CONVERGE CTS This Welex sheet line uses dryer-less co-rotating conical twin-screw technology for processors running PLA and PET.
WHAT'S NEW? Pivoting barrel; also, large thrust bearings enable this machine to produce higher pressure, and a large screw diameter generates greater torque. The line can process the materials at the lowest possible melt temperature. Screws are half the length and weight of conventional parallel screws.
BENEFITS Faster screw removal with almost no added clearance required; due to the screw length, overall line length is reduced by 20 percent; a large feed throat opening allows for the addition of fillers without the need for side feeders, reducing complexity and cost. A higher melt strength makes it easier to process the material, with less sagging at the nip and fewer surface blemishes.
