iQ Servo Advantage

iQ Dynamic Servo Motion Control - NO Pneumatics!
Integrated all-electric true servo technology eliminates the variability associated with pneumatic press components resulting in improved process repeatability and accuracy. Dynamic Servo Motion Control technology delivers precise control of ultrasonic stack velocity, force and location providing a more optimized and robust process.

• Repeatable and accurate Servo Motion Control
• Integrated Melt-Match® Technology
• Dynamic Velocity Melt Initiation (DVMI™)
• Precise velocity/force control during initial application of sonic energy allowing for optimization of joint melt initiation. (Patent Pending)
• Programmable stack velocity and location control
  • Reduction in cycle time.
• Ideal for integration into automated assembly systems where high precision and reduced variability is desired.

iQ Calibration and Validation
100% digital all-electric control simplifies the calibration and validation process. By removing the pneumatic components, validating your ultrasonic welding process has never been easier and is ultimately more reliable. The advanced all electric press and digital control features of the iQ Series welder will assure that your calibration/validation will stay in tolerance for a longer time. This provides more confidence in the welding output between calibration schedules while maintaining system repeatability.

• Simple calibration procedure - no pneumatic components to adjust
• Only one device required for calibration (Trigger Force Sensor)
• All other parameters validated (no adjustment - functional tests only - distance, time & velocity)
• Optional Dukane calibration/certification prior to shipping.
• Dukane calibration technicians available for on-site calibrations as required

iQ GREEN
No pneumatics = NO compressed Air!

One of the highest cost manufacturing today is associated with energy required to generate compressed air for pneumatic operations. It is estimated that only 50% of the compressed air generated is used for operation; the rest is lost due to leaks and waste.

  • Integration with barcode scanner and/or laser marker system for FDA documentation.
• No operator accessible adjustment knobs or controls.
  • Ensures validated process remains unchanged.
• All mechanical changes require a specific tool.
• Clean room friendly
  • No air exhaust to filter
  • Stainless steel panels

iQ Process Control

To optimize the welding process and produce the strongest and most consistent weld results, it is critical to look at all phases of the welding process for each application.

Pre-weld Control

• Programmable home position
