\n\n<h2 class=\"sec\" id=\"s3\">What we build<\/h2>\n<div class=\"cards\">\n<div class=\"card\"><h3><a href=\"\/machines\/\">Machines<\/a><\/h3><p>Eleven families, from the KTE-16 lab unit to the KTE-135D and the KTE-T triple screw.<\/p><p class=\"meta\"><b>KTE \/ SE \/ KNE<\/b><\/p><\/div>\n<div class=\"card\"><h3><a href=\"\/applications\/\">Lines by application<\/a><\/h3><p>32 material pages: filler and colour masterbatch, cable compound, engineering plastics, recycling, food and biodegradable.<\/p><p class=\"meta\"><b>32 lines<\/b><\/p><\/div>\n<div class=\"card\"><h3><a href=\"\/projects\/\">Projects<\/a><\/h3><p>Cases, turnkey plant scope and plant footage \u2014 the evidence behind the specifications.<\/p><p class=\"meta\"><b>2,000+ installations<\/b><\/p><\/div>\n<div class=\"card\"><h3><a href=\"\/company\/news\/\">News &amp; exhibitions<\/a><\/h3><p>Six shows in 2025 \u2014 Dubai, Shenzhen, Riyadh, Ho Chi Minh City, Tokyo and Istanbul.
