摘要： A filter for filtering a liquid metal and to be received in a mold housing defined by internal side and face walls. The filter has a top wall and side walls extending downwardly from the top wall, the side walls being joined together at respective corners. The side walls extend downwardly towards distal end portions. The corners of the filter have a stiffness or rigidity that is higher that the remainder of the filter for increasing the strength of the overall filter and for helping the filter to maintain its shape and integrity throughout casting. The shape of the side walls allows an easy and consistent placement of the filter in the mold housing and ensures that the filter is maintained in place.

摘要： Filtration devices are provided with original structural features to allow a better stiffness of the same and prevent the possibility of being distorted and/or driven under the pressure of a flux of liquid metal or an alloy thereof which is passing there through. Said features may consist of a ridge portion extending the periphery of a filtration device, a rim portion provided in double-basket filtration devices, or a particular > shape filtration device.
