World leader in plastics machinery Krauss Maffei Extrusion of Munich Germany has introduced the new 36D single venting twin-screw extruders developed in conjunction with Wavin N.V., Europe’s leading pipe producer.  

Krauss Maffei’s 36D twin screw extruders are designed to produce a comprehensive range of pipe formulations:

  • PVC pipes including smooth, corrugated or foam-core
  • PVC-U pipes made with high filler loadings of more than 30 parts by weight
  • PVC-M pipes or modified PVC pipes
  • PVC-O pipes or bi-oriented pipes 

The HPG (High Performance Geometry) is a specially designed screw that combines an extended preheating zone and an extended metering zone with a new dynamic mixing head.  

The screws are fitted with internal self regulating temperature controls, which are extremely efficient for the cooling of the screw tips and uniform preheating of material by means of the screw root, contributing to a 15% energy saving and optimum melt homogeneity, which reduces the degree of rippling on the pipe surface and improves quality.  

The longer preheating zone (30% more than the previous series) increases the versatility for processing all kinds of formulations and meets the requirements of advanced material processing, better mixing in of colour batches and efficient preheating of highly filled formulations.  

The screw processes highly filled mixtures such as those with high chalk content or up to 100% of recycled material as used in the middle layer for some applications.  

Krauss Maffei’s 36D twin screw extruders can increase throughput performance by up to 10%, providing producers with an extrusion line offering high performance, versatility and excellent value for money.  

Krauss Maffei is represented in Oceania by HBM Packaging & Plastics Technologies .
