KraussMaffei Berstorff will
showcase the KME 60-41 B/R, which represents the latest single-screw
extruder series with, at a processing length of 41L/D, the longest
processing unit. This market launch serves to highlight its role as one
of the most important players in PO pipe processing. The exhibit is
combined with the KM-RKW 34-250 IPC pipehead. With its efficient
internal pipe cooling system, this pipehead allows for cost-effective
pipe processing and increased output.
High-performance extrusion with disproportionately increased
throughput
With its actual processing length of 41L/D, the new series is ideally suited to
high-performance PE- and PP-pipe extrusion. "When we were redeveloping
this series, we incorporated elements from our 36D series, which has
enjoyed significant success for some time and boasts customers from
across the globe, and combined these elements with a new processing
concept. We are now delighted to be able to present this world first to our
customers at the K 2013 trade show," says Peter Roos, President of the
Extrusion Technology segment and of the KraussMaffei Berstorff brand.
"True to our motto 'Lengths in front', the new series, with its patented
processing concept and 41L/D screw, delivers a disproportionately increased throughput, while at the same time maintaining low melt
temperatures and high product quality," emphasizes Roos. The consistently
high outputs and unfailingly excellent product quality that result from this pay
dividends for extrusion shops. "The new series puts the finishing touch to our
product portfolio and we are now equipped to deal with all current and future
market demands," continues Roos.
Patented screw concept and excellent wear-resistant properties
The screw has been designed to exploit the entire length for melting and
homogenizing. This reduces the amount of stress to which the polymer is
subjected, as well as ensuring that plasticization has a reduced impact on
the material properties during the melting process. In addition, an improved
combination of heating and cooling means that the barrel can ensure optimal heat dissipation. A filling opening that has been modified in terms of length and dimensions to accommodate the increased throughput guarantees linear throughput development across the entire speed range. The design of the spiral grooved bush provides low-impact material handling alongside feed stability.
Long machine life is implicit in the new extruder series, with bimetal barrels and optionally through-hardened grooved bushes imparting
excellent wear-resistant properties. The 41D series is available with 45, 60, 75, 90, 105 and 125 mm screw diameters. It joins the successful 36D series, which has already proven its worth, in the KraussMaffei Berstorff singlescrew extruder product portfolio, especially for high-performance extrusion. |
