Customized shaped porous graphite ingot molds have an indispensable role in the production of all kinds of gold and silver jewelry, due to its stable chemical properties, good thermal shock performance, excellent performance of thermal conductivity and thermal conductivity performance (determines the speed of solidification of the metal or alloy),  also the good self-lubricating performance, not only get the perfect jewelry precise processing dimension, smooth surface, but also improves the casting speed. 

This graphite ingot mold not only greatly improves the rate of qualified products, but also reduces the rate of wear, so that the quality of finished products greatly improved.
