40 kHz Ultrasonic Welders
high frequency, gentle action.
The preferred frequency for delicate, small, close‐tolerance assemblies. These fast, precise and virtually inaudible models are ideally suited for plastics assembly with products such as printed circuit boards, microelectronic components and medical devices.

A complete 40 kHz system is comprised of a welder and a power supply best suited to your application(s). 

Model 4095

The 4095 Welding Press is a bench-top unit with a rigid cast aluminum base, dual, non tie down, antirepeat palm buttons, and emergency stop. The press has adjustable pressure triggering and an adjustable positive stop. For greater operational flexibility, the power supply can be remotely positioned up to 35 ft. (10.6 m) from the welder.     

  • Bench press with removable cast aluminum base
  • Optional linear encoder for distance welding
  • Direct in-line air cylinder
  • Pneumatic speed controls

Model 4096

Designed for use in automated assembly systems, the Slimline head can be mounted in any position on a bridge or other structural member. The welding head is guided on precision linear roller bearing slides and can be matched with all of Sonics’ power supplies including models GXT, GXE and GXL.

​
  • Slimline actuator designed for automated systems
  • Optional linear encoder for distance welding
  • Can be mounted in virtually any position on a bridge or other rigid structure
