HPHT Cubic Press Machine for Lab-Grown Diamond Production

An HPHT diamond-making machine uses high pressure and high temperature
to create the conditions required for diamond crystal growth. During production, a carbon
source such as graphite is placed inside the cubic press and exposed to controlled pressure
and heat. This process reproduces the environment in which natural diamonds form beneath
the Earth’s surface.

Our HPHT cubic press system is designed with automated controls and a practical operating
interface. Depending on the project requirements, the equipment can be used to produce
gem-quality lab-grown diamonds, industrial diamonds, PDC cutters and other superhard materials.
