VF Series Vacuum Furnace: Industrial Vacuum Brazing and Heat Treatment Solutions

The VF Series vacuum furnace from Normantherm is designed for manufacturers requiring precise, clean, and repeatable thermal processing. From vacuum brazing and annealing to crystallization, degassing, and heat treatment, the VF Series provides controlled processing conditions for metals, alloys, carbide, ceramics, and other advanced engineering materials.

Normantherm's VF Series includes several horizontal vacuum furnace configurations with different working-zone dimensions and load capacities, allowing manufacturers to select equipment according to component size, production volume, and process requirements.

What Is the Normantherm VF Series Vacuum Furnace?

The VF Series is a range of horizontal metallic-chamber vacuum furnaces developed for industrial thermal processing. The systems incorporate a vacuum chamber, heating chamber, vacuum pumping system, electrical control system, cooling system, and water-cooling infrastructure.

The furnaces use molybdenum-based heating elements and insulation systems designed for high-temperature vacuum processing. Depending on the model, the furnaces can reach temperatures up to 1300°C, making them suitable for a broad range of brazing and heat-treatment applications.

VF Series Vacuum Furnace Models

Normantherm offers different VF configurations to match different production requirements.

These models provide a scalable furnace platform, allowing manufacturers to select a chamber size appropriate for their component dimensions and production requirements.

VF1300-422 Vacuum Furnace

The VF1300-422 is a compact horizontal vacuum furnace designed for applications such as diamond brazing, stainless steel brazing, titanium alloy brazing, hard-alloy brazing, PCD tool brazing, annealing, crystallization, and degassing.

It has an effective working zone of 400 × 200 × 200 mm and a rated load capacity of 60 kg. The furnace has a maximum temperature of 1300°C, operating temperature of 1200°C, ±1°C temperature-control accuracy, and specified temperature uniformity of ±5°C.

This makes the VF1300-422 particularly suitable for precision components, tooling applications, R&D production, and manufacturers that require a relatively compact industrial vacuum furnace.

VF1300-644 Vacuum Furnace

The VF1300-644 provides a larger 600 × 400 × 400 mm effective working zone and a rated load capacity of 200 kg. Its front-and-rear auxiliary heating configuration is designed to improve temperature distribution throughout the working chamber.

The furnace reaches a maximum temperature of 1300°C and uses PID intelligent temperature control with ±1°C control accuracy and a specified temperature field of ±5°C under the manufacturer's test conditions.

This configuration is well suited to medium-scale production involving vacuum brazing, annealing, crystallization, and degassing.

VF1300-966 and VF1300-1288 for Larger Components

For manufacturers processing larger assemblies or higher production loads, the VF1300-966 and VF1300-1288 provide significantly larger working spaces.

The VF1300-1288 has a 1200 × 800 × 800 mm effective heating area and is designed for advanced industrial processes including vacuum brazing of stainless steel, titanium alloys, high-temperature alloys, and dissimilar metals. It can also be used for annealing, degassing, and heat treatment of aerospace, medical, automotive, and precision-tool components.

The VF1300-1288 is specified with a maximum temperature of 1300°C, ±1°C temperature-control accuracy, ±5°C temperature uniformity under specified test conditions, and a high-capacity vacuum pumping system.

Applications of VF Series Vacuum Furnaces

The VF Series is suitable for a wide range of advanced manufacturing processes.

• Vacuum Brazing

VF Series furnaces can be used for brazing tungsten carbide, stainless steel, titanium alloys, copper, diamond tools, PCD tools, ceramics, and dissimilar metals. The controlled vacuum atmosphere helps minimize oxidation and contamination during brazing.

• Heat Treatment and Annealing

The controlled thermal environment makes the VF Series suitable for annealing and heat treatment processes designed to modify material properties, relieve internal stresses, and improve material performance.

• Degassing and Crystallization

The furnaces can also support degassing and crystallization processes where controlled temperature and vacuum conditions are important for achieving the required material characteristics.

Why Choose a VF Series Vacuum Furnace?

A major advantage of the VF Series is its combination of high vacuum, precise temperature control, and uniform heating. These characteristics are particularly important when processing components made from dissimilar materials or when production quality must remain consistent across multiple batches.

The vacuum environment reduces oxidation and contamination, while controlled heating and cooling help reduce thermal stress and dimensional distortion.

For industrial manufacturers, this can translate into more consistent brazed joints, cleaner component surfaces, improved process repeatability, and better control over production quality.
