The HFTD-100-Q is a specialized Copper Diffusion Welding Machine designed for the high-precision manufacturing of flexible connectors and multi-layer copper foil busbars. By applying controlled temperature and pressure through a pneumatic-hydraulic system, the machine triggers atomic diffusion between copper layers. This creates a solid-state molecular bond without the use of solder or filler metals, ensuring the finished joint has the same electrical and mechanical properties as the base material.
1.Molecular-Level Bonding
Achieves a seamless joint with zero increase in electrical resistance, critical for high-voltage power applications.
2.Solder-Free Process
Eliminates the cost of consumables and the risk of flux corrosion, resulting in a cleaner and more environmentally friendly production line.
3.Pneumatic-Hydraulic Hybrid System
Provides a smooth and stable pressure output (up to 100kVA class), preventing deformation while ensuring consistent bonding across the entire joint area.
4.Preserved Material Flexibility
The localized heating control ensures that only the contact area is welded, leaving the rest of the copper foil layers perfectly flexible for installation.
1.New Energy Vehicles (EV)
Manufacturing of flexible battery pack busbars and laminated connectors.
2.Power Transformers
Joining of multi-layer copper foils for high-current transformer outlets.
3.Switchgear & Busways
Production of flexible joints for low-to-medium voltage electrical switch cabinets.
4.Induction Heating Equipment
Assembly of high-conductivity water-cooled leads and terminals.
1. Molecular-Level Bonding Integrity
The joint is not just a connection; it becomes a single piece of metal. It maintains 100% of the original conductivity of the copper, with zero increased resistance at the weld zone.
2. Specialized Pneumatic-Hydraulic Hybrid System
It provides constant and uniform pressure during the entire heating and cooling cycle. This prevents "over-squeezing" or thickness inconsistency, ensuring every flexible busbar meets strict tolerance standards.
3. High-Precision Temperature & Time Control
This precision prevents the "annealing" of the non-welded part of the copper foils, preserving the maximum flexibility of the busbar while ensuring a solid bond at the head.
4. Consumable-Free & Eco-Friendly Production
It significantly reduces the cost per part and eliminates hazardous fumes or flux residues. The result is a clean, bright joint that requires zero post-weld cleaning or grinding.
5. Industry-Specific Customization
Whether you are welding 0.05mm copper foil or 40mm thick laminated busbars, our equipment is pre-programmed with optimized recipes based on years of industrial field data.
Q: Does the HFTD-100-Q require any protective gas like Argon?
A: For standard copper-to-copper diffusion welding, the high-pressure contact area creates a natural seal. However, for specific high-purity requirements, the machine can be configured for specialized atmospheres.
Q: What is the maximum thickness of copper foil it can handle?
A: It is designed to bond stacks of foils ranging from 0.05mm to 0.5mm thick, up to a total combined thickness of approximately 35mm-40mm.
Q: Is the operation difficult for new workers?
A: Not at all. The PLC system stores multiple welding recipes. Once the parameters (Pressure, Temp, Time) are set, the operator only needs to load the workpiece and press the start button.
