ABSTRACT:
A pin-barrel extrusion device having a barrel temperature control means between the outer and inner hollow cylinders of the barrel and an apparatus for adjusting the radial depth of penetration of the pins into the inner hollow cylinder is disclosed in which problems due to different rates of thermal expansion of the cylinders in the axial direction are obviated or at least minimized. This is achieved by locating the pins in guide sleeves, which sleeves are detachably mounted in a bore formed in the inner cylinder and pass through aligned bores in the outer cylinder. The outer cylinder bores have a diameter larger than that of the sleeves so that an annular gap is defined between the bores and the cylinder. This provides room for movement of the sleeve if the inner cylinder on which it is mounted expands at a different rate to that of the outer cylinder.
