New Generation of Fiberglass Fabric Mesh Filter For Aluminium Low Pressure Die Castings Filtration

Galvanized steel or iron wire mesh filters are at present commonly used for low pressure die castings filtration, especially for aluminum alloy wheels. The wire mesh filters are cost effective, with good strength and flexible on shapes and sizes. Now there is a new and better material to
perfectly replace it due to the wire mesh filter has disadvantages. Using the wire mesh filter, there will be largely Fe element added to the aluminum castings and this will lower the castings mechanical strength, especially for high quality standard, this means critical. For risers containing wire mesh filters after solidification, it can not remelted directly to furnace, even after the treatment. The direct cost is the risers had to be sold as scrap. It's great waste.

To use the fiberglass mesh filter to replace the traditional wire mesh filter, Sprue recycle now easier, COST REDUCTION GREATLY.

Fiberglass mesh filters for aluminum filtration are specially designed and woven for the diffusion and filtration of molten aluminum. High twisted yarns are used to control strand diameters and resist flattening or distortion under pressure from contact with molten metal. The integrity of the
weave pattern is maintained by the use of phenolic resin, and by the use of leno or Plain construction in high density. Regular coating and carbonized treatment are both available. Fiberglass fabric 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.
