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.
A filter for filtering a liquid metal and to be received in a mold housing defined by internal side and face walls, the filter comprising a top wall and first, second, third and fourth side walls extending downwardly from the top wall, the first, second, third and fourth side walls being joined together at respective first, second, third and fourth corners, wherein, in use, the top wall is adapted to receive the liquid metal and the first, second, third and fourth side walls are adapted to at least partially contact respective first, second, third and fourth internal side walls of the mold housing in which the filter is received.
A filter for filtering a liquid metal and to be received in a mold housing defined by internal side and face walls, the filter comprising a top wall and first, second, third and fourth side walls extending downwardly from the top wall, the first, second, third and fourth side walls being joined together at respective first, second, third and fourth corners, the first, second, third and fourth side walls extending downwardly towards first, second, third and fourth distal end portions, wherein the filter is made of a rigidified fabric of heat resistant fibers or threads of heat resistant fibers, and wherein the top wall and the first, second, third and fourth side walls have a first stiffness and wherein at least one of the first, second, third and fourth corners has a second stiffness, the second stiffness being higher than the first stiffness.
