Are you a professional manufacturer of large diameter aluminum ingot and billet, rectangular aluminium slab, and aluminum-alloy casting parts? 

If yes, you must be familiar with Fiberglass thermally fused shunt combo bag.

It is weaved by special high-twist & high-strength alkali-free fiberglass yarn, special post-treatment, coated with phenolic resin and suitable "carbonized" by high temperature.

Applications:

● Used in sand casting, permanent mold, shell mold, draw mold and investment casting.

● Apply to filter and evenly distribute molten aluminum in molds.

● Apply to filter large diameter aluminum ingot and billet, rectangular aluminium slab, and aluminum-alloy casting parts.

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. 

● 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.

Common-use size/stock size: 6"x 5"x 13"

There are following advantages of Fiberglass thermally fused shunt combo bag:

● New environmental protection material, does not burn during whole use process , no harm to human body. 

● Advanced production equipment, warp and weft standard for base cloth, high temperature resistant coating mesh uniform, the finished product is exquisitely made without burrs.

● Both sides of the bag adopt square hole fixing device technology, more convenient operation and improve the working rate.

Common use size is 6" x 5" x13", but all dimensions can be customized for you only according to your pictures, samples and drawings.
