Introduction
Vacuum stainless steel chamber brazing furnace, a versatile solution for vacuum brazing of low-melting point materials such as aluminum alloys, as well as for low-temperature sintering and heat treatment.
Key Features
● Utilizes stainless steel metal furnace and electric heating alloy tube, achieving a maximum temperature of 750℃.
● Heating with annular-shaped electric heating alloy tubes ensures high temperature uniformity within ±5℃.
● User-friendly interface featuring a high-definition touch screen with built-in operating system.
● Equipped with PLC automatic control system for precise operation.
● Clean stainless steel furnace design, paired with mechanical pump + diffusion pump vacuum unit, achieving an ultimate vacuum level of 7x10-3pa (no load, cold state).
● Offers cost-effective performance compared to molybdenum foil vacuum furnaces, with low power consumption and competitive pricing, making it an ideal choice for low-temperature brazing applications.
Optional Accessories
● External rapid cooling system, capable of reducing temperature from brazing levels to 180 degrees in less than 1 hour.
● Chiller unit for temperature control.
● Stainless steel multi-layer material rack for convenient placement of multiple brazing workpieces.
● Low-temperature aluminum zinc-based flux for enhanced brazing processes.
