Strong Structural Ultrasonic Plastic Welding Machine Technology For Cast Thermoplastic
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.

Main features:
1. Compact product design, beautiful appearance, stable operation and easy installation
2. Can be used for the welding and riveting of thermoplastic products and the inlaying and blanking process between metal parts and plastic parts. The process of pasting organic melting agent has been completely replaced. It has the characteristics of low energy consumption, high efficiency, no deformation, no pollution, firm welding and convenient operation.
3. Not only can be used to weld metal, hard thermoplastics, but also fabrics and films. The hand-held ultrasonic welding gun can replace different ultrasonic welding heads according to the size of the riveting point of the product to be welded and the welding requirements, which is quick and convenient, and the cost is much lower than that of the special automobile door plate ultrasonic welding machine, which is convenient for satisfying different customers. demand.
