Product Description

When melts are melting, casting and molding in very high temperature ranges, the requirements of graphite components rise on material quality, material purity, product design, working lifetime and cost-efficiency. Our graphite melting crucibles, graphite casting crucibles, graphite continuous casting dies are the ideal solution for melting and casting precious metals, copper alloy, and cast-iron products. Our isostatic graphite is used in the metal-casting process and allows the metal processing to be monitored continuously through various stages of melting from the liquid state to the solid state resulting in semi-finished products such as wires, bars, tubes, and strips. Our graphite dies can be used in vertical, horizontal and up-casting.

We apply high purity, high strength, high density graphite materials, equipped with excellent engineers, experts and high precision CNC production equipment to supply our clients with high quality graphite melting crucible, graphite casting crucible, graphite ingot molds, graphite dies and molds for tube, plate, wire.

Advantages:

1. Good thermal conductivity: due to its high thermal conductivity, the melting time can be shorten to save energy and time
2. High strength
3. High thermal resistance
4. High chemical resistance
5. Excellent thermal shock resistance
6. Low thermal expansion
7. Good lubrication properties
8. Dimensional accuracy
9. Outstanding surface quality
10. Low ASH content so that melting metal cannot be polluted during melting and casting process

Why does graphite matieral suitable for smelting and casting for jewelry industry and other industry? 
The crucible is made from high quality graphite which makes the graphite crucible to have a good thermal conductivity, resistant to acidity and alkalinity and a high temperature resistance, therefore, ensuring quality of products.

Graphite crucibles do not contaminate molten metals because the graphite material is fused and does not loosen. The quality of a graphite crucible is determined by how it is manufactured, which influences its structure, density, porosity, and strength.

As the graphite has an excellent heat performance, the time spent on melting is short, therefore saving energy.Their excellent heat performance helps in melting metals quickly for faster production cycles.
