ABSTRACT:
A machine producing moulded components in a compactable material, the components being produced in die cavities in a die plate disposed between a filter assembly and a die cover plate, pressure of the compactable material in the die cavities causing filtration and compaction of the material. The compactable material may be a slurry material containing particles of magnetic material for the production of permanent magnet compacts, in which case means may be provided for producing an induced magnetic field around the die cavities before and during the compaction process.
