Ultrasonic Punch and Seal Machines

This ultrasonic punching and sealing system MPW (Modular Punch Welding) can punch and seal membranes in one production step. These unique systems provide solutions for manual work stations and automation integrations.

• 35 kHz operating frequency
• 1.5 s machine cycle time
• 4 product variants

This modular MPW weld system with an operating frequency of 35 kHz can punch and seal simultaneously in one production step. This makes the use of expensive pre-cut membranes unnecessary. This production unit is especially suitable for the processing of membranes, which are welded into plastic components as pressure balancing elements (PBE), or filters. The MPW combines four automated single functions: punching of the membrane from the tape, transferring the membrane to the weld position by vacuum, sealing with ultrasonics, and advancement of the tape. The product line can be flexibly integrated into automation lines or supplied as a manual work station.

This technology also offers a more ecologically friendly means of punching and sealing because it reduces cycle times and requires less energy than separate equipment.  Additionally, the combined functionality reduces the number of machines, and thus the amount of production floor space required.  For these reasons and more, these ultrasonic cutting and sealing machines offers significant advantages over other methods.
