The ultrasonic welding of the oil-jet plastic shell uses a special ultrasonic protective film, also called a synthetic fluorine protective film. It is a frosted and translucent protective film material. It is non-sticky, no glue, soft and elastic, and has a delicate hand feeling. Above 150 degrees. Ultrasonic special protective film has excellent practical performance and high reusability. The number of uses is 5-8 times that of ordinary film. According to the pressure, frequency, and time of ultrasonic adjustment, the number of uses will be different. Effectively improve and solve the plastic products such as fuel injection plastic shell, ABS plastic shell, ABS+PC plastic shell, PC plastic shell, nylon plastic shell and other electronic appliances, toys, auto parts, bicycle parts, motorcycle parts, handicrafts, daily necessities, etc. The use of pressure welding protection and appearance problems in ultrasonic pressure welding.
Its advantages are to increase productivity by multiple times, reduce costs, improve product quality and safe production. The ultrasonic energy is transmitted to the welding area through the upper weldment. Because of the large acoustic resistance at the welding area, that is, the interface between the two weldings, local high temperature will be generated.
