Haoyue supports documentation aligned to the agreed process window.

Process Flow

Diffusion Bonding Process Overview

Vacuum diffusion bonding joins mating surfaces through atomic diffusion under heat and sustained pressure, without a melting interface.

D5H joint-specific review

Turn furnace capacity into a joint and inspection acceptance plan.

Use this product page for the D5H equipment configuration. The final proposal should be tied to the material pair, complete joint stack, tooling, load distribution, thermal-vacuum records, and inspection route.

Joint and stack definition

Provide material grades, plate or channel drawings, bonding area, stack height, surface route, flatness, protected passages, and fixture envelope.

Load and thermal field

Confirm platen or ram arrangement, tooling stiffness, alignment, temperature measurement, pressure or load trace, dwell, and controlled cooling.

Vacuum and records

Define the vacuum and cleanliness requirement, measurement points, leak-rate method, data channels, report format, and retained process records.

Inspection and handover

Assign witness samples, dimensional or leak checks, joint validation, factory test, documentation, installation, training, and site acceptance responsibilities.

Can the chamber be customized?

Yes. Chamber size, heating zone, fixture, pressure, and atmosphere configuration should be confirmed through technical review.

Is a process test recommended?

For new materials or demanding density targets, a sample process discussion helps reduce equipment selection risk.

What should be sent with an inquiry?

Material, target temperature, pressure or load, atmosphere, workpiece size, and expected capacity are the most useful inputs.

Diffusion Bonding

D2 Vacuum Diffusion Welding Furnace

Diffusion welding refers to a solid-state welding method in which workpieces are pressed under high temperature without visible deformation or relative movement. This process is particularly suitable for joining dissimilar metal materials, heat-resistant alloys, ceramics, intermetallic compounds, composite materials, and other new materials. Especially for materials that are difficult to weld using fusion welding methods, diffusion welding has obvious advantages.
