Precise and Impeccable Ultrasonic Welding For Plastic Material


Description:


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.

FAQ: 

  1. What is ultrasonic welding?

Ultrasonic welding of thermoplastic materials is a weld technology utilizing mechanical vibrations to generate heat due to molecular friction. These vibrations excite the molecules in the plastic so that they start moving. The plastic becomes soft and starts melting. The components are bonded by cohesive or form-fit joints after a short hold time under pressure, they are firmly joined molecularly.


2. How does ultrasonic work?

Ultrasonic vibrations are mechanical longitudinal waves that

achieve deformation in plastic materials

cause friction between molecules

The resulting friction heat generates a melt that bonds the joining partners within the molecules.

Friction occurs due to impedances in the material, absorption and reflection of the mechanical vibration:

internal friction in the molecule bond = dissipative work

external friction between joining partners = surface friction


3. What does the complete ultrasonic welding system consist of?

The complete ultrasonic welding system is composed of active and passive components. The active components generate the vibrations, transfer them, and apply them into the weld parts The passive components absorb the resulting forces, maintain the parts in position, and particularly support the weld joint.
