Foam extrusion die. Disadvantage of assembly

摘要

When extruding a foamable material into a vacuum chamber extruder, the die and closure for the chamber are mounted in such a way that they can be moved to and from the chamber (46). The die has lips (14) which are adjustable when the chamber is closed. Continuous manufacturing of foamed billets can occur with easy cleaning of the plant. The die is connected via a bellows-like device to a tube, and is connected to an extruder which is also movably mounted.
