Fiberglass Combo Shunt Filtration Bag For Aluminium Casting

Fiberglass Filtration & Shunt Combo bag is weaved by special high-twist & high-strength alkali-free fiberglass, special post-treatment, coated with special resin and "carbonized" by high temperature.

Application: Apply to filter and evenly distribute molten aluminum in molds.

Let's take a look at the general use principles as follows:

● 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.
