Electric heating vacuum brazing furnace is a large mechanical equipment used for brazing heat treatment in a vacuum environment.

Working principle

Preprocessing: Apply flux to the welding area of the cleaned and degreased workpiece.

Positioning fixation: Fix the two workpieces to be welded in position.

Heating welding: Place the workpiece into the furnace and use an electric heating system to raise the temperature to the point where the solder melts. After the solder melts, fill the weld seam and complete the welding.

Main features 

Vacuum environment: A vacuum system is used to extract extremely low pressure, almost oxygen free and pollution-free environment, to avoid the influence of gases such as oxygen and nitrogen on welding quality.

Precise temperature control: Equipped with advanced temperature control system, it can accurately set and regulate the brazing temperature to ensure welding quality.

Wide applicability: Suitable for welding various metal materials, including aluminum, aluminum alloys, copper, copper alloys, stainless steel, alloy steel, low-carbon steel, titanium, nickel, and Inconel.

Efficient and energy-saving: The electric heating system has a high energy utilization rate, and welding in a vacuum environment can reduce the discharge of exhaust gas and wastewater, which is in line with the development trend of green manufacturing.

Application area 

Aerospace: Used to manufacture components for aircraft and rockets, ensuring high quality and reliability of the components.

Electronic industry: used in the manufacturing of semiconductor devices, LEDs and other electronic devices to improve product reliability and stability.

Automotive manufacturing: used to produce key components such as engines and transmission systems, improving the manufacturing efficiency and quality of automotive parts.

Other fields, such as medical devices, high-end electronics, engineering machinery, etc., also have extensive applications.

Type

Single chamber horizontal vacuum brazing furnace: It has the advantages of high purity, precise temperature control, wide applicability, and low production cost.

Hot fireplace and cold fireplace: Two types of stoves can be heated by natural gas or electric heating, and can be designed as side mounted stoves, bottom mounted stoves, or top mounted stoves (kang type) structures.
