Join thermoplastic components in 0.1–2 seconds using focused high-frequency vibration - no adhesive cure time, no solvent hazard, no mechanical fastener cost. 20 kHz and 40 kHz models. Digital energy control for consistent weld quality. Custom titanium sonotrode tooling. For automotive, medical, electronics, and packaging. IEC certified. Exported worldwide.
Ultrasonic plastic welding uses high-frequency mechanical vibration (20,000–40,000 Hz) focused through a precision-machined sonotrode onto the plastic joint interface. Friction generates localised heat within milliseconds, melting both surfaces. When vibration stops, the melt solidifies under pressure — forming a molecular bond in 0.1–2 seconds with strength equivalent to the parent material.
Samarth Electronics manufactures ultrasonic plastic welding machines for India's automotive, medical device, consumer electronics, and packaging industries — replacing adhesives (cure time, VOC emissions), solvents (health hazard), and fasteners (hardware cost, assembly time) with a fast, clean, and highly repeatable joining process. We supply 20 kHz (large/thick parts) and 40 kHz (thin/delicate parts) press-type machines, custom sonotrode tooling, and PLC-controlled automated production stations.
Extremely fast — no cure time, no cooling time. Parts are ready for inspection or packaging immediately after welding.
Titanium or aluminium sonotrodes FEA-designed and precision-machined to your exact joint geometry.
Consistent quality run-to-run regardless of part variation — energy (Joules) is the controlled variable.
Hand press to fully automatic rotary table or inline assembly cell with PLC and data logging.
20 kHz for large/thick parts and staking. 40 kHz for thin, delicate, fine-pitched plastic assemblies.
No adhesive, no solvent, no fasteners — electrical power and tooling are the only running costs.
