China NVPT Type Vacuum Tempering Furnace - High-Quality Suppliers and Factory for Metal Heat Treatment
01
Characteristics
Heat the workpiece under different vacuum degree (10-2~10-6 mbar), prevent oxidation and decarbonization, ensure the surface of the workpiece is smooth, and ensure that the internal performance of the material is not interfered by external impurities.
Graphite heater or high resistance alloy heating element, fast heating speed, high temperature resistance, long life, with high efficiency insulation layer design, significantly reduce energy consumption, effectively shorten the tempering cycle, improve production efficiency.
Adopt multi-zone independent temperature control system, combined with PID algorithm, the furnace temperature uniformity can reach ±5℃, ensure the uniform change of material microstructure, avoid performance differences.
Equipped with built-in convection heating function to achieve efficient transmission and uniform distribution of heat, so that the equipment can operate stably in the low temperature area, accurately regulate the temperature, and meet the diversified process needs.
Equipped with advanced internal cooling system, no additional cooling treatment is required, which can directly and safely enter the subsequent operation process, greatly improving production efficiency.
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.
The opening mode of the furnace door is flexible (such as rotary type, vertical lifting type), which can be perfectly adapted to the automatic production line and effectively improve the overall production efficiency of the equipment.

Frequently Asked Questions
What range of vacuum degree can these tempering furnaces support?
The furnaces can heat workpieces under different vacuum degrees ranging from 10-2 to 10-6 mbar (with 10-1~10-6 mbar optional as working vacuum). This range effectively prevents oxidation and decarbonization to ensure a smooth surface finish.
What is the temperature uniformity of the NVPT series?
By adopting a multi-zone independent temperature control system combined with a PID algorithm, the furnace temperature uniformity can reach ±5℃, ensuring uniform structural changes in the material.
What are the differences between NVPT-600 and NVPT-1000 models?
The NVPT-600 has an effective working area of 600×600×1000 mm, handles up to 600 kg, and has an installed power of 130 KW. The NVPT-1000 has a larger working area of 800×800×1300 mm, handles up to 1000 kg, and operates with 180 KW of power.
Can the technical specifications be customized?
Yes. We support custom configurations for the furnace's effective working area size, maximum temperature, working vacuum level, and other specific parameters tailored to your production scenarios.
How does the cooling system improve process efficiency?
The equipment is built with an advanced internal cooling system. This removes the need for extra external cooling steps, allowing workpieces to safely and directly proceed to the next production stages.
