Product Overview of HPHT Cubic Press Machine

The HPHT Cubic Press Machine, also known as six-face hydraulic press, is the core high-temperature high-pressure equipment to synthesize superhard materials including industrial diamond, lab-grown diamond, cubic boron nitride (CBN) and superhard cutting tools.

Shanghai Cronus independently develops two complete series of HPHT Cubic Press Machine: cast type and welded-forged type. The cylinder diameter covers full range Φ420mm to Φ1500mm, matching small, medium and large production lines with different output capacity and investment budgets.

All HPHT Cubic Press Machine adopt unified design pressure 110MPa and rated working pressure 95MPa. We provide a full 5-year warranty for all units running under pressure ≤90MPa. Stable pressure output and uniform high-temperature field support stable mass production of superhard materials, widely adopted by diamond factories, new material research labs and tool manufacturers worldwide.

Besides standard models GY420, GY560, GY650, GY800, GY950, GY1200, GY1500, welded-forged upgraded versions GY650D, GY850D, GY950D, GY1000D, GY1100D, we also supply customized models GY460, GY500, GY700, GY750, GY1050.

Upgraded Advantages of Welded-Forged HPHT Cubic Press Machine

Compared with traditional cast cubic press machine, our welded-forged HPHT Cubic Press Machine upgrades overall structure, manufacturing process and service life to cut long-term production cost for clients.

Finite element simulation and intelligent force verification form a more scientific whole frame structure. Segmented full forging plus surfacing connection technology greatly lifts integral structural strength. Exclusive overall heat treatment for hinge beams optimizes comprehensive mechanical performance including fatigue strength, yield strength and tensile strength.

The integrated structure of working cylinder and hinge beam makes the whole machine compact with low running noise, fitting compact factory layout. Under extreme HPHT working conditions, the welded-forged cubic press generates tiny and even deformation, delivering consistent pressure field during crystal growth. It effectively raises single furnace output, extends machine service cycle and reduces maintenance expense, bringing higher production efficiency and better profit ratio.

Our welded-forged HPHT Cubic Press Machine has been applied in authoritative institutes including Yanshan University High Pressure Research Center, Southern University of Science and Technology and Chongqing Chengxuan New Materials. All test indicators outperform conventional cast steel cubic press machines and lead the large-cavity HPHT equipment market.
