Asian Foundry Filters (AFF) manufactures high temperature-resistant, resin-treated, fumeless and odorless glass fiber filters for non-ferrous metal and alloy casting. Technologically advanced, these fumeless glass fiber filters are used for applications such as gravity die-casting, sand-mold casting and investment casting of molten non-ferrous metals and their alloys at high temperatures in foundries.

AFF filters are made through a specialized proprietary process that gives unparalleled flame-resistance and next to NIL volatile content, which ensures the filter does not catch flame at any temperature. This product characteristic is one among other high-tech features, which has for long been (and still is) the holy grail for foundry filter manufacturers worldwide.

AFF Foundry Filters are exported to countries such as Indonesia, Thailand, Mexico, and Japan, to the world's leading automotive component manufacturing foundries. AFF has powered the manufacture of over 300 million pistons till date.
