Infinity™ with Melt-Match®

Patented Melt-Match® Technology

Produce fast and consistently by programming ultrasonic stack velocity, force, and position throughout the entire welding process for stronger welds.

Accurate & Reliable Ultrasonic Welding

Weld more accurately and reliably thanks to a tighter standard deviation of dimensional accuracy and 100% digital all-electric control.

Lower Production Costs

Since ultrasonic welding doesn’t require filler materials, adhesives, or fasteners, you can reduce production costs for each project.

Replicate Proven Welding Processes

Easily replicate a proven welding process from one Infinity system to another with the 100% digital all-electric control. No adjustments to pneumatics are needed.

Weld Various Types of Materials

A wide variety of thermoplastics and metals can be welded using this Ultrasonic Welder for more flexibility in your production.

Take Control

Take full control of each phase in the ultrasonic welding process with the Infinity™ Ultrasonic Welding System with Melt-Match®. It delivers accuracy, reliability, and easy replication of proven processes for faster and more cost-effective production. By using Melt-Detect™ a user can avoid deformation of energy directors during the welding process, get uniform melt, and a hermetic seal. Melt-Match® parameters control the welding process “in motion” with real-time closed-loop force control in addition to the real-time velocity control. Force and weld velocity can be programmed in 10 independent segments to match the melt flow rate of the material.

Don’t leave any room for error in your ultrasonic welding process. With the Infinity™ Ultrasonic Welding System, you have control and flexibility in how to program and implement your welding process for maximum efficiency and effectiveness. Buy the Infinity™ Ultrasonic Welding System with Melt-Match® to have full control over your ultrasonic welding process! 100% Money-back guarantee.
