SIVEX FC foam filters are produced in our modern, state-of-the-art production facility in accordance with DIN ISO 9001:2000 and VDA 6.1. Stratified samples of SIVEX FC foam filters are subjected to a direct impingement test to verify thermal stabi-lity. Aluminium is poured from a height of 450 mm directly on to the SIVEX FC filter face. This is a much tougher environment than that experienced in normal foundry applications and therefore ensures the filters are capable of performing well in the field. In addition to this, dimensional accuracy, pore size distribution and weight control is also checked against specification.

This applies especially for aluminium castings employed in automotive engineering where weight reduction is of growing importance. Safety critical components, such as aluminium alloy wheels and chassis components, demand a close adherence to high quality standards in terms of mechanical properties.

		can be safely remelted in the return material as no contaminating elements go into solution
		can be removed from the melt surface easily due to it’s comparable low density
		is machineable

Our Application Engineers have extensive process knowledge and many years of experience, and are well placed to offer customers advice on running and gating system design, as well as optimum filter selection and placement.
