Our extrusion heads are a crucial factor for the production success. Materialspecific properties like flow behavior, bulk density of the raw material and temperature control are considered when developing an extrusion head. Article and production cavity criteria such as the wall thickness, parison diameter and constant parison ejection speed are integrated in the design of mono, tri-ex and coextrusion heads. Properties of our spiral heads: • Very good melt and temperature homogeneity • Uniform wall thickness distribution over the full circumference around the article • Larger production window and increased application possibilities • Reliable processing of extrusion blow-mouldable plastics HDPE, PP, PC, HMWPE and PCR (Post-Consumer Recycled) and Regrind • Long service life and high operation reliability Advantages: • Repeatable production results lead to an improved quality with potential article weight savings • Exclusion of thin spots, weld seams and flow lines • Straight parison drops at production rates • Reduced color change times and material usage • Reduction of adjustment effort during start-up of production leading to lower material usage • Reduction of die adjustment times
Modern and functional machine design with generously sized access and viewing area.
