Features： 
a .The alkali-free glass fiber filter has the advantages of high strength, good toughness and impact resistance. The product has high plasticity and can be cut at will.
b .Alkali-free glass fiber is mainly used for filtration on aluminum alloys and products whose pouring temperature is within 800 degrees.
c .Reduce defects such as pores and slag holes in castings through machine filtration. The turbulent flow effect is the best, which improves product quality and reduces the scrap rate.
d .Effectively improve the iron increase problem caused by the use of wire mesh, making the riser iron easy to recycle and reuse, and reduce the overall cost.
e .Widely used in filtration for precision casting of automobile and motorcycle wheels, pistons, steering knuckles, cylinder heads, battery packs, aluminum ingots and aluminum alloy parts.
