Advantages of ultrasonic welding:
1. High production efficiency, single piece of plastic processing only takes 3 seconds, and there is no need to maintain pressure and dry
2. The professional level of the operator is not high, no training is required, just press the button, pick and place the parts
3. The welding seal is good, seamless welding can be achieved, and water and air tightness are guaranteed
4. High welding strength, basic tensile test 200N is no problem
5. When welding samples, there is no flying dust or smoke, sparks, colorless and odorless, and will not cause pollution to the working environment
6. Different products only need to customize molds, and a set of equipment can be used, so the utilization rate of the equipment is very high
7. The machine is operated by two buttons and two hands, and the safety performance is guaranteed. In special cases, an external foot switch can be connected
8. The machine is controlled by a cylinder, all welding parameters are set, and the welded products are highly consistent and the scrap rate is low
9. The only vulnerable part of the machine is the ultrasonic mold, which has a service life of 3 months and is used about 200,000 times
10. The machine is very simple to install. As long as it is powered on and ventilated, it can be processed and produced
11. It is easy to realize automation. The equipment has input and output signals, and it can be automated by connecting it to the automation equipment
12. The cleanliness requirements for the surface treatment of plastic workpieces are not high
13. It can be used for welding of workpieces of various plastic combinations and mixed materials. It is best to send samples for testing in advance
14. It is close to cold processing and will not generate sparks
15. Low power consumption cost, single-piece power consumption cost = 6 yuan (6 degrees * 1 yuan/degree) / 5000 pieces (8 hours of output)
Disadvantages of ultrasonic welding:
1. There is a size limit on the welding area size of the welding workpiece. The maximum welding size area of the standard ultrasonic machine is 30*30cm, and it must not exceed this range. If you want to continue to use the ultrasonic process for larger samples, you have to consider making a non-standard ultrasonic machine, such as making it into a multi-head parallel type, or using other processes such as hot plates.
2. Ultrasonic welding will inevitably produce harsh noise. The larger the workpiece, the greater the noise. It is best for employees to wear earplugs when working with ultrasonic machines. If you want to avoid ultrasonic noise problems from the source, you can add a glass soundproof cover to the machine.
3. Ultrasonic metal welding has many restrictions and can only weld thin metal sheets and thin metal wires.
4. It is difficult to design a welding head for workpieces with special shapes and complex structures.
