Placement position: The casting filter can be cut into squares of any size with scissors, placed under the sprue cup, on the lap surface of the runner, on the lap surface of the runner and the runner, and pressed with the box . If the filter screen and the slag collecting bag are used in combination, the filtering effect is better.

Principles of use

1. It can effectively remove air bubbles, ash oxides, and various assimilates and other harmless impurities in the aluminum melt, greatly improving the yield of aluminum castings, improving the quality of aluminum products, and preventing the penetration of other metal components The shortcomings of the aluminum solution do not affect the aluminum alloy factors, so as to ensure the quality of aluminum castings.

2. Improve the mechanical properties of aluminum castings: The hardness of the castings can be increased, and the contour hardness can be averaged and the bending strength of the castings can be improved.

3. Change the machinability of castings, and advance the processing yield. Compared with various types of filters, the high temperature resistant fiber filter does not affect the composition of the aluminum alloy; because the fiber itself has the effect of adsorbing impurities, the filtration effect is better. In addition, the low temperature resistant fiber filter has the same high temperature resistance and mesh shaking. Good, easy to use and other advantages, not to mention that it is not conducive to the return of waste (after the waste is returned to the furnace, the mesh floats on the surface of the aluminum solution). High temperature resistant fiber filter cloth is an ideal filter material for low-grade aluminum alloy castings.
