Ultrasonic cutting machines

Table of Contents

The systems of ultrasonic cutting Sonomax represents a technologically advanced solution for the simultaneous cutting and welding of synthetic or partially synthetic fabrics. The technology is based on the use of high frequency mechanical vibrations (20, 30, 35, 40 kHz) that generate localised heat to separate the material cleanly and precisely, without the need for traditional heating or blade maintenance.

This technology is distinguished by its high precision, the speed of the process and the ability to maintain the integrity of the materials, even with multiple layers. Unlike traditional blade or laser cutting methods, ultrasonic cutting does not alter the physical properties of the fabric, does not cause burns and minimises the production of dust and residues.

Sonomax machines are designed to offer maximum application flexibility, both in craftsman and highly automated production environments. Thanks to a modular and configurable range of handles, support structures and accessories, it is possible to meet the needs of different industries.

Advantages of ultrasonic cutting

  • Simultaneous cutting and weldinga single operation to separate and finish the edges.
  • Absence of frayingperfect for technical fabrics and layered materials.
  • Clean and even cuteven on curved or difficult shapes.
  • No burningheat is localised and controlled.
  • Very low energy consumptionlower than with hot technologies.
  • Zero blade maintenanceno fouling or residue to clean.
  • Reduced cycle timesNo preheating required.
  • Environmental compatibilityclean process, without fumes or chemicals.

Manual ultrasonic cutting systems

Sonomax manual systems are ideal for flexible machining, small batches and non-linear shapes. Thanks to the ergonomic handles and pre-tensioned structures, the operator can freely guide the cut without effort or risk of error.

Sonomax manual ultrasonic cutting frame

Manual cutting frame

Available frequencies: 30-40 kHz

Ideal for straight cuts. The structure is pre-tensioned, requires no adjustment and can be guided along a track with ease.

 Plastic sleeve handle

Plastic sleeve handle

Available frequencies: 30-40 kHz

Designed for curves and freehand cuts, even with a jig. Requires only light pressure to operate.

Reduced-angle aluminium handle for ultrasonic cutting

Reduced grip

Available frequencies: 30-40 kHz

Same features as the plastic sleeve handle, but optimised for narrow areas and small bending radii.

Systems for automatic ultrasonic cutting lines

Sonomax automated systems are designed for integration on frames, plotters and continuous production lines. They enable round-the-clock machining with constant reliability and precision, thanks to components optimised for wear, vibration and tension.

 

20 kHz ultrasonic cutting frame

20 kHz cutting frame

Available frequencies: 20 kHz

Suitable for edging or selvedge cutting. It can mount wheels with different cutting angles for more or less marked effects.

 

Selvedge cutting structure 40 kHz

Selvedge cutting structure 40 kHz

Available frequencies: 30-40 kHz

Equipped with cooling hood for continuous applications. Supports interchangeable casters and customised adjustments.

 

Pneumatic structure ultrasonic cutting on automatic lines

Pneumatic system with sleeve

Available frequencies: 30-40 kHz

Versatile solution for integration on plotters and automated systems. Customisable with dual pneumatic cylinders, clamping blocks and cooling caps.

Compatibility and customisation

  • Available frequencies: 20 / 30 / 35 / 40 kHz
  • Compatible generators: SX Series
  • Accessories: Sonotrodes, castors, cooling hoods, fixing systems and rails
  • Cables on mobile laying: shielded and flexible, to ensure reliability in dynamic lines

Industrial applications

Sonomax ultrasonic cutting machines are used in many sectors:

  • Technical textile: cutting polyester, nylon, PVC and multilayer fabrics without fraying.
  • Filtration: production of industrial filters with heat-sealed edges.
  • Medical: processing of masks, surgical drapes and PPE devices with sterilisable margins.
  • Automotive: finishing of interior cladding, panels, sound barriers and composite materials.
  • Packaging: shaping and finishing of plastic films and multilayer blisters.

How to choose the most suitable machine

Sonomax supports each customer with a customised analysis of application needs. They offer:

  • Pre-sales technical advice to identify the most suitable frequency, power and accessories.
  • Possibility of sample testing with detailed technical report.
  • Custom configurations for integration into existing production lines.
  • User training and after-sales service throughout Italy and Europe.
