01 / Equipment Overview
Six directions. One precisely controlled reaction cell.
A cubic hydraulic press creates a stable high-pressure, high-temperature environment by driving six opposed anvils toward the center of a cubic sample assembly.
Hydraulic power supplies the compressive load. A high-current circuit then heats the internal reaction cell while sensors, intensifiers and the control system coordinate pressure, temperature, dwell and decompression. The large usable volume makes the equipment suitable for both repeatable industrial synthesis and research that cannot be performed in smaller diamond-anvil cells.
Cubic compression
Six anvils converge along X, Y and Z axes to confine the sample assembly uniformly.
Resistance heating
High current passes through the cell heater to generate and hold the target temperature.
Controlled release
Programmed pressure and cooling profiles protect the product and tooling after synthesis.
02 / Working Principle
From hydraulic force to a calibrated HPHT environment
The exact pressure-temperature relationship is established through tooling design, cell calibration and process recipes, not hydraulic pressure alone.
- 01
Prepare the cell
Powder, catalyst, heater, insulation and pressure medium are assembled to the validated recipe.
- 02
Load symmetrically
Six cylinders advance under synchronized control until the programmed hydraulic pressure is reached.
- 03
Heat under pressure
High current raises cell temperature while the control system maintains load and process stability.
- 04
Dwell, cool and unload
The material is held for transformation, cooled under pressure, then decompressed at a controlled rate.
03 / Engineered Advantages
Built around strength, repeatability and service life
Configurations are engineered to the process, cell size, output target and local utility conditions. Final values are confirmed in the technical proposal.
Structural integrity
Cast or forged-welded hinge beams

110 MPa design pressure
Main-machine design pressure supports demanding HPHT duty; routine operating limits are defined for each delivered configuration.
Compact integrated structure
Working cylinders and hinge beams form a rigid, space-efficient body with reduced operating noise.
Process-level control
Pressure, dwell, heating and decompression recipes can be configured for repeatable production.
Inspection before delivery
Material testing, ultrasonic inspection, hardness checks, metrology and trial operation are built into acceptance.
Broad model range
Cast and forged-welded platforms cover laboratory development through high-volume industrial synthesis.

Questions engineers ask before specifying a cubic press
Send us your target material, cell dimensions, pressure-temperature profile and planned annual output for a model-specific evaluation.
What is a six-sided cubic hydraulic press?
It is a large-volume high-pressure apparatus that uses six opposed anvils to compress a cubic reaction assembly from three orthogonal axes. It can generate HPHT conditions for material synthesis and physical research.
What pressure and temperature can the working chamber reach?
Depending on cell design, pressure medium, tooling and calibration, systems can be configured for working-chamber conditions up to approximately 6 GPa and 2000°C. Hydraulic pressure and chamber pressure are different values.
How does the machine generate heat?
A high-current power system passes current through a resistive heater inside the reaction cell. Temperature is controlled through a validated power curve and, where applicable, thermocouple feedback.
Which products can be synthesized?
Typical products include industrial diamond, lab-grown diamond, CBN, PDC and PCBN compacts. The platform is also used for functional materials, semiconductor research and geoscience experiments.
What is the difference between cast and forged-welded structures?
Cast frames are proven, economical platforms across a broad size range. Forged-welded structures can offer improved material consistency, fatigue strength and deformation control for demanding long-cycle service.
How is pressure uniformity controlled?
Uniformity depends on cylinder synchronization, anvil geometry, guide accuracy, cell assembly consistency and calibration. The hydraulic and control systems are tuned together during commissioning.
Can each cylinder be controlled independently?
True triaxial research configurations can use independent high-precision control for all six cylinders, enabling synchronous or asynchronous loading, confining pressure and differential stress paths.
What information is required for model selection?
Please provide the target material, cell size, pressure and temperature, dwell time, batch rate, planned output, available utilities, floor constraints and local compliance requirements.
What utilities are normally required?
A typical system requires three-phase electrical power, cooling water, hydraulic oil management, ventilation, foundation capacity and safe material-handling access. Exact loads are model dependent.
What safety systems are included?
Available measures include mechanical guarding, pressure and temperature interlocks, over-pressure protection, emergency stop circuits, controlled decompression and restricted-access operating zones.
Do you provide installation and training overseas?
Yes. The project scope can include foundation guidance, installation supervision, commissioning, trial production, operator training, preventive maintenance planning and remote support.
Are electric, diesel or mobile configurations available?
The cubic press itself is normally an electrically powered fixed installation. For Cronus crushing and biomass product lines, electric-motor, diesel-engine and mobile wood-chipper configurations can be customized separately.
