New conical extruder marketed for low-output applications

This manufacturer of plastics processing machinery has extended its new range of conical profile extruders with the lower-output KMD 43 K/P, designed to offer processors a flexible, low-maintenance, compact machine that also is said to offer an excellent price/performance ratio.

This new introduction from KraussMaffei Berstorff (Munich, Germany) completes the lower end of the company's conical series of extruders. It includes a redesign of the conventional conical screw from the feed to the compression zone to ensure even more reliable plasticizing and homogenization performance, as well as improved heat transfer from the barrel heating system in these zones. The screw's preheating zone especially is longer than in the previous series, with the extra length helping ensure a stable process and optimal melt homogeneity, reports the company.

Output with KMD 43 K/P 20 can be up to 100 kg/hr. The target market clearly is profile extrusion processing of applications with lower throughput requirements. Despite the longer processing unit, the overall length has been reduced slightly compared to previous models. —[email protected]
