Hot press furnaces are used worldwide for vacuum hot pressing, diffusion bonding, hot forging and powder densification. Over 12 feet, more than 2,000 tons of hydraulic pressure has been built from the MINI 5ton press R&D size, production system workspace. In the hot zone of graphite or refractory metals, the hot press operates at temperatures up to 2400 C, while the welding chamber permits high vacuum performance in the range of 10 - 6.
It is one of the few manufacturers of vacuum furnace hot press that designed, engineered and manufactured the frame and vacuum chamber of the press. Strong boxed H-frame structure and corner braces provide welded rigid frames that are reinforced and machined to reliably maintain internal parallel to 0.002 planes. Vacuum chambers often have leak growth rates of less than 5 mu/h, and adhere to the norms allowing confidence to provide the industry's only standard five-year room warranty.
In addition to various sizes and pressing capabilities, customers can have complete control of the force, pressure, position and movement of the hydraulic press head. The state-of-the-art electronic equipment enables pressure or full scale internal force control of less than 0.025% and 0.001"position resolution. All pressures, forces and distances are fully integrated in the furnace system with temperature, vacuum and gas conditions through data acquisition and control systems. User-programmable formulations enable precise synchronization with the movement and force of the push rod, including position or pressure slope, and maintain furnace conditions. Manual point control function can be conveniently set up and pre-loaded and operated. Safety interlocking alerts operators and protects overtemperature in case of chip breakage in furnace system.
It is to build a custom hot-press furnace to meet the unique process requirements of customers, including multiple rams, special gas atmosphere, including hydrogen or oxygen, rapid cooling requirements, customized temperature control and at the same time control in the industry is unique, skilled, and semi-continuous furnace system and vacuum interlock, integrated die and mould transmission system, automatic filling die part and injection system.
