Extrusion technology Plastics processing

Part 1 Plastics technology KraussMaffei Berstorff plastics e ­ xtrusion lines stand for maximum p ­ roduct quality – from compounding, pipe extrusion up to film and sheet production.

Extrusion technology Plastics processing Single-screw extruders from 250 mm to 800 mm screw diameter KraussMaffei Berstorff builds single-screw e ­ xtruders for mixing, degassing and compounding. The KE 800 extruder with a screw diameter of 800 mm is the world’s largest single-screw extruder. In LDPE synthesis for melt pellet conversion, throughput rates of up to 74 metric tons per hour are achieved. One key step in compounding is the degassing of hydrocarbons and other volatile matter from the melt. This reduces the need for post-treatment of the pellets in silos and protects the...

Left: The world’s largest single-screw extruder for melt degassing Right: Underwater pelletizer with an output rate of up to 74 metric tons/h Pelletizers KraussMaffei Berstorff underwater pelletizers have proven their value as compact and efficient downstream units. Together with our single-screw extruders, they form a system for efficient ­thermoplastics compounding. Areas of application for KraussMaffei Berstorff ­pelletizers include: – olyolefin production (LDPE) with throughput rates p of up to 50 metric tons per hour; – olypropylene compounding with filler content of p 50% and more....
