Ultrasonic Cutting Gets A 50-Year Makeover

Fifty years after launching its first ultrasonic cutting and welding devices, French manufacturer Decoup+ by Spoolex is giving the technology a new look while keeping the engineering underneath largely unchanged.

Now comes the Advanced Design Series, a redesign of its manual range focused on ergonomics and easier handling rather than a fundamental change in the technology.

The new range includes the P 300W ultrasonic gun, T 300W tabletop cutting unit and Mini Press 300W.

And that is the interesting part. Ultrasonic technology is still finding plenty of work in textiles, particularly where clean, precise cutting or welding matters.

The process converts an electrical signal into mechanical vibrations. These vibrations generate localised heat, allowing thermofusible materials to be cut or welded. For textile manufacturers, that includes synthetic and technical textiles, nonwovens and thermoplastics.

The attraction is simple: the material can be cut or joined quickly and precisely, without burning, discoloration or creating excess thickness. Once the vibrations stop, the material solidifies almost immediately. In suitable applications, the finished component can go straight into use without additional processing.

Decoup+ developed its ultrasonic technology in the early 1970s with French engineering school ENISE and launched its first range in 1975. Since then, the technology has evolved into both manual equipment and systems that can be integrated into production lines.

Fifty years on, the message is straightforward: sometimes established technology does not need replacing, it needs to become easier to use.
