Handles for ultrasonic plastic welders

Manual grips 

Sonomax ultrasonic hand grips are the ideal solution for welding and cutting plastic materials in production contexts that require versatility, precision and safety. Used in both industrial and artisan environments, they allow rapid and localised interventions on complex components, small batches or repairs.

The handles are made of technopolymer materials that are highly resistant to impact, heat and mechanical wear. Each handle is designed to ensure electrical insulation, complying with safety regulations. The design is optimised for superior ergonomics: each model is balanced to reduce operator fatigue during prolonged use.

Main benefits

• No preheating required: ultrasonic energy acts instantaneously
• No emission of toxic fumes, unlike thermal welding
• Very low power consumption (below 600 W in the most compact models)
• Extremely low processing speed and cycle times
• High repeatability of results
• Compatibility with common plastics: PP, PE, ABS, PC, PA, PS, PMMA

All Sonomax grips support frequencies of 20, 30, 35 and 40 kHz and are compatible with SX series generators, interchangeable sonotrodes and boosters adapted to specific processing requirements. The operator can thus adapt the system to the characteristics of the workpiece and the type of joint required: spot welding, trimming, cutting.

Available types

• Pistol grip (Frequencies: 20-30-35-40 kHz): for spot welding in the automotive, appliance and electronics industries. Ergonomic design for right and left-handed use, trigger actuation, anti-vibration system.
• Plastic sleeve handle (Frequencies: 30-35-40 kHz): for cutting technical fabrics, TNT, felt, honeycomb or foamed materials. No use of blades, ideal for fashion, furniture, PPE, footwear.
• Reduced grip (Frequencies: 30-35-40 kHz): designed for tight spaces and complex geometries (electronics, medical, small components). Suitable for precision welding on small series.
• Handle + generator kitComplete solutions with generator, booster, interchangeable sonotrode. Available in different configurations (e.g. 20 kHz up to 1500 W or 40 kHz up to 600 W), with accessories such as bench stands, digital interfaces, cases, cooling systems.

Industrial applications

• Automotive: body repairs, headlights, bumpers, interior supports
• Medical: containers, PPE, plastic components
• Textile/TNT: cutting and welding of non-wovens
• Electronics: fastening of components, housings
• Home appliances: assembly of rigid plastics

Emerging and innovative contexts

• Bioplastics and sustainable packagingideal for PLA, PHA and biodegradable materials, without additives or glues.
• R&D and prototyping laboratoriesperfect for joining 3D printed parts, finishing edges and testing assemblies.
• Microprocessing and medical devicesprecise welds on uneven surfaces, without thermal or mechanical stress.

Technical support and customisation

Each handle is covered by warranty and technical support. Training courses for the safe and efficient use of ultrasonic grips are available on-site or online.

Thanks to the modularity of the Sonomax system, all handles can evolve together with your production: from the prototyping bench to the automated line.
