Product Overview
The HFVD-200-S Servo Aluminum Diffusion Welding Machine is
engineered for high-consistency welding of conductive aluminum
components, including aluminum busbars, aluminum bars, laminated
aluminum foil flexible connectors, aluminum-nickel connectors, and
copper-aluminum transition joints.
This machine utilizes a servo electric cylinder pressing system,
delivering significantly more precise pressure and displacement
control than conventional pneumatic or hydraulic solutions. It is
particularly suitable for applications requiring consistent weld
quality, controlled indentation, and superior finished-part
appearance.
As aluminum continues to replace copper in new energy, energy
storage, and electrical applications due to its weight and cost
advantages, manufacturers face challenges with oxide layers,
welding consistency, and electrical reliability. The HFVD-200-S
combines controlled pressure application with diffusion welding
technology to achieve reliable metallurgical bonding and stable
electrical performance.
If your products experience issues such as unstable contact
resistance, inconsistent weld strength, insufficient interlayer
bonding, or production variability, Haifei can provide sample
testing and process evaluation based on your specifications and
performance requirements.
Key Features
Servo Electric Cylinder Control for Precise Pressure Management
Equipped with a servo electric cylinder pressing system that
enables highly accurate control of the welding pressure profile.
For laminated aluminum foil connectors, thin aluminum busbars, and
dissimilar metal joints, stable pressure application improves
bonding uniformity and reduces quality variations caused by
pressure fluctuations. Benefits are especially noticeable in
projects where indentation depth and component deformation must be
carefully controlled.
Designed for High-Consistency Production
For manufacturers in new energy and energy storage industries,
maintaining consistent quality during mass production is critical.
The HFVD-200-S allows critical welding parameters to be stored and
recalled, minimizing operator-dependent adjustments and improving
consistency from batch to batch. This facilitates standardized
production processes for long-term manufacturing programs.
Supports Aluminum-Nickel and Copper-Aluminum Joint Development
As new energy technologies evolve, aluminum-nickel and
copper-aluminum transition joints are becoming increasingly common.
Since these materials have different thermal conductivity,
electrical conductivity, and surface characteristics, the
acceptable welding process window is often narrow. The HFVD-200-S
can be used for sample testing and process validation to determine
optimal welding parameters for specific material combinations.
Improved Weld Appearance Control
Many conductive connection components must meet both electrical
performance requirements and appearance standards. Through precise
displacement control, the HFVD-200-S helps reduce excessive
indentation, edge deformation, and localized surface damage, making
it suitable for products with demanding cosmetic requirements.

Frequently Asked Questions
What is the difference between the HFVD-200-S and a standard
aluminum diffusion welding machine?
The HFVD-200-S uses a servo electric cylinder system that provides
more precise pressure and displacement control, making it better
suited for applications requiring higher welding consistency and
appearance quality.
Can the machine weld laminated aluminum foil flexible connectors?
Yes. The achievable layer count depends on individual foil
thickness, total stack thickness, and weld area. Sample testing is
recommended for evaluation.
Is it suitable for copper-aluminum transition connectors?
Yes. Process validation can be performed based on material
combination, dimensions, and performance requirements.
How is electrical performance verified after welding?
Electrical performance is typically evaluated through contact
resistance testing, temperature-rise testing, and current-carrying
capacity testing.
Can the machine be integrated into an automated production line?
Yes. The machine supports automatic loading and unloading systems,
robotic handling, and full production line integration.
Is sample welding available before purchase?
Yes. Haifei can perform sample welding trials using
customer-provided samples and provide test results to verify
process feasibility before equipment investment.
