Why the ultrasonic plastic welding machine has good welding effect
Ultrasonic plastic welding machine is usually called ultrasonic plastic welding machine. We often say that ultrasonic plastic welding machine is simpler in operation than general welding, welding speed is faster, and welding strength is higher. Then, why is there an opportunity for ultrasonic plastic welding? So many benefits? I believe everyone understands the relevant knowledge of ultrasonic plastic welding machine at a glance:
1. How is the plastic bonded?
After using the above method to ultrasonically high temperature, due to the poor thermal conductivity of the plastic, the heat cannot be dissipated in time for a while, and it will be concentrated in the welding area, which will cause the two plastic contact surfaces to melt rapidly. The melted plastic will be subjected to external force. Make the two plastics adhere well together. After the tape is firmly bonded, remove the external force, so that the two plastics are well integrated, and the welding strength is better.
2. Several factors that affect the welding effect
The welding effect of the ultrasonic plastic welding machine is good or bad, and the main influencing factors are as follows: (1) The amplitude of the transducer welding head. The transducer can control the ultrasonic wave, control the vibration amplitude, so as to control the temperature it produces; (2) Welding time. The welding time guarantees the bonding effect of the two plastics, and how stable is the bonding after bonding; (3) The size of the external force. The external force is to ensure a better plastic bonding effect, and the external force should not be too large, otherwise it will easily cause deformation.
3. Composition of ultrasonic plastic welding machine
The ultrasonic plastic welding machine is composed of a pneumatic transmission system, a control system, an ultrasonic generator, a transducer, a tool head, and a mechanical device. The system can realize intelligent control, so the welding effect is clear at a glance through digital imaging technology, and the welding effect is fully guaranteed.
4. Safety of ultrasonic plastic welding machine
In addition to the better welding effect than general welding, the ultrasonic plastic welding machine has a safe welding process and does not produce pollution, which is another important feature. The high temperature of traditional welding is not easy to control, and it is extremely dangerous when people are welding. , The light generated by welding is also easy to stab human eyes, and the welding effect is related to the proficiency of the technicians. Therefore, it is difficult to control.
5. How does high temperature occur?
When plastic welding, we need high temperature, ordinary welding, high temperature is generated by gas combustion, such as: acetylene, etc., for ultrasonic plastic welding machine, the high-temperature ultrasonic is to generate high-frequency vibration through ultrasonic waves, this high-frequency vibration, Ultrasonic energy can be transferred to the weld zone through the weldment. Because the weld zone, that is, the interface between the two welds, has a large acoustic resistance, high temperature is generated.
Ultrasonic plastic welding technology has brought the welding industry to a new level. Welding is used more widely, so that different plastics can be well integrated, and plastic products can be used more widely in our lives. The continuous progress of ultrasonic plastic welding machines will bring more and more convenience to our lives.
