Ultrasonic waves generate high-frequency signals through an oscillating circuit, which are then converted into mechanical energy by a transducer (that is, high-frequency mechanical vibration energy beyond the human ear's auditory threshold). This energy is transmitted to the plastic workpiece through the welding head. The vibration of hundreds of thousands of times per second, combined with pressure, causes the joint surface of the plastic workpiece to melt after intense friction. After the vibration stops, the brief pressure maintained on the workpiece allows the two welded parts to solidify into one body in a molecular bonding manner. Generally, the welding time is less than1 second, and the obtained welding strength can be comparable to that of the original body. Ultrasonic plastic welding machines can be used for butt welding of thermoplastic plastics, as well as for processing technologies such as riveting, spot welding, embedding, and cutting. The size and shape of the mold are designed according to the appearance of the product.
The principle of ultrasonic plastic welding is that the generator produces high-voltage and high-frequency signals of20KHz (or15KHz). Through the transducer system, the signals are converted into high-frequency mechanical vibrations and applied to the plastic workpiece. The temperature at the interface rises through the friction between the workpiece surface and the molecules. When the temperature reaches the melting point of the workpiece itself, the workpiece interface melts rapidly and then fills the gaps between the interfaces. When the vibration stops, the workpiece cools and takes shape under a certain pressure, achieving a perfect weld. Welding scope: toy industry, stationery industry, household appliance industry, electronics industry, food industry, communication industry, transportation industry, aerospace, etc.
Ultrasonic welding examples:
Daily necessities industry: powder boxes, makeup mirrors, hair combs, lock rings, vacuum flasks, sealed containers, seasoning bottles, water pipe joints, handles, bottle caps, food containers, car lamp covers, car water tanks… etc. Toy industry: various ball toys, stationery, water guns, plastic gifts, music toys, and various plastic toys… etc.
Electrical appliance industry: electronic clocks, steam irons, vacuum cleaners, telephones, computer keyboards, electric fans, batteries… etc.
Automobile manufacturing industry: car lights, rearview mirrors, interior trims, bumpers, various plastic products… etc. Electronics industry: mainly produces power supplies, adapters, chargers, mobile phone casings and many other plastic-related products. The electronics industry is currently the industry that uses the most ultrasonic plastic welding machines.
Main structure of the equipment and component brands
1、Transducer system:It uses Japanese original crystal transducers and Japanese top - brand steel amplitude rods. It has strong power, is sturdy and wear - resistant, and has 20% higher power than similar domestic transducer systems.
2、Pneumatic components:It uses well - known brand large - diameter cylinders Φ63*80MM—20, five - way solenoid valves. It runs smoothly up and down, has a good buffering effect, eliminates the impact force of the welding head on the workpiece and the recoil force on the transducer, which is more conducive to welding relatively precise workpieces and effectively protects the piezoelectric ceramic chips. This machine is equipped with a precise fine - tuning mechanism, and the fine - tuning distance can be precise to 0.02mm, and there is an instrument indication. Both the height of the machine body and the descending distance of the welding head are indicated by scales, with an accuracy of 1.0mm;
3、Rack:The unique rectangular column design provides higher mechanical strength, effectively avoiding the backward tilting phenomenon during operation. All the rack sheet metals are processed by laser cutting machines and CNC plate shearing and bending machines, ensuring excellent assembly fit of the whole machine. The whole machine is fully painted, with good adhesion, no peeling, and an elegant and beautiful appearance.
4、Motion structure:The equipment uses well - known Taiwanese linear slide rails with extremely high precision (uncomparable to the traditional guide rods with linear bearings), and they are sturdy and wear - resistant, making the welding head descend more smoothly and precisely, which is more conducive to welding relatively precise products.
5、Balance mechanism:The transducer assembly can be rotated freely. The transducer assembly is equipped with a horizontally adjustable structure, and the workbench is also equipped with an adjustable structure. These two adjustment structures make it more convenient and faster to adjust the mold, easy to operate, and easy to learn.
6、Electrical system:It is assembled with a full set of high - quality imported components. The power amplifier part has an improved design, adding an amplification component to share the load, reducing the temperature rise of the triode and the damage rate. Without a programmable control board design, the mechanical time dial switch is replaced by a Japanese OMRON time relay, making the time control more accurate and reliable.
Characteristics of the whole machine:
■Japanese original piezoelectric ceramic transducer with strong and stable output
■Titanium alloy horn, sturdy and durable
■Square columns, guide bearings, and precision fine-tuning devices
■Adjustable base plate structure, convenient and fast for mold debugging
■Split structure to avoid interference
■All high-quality imported parts and components, quality guaranteed
