Ultrasonic Welding


Key hydraulics motion control challenges

Ultrasonic welding is an advanced process – and Bosch Rexroth has the hydraulics components and motion control expertise to handle demands such as:

  • Smooth, repeatable clamping forces
  • Maintaining the clamp force during high-frequency vibrational welding
  • Precise control of platen position—to better than 0.0001 inch
  • Better synchronization, synchronized, or coordination options available
  • On-the-fly adjustments
  • Bumpless transition to pressure/force control, to as low as 0.5 psi
  • Fast setpoint response, as fast as 2 ms
  • Compensation for platen weight
  • Simplified hydraulic circuits for a more compact design
  • Reduced machine cycle time
  • Increased repeatability
