Ultrasonic plastic welding machine first needs to get a good welding effect when using it. It is necessary to pay attention to the cooperation of various factors, and the most important three are: pressure and time, melting amount. At the same time, it is called the three key factors to ensure the quality of welding. As long as these three aspects are matched with each other, it is relatively easy to obtain high-quality plastic welding products, so let's give it to everyone. Do one by one.
1. The pressure on the welding
When the ultrasonic plastic welding machine is working, choosing the right pressure can ensure that the plastic parts smoothly move from elasticity to plasticity, and at the same time, the gap between the molecules can be removed, which is beneficial to eliminate the air and have a good one. Kind of sealing.
2, welding time
The welding time can directly determine the welding energy, because the power of the ultrasonic plastic welding machine is generally fixed, the time is proportional to the total energy, so if you can grasp the welding time is to determine the welding quality. The key factor, the time is short, the energy is not enough to maintain the welding of the components. If the time is long, it may lead to too much energy and it is not easy to form. Therefore, it is necessary to grasp the time according to the actual situation.
3, the amount of melting
Ultrasonic welding machines often have the phenomenon of “virtual welding” when working. However, the most effective way to avoid the false welding is to coordinate the hot melting time and the thermal power to get the proper amount of melting, and to ensure the molecular fusion of the components. Enough enough.
