Aerospace & Defence


The quality of alloy castings is routinely enhanced by the use of metal pouring filters positioned within the gating system of the mould. These filters remove non-metallic inclusions such as furnace and ladle slag, moulding sand, refractories and de-oxidation products suspended in the metal stream. They also ensure a smooth metal flow into the mould. Correct use of these filters can reduce internal re-work costs in welding and cleaning, improve casting yields and machinability and hence machine tool life.

Mantec's Puremet Metal Pour Filters are extensively utilised in the investment casting of high performance directionally solidified and single crystal gas turbine engine components both for aerospace and industrial applications.

In a related application, ceramic cores are used in the investment casting of high performance gas turbine engine components for aerospace engines. It is critical that these cores offer stability at high casting temperatures, no adverse core-to-alloy reactions, and dimensional consistency. It is for this reason that the use of Mantec's Bullers™ Rings is a critical part of the core manufacturers' Quality Assurance procedures.


Mantec's filtration products have been used for several decades on board warships for applications such as breathing air filtration, bilge water filtration and fuel filtration. The filters for breathing air generally comprise a coalescing pre-filter (nominally 10 microns), a carbon adsorber and an after-filter (nominally 0.3 microns), whereas the bilge and fuel filtration systems are based on Mantec's Star-Sep™ Ceramic Membrane technology.
