Six-Column Hydraulic Press
The six-ram hydraulic press is an essential core equipment in the superhard materials industry. By synchronously applying pressure from six directions, it creates a stable, controllable high-temperature and high-pressure synthesis environment within the machine chamber. Primarily used for synthesizing artificial diamonds, cubic boron nitride (cBN), and other superhard materials, it serves as the primary industrial asset for superhard material manufacturers. The TB-650 model, with its proven structural design, consistent pressure output, and cost-effectiveness, has become the preferred choice for numerous superhard material production enterprises. This equipment is not only suitable for powder catalyst-based diamond synthesis but also widely applicable in special ceramics and new material research fields.
Product Details
Based on rigorous industrial standards, TB-650 demonstrates exceptional performance metrics:
Powerful Drive System: Features a 650 mm working cylinder diameter with a maximum design pressure of 110MPa. Single-cylinder thrust reaches 36,000 kN; with six cylinders operating synchronously, total pressure can reach up to 216,000 kN (approximately 2.16 million tons), meeting the requirements for large-cavity synthesis processes.
Dual-Stage Pressure Control: The equipment features a precision hydraulic system supporting 15.5 MPa high-pressure operation and 97 MPa ultra-high-pressure mode. This dual-stage design ensures seamless transition between rapid low-pressure advance and high-pressure holding phases, enhancing production efficiency while maintaining pressure stability during synthesis.
Efficient compression ratio: Featuring a 6.25:1 optimal compression ratio and 40 KVA electric heating power (adjustable per requirements), it achieves high energy conversion efficiency and effectively reduces energy costs per unit.
Spacious operating area: The piston has a maximum stroke of 90 mm, with an opening height of 421 mm and a closed height of 331 mm. This design facilitates the replacement of top hammers and adjustment of synthesis blocks, while also accommodating top hammers ranging from Φ142 to Φ160 mm, ensuring high adaptability.
Structural Features and Advantages:
High-Strength Body Structure: Our 6-side top machine is cast from premium alloy steel and undergoes precise aging treatment to eliminate internal stress. Its unique hinge beam design ensures rigidity under extreme reaction forces, minimizing deformation and extending mold life.
Precise Synchronization: Under the control system, six hydraulic cylinders achieve high-precision synchronized motion to ensure uniform pressure distribution within the synthesis chamber, significantly improving diamond quality and yield.
Use Cases:
Synthesis and production of synthetic diamond single crystals and polycrystalline diamonds.
Manufacturing of Cubic Boron Nitride (CBN).
Sintering of high-grade carbide.
R&D and prototyping of various new ultra-hard composite materials.
