high pure graphite boat for jewelry casting
Dear friend please read the following carefully.
We have our own factory. Comparing to trading companies, we can guarantee the products' quality. Our products' price is also very competitive because we don't have intermediate links.
Our products include graphite rods, blocks and all kinds of graphite crucibles, molds, etc. We use pitch coke to produce graphite crucible and blocks, with no petrol coke added, ensuring the high density, high purity and high strength of our products. Whereas in order to cut the cost, many Chinese companies mix petrol coke with pitchcoke to produce graphite rods, reducing the graphite products’ strength and their resistance to oxidation, acid,and alkali. A second differentiator from our competition is that we produce the graphite rods and blocks that we use to manufacture our products, giving us full control of the quality of our product.
Here are the images for actual pitch coke product(This is our product):
Graphite crucibles made of pitch coke have much higher density. After being polished,the surface of the product is shiny and smooth. Whereas petrol coke graphite crucibles' surface is rough,and also has many tiny holes.
Here are the images for actual petrol coke product(other company's products):
Our Company Graphite mold Advantages:
1 .Great thermal stability
2.Great corrosion resistence,impact resistence and acid alkali-resistence.
3.Great thermal conductivity, which can shorten the melting time and save energy.
4.Less than 300 ppm ash content helps to avoid contaminating the metal.
5.High purity of graphite reduces the chance of metal sticking to the crucible, making our crucibles last longer.
