EXTRUSION DIE, PROCESS FOR MAKING THE EXTRUSION DIE AND USE OF THE EXTRUSION DIE

摘要

Extrusion die comprised of a multitude of first and second openings connected by a channel, whereby a material to be extruded can be pushed through the cited channels, where the extrusion die essentially has a hollow structure, in which a cavity extends inside the extrusion die in such a way that the cavity at least surrounds part of the channels and is separated from the channels and/or openings, the cavity being further connected to an outer surface of the extrusion die through one or more inlet openings and one or more outlet openings, such that a heat transferable fluid can flow through the cavity of the extrusion die. The wall thickness is limited to 1.5mm.
