A New Compact Approach to Electromagnetic Pulse Crimping

The BONNE EMPT-MINI is a compact electromagnetic pulse crimping machine designed for high-performance metal joining in automotive wire harnesses, power connections, and other demanding electrical applications.

Using high-energy electromagnetic forces, EMPT-MINI enables solid-state joining of copper or aluminum conductors to compatible terminals without conventional thermal welding. Its non-contact electromagnetic forming process applies energy directly to the workpiece, helping reduce mechanical damage to terminal surfaces and minimize heat-related effects associated with conventional thermal joining processes.

With a maximum energy output of 25 kJ and a rated processing capacity of 50–240 mm², EMPT-MINI provides a solution for large-section wire harnesses, tubular terminals, and selected sheet-to-sheet joining applications.

As BONNE’s compact electromagnetic pulse crimping solution, EMPT-MINI brings this technology into a smaller equipment format for manufacturers seeking alternative metal-joining processes.

Key Advantages of EMPT-MINI

1. Compact Electromagnetic Pulse Technology

EMPT-MINI integrates electromagnetic pulse crimping technology into a compact machine platform, offering manufacturers a space-conscious solution for demanding metal-joining applications.

2. High-Energy Processing for Large Cross-Sections

With a maximum energy output of 25 kJ, the system is designed for processing copper and aluminum wires with cross-sectional areas of 50–240 mm², subject to terminal geometry and process conditions.

3. Non-Thermal Joining Process

The electromagnetic pulse process uses high-energy electromagnetic forces rather than conventional resistance heating or arc-based joining. This helps minimize thermal effects on the workpiece and supports applications where heat-related deformation must be controlled.

4. Suitable for Copper and Aluminum Conductors

EMPT-MINI supports joining applications involving copper or aluminum conductors and compatible terminals. It can also be evaluated for dissimilar-metal combinations, depending on material compatibility and joint design.

5. Adaptability to Complex Terminal Geometries

The process can accommodate selected three-dimensional metal components, including formed terminals and irregular busbar geometries, subject to tooling design and process validation.

6. Process Control for Consistent Production

Controlled energy delivery supports repeatable processing when machine settings, tooling, materials, and workpiece positioning are properly established and validated.

Scope of Application

The BONNE EMPT-MINI is designed for the following metal-joining applications:

• Wire-to-Terminal Joining: Copper or aluminum wires with cross-sectional areas of 50–240 mm² joined to tubular terminals, with terminal thickness up to 5 mm.
• Sheet-to-Sheet Joining: Joining of compatible metal sheets, subject to workpiece specifications and process validation.

Application suitability depends on material, dimensions, terminal geometry, and process conditions.
