Product Overview
The HFTD-200-Y Copper Diffusion Bonding Machine is designed for diffusion welding of conductive metal parts such as copper busbars, copper bars, copper-nickel connectors, and laminated copper foil flexible connectors. It is suitable for new energy, power equipment, energy storage systems, low-voltage electrical products, and copper busbar processing.
This model features a maximum primary current of 300A, 100% rated duty cycle, 10.4V secondary voltage, and 150L/min cooling water consumption, making it suitable for copper welding applications that require stable continuous operation and consistent welding quality.
For customers, a copper diffusion welding machine is not only about whether the copper parts can be joined. More important questions are whether the welded joint can maintain stable conductivity, whether multi-layer materials are fully bonded, whether batch production remains consistent, and whether the part will overheat during long-term current transmission.
The HFTD-200-Y is better suited for medium- to high-load copper conductive parts, especially projects that require long operating hours, stable mass production, and a reliable welding process window.
If your product involves copper busbars, laminated copper foil connectors, copper-nickel composite parts, or new energy conductive components, you can send us drawings, material thickness, weld area, and testing requirements. Haifei can evaluate the machine configuration and welding solution based on your actual workpiece.
Key Product Features
100% Duty Cycle for Continuous Production
The HFTD-200-Y has a 100% rated duty cycle, making it more suitable for longer continuous operation than machines designed mainly for intermittent welding. For batch orders in new energy, energy storage, and power connection applications, equipment stability directly affects delivery efficiency and rework rates.
Suitable for Copper Busbars and High-Current Conductive Parts
Copper busbars and copper bars are commonly used for power transmission and battery connections. They require stable contact area, welding strength, and electrical reliability. If the welded area is not fully bonded, contact resistance may increase, causing local overheating or reduced long-term reliability.
Suitable for Laminated Copper Foil Flexible Connectors
The HFTD-200-Y can be used for diffusion welding of laminated copper foil connectors. Through controlled heat input and pressure, it helps create more stable interlayer bonding in the welded area. It is suitable for battery module flexible connectors, energy storage flexible connectors, and flexible conductive parts.
Supports Copper-Nickel Composite Conductive Parts
The HFTD-200-Y can be matched to copper-nickel material combinations, thicknesses, weld areas, and strength requirements. It helps reduce weak bonding, uneven joining, and performance variation in dissimilar metal welding.
Typical Application Fields
New Energy Battery Connectors
Suitable for copper busbars, laminated copper foil connectors, copper-nickel connecting sheets, and conductive connectors in battery modules. For high-current connection areas, welding quality directly affects electrical stability, temperature rise, and long-term safety.
Conductive Parts for Energy Storage Systems
Energy storage systems commonly use copper busbars, flexible connectors, current-collecting conductive parts, and copper-nickel composite connectors. The HFTD-200-Y is suitable for these conductive components that require stable batch production, helping reduce poor contact and local overheating risks.
Power Equipment and Busbar Processing
Suitable for copper busbars, copper bars, and copper flexible connectors used in distribution cabinets, busbar systems, switchgear, and power connection parts. For copper components carrying current over long periods, a stable welded contact surface helps improve operating reliability.
Low-Voltage Electrical Components
The machine can be used for copper terminals, copper connecting sheets, contact connectors, and copper alloy parts in low-voltage electrical products. Fixtures can be matched according to product size and weld position to improve positioning stability and batch consistency.
Laminated Copper Foil Flexible Connector Manufacturing
Suitable for multi-layer copper foil flexible connectors, flexible conductive sheets, battery flexible connectors, and current-collecting flexible connectors. With stable pressure and heat input control, it helps improve interlayer bonding quality and reduce weak bonding, delamination, and appearance variation.
What Problems Can the HFTD-200-Y Help Solve?
From Sample Welding to Stable Mass Production
Many copper welding projects can achieve acceptable results during sample testing, but problems appear during mass production, such as strength variation, inconsistent appearance, or unstable conductivity test results. The HFTD-200-Y is more suitable for production environments that require long-term stable output and repeatable welding processes.
Reducing Weak Bonding Between Copper Foil Layers
When welding laminated copper foil, improper pressure, temperature, or welding time may cause insufficient bonding between internal layers. The machine can adjust parameters according to foil layer count, thickness, and weld area to improve interlayer bonding quality.
Improving Overheating Risks in Conductive Parts
The welding quality of copper busbars and flexible connectors affects contact resistance. If the welded area is unevenly bonded, local overheating may occur during long-term current transmission. Diffusion welding helps form a more stable contact surface. Final electrical performance should be confirmed through contact resistance, temperature-rise, or current-carrying tests.
Supporting Different Copper Part Projects
Whether the product is a copper busbar, laminated copper foil connector, copper-nickel sheet, or special-shaped conductive component, the welding area, pressing direction, positioning reference, and loading method should be evaluated according to the actual structure. Haifei can match the equipment and tooling solution based on the customer's product.
FAQ Copper Diffusion Bonding Machine
Q1. What copper parts is the HFTD-200-Y suitable for?
A: The HFTD-200-Y is mainly suitable for copper busbars, copper bars, copper-nickel connectors, laminated copper foil flexible connectors, and other conductive copper parts. It is commonly used in new energy, power equipment, and energy storage applications.
Q2. What is the difference between the HFTD-200-Y and HFTD-150-Y?
A: The HFTD-200-Y has a maximum primary current of 300A and a 100% rated duty cycle, making it more suitable for continuous production and higher-load copper welding applications. The HFTD-150-Y is more suitable for medium-load or standard copper welding projects.
Q3. Is this machine suitable for laminated copper foil flexible connectors?
A: It can be evaluated for this application. Laminated copper foil welding depends on foil layer count, thickness, weld area, and peel strength requirements. Sample welding is recommended before final configuration.
Q4. Can it weld copper-nickel connectors?
A: Yes. It can be used for copper-nickel connector welding. Since copper and nickel have different material properties, process testing is recommended according to material thickness, weld area, and electrical requirements.
Q5. How can electrical performance after welding be confirmed?
A: Electrical performance can be confirmed through contact resistance testing, temperature-rise testing, or current-carrying tests. The machine provides stable welding conditions, but final results should be verified based on the customer's actual workpiece and testing standard.
