1. Design Philosophy: From "Generalization" to "Specialization and Fusion"
Future design philosophies will no longer view the hinge-type cubic press as a static, single product, but will instead tailor the equipment to the synthesis needs of different superhard materials.
Structural Optimization for Usage Frequency (Application of Forged Beams): For the synthesis of fine powder, ultra-fine powder, and RVD single crystals (sawing-grade diamonds), the synthesis time is short and usage frequency is high (approximately 5 times that of medium-coarse grit), placing extremely high demands on the fatigue strength of the hinge beams,.
    Design Trend: The future may see a return to the forged hinge beam design concept (similar to early American designs) to solve the problem of casting beams fracturing under frequent alternating stress. As forging technology advances, the cost is expected to become acceptable.
    Auxiliary Tools: Design software will shift from simple finite element optimization to more powerful software (such as Solidworks Simulation) to focus on frequency, fatigue, and non-linear analysis to adapt to high-frequency operating conditions.
"Hybrid" Design Incorporating Two-Die Technology: To break through the limitations of the traditional cubic press, future designs will absorb the strengths of two-die (belt press) technology.
    Expanding Cavity and Pressure: It may be possible to transplant the multi-layer annular mold structure of two-die presses to solve the limitation of carbide anvil diameters, or equip the press with 6-8 anvil devices to achieve higher pressure synthesis.
    Optimizing Temperature and Pressure Fields: By achieving a cylindrical cavity structure similar to two-die presses, ideal pressure and temperature fields can be created for synthesizing high-grade diamond single crystals and composite sheets, while maintaining the lower cost advantage of the cubic press.
2. Control Technology: From "Traditional Monitoring" to "Intelligent Fuzzy Control"
As materials (such as diamond composite sheets) transform from solid to melt under high temperature and pressure, causing non-linear changes in resistance and temperature, traditional electrical control systems can no longer meet high stability requirements,.
High-Precision Electro-Hydraulic Collaborative Control: Future control systems will achieve closer coordination between hydraulics and electronics, technically adopting more electro-hydraulic proportional control, hydraulic servo technology, and field bus technology.
    Objective: To achieve multi-curve, multi-functional process control for each step to adapt to complex synthesis craft requirements.
Intelligence and Fuzzy Control: To cope with complex phase change processes within the cavity, control systems will introduce intelligent fuzzy control technology.
    Dynamic Compensation: This system can rapidly capture temperature fluctuations caused by material phase changes (volume changes, resistance changes) and perform intelligent monitoring and compensation, thereby ensuring the stability of the synthesized sample.
