Manifold plate, manifold comprising a manifold plate, extrusion assembly comprising a manifold, and method of making a manifold plate

Abstract

A manifold plate for a manifold for supplying thermoplastic plastic melt to at least one extrusion head for producing a preform is disclosed. The manifold plate includes: a first plate side and a second plate side, a distribution groove incorporated in the first plate side and extending in a plate plane of the first plate side, and at least one connecting channel adjoining the distribution groove, which is worked into the manifold plate and ends at an outlet opening in the second plate side. The manifold plate is characterized in that the at least one connecting channel is milled into the manifold plate and, in the flow direction, has a course which is curved at least in sections towards the second plate side. A manifold, an extrusion assembly and a method for manufacturing a manifold plate are also disclosed.
