Insertion of inserts or components into plastics by means of ultrasounds.
Ultrasonic insertion heats up thermoplastics by means of low-frequency mechanical vibrations emitted by a sonotrode. The sonotrode operates between the article and the insert. Thanks to the heat generated by the mechanical vibration, the material reaches the necessary plasticity degree to envelope the external profiles of the insert. In the following cooling phase, the joining of element and article hardens until it gets fixed solid.
This inserting technique produces a sort of welding between article and insert and is used to insert inserts made of plastics and metal.
The ultrasonic insertion can be applied to article produced by means of injection moulding, extrusion moulding, compression moulding, thermoforming, blow moulding, suction 2D/3D (2k) and rotational moulding.
Among the components into which the machines of GS Finishing Machines have inserted components by means of ultrasounds there are the following, listed as an example: battery boxes, automotive pedalboards, supports for the steering column, filter boxes, tanks, pipes, conveyor ducts, light cases and accessory components of any nature.
