The heyu mesh belt brazing furnace is a continuous heat-treatment line that carries aluminum components through preheating, brazing, and cooling zones on a heat-resistant alloy mesh belt, all under a protective high-purity nitrogen atmosphere. Workpieces stay in their fixtures from load to unload, so deformation is controlled and dimensional accuracy holds across the run. The CAB process uses non-corrosive flux, which means no post-weld pickling is required and the brazed joints come out dense, bright, and uniform. The line is the standard production route for aluminum plate-fin heat exchangers, condensers, evaporators, intercoolers, and battery cooling plates, where throughput and joint consistency decide line economics.
We build both standard and non-standard mesh belt brazing lines around your part footprint and cycle rate, and we can pair this continuous line with our batch vacuum brazing cells so that high-volume parts run on the belt while low-volume or tricky assemblies run in the vacuum cell. Custom sample development takes about 30 days, and we share production progress with photos and videos during build. Once the line is tuned, parts exit at a steady belt pitch rather than in batch lots, so furnace operators supervise a continuous flow instead of loading and unloading separate baskets, and daily output scales directly with belt speed.

Application Fields
Automotive radiators and condensers
Continuous belt flow under N2 gives every tube-to-fin joint the same thermal cycle, which is what lets radiator lines guarantee zero leakage across millions of units per year.
Battery cooling plates and cold plates
Non-corrosive CAB flux leaves no residue inside internal coolant channels, a requirement that vacuum or salt-bath brazing cannot meet as cost-effectively at volume.
HVAC evaporators and intercoolers
Fixtured loading on the mesh belt keeps thin fins upright through braze, so heat-transfer density stays uniform across the core.
Customization
Belt width, furnace length, zone temperatures, atmosphere flow, belt speed, and loading fixture interface are all customized to your part and production rate. We build standard and non-standard lines and offer sample runs.
Packaging & Transportation
We support EXW and FOB. The line is packed according to international export requirements based on the nature of the actual goods.
