Integrated Heating & Pressure System
The furnace integrates a hydraulic press system and heating chamber. It features a German-made pressure sensor with 0.001-level accuracy and a high-precision displacement sensor with ±10 μm resolution to ensure precise control. An independent pressure compensation system guarantees consistent and stable pressure during operation.
Sealed Ram Design
Adopts a professional-grade dynamic sealing structure to ensure zero leakage during long-term ram movements.
High-Performance Ram Material
The ram is available in isostatic graphite or TZM alloy to suit various high-temperature applications.
Exceptional Flatness
The ram surface flatness is controlled within ±5 μm, ensuring uniform pressure distribution.
Optimized Pressure Field Simulation
3D finite element analysis is applied to model deformation under pressure loading, ensuring the ram maintains its shape at high temperatures. Post-calculation thickness reserves guarantee stable flatness across the loading platform.
Multifunctional Ram Setup
The ram module is designed for easy assembly and disassembly. When the pressing function is not needed, the furnace can operate solely as a vacuum brazing system.
Efficient Cooling System
Equipped with a 2-15 bar inert gas rapid cooling system for external circulation, ensuring fast and uniform cooling of the workpiece.
