40 Ton 400x400mm Vacuum Hot Press with Independent Temperature and Pressure Control

Product Overview

This system is a precision vacuum hot press engineered for high-pressure, high-temperature material consolidation in a controlled environment. With a maximum force of 40 tons over a 400×400 mm platen area and vacuum capability down to -0.1 MPa, it delivers exceptional parallelism and pressure uniformity. The integrated heating and vacuum chamber enable advanced processing of air-sensitive materials that require contamination-free conditions.

Ideal for research laboratories and pilot production, this equipment is widely used in battery electrode densification, solid-state electrolyte lamination, ceramic composite sintering, and polymer molding. Its ability to independently program temperature rise and hydraulic loading ensures that materials are subjected to compression only at optimal thermal states, preventing early-stage shear damage.

Engineered for durability, the 600 kg rigid closed-loop frame limits elastic deformation to micron levels, even under full load. Paired with industrial-grade 380V balanced heating, thermal barriers, and a polished stainless steel vacuum chamber, this unit guarantees long-term repeatability and safe operation in demanding, round-the-clock environments.

Key Features

• Rigid Four-Column Load Frame: The massive 600 kg welded structure employs a closed-loop design that counteracts the 400 kN reaction force, maintaining platen parallelism within tight tolerances and ensuring micron-level frame deflection for uniform pressure distribution across the entire 400×400 mm area.
• Symmetrical Matrix Heating: A 5.5 kW heating system with 380V 3-phase power distributes heating elements in a uniform matrix across the platens, minimizing thermal gradients and hot spots—critical for achieving consistent part quality in temperature-sensitive processes.
• High-Vacuum Stainless Steel Chamber: Fabricated from thick-walled SUS304 stainless steel with mirror-polished internal surfaces, the chamber is leak-tested using pressure and helium mass spectrometry, providing a static vacuum down to -0.1 MPa to evacuate volatiles and prevent oxidation.
• Dual Gas Port with Micro-Adjustment: After evacuation, controlled flows of N₂ or Ar can be introduced via precision metering valves, creating a protective inert atmosphere for sensitive materials such as lithium compounds or high-temperature alloys.
• Independent Temperature-Pressure Profiling: Operators can decouple thermal ramps from hydraulic loading, programming temperature setpoints before initiating compression; this prevents premature shear stress on materials at their softening or phase-transition points, enhancing densification uniformity.
• Integrated Water Cooling Circuits: Built-in straight-through cooling channels in the platens allow rapid heat dissipation upon cycle completion; this not only shortens turn-around time but also protects heating elements from long-term drift due to excessive thermal soak.
• Thermal Isolation Barriers: Insulator plates positioned between the heated platens and the hydraulic actuator protect seals and components from sustained high temperatures, extending service intervals and ensuring reliable actuation.
• Industrial Electrical Integration: The system requires a 380V 50Hz 3-phase supply, recommended 16A breaker, and proper grounding; it is designed for robust industrial environments with compliance to standard electrical codes.
