When using Ultrasonic Plastic Spot Welding Machine, in order to obtain a good welding effect, attention should be paid to the combination of pressure, time, melting amount of three factors, as long as these three aspects are well coordinated, it is easy to weld high-quality plastic welding products.
1. Welding pressure
When the ultrasonic Plastic Spot Welding Machine works, select the appropriate pressure to ensure the smooth transition of plastic parts from elasticity to plastic excess, while eliminating the gap between molecules, which is conducive to air discharge, with good air tightness and water tightness.
2. Welding time
Welding time determines the welding energy, because the power of the ultrasonic spot welding machine is generally fixed, and the time is proportional to the size of the total energy, so if the welding time is the key factor that determines the quality of welding, the time is short, the energy is not enough to support the welded parts, after a long time, resulting in excess energy, it is not easy to form, so it is necessary to grasp the time according to the actual situation.
3. Melting amount
In the work of ultrasonic handheld spot welding machine, the phenomenon of "virtual welding" often occurs, and the effective way to avoid virtual welding is to coordinate the hot melting time and thermal power to obtain the appropriate amount of melting and ensure that the molecular fusion of the components is sufficient.
