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.
Functions:
● 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.
● Ensure the removal of oxides or other debris suspended in the volume.
● Remove the harmful impurities such as bubbles, ash oxides, and various inclusions in aluminum molten liquid.
● Greatly improve the yield of aluminum castings, improve the quality of aluminum products.
● Avoid the problem of other metal components into aluminum solution.
● Does not affect the composition of aluminum alloy.
● Improve the hardness of aluminum casting product with more average surface hard and bending strength.
● Ensure the quality of aluminum castings.
This bag can also improve the mechanical properties of aluminum castings, can increase the hardness of the castings, and the surface hardness is uniform and improve the bending strength of the castings.
In this way, the manufacturer can produce terminal products with assured quality.
Compared with other kinds of filters, Fiberglass Filtration Shunt Combo Bag has the advantages of low price, convenient use, no change of metal composition, good filter slag and low gas output. Shunt bags can withstand higher temperature and more suitable for high temperature precision casting production.
The Benefit of Usage of Fiberglass Filtration Shunt Combo Bag:
● The bag can withstand the liquid temperature of 700℃, it can be used continuously for 4 hours when the flow is not more than 10 kg/min, for 1.5 hours continuously when not more than 120 kg/min.
● It can ensure the removal of oxides or other debris suspended in the volume, remove the harmful impurities such as bubbles, ash oxides, and various inclusions in aluminum molten liquid, greatly improve the yield of aluminum castings, improve the quality of aluminum products, and avoid the problem of other metal components into aluminum solution, does not affect the composition of aluminum alloy, to ensure the quality of aluminum castings.
● It can also improve the mechanical properties of aluminum castings, can increase the hardness of the castings, and the surface hardness is uniform and improve the bending strength of the castings. In this way, the manufacturer can produce terminal products with assured quality.
● At the same time, the shunt bag does not pollute the liquid aluminum, does not affect the chemical properties of the metal, and the aluminium liquid can be directly remelt, thus the cost can be reduced greatly.
● It is the ideal filtration material in the process of aluminum metal smelting.
