The size of the filter is determined based on the pouring speed and pouring weight.
When choosing degassing unit, we must consider the following aspects
Casting material/pouring temperature/pouring head height/pouring volume/pouring time
In order to ensure the filtering effect of the filter, the placement of the filter and the design of the gating system should also follow certain specifications.
The installation of the filter must be placed as close as possible to the casting to obtain the maximum filtration efficiency and flow adjustment.
Considering practical factors, such as the position that can be placed in the mold and the design of the gating system, the filter is often placed in the runner.
Sometimes the filter is placed at the bottom of the sprue, but this is not recommended.
Because the filtering effect and flow... less
