High-Temperature Electric Resistance Continuous Copper Brazing Furnace for Auto Parts

A brazing furnace is a professional high-temperature thermal processing equipment designed for precision metal brazing. Different from traditional welding, it melts only the brazing filler metal while keeping the base metal solid. Under vacuum or protective atmosphere, the molten brazing material penetrates the workpiece gaps through capillary action, forming smooth, high-strength, oxidation-free joints after cooling. It is ideal equipment for bright and high-precision mass brazing of metal components in refrigeration, automotive, hardware and tool industries.

The complete brazing process adopts a standard three-stage continuous treatment to ensure stable brazing quality:

1. Degreasing & Preheating – Remove surface oil, dust and cutting residues at low temperature to avoid pores, virtual welding and welding defects.

2. High-temperature Brazing – Heat evenly to the melting point of the brazing filler. The liquid brazing material fully infiltrates the welding gaps to form tight and uniform joints.

3. Controlled Cooling – Cool gradually under protective atmosphere to prevent oxidation, discoloration and thermal deformation, ensuring bright surface and consistent welding strength.

1.Bright Welding Effect – Supports nitrogen, hydrogen and cracked ammonia atmosphere / vacuum environment. Workpieces come out bright and clean without oxidation, blackening or secondary polishing.

2.No Deformation & High Strength – Brazing at temperature below base metal melting point ensures original workpiece hardness, size accuracy and firm welding seams.

3.Uniform Temperature Field – Equipped with precise PID temperature control system. Even temperature distribution guarantees stable brazing quality for every batch.

3.High Automation & High Yield – Continuous mesh belt operation realizes unmanned mass production, greatly improving production efficiency and reducing labor cost.

4.Wide Material Compatibility – Suitable for copper, stainless steel, aluminum alloy, cemented carbide and various dissimilar metal brazing.
