Haoyue designs and manufactures vacuum diffusion bonding furnaces for solid-state joining of metals, titanium assemblies, plate and microchannel heat exchangers, and other precision stacks. Equipment configuration begins with the material pair, channel or joint geometry, surface preparation, load path, temperature-pressure cycle, vacuum package, tooling interface, chamber size, inspection method, and project acceptance plan. Published equipment references do not replace material-specific bonding trials or joint validation.
Selection factors
Joint, channel, and material pair
Document the material pair, surface finish, coating or interlayer, joint and channel geometry, stack height, thickness, and thermal expansion considerations.
Load path and tooling
Define compressive load, flatness, fixture stiffness, alignment, stroke, and how the load reaches the complete bonded stack.
Vacuum and atmosphere
Confirm vacuum level, leak-rate expectations, purge gas, contamination limits, and whether a protective atmosphere is needed during cooling.
Inspection and records
Agree on dimensional checks, leak checks, bond inspection, witness samples, data logging, and acceptance documentation before quotation.
