Three elements to guarantee the quality of ultrasonic plastic welding products

In the use of ultrasonic plastic welder, in order to obtain a good welding effect, should pay attention to the coordination of various factors, among which the three important factors are: pressure, time, melting amount, these three are also known as the three elements to ensure the quality of welding, as long as the three aspects of good coordination, obtain high quality plastic welding products are relatively easy, the following is introduced to you.

1. Welding pressure

When the ultrasonic plastic welding machine is working, the appropriate pressure is selected to ensure the smooth transition of plastic parts from elastic to plastic excess, and the gap between molecules is eliminated, which is conducive to air discharge and has good sealing.

2. Welding time

Welding time directly determines the welding energy, because the power of ultrasonic plastic welder is generally fixed, the time is proportional to the size of the total energy, so if the master welding time is the key factor to determine the quality of welding, the time is short, the energy is not enough to support the welding parts, after a long time, lead to excess energy, not easy to form, so we should grasp the time according to the actual situation.

3. Melting capacity

The phenomenon of "virtual welding" often appears in the work of ultrasonic solders. The effective way to avoid virtual welding is to coordinate the hot melting time and thermal power, so as to obtain the appropriate melting amount and ensure that the molecular fusion of components is sufficient.

The above three factors are important factors that affect the quality of ultrasonic plastic welder products. Of course, there are many other factors that affect the quality of products. We will introduce them to you in the following article.
