1. Core Application Areas The application of the hinge-type cubic press has expanded beyond diamond manufacturing into various sub-sectors of superhard materials:
High-End Diamond Single Crystal Synthesis: The equipment is used to synthesize gem-grade large single crystals, plate-shaped large single crystals for tool processing, and industrial large single crystals with diameters exceeding 3mm.
Sawing-Grade Diamond Manufacturing: It is widely used to synthesize diamond single crystals of various grit sizes, covering medium-coarse, fine, and ultra-fine materials to meet different sawing needs.
Core Components for Energy Drilling Tools: In coal fields, natural gas extraction, and oil drilling, the equipment is used to synthesize Polycrystalline Diamond (PCD) compacts, which are core components of various high-performance drill bits.
Precision Machining Tool Materials: It can be used to synthesize woodworking PCD cutters, as well as CBN (Cubic Boron Nitride) and PCBN cutters used to replace traditional cemented carbide tools in metal processing.
Frontier New Material Synthesis: Its applications have extended to special material fields, such as the synthesis of rare earth metals and optoelectronic materials.

2. Functional Adaptability and Technical Deepening To meet the rigorous synthesis conditions of different materials, the hinge-type cubic press has demonstrated strong targeted functional evolution:
Long-Time Pressure Retention for "Large Single Crystals": The core challenge in synthesizing large single crystals (>3mm) is the need for ultra-long pressure retention. Traditional plunger intensifiers are limited by their stroke and cannot meet this requirement, so the equipment needs to be equipped with stroke-limit-free ultra-high pressure oil pumps or reciprocating intensifiers to provide continuous and stable synthesis conditions.
High-Frequency Fatigue Resistance for "Fine Particles": When synthesizing fine and ultra-fine diamond grits, the single synthesis time is extremely short (only 1/7 of that for medium-coarse grits), meaning the equipment usage frequency is very high (about 5 times higher). This high-frequency operation can easily lead to fatigue fracture of the hinge beam. Therefore, for such applications, the design needs to introduce the third and fourth strength theories and favor forged hinge beams to improve fatigue strength.
Dynamic Temperature Control for "Composite Sheets": Unlike single crystal synthesis, the synthesis process of diamond composite sheets (PCD) involves a phase change from solid to melt within the chamber, causing drastic changes in heating resistance. This requires the equipment's electrical control system to have extremely high sensitivity to quickly compensate for voltage changes, ensuring the stability of the synthesis quality.
