Ultrasonic cut & seal

Welding and at the same time separating materials in one work step 

Ultrasonic cut & seal is used wherever it is necessary to seal edges during cutting or to make a process more efficient by combining the two work steps and bypassing subsequent punching devices. In the packaging industry , for example, the sonotrode table is used here, with which blisters, trays or cups can be sealed and punched out in a single step.

In the textile industry , cut & seal is used for welding elastic and non-elastic thermoplastic textiles, either continuously by means of a roll seam module or intermittently by means of stationary sonotrodes. The advantage of ultrasonic cut & seal is that the edges are already sealed during cutting, thus preventing subsequent fraying.

Advantages

• Combined welding and cutting or sealing and punching of:
  • Films and packaging, also if contaminated in the sealing area
  • Elastic and non-elastic synthetic textiles
• Fast and shortened process times with high process reliability
• Joining and cutting of several layers in one process
• No subsequent punching device necessary
• Reproducible welding and punching quality
• Complete monitoring of process parameters during production
• Flexible seam design
• Minimal seam protrusions
• Lint-free, firm, non-sharp punched edges
• Environmentally friendly technology
  • Low energy consumption and thus faster cycle times
  • No solvents or additives for welding
  • Pure recycling of the welded workpieces

 

Applications

• Blisters
• Trays
• Cups
• Fabric
• Artificial leather
