High Purity Without Impurities: The graphite content of Taeantech high-purity graphite mold is as high as 99.99% or more, and the content of impurities (such as silicon, iron, calcium, etc.) is extremely low, ensuring that the gold and silver bars will not be contaminated during the casting process, thereby ensuring the purity and quality of the gold and silver bars.
Uniform Thermal Conductivity: The graphite mold has extremely high thermal conductivity and can quickly and evenly conduct heat to ensure that the temperature distribution of gold and silver bars is consistent during the casting process, avoiding deformation or cracks caused by local overheating or uneven cooling.
Cost Saving: Taeantech high-purity graphite mold can still maintain structural stability at high temperatures (for example, above 1700°C), is not easy to break or deform, and is suitable for long-term high-temperature casting. This thermal stability can reduce the loss of the mold, extend its service life, and reduce production costs.
Lubricity: High-purity graphite molds have natural self-lubricity and a low friction coefficient. Gold and silver bars are not easy to stick or scratch when demolding, ensuring a smooth surface of the finished product. The low friction coefficient reduces the wear between the mold and the gold and silver bars, further extending the service life of the mold.
Environmental Protection: Graphite itself is non-toxic and harmless. No harmful substances will be produced during the melting and casting process of gold bars, which meets environmental protection requirements. The used graphite mold can be removed through high-temperature treatment to achieve reuse and reduce resource waste.
