Basic Information Of Ultrasonic Welding Machine？
High quality ultrasonic welding machine according to the level of automation can be divided into automatic welding machine, semi-automatic ultrasonic welding machine, manual welding machine, for modern enterprises, the higher the level of automation, the more conducive to the production of enterprise assembly line, so the use of automatic welding machine is a trend in the future of enterprises.
Fusion splicing method
Ultrasonic ultra-high frequency vibration welding head under moderate pressure, so that the two plastic joint surface friction heat and instant melting joint, welding strength can be comparable to the body, the use of appropriate workpiece and reasonable interface design, can achieve water tight and air tight, and avoid the use of auxiliary products caused by the inconvenience, to achieve efficient and clean welding.
Riveting welding method
The ultrasonic ultra-high frequency vibration welding head is pressed against the outstanding tip of the plastic product, so that it will instantly heat and melt into the shape of the rivet, and the materials of different materials will be riveted together mechanically.
preparetions
With THE high quality ULTRASONIC welding machine welding head and appropriate pressure, the metal parts (such as nuts, screws, etc.) are immediately squeezed into the reserved plastic hole, fixed at a certain depth, after completion of both tension and torsion are comparable to the strength of traditional mold molding, can avoid the damage of the injection mold and the shortcomings of slow injection.
The molding
This method is similar to the riveting welding method, the concave welding head is pressed on the outer ring of plastic products, the welding head gives out ultrasonic ultra-high frequency vibration and then the plastic is fused and formed and coated on the metal object to make it fixed, and the appearance is smooth and beautiful. This method is mainly used in the fixed forming of electronics, horn, and cosmetics lens fixation.
Spot welding
A. Welding two pieces of plastic points without pre-design of welding wire, to achieve the purpose of welding.
B, compared with large workpieces, it is not easy to design the welding wire of the workpiece for point welding, and achieve the fusion effect, can be simultaneously spot welding multiple points.
Cutting and sealing
Using the working principle of ultrasonic instant vibration, the chemical fiber fabric is cut, which has the advantages of smooth cut, no cracking, no drawing, and smooth appearance. High frequency wave and ultrasonic wave are two different concepts. High frequency wave refers to the electromagnetic wave with a frequency greater than 100Khz, and ultrasonic wave refers to the acoustic wave with a frequency greater than 20 kilohertz. High frequency welding principle, welding principle and ultrasonic is not the same, high frequency is the use of high frequency electromagnetic field to make the material internal molecules collide with each other to produce high temperature to achieve the purpose of welding and welding, and high quality ultrasonic welding machine is the use of friction heat principle to produce a lot of heat to achieve the purpose of welding and welding.
