Foseco's range of foundry filters are used not only in the production of castings subject to heavy wear and tear but also to safety critical parts. The application of filtration in the production of such castings enables the foundry to achieve the full potential of the mechanical and dynamic properties of the alloy chosen.
Conventional pouring systems are frequently unable to retain sufficient slag material and reaction products. Even when it is technically feasible, the design of the running system required may be inefficient and uneconomic. Correctly selected and applied, Foseco foundry filters remove inclusions and optimise running system design. Casting properties are enhanced, performance and productivity are increased, and costs are lowered.
Foundry filters also impact molten metal velocity and mould filling. A smooth, non-turbulent mould filling reduces the risk of mould erosion and oxide defects and is especially important in the casting of alloys prone to oxidation such as aluminium.
