Vacuum Diffusion Welding Furnace

Description
Vacuum diffusion welding furnace is mainly suitable for pressure diffusion welding process and PM pressure sintering process of materials like dissimilar alloy, ceramics, metal ceramics.

Technical Features
1. The vacuum hot pressing furnace is configured with single chamber, internal heating, cold wall and horizontal structure.
2. The furnace is equipped with hydraulic press device, which ensures the system controlled loading pressure precisely.
3. The pressure method has two options: single-way pressure/double-way pressure.
4. The hot zone has two options: graphite insulation/full metal insulation.
5. The loading pressure has many options: 30T/35T/100T/200T/400T/500T/800T/1000T
6. The temperature has many options: 1500°C, 1800°C, 2000°C, 2300°C, 2500°C
7. The pressure head has two options: ISO static pressing graphite/TZM alloy.
