Glass fiber foundry filters manufactured by Asian Foundry Filters are fumeless and odorless. They are used for filtering impurities such as dross, slag, refractory particles, and non-metallic inclusions, from molten metals and their alloys such as aluminium, zinc, tin, lead, and magnesium. Asian Foundry Filters' glass fiber filters are suitable for gravity die-casting, sand-mould casting, investment casting, low-pressure die-casting, and shell-mould casting.
