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.

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.

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.
