Aluminium filtration fiberglass mesh filter Ningxin Fiberglass mesh filter for molten aluminium filtration are specially designed and woven for the diffusion and filtration of aluminium.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 construction in high density. The production facility is ISO 9001 approved and tests are run on each batch for loss on ignition, rigidity, and hole size. FEATURES & BENEFITS1.Brings down the casting rejection rate due to slag inclusions to less than 3%.2.Cheap and cost effective,easy installation.3.Compared to galvanized metal mesh, it will not change molten metal composition. 4.Stay away from molten aluminium and easy to handle the aluminum scrap recycling (Fibeglass mesh can float on top of the molten metal when the metal is recycled and can be scooped out), this can greatly reduce cost.                5.Reduces molten metal turbulence,improves molten metal distribution and flow.                 6.Produces minimal odor and smoke. 7.Remove oxides and inclusions to improve castings mechanical properties and surface finish.8.Excellent stiffness and toughness,good impact resistance.9.Mesh and grid is well organized and highly integrity MAIN APPLICATION: Automobile or motorcycle wheel rims,aluminum cylinder,aluminium pistons,rods,ingots,aluminum and alloy precision castings.
