Technical Specifications & Customization Options

Giant Vacuum Aluminum Brazing Furnace

Advanced Heating Chamber & Thermal Insulation System

The heating chamber utilizes a high-performance composite insulation structure, integrating nickel-chromium (Ni-Cr) alloy heating elements with multi-layer 1Cr18Ni9Ti reflective shields (AISI 321 stainless steel equivalent). This engineered design ensures exceptional temperature uniformity, minimal heat loss, and optimal energy efficiency throughout the brazing cycle.

Three-Stage High Vacuum System

Equipped with a robust three-stage high vacuum pumping system comprising:

1. Diffusion pump (primary high vacuum)

2. Roots booster pump (intermediate stage)

3. Mechanical backing pump (roughing stage)

This configuration achieves ultra-high vacuum levels critical for flux-free aluminum brazing, ensuring superior joint quality and preventing oxidation.

Standard & Optional Configurations

– All models operate as negative pressure furnaces (standard design)

– External forced air circulation cooling system available as optional add-on per customer specifications

Customizable Work Zone Dimensions

Effective working area and chamber dimensions are fully customizable to accommodate specific production requirements and component geometries.
