Pyrotek Rigid Glasweve™ filters for low-pressure casting are an innovative industry development that allow aluminium foundries to recycle excess sprue return aluminium without negative impact on aluminium quality or outside treatment. This can result in significant cost savings and process efficiency.
In the low-pressure casting process, a sealed holding furnace is pressurized (up to 1 atmosphere) above the molten aluminium surface. This pressure causes the aluminium to rise steadily up the stalk tube, pass through a filter in the sprue bushing before
