Product Descriptions
High Pressure High Temperature (HPHT)High Pressure High Temperature (HPHT) is a way in which synthetic diamonds are manufactured. HPHT uses what are called “presses” in order to recreate the environment inside of the Earth.、
Cubic presses use a cube-shaped volume. It uses multiple anvils to put pressure on the volume. Originally only four anvils were used, however, cubic presses now use six anvils because it maximizes the pressure available. Cubic presses are smaller than belt presses, HPHT is the most commonly used system for producing synthetic diamonds, mainly because of its low cost.
