Product Overview
The main parts of a cubic press are usually:
- Pressure system. An array of high-power hydraulic cylinders and pistons actuated by electric pumps produce up to 1.5 million PSI of pressure - replicating the crushing forces deep inside Earth.
- Temperature control system. The press encloses the central cubic chamber in precision-controlled heating systems including resistant elements and laser emitters.
- Pressure vessel. Surrounding the core is a rigid pressure vessel architected using high-strength alloy steel. It provides an impregnable barrier for retaining the extreme temperature and pressure levels.
- Control system. Sophisticated automation technology including PLCs and PID controllers monitor and calibrate process parameters in real-time. By optimizing temperature, pressure and time configurations, they facilitate flawless manufacturing runs.HPHT Cubic Presses Powering Applications

Application of HPHT Cubic Press
HPHT cubic presses unleash extreme pressure and temperature to create novel materials breakthroughs across industries.
Diamond materials that are produced with the HPHT cubic press machine are widely used in industry, optics and medicine. GaN-on-Diamond semiconductors have emerged as a game-changer in the field of electronics, offering a remarkable set of properties that surpass traditional materials.
PCD
HPHT diamond machines are used to manufacture cutters and tools from polycrystalline diamond compacts (PDC). In these advanced systems, diamond precursors are subjected to extreme pressures in excess of 5 GPa and temperatures in excess of 1500°C to facilitate the synthesis of polycrystalline diamond composites. PCDs exhibit exceptional hardness and wear resistance, enabling faster and more economical oil and gas drilling operations.
Lab-Grown Diamonds
Advanced HPHT technology using laboratory diamond machines allows the growth of high quality diamonds that are as good as their mined counterparts. HPHT diamonds are more affordable and ethical than mined diamonds, alleviating concerns about the environmental impact of traditional mining methods.
PCBN and tools
The full name of PCBN is "polycrystalline cubic boron nitride," a superhard material synthesized through HPHT processes akin to those used for polycrystalline diamond fabrication. It is commonly employed in the production of cutting tools, punches, and other industrial components that demand exceptional hardness, thermal stability, and wear resistance. HPHT machines exert immense pressures and temperatures on precursor compounds, facilitating the phase transition and crystallization into the desired polycrystalline cubic boron nitride structure.
The application of diamond wafers produced by diamond making machines, such as HPHT cubic presses, has revolutionized various industries, including manufacturing, medicine, and electronics. These lab-grown diamond machines create diamond materials with exceptional properties that make them ideal for a wide range of industrial, medical, and electrical applications.
Industrial Applications
In the manufacturing industry, diamond wafers produced by diamond press machines have become indispensable for cutting, grinding, and polishing tools. The extreme hardness and wear resistance of diamonds make them perfect for machining tough materials like ceramics, hardened steel, and composite materials.
Application in Electronics
In the electronics industry, diamond wafers produced by HPHT cubic presses have the potential to transform the way we design and manufacture electronic devices. Diamond's wideband gap, high thermal conductivity, and excellent electrical insulation properties make it an ideal material for high-power, high-frequency, and high-temperature applications. Diamond wafers are being used to develop advanced semiconductor devices, such as power transistors and diodes, which can operate at higher voltages, currents, and temperatures than traditional silicon-based devices. This could lead to more efficient, compact, and reliable electronic systems for applications ranging from renewable energy to electric vehicles.
Diamond's unique optical and thermal properties make it suitable for use in advanced optoelectronics devices, such as high-brightness LEDs and laser diodes. By incorporating diamond materials into these devices, manufacturers can achieve higher output powers, improved heat dissipation, and longer lifetimes, enabling the development of more efficient and reliable lighting and laser systems.
How to Choose a Hydraulic Press Machine?
When selecting a cubic press, buyers must understand their production goals upfront - whether for industrial diamond powder, HPHT rough diamond growth, diamond enhancement or tool-grade diamonds. The press configuration and technical specifications can then be tailored accordingly.
For example, producing single-crystal diamonds requires precise, sustained pressure control over longer growth cycles, necessitating advanced electronics. Conversely, industrial diamond synthesis involves shorter cycles and simpler pressure parameters, lowering control panel requirements. Configuration directly impacts system pricing and return on investment.
The cubic press promises to accelerate the adoption of lab-grown diamonds globally. With heightened production volumes, improved crystal quality and lower operating costs compared to older HPHT technologies, the cubic press helps lab diamond producers meet rising market demand. As the premier HPHT solution, it will shape the future trajectory of the created diamond industry worldwide.
