摘要
The extrusion (1) cavity cooler is an uncooled (sic) fixed material of high thermal conductivity (2) following the die (3). The cooler comprises a gas or liquid held by a seal in the cooling region. The material is a gas or liquid in a balloon in the region. The gas is helium. An Independent claim is included for the corresponding method of extruding and cooling.
