Super-Hard Material Cubic Hydraulic Press
Super-hard Material Cubic Hydraulic Press is a special equipment that offering pressure and temperature needed for synthesis of super-hard material, which produces ultra-high pressure through hydraulic system and high temperature through high-power current.
Brief Introduction：
The Super-hard Material Cubic Hydraulic Press is specialized equipment that provides the pressure and temperature necessary for synthesizing super-hard materials. It generates ultra-high pressure through its hydraulic system and high temperatures through a high-power electric current. Our company's Super-hard Material Cubic Hydraulic Press is developed based on independent innovation and possesses completely independent intellectual property rights. Currently, over 90% of synthetic monocrystal diamond production in China utilizes this equipment. Our press can create an ultra-high pressure and temperature environment of 4 to 6 GPa and up to 2000°C within a 100 cm³ area of the cell. It is the specialized equipment widely used for producing super-hard materials, researching high-pressure physics, advanced materials, and geophysics.
Technical features：
The press's geometric center in the three-dimensional space receives stress from six directions through the die of the carbide tungsten anvil. Simplifying the structure of the carbide tungsten anvil could decrease costs.
Six cylinders, hinged and secured by a hinge-beam, exhibit high strength and hardness.
The press is designed using 3D technology. The main stressed parts have been calculated and optimized through the Finite Element Method, ensuring a highly safe and reasonable mechanical structure.
Hinge-beams are made of integral alloy steel, refined by casting, and undergo a special heat treatment process, providing high strength and reliability.
The cylinders are forged from electroslag remelting steel, ensuring stable operation under high-pressure conditions and extending the equipment's lifespan.
Special equipment is used for numerical control processing on key parts, ensuring good interchangeability and centralized operation, allowing for synchronized work.
The hydraulic system incorporates a high-precision pressure transducer. The pressure control system uses frequency conversion technology and a proportional flow control valve to precisely manage the loading and unloading curve.
Ultra-high pressure is achievable using a booster or ultra-high pressure pump group, maintaining stable pressure over extended periods.
A high-precision displacement transducer is employed to accurately control the piston's working state, ensuring machine reliability and safety under high-pressure conditions.
High-precision power control technology is utilized in the heating system to precisely manage heating power.
Temperature direct measuring technology is used to timely measure the temperature within the cell, which acts as a feedback signal to accurately control the cell's temperature.
The press features temperature measuring technology for the anvil's pressure surface, a water coolant temperature and flow control system, and a hydraulic oil state control system, all contributing to the hydraulic press's increased operational reliability and repeatability.
Advantage of integrally forged cubic hydraulic press：
The hinge-beam blooms for the integrally forged cubic press are forged using the largest tonnage open die forging hydraulic press in China. This process results in a more compact material structure with increased strength after forging.
With the working cylinders and hinge-beams combined into a single unit, the structure of the main machine is more compact and lighter in weight.
The structure boasts ease of installation, a long service life, lower maintenance costs, and higher cost-effectiveness.
