Abstract

Each object is moulded in a split tool which is parted axially to release the pressing and the hot liquid plastic is fed from an axial outlet to a radial channel section outside the matrix proper, along a telescopic spring loaded, external axially parallel channel to a second radial section leading back to a pair of axial injection nozzles each connecting with one cavity in the closed multiple mould tool assembly (the matrix).
