Filter Modeling
Filters are generally used in the foundry industry to improve casting cleanliness and to reduce the cost of casting manufacture.
Proper design of filters is a task which can be done in SUTCAST using the filter tool of the software.
Filters, when applied correctly (Filter/Choke area ratio, the size and the number of filters and location and position of ceramic filter), can be relied on to lock in particles before they can go into the casting cavity. The use of filter in gating system can reduce defects but a designed gating system specifically to incorporate filter will be more effective.
