摘要： Moulding apparatus including a die, a first hydraulic ram member for opening and closing the die and a second ram member, contained within the first ram member, for injecting mouldable material into the die. The apparatus may be for moulding permanent magnet compacts in which case means may be provided for maintaining a magnetic field around the material in the die.

摘要： Apparatus for moulding components in compactable materials, including a die plate with die cavities closed by a filter assembly at one side of the die plate, the filter assembly being constituted by a filter block with a grooved or perforated surface and a filter pad in abutment with said grooved or perforated surface. The compactable material may be a slurry material containing magnetic particles for producing permanent magnet compacts, in which case means may be provided for maintaining a magnetic field around the die cavities.

摘要： 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.
摘要翻译： 在可压实材料中生产模制部件的机器，所述部件在设置在过滤器组件和模具盖板之间的模具板中的模腔中制造，模具腔中的可压实材料的压力导致材料的过滤和压实。 可压实材料可以是包含用于制造永磁体压块的磁性材料颗粒的浆料，在这种情况下，可以提供用于在压实过程之前和期间在模腔周围产生感应磁场的装置。
