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:
- Good thermal conductivity: due to its high thermal conductivity, the melting time can be shorten to save energy and time
- High strength
- High thermal resistance
- High chemical resistance
- Excellent thermal shock resistance
- Low thermal expansion
- Good lubrication properties
- Dimensional accuracy
- Outstanding surface quality
- Low ASH content so that melting metal cannot be polluted during melting and casting process


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.
