Good Sealing Performance Consistent with the Material Original Strength by 28Khz Ultrasonic Welder


Description:

Ultrasonic spot welder welding principle is to convert 50/60 Hz current into 20, 28, 35 kHz electric energy through ultrasonic generator. The converted high frequency electrical energy is again converted by the transducer into a mechanical motion of the same frequency, and then the mechanical motion is transmitted to the welding head through a set of amplitude modulator devices that can change the amplitude.
The horn transfers the received vibrational energy to the joint of the workpiece to be welded, in which the vibrational energy is converted into thermal energy by friction to melt the plastic.
The short pressure maintained on the workpiece after the vibration stops causes the two weldments to solidify in a molecularly linked manner. Generally, the welding time is less than 1 second, and the obtained welding strength is comparable to that of the body.
Ultrasound can be used not only to weld hard thermoplastics, but also to fabrics and films. The main components of a set of ultrasonic welding systems include ultrasonic generators, transducer/amplifier/welding head triples, molds and frames.


Principle of Ultrasonic welding:

When ultrasonic waves act on the thermoplastic plastic contact surface, high-frequency vibrations of tens of thousands of times per second are generated. This high-frequency vibration reaches a certain amplitude, and the ultrasonic energy is transmitted to the weld zone through the upper weldment. Let the pressure last for a few seconds to solidify it, thus forming a strong molecular chain for welding purposes, the welding strength can be close to the strength of the raw material. The quality of ultrasonic plastic welding depends on the amplitude of the transducer horn.

Advantages of ultrasonic welding process:

Ultrasonic welding machine principle, fast, economical, efficient, environmentally friendly welding process, especially in the operation of thermoplastic parts and other workpieces, especially highlighting the efficiency of the work, the current principle of ultrasonic welding machine is widely used in The synthesis of plastic products and plastic materials, the synthesis of metal parts and metal materials, as well as other materials and industrial and process operations.

It completely surpasses the old solvent welding operation, flux soldering, adhesive bonding and other flux-assisted fusion synthesis technology, which not only has the advantage of saving, because the advanced ultrasonic principle technology, no work pollution, and thus very environmentally friendly, The welding operation effect is comparable to the material itself, the welding quality is solid, the welding operation is beautiful, and the sealing effect of the welding operation is incomparable with the old-style process.

Ultrasonic plastic welding machine does not add any adhesive, filler or solvent when welding plastic products, nor consumes a large amount of heat source. It has the advantages of simple operation, fast welding speed, high welding strength and high production efficiency. Therefore, ultrasonic welding machines are increasingly used in a wide range of industries.

In the welding operation of the ultrasonic welding machine, the work material effect is deteriorated due to the different material properties of the product melted by the working phase, and the work effect of the same material is generally good.
