摘要:
A method and a mould for manufacturing pellets of hot-melt ink are disclosed wherein use is made of a multiple mould containing at least three dies detachably attached to one another which define mold cavities and corresponding filling holes. In the moulding process, the cavities are overfilled such that after solidification ink protrudes in the filling openings formed in a single die and prior to removal of the pellets from the mould cavities, the die containing the protrusions is separated from the other dies whereby the ink pellets formed are substantially free of holes and/or protrusions hampering the free flow of such pellets when introduced in a dosing system.
