The following content is about the application guide of Dongguan Ultrasonic Plastic Welding Machine:
1, welding:
The working principle of ultrasonic welding requires two combined parts, one vibration on the top, and one static on the lower side, and the frictional heat on the contact surface melts and bonds the plastic on the surface. Therefore, reducing the initial frictional contact surface and making the ultrasonic energy concentration is very important for improving the welding efficiency and quality. Therefore, one part of the welding (usually the upper part) is required to have a convex ridge on the welded joint. , referred to as "energy guiding edge";
2, implanted:
Ultrasonic metal embedding is the use of sonic vibration and pneumatic pressure to embed the metal of the outer surface of the flower in the pre-cast plastic hole. (Figure 2) The principle is that the ultrasonic wave transmits the vibration energy through the special hardened vibrating head. To the metal object, the metal material transmits the vibration energy to the plastic, and the two materials are sharply rubbed to melt the contact surface plastic, and the moderate pressure is applied to implant the metal into the depth;
3, riveting:
To fix a metal or accessory to a plastic part, or to join two plastics that are not compatible with each other, a riveting method may be used. When the diameter of the rivet core is larger than 4 mm, the C form is recommended;
4. Forming:
The principle of ultrasonic shaping is roughly the same as that of ultrasonic riveting;
5, spot welding:
When hot-melt plastics need to be welded, due to various conditions, if the melting point cannot be added, and when the riveting is not possible, spot welding can be used to form the welding. The principle of spot welding is to pass the tip of the welding die through the upper panel to reach the lower panel. It is half the thickness of the upper panel. The upper panel is melted and plasticized by the small end of the welding die, and the material thickness of the spot welding is preferably 0.8-5.5 mm.
