Abstract

Barrel for extrusion or screw injection moulding machine, consists of a series of tubular elements assembled end to end. Elements are fitted with individual heaters, temperature sensors etc. The tubular barrel sections are pref. assembled by threaded couplings, though flanged, welded, bonded or clamped assemblies are also claimed. Some barrel sections are designed for special purposes, e.g. to receive the base of a feed hopper or to accept an outlet die head. individual elements may be changed to replace worn sections, change flight/barrel clearances, introduce or move ancillary injection points, vents etc. Barrel length may be changed. Machine is more readily dismantled and moved than designs with massive one-piece barrels. Barrel heating and insulation patterns can be changed.
