China VBL Bottom Charging Vertical Vacuum Furnace - High-Performance Heat Treatment Equipment from Reliable Suppliers & Factory

Bottom lift loading system with vertical furnace, reduces floor space, supports heavy workpieces efficient loading and unloading, and reduces manual operation intensity.

Heating the workpiece under different vacuum degrees (10^-2 to 10^-6 mbar) to avoid surface oxidation and decarbonization, ensuring a pure and stable process environment.

Multi-zone independent temperature control, combined with PID algorithm, to achieve ±5℃ furnace temperature uniformity with high temperature control accuracy, meeting the needs of large workpiece consistency processing.

The heating chamber is made of graphite composite material or all-metal structure (such as molybdenum heating elements and metal heat insulation screen), which is highly resistant to high temperatures and high-pressure airflow, ensuring a long service life.

Through different cooling inert gases (nitrogen, argon, helium) and under different cooling pressures, combined with a high-speed and large-flow fan to quickly cool the workpiece, the cooling speed is fully controllable.

The load-bearing table of the processing parts can be rotated during heating and cooling, which ensures the best temperature uniformity and effectively controls the deformation of the parts.

Enhanced furnace structure combined with multiple safety protections, in line with international safety standards, ensuring an equipment life of more than 20 years.

Integrated PLC, featuring a program controller or computer interface, touch screen, recorder, and real-time monitoring of furnace vacuum degree, temperature, pressure, and other data, supporting remote fault diagnosis and process tracing.
