Abstract

Method for manufacturing counterweights for washing machines, comprising the moulding of bodies of plastic material (15, 17) which are then filled, when they are still in the mould (13), with inert material mixed with water. Such a filling material is compacted by letting the counterweights undergo a vibratory compaction phase as they are still in the mould or after they have been removed therefrom.
