Abstract

1,107,939. Extrusion barrels; injection cylinders. XALOY Inc. 12 Sept., 1966 [8 Oct.. 1965], No. 40726/66. Heading B5A. The cylinder or barrel of an injection or extrusion moulding machine comprises a sleeve 12 of relatively high tensile strength steel or non- ferrous metal which extends about one-quarter to one-half the length of main barrel portion 10 from the die or nozzle end thereof. As shown, sleeve 12 tapers, B>C, is preferably applied to portion 10 by a " shrink-on " process, and is bonded thereto by a weld 14. The strain on die 17 as a result of injection or extrusion action by ram 18 is transferred to sleeve 12, the die being attached thereto by bolts 15. Preferably the tensile strength of sleeve 12 is at least three times that of barrel portion 10. An abrasionresistant alloy liner 11 is also provided. Ram 18 may be replaced by a screw impeller.
