● Helps to reduce the turbulence of metal flow and improve the temperature distribution throughout the mold volume.

● Filter the molten metal and decrease in non-metallic inclusions and oxide films in the liquid metal. 

● Improve mechanical quality of aluminum casting product.

● Improve the hardness of aluminum casting product with more average surface hard and bending strength. 

Comparing to other filter bags, it does not affect the component of aluminum alloy, and with good filtration effect, high temperature resistance, high strength, excellent acid and alkali resistance, non-stick aluminum, non-slagging, non-peeling, as well as easy installation.

Use Instructions:

● The closer the placement position is to the casting cavity, the better effect is, the better reducing the probability of secondary oxidation. The location where the casting filter is usually placed in the gating system: the lower end of sprue, the runner, the inner runner, and the sprue cup. 

● The design of the gating system should be simple, and other slag blocking measures may not be considered, which can improve the utilization rate of the sand mold and the yield of the process. 

● The aluminium pouring speed cannot be controlled with an fiberglass filter bag. 

● The working area of fiberglass filter diversion bag should be 4 times to 6 times to the blocking section of the pouring system to ensure that the pouring speed is not affected. 

● Select the corresponding filtration products according to the type of casting alloy and pouring temperature, and it should not be used at excessive temperature. 

● Select the filter screen with the appropriate aperture to truly achieve the filtering effect.

Stock Size:

● Usually 6"x 5" x 13" with mesh opening 2.5mmx2.5mm is used for Aluminum Ingots & Billets & slabs & casting plates.
