The key of ultrasonic plastic welding is the design of solder joint and ultrasonic horn design. In ORDER to achieve the best effect of ultrasonic plastic welding, it is necessary to choose the appropriate ultrasonic power, pressure and welding time, and to fix the parts of the fixture, welding joint surface of the interface shape reasonable design.
Design of welding points:
To design a reasonable solder joint structure, the solder joint structure in the connection strength must reach the predetermined index, at the same time the appearance should be as beautiful as possible.
The structure of the solder joint is related to the thickness of the weldment. With the thickness of the weldment, the size of the weldment is different.
Welding surface design;
In order to make the ultrasonic energy concentrated in the plastic welding process, shorten the welding time, improve the welding quality, the same welding surface structure needs to be customized design.
When two plastic parts need to be welded in plane, the welding wiring should be designed. The welding quality of two smooth planes can not be guaranteed effectively.
If a convex edge with a certain cross-sectional area is designed on the welding surface of a weldment, which is called the energy seeker, the ultrasonic vibration energy can be concentrated in the welding process and the welding time can be shortened.
After MELTING, THE CONVEX edges (ENERGY GUIDES) ARE JUST evenly spread over the welding surface, so as to produce a firm connection strength and reduce the deformation of the welding surface.
Use a triangular energy seeker instead of a rectangular energy seeker, the effect will be better.
Welding surface design benefits;
In process practice, there is no energy guide (guide wire), the welding effect is very different. Under the same conditions, the energy seeker can shorten the welding time by a lot.
Different uses of plastic products on plastic welding surface structure requirements are also different. Some emphasize beautiful appearance, some emphasize welding strength, some emphasize good sealing and so on.
The structure of the weldment itself has great constraints on the shape of the weld surface. Therefore, the design of welding surface must be considered comprehensively according to the specific requirements and weldment shape to form a variety of differentiated welding surface.
