Foundry Bomaksan

None of the process owners in a foundry wants dust in its molds. The main reason for this is that the dust melts on the surface, causing poor surface quality. Unwanted and uncollected dust makes it difficult to bind recycled sand and additives such as resin. In order for this sand and resin to bond, dust must be removed from the system.
