The EMPT-MINI Electromagnetic Pulse Equipment delivers state-of-the-art non-contact crimping and cold welding technology designed for high-voltage electrical interconnects. By utilizing electromagnetic force directly onto the workpiece, EMPT-MINI achieves high-strength, high-conductivity joints without mechanical die wear or surface deformation.

Engineered specifically for heavy-duty automotive wire harnesses and power distribution components, EMPT-MINI provides an ideal solid-state joining solution for copper-to-copper, aluminum-to-aluminum, and copper-to-aluminum dissimilar metal applications.

Why Choose EMPT for EV High Voltage Busbars?

Key Features & Process Advantages

• Non-Contact Processing (Zero Damage): Electromagnetic force acts directly on the terminal. Amplitude and force focus precisely at the center of the joint with zero mechanical press marks, die friction, or surface defects.

• 360° Uniform Circumferential Shrinkage: Balanced radial compression eliminates stress concentration, creating a dense, gas-tight joint cross-section with exceptional resistance to corrosion, vibration, and thermal fatigue.

• Superior Conductivity & Pull-Out Strength: Achieves a significantly larger actual contact area than traditional mechanical crimping, resulting in lower electrical contact resistance and maximum pull-out force for heavy-gauge Cu/Al connections.

• High Consistency & 3D Terminal Adaptability: Precise digital control and stable energy output guarantee 100% process consistency in mass production. Effortlessly adapts to complex 3D terminals, sheet-to-sheet welding, and irregular busbars

  Applications

  • EV High-Voltage Harnesses: Powertrain connections, motor leads, and charging interface cables (50–240 mm²).

  • Battery & Storage Systems (ESS): Battery pack interconnections, high-current Busbar-to-terminal joining.

  • Dissimilar Metal Joining: Heavy-duty Copper-to-Aluminum transition joints with zero thermal degradation.
