Project Introduction: Haifei Four-Column Aluminum Diffusion Welder for Multi-Layer Aluminum Plate Welding

Aug 10,2026

Traditional welding & hot pressing equipment fail to control pressure and temperature precisely for multi-layer aluminum plates, causing interlayer gaps, poor adhesion, deformation and wrinkles, which lead to unstable conductivity, local overheating and delamination cracking. Haifei four-column aluminum diffusion welder realizes solder-free diffusion bonding for multi-layer aluminum sheets.

I Customer Background & Production Pain Points

The manufacturer produces conductive accessories for energy storage cabinets and photovoltaic inverters.

Original process problems:

1.Uneven hot pressing force creates internal micro-gaps, resulting in overheating during operation;

2.Excessive temperature melts aluminum while insufficient heat causes inadequate atomic diffusion & easy delamination after bending;

3.No pressure holding forming structure, inconsistent plate thickness.

II Customer Requirements

1.Optimize pressure distribution to eliminate interlayer gaps and realize full tight lamination;

2.Stabilize hot-pressing temperature & holding time to boost interlayer bonding strength for aluminum diffusion;

3.Optimize pressure slow-release forming process to reduce deformation, wrinkles and surface melting.

III Custom R&D Solutions

The R&D team adjusted parameters repeatedly to solve multi-layer aluminum welding difficulties:

1.Process Verification: Batch tests on aluminum plates of various layers, thicknesses & widths;

2.Equipment Selection: Haifei four-column diffusion welder with even pressure to achieve tight lamination and reduce plate deformation;

3.Structural Design: Smooth pressing plates with uniform surface temperature distribution;

4.Core Advantages

Uniform Stress: Tight interlayer contact

Stable Conductivity: Steady contact resistance, reliable performance

Perfect Forming: Flat sheets, low deformation

IV Delivery & After-sales Feedback

Pre-acceptance and inspection finished. Continuous trial runs maintain stable yield. All original production issues solved after commissioning. Customers praise timely, thoughtful after-sales support.
