Ultrasonic hand welder offers a low cost solution for parts where automation is not viable or production volumes are low. Application areas include spot-welding, staking of components, access to difficult weld areas and second operations/re-work.
The ultrasonic hand press offers a cost effective alternative to a standard pneumatic bench press. It is ideal for low volume production, offering an advantage over a hand held welder with its rigidly fixed welding head. The weld depth can be set giving consistent, repeatable results.
Ultrasonic welding is represented as a friction welding method, where oxides and other contaminants present on the material surfaces are broken up and also the components to be welded are brought together under simultaneous pressure. Molecular bonding, just like the conventional cold-press welding, then takes place. Ultrasonic welding is the conversion of high frequency electrical energy into high frequency mechanical energy. In ultrasonic welding spot welds in thin steels are produced by the local application of high frequency vibrating energy to work pieces held together under pressure. The work pieces are clamped together under a moderate static force applied normal to their face and oscillating shear stresses of ultrasonic frequencies (1 KHz to 40 KHz) with a power ranging of 700 to 6000 watts are applied parallel to the interface. The vibrating probe called "a sonotrode" induces lateral vibrations and slip between the surfaces fracturing the brittle oxide layers and softening the asperities because of localized heating. The combined effects of pressure and vibrations cause movement of metal molecule bringing about a sound weld.

Our hand-held thermoplastic welding tools meet two needs: welding of hard-to-reach areas and tamper-proof sealing of packaging.
In practically no time your production teams will be producing clean welds with our ultrasonic gun and pencil.
These tools are designed for ease of use, adaptability and flexibility to ensure clean and strong welds.
We have the solution to all your assembly needs.
We also have metal housing welding pencil, for welsing machine assembly.
Ultrasonic welding of plastics:
Plastics are typically engineered materials consisting of polymers. Polymers are shaped by polymerisation that may be a chemical action during which two or more molecules are combined to make a larger molecule. Polymers are often classified as either thermosets or thermoplastics. Thermosets aren't appropriate for ultrasonic assembly because they degrade when subjected to intense heat. Thermoplastics on the opposite hand soften when heated and cool when hardened and are thus ideally fitted for ultrasonic assembly.
Materials for Ultrasonic Welding of Plastics:
Most of the thermoplastic materials can be ultrasonic weldable. Teflon with low coefficient of friction and high melting temperature is impossible to weld using this process.
