China VBL Bottom Charging Vertical Vacuum Furnace - High Performance Heat Treatment Equipment from Leading Suppliers & Factory
Characteristics
01Bottom 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
03What are the advantages of the bottom lift loading system?
The bottom lift loading system with a vertical furnace configuration significantly reduces required floor space. It supports the efficient and secure loading and unloading of heavy workpieces while reducing manual operation intensity.
What vacuum levels can these furnaces achieve?
The VBL series supports a working vacuum range of 10-1 to 10-6 mbar (optional). Heating under these vacuum degrees prevents surface oxidation and decarbonization, ensuring a pure and stable process environment.
How is temperature uniformity controlled for large workpieces?
The furnace utilizes multi-zone independent temperature control combined with a PID algorithm to achieve a temperature uniformity of ±5℃. Additionally, the load-bearing table can rotate during heating and cooling to ensure optimized uniformity.
What cooling media and pressures are supported?
The system supports inert cooling gases including Nitrogen and Argon (with Helium options) under cooling pressures ranging from 0.87 to 10 bar abs. Combined with high-speed, large-flow fans, the cooling speed is fully controllable.
Can the specifications of the VBL series be customized?
Yes. We support custom adjustments for the effective working area size, maximum temperature limits, working vacuum levels, gas cooling pressure, and other parameters tailored to your specific production scenarios.
