Dual- and Multi-Layer Extrusion

Different types of heads are available for dual- and multi-layer extrusion. Depending on the chosen crosshead extrusion of dual-layer, dual-layer plus co-extrusion of stripe/skin or triple layer plus co-extrusion of stripe/skin can be done.The number mentioned in the type specification below identifies the size of the engaged tools. All dimensions must be seen as guide figures. For the selection of the most suitable head size the following parameters are decisive: product dimensions, required capacity and the selected material.
