Why use TF Combo Bags during aluminum casting

Why use TF Combo Bags during aluminum casting?

TF Combo Bag is weaved by special high-twist & high-strength alkali-free fiberglass yarn, special post-treatment, coated with resin and carbonized by high temperature. its withstand temperature up to 1000 °C.

Advantages:

● Easy to install,

● Remove oxides,

● Reduce turbulence,

● Reduce waste products,

● Improve metal distribution,

● The coated bags will produce light gas and less smoke when in contact with aluminum liquid.

Applications:

● 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.

● Used in sand casting, permanent mold, shell mold, draw mold and investment casting, which can remove impurities, reduce turbulence, eliminate air bubbles, thereby improve casting quality and reduce production costs.

Purposes of using the bags:

1. The aluminum liquid is divided to two ends of ingot through the bags, this process will determines the temperature distribution around crystallizer device. And the metallographic structure of the cured aluminum alloy ingot will be affected by the temperature distribution. 

2. The second purpose is to keep and leave the oxide in the bag, reduce the aluminium liquid flow and filter out all the large particles that mainly include alumina, chloride and titanium, boron, magnesium oxide and large resistant material shed.

3. Improve the temperature distribution of molten metal and control flow of aluminium vertical direct.

4. Improve working environment, bags will be producing very little smoke, fumes or flame when molten aluminium flow inside, but it is harmless, no any affect to staff.

Features of our bags:

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

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

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

Certificates of our TF Combo Bag:

We, Hebei CangChen, a professional manufacturer of such bags with ISO certificate, and our bags have been certified by MSDS(USA). We have exported the bags with our own registered trademark"CANGENDAS" to many coubtries, as well as with OEM service.
