High-Performance VBL Bottom Charging Vertical Vacuum Furnace from China Suppliers and Factory for Heat Treatment
characteristic 01
Bottom lift loading system with vertical furnace, reduce floor space, support heavy workpieces efficient loading and unloading, reduce manual operation intensity
Heating the workpiece under different vacuum degree (10-2~10-6 mbar) to avoid surface oxidation and decarbonization and ensure pure and stable process environment
Multi-zone independent temperature control, combined with PID algorithm, to achieve ±5℃ furnace temperature uniformity, with good temperature control accuracy, to meet 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 resistant to high temperature and high pressure airflow and has long service life
Through different cooling inert gas (nitrogen, argon, helium) and under different cooling pressure, combined with high speed and large flow fan to quickly cool the workpiece, cooling speed is controllable
The load bearing table of the processing parts can be rotated during heating and cooling, which can ensure the best temperature uniformity and effectively control the deformation of the parts
Enhanced furnace structure + multiple safety protection, in line with international safety standards, equipment life of more than 20 years
Integrated PLC, with program controller or computer interface, touch screen, recorder and other real-time monitoring furnace vacuum degree, temperature, pressure and other data, support remote fault diagnosis and process tracing

Frequently Asked Questions FAQ
The bottom lift loading system with a vertical furnace reduces the required floor space, facilitates efficient loading and unloading of heavy workpieces, and significantly reduces manual operation intensity.
By heating the workpieces under a high vacuum range of 10-2 to 10-6 mbar, the system effectively prevents surface oxidation and decarbonization, ensuring a pure and stable process environment.
The furnace achieves a temperature uniformity of ±5℃. This is accomplished through multi-zone independent temperature control combined with an advanced PID algorithm, ensuring consistent processing for large workpieces.
Yes. By utilizing different cooling inert gases (such as nitrogen, argon, or helium) under varying cooling pressures, and combining them with a high-speed, large-flow fan, the cooling speed is fully controllable.
The table can rotate during both the heating and cooling stages to ensure the best possible temperature uniformity across the parts, which effectively controls and minimizes workpiece deformation.
Yes, we support customization for the effective working area size, maximum temperature, working vacuum level, gas cooling pressure, and other parameters to match your specific production requirements.
