Non-metallic inclusions (flaws caused by impurities) in a casting are one of the most widespread causes of casting defects. They adversely effect surface finish, mechanical properties, machining characteristics and pressure tightness - and can lead to a casting being scrapped. Foseco has led the industry in removing impurities, reducing turbulence and providing rapid and consistent metal flow through its development of filtration systems.

These filtration systems (case studies) remove inclusions, reduce turbulence and provide rapid and consistent flow. We are the largest supplier of foundry filters in the world, with the widest choice of foam and cellular filters for aluminium, copper, iron and steel casting applications.

Our application engineering teams draw on the widest experience in the world to help customers with filter selection and optimisation of filter gating system designs.
