Ultrasonic punching and sealing systems

Ultrasonic punching and sealing systems

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

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

MPW BT

The MPW BT variant is a manual work station at which the plastic components are manually loaded. The start is triggered with a two-hand start. 

• Robust machine structure
• Ergonomic workplace design
• Good accessibility for changing rolls
• Flexible setup

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). The MPW combines four automated single functions: punching of the membrane from the tape, fixing by vacuum and feeding, sealing with ultrasonics and further cycling of the tape. The product line can be flexibly integrated into automation lines or supplied as a manual work station.

Welding process control

Weld process controller MPW control

The weld process software of the MPW series provides answers to the rationalization and quality requirements of the plastics industry. Process-oriented user guidance via an 8.4’’ touch screen offers an especially user-friendly human-machine interface, which allows intuitive navigation. Task-oriented menu content provides excellent usability. 

• Process visualization 
• Quality monitoring by tolerance monitoring
• Vacuum monitoring
• Additional software for gapless data recording
