welding of plastic using ultrasonic
Ultrasonic welding of plastic materials creates a molecular bond within the weld seam. Longitudinal vibrations in frequencies of 20 kHz, 30 kHz, and 35 kHz with tool amplitudes between 5 μm and 50 μm are introduced into the plastic materials under the action of force. Ultrasonic vibrations are focused by means of special design of the components or tools. This specific geometry within a component is referred to as energy director. The contact points in the joining area are actively molded by means of energy input to achieve elastic deformation. Friction occurring between the contact surfaces and within the molecule chains generates heat that causes the material to melt.
Applicable all industry
Widely used in the automotive industry, electronic industry, medical industry, household appliances, woven apparel, office supplies, packaging industry, toy industry and so on.
automotive industry:
Highest weld quality: Vehicle parts must be joined to be tight, strong, dimensionally accurate and visually impeccable. Ultrsonic welding is a fast and economic solution for this complex task.
hygiene industry :Laminating of nonwoven materials using ultrasonics
The general principle of ultrasonic welding can also be applied to nonwoven materials. The thermoplastic fibers are activated by mechanical vibrations thus melting and bonding in pre-defined patterns. A weld tool, referred to as Sonotrode, transmits the vibration into the nonwoven material. In industrial applications, ultrasonic frequencies between 20 and 35 kHz are common, with amplitudes (tool travel distances) of 10 μm to 50 μm. Processing of nonwoven materials is often performed in continuous processes at high web speed. By application of rotary tools, it is possible to achieve processing speeds of up to 800 meters/minute. A specifically engraved drum is used as welding, embossing, or cutting anvil. The contour of the anvil drum focuses the energy and precisely defines the weld spots required for the respective product.
