What if the ultrasonic welding machine can't weld? What if it is not strong?

With the continuous development of technology, for the efficiency process, all automatic production lines, or robotic welding technology has been adopted. The samples are normal when welding, but in the process of automatic welding, welding often does not occur, or welding In the case of a weak situation, what caused this? The small editors and technicians made a detailed examination of this situation and finally found various problems.

The reason that the ultrasonic welding machine can not be welded and is not strong:

First, the precision of the rack is not enough
Many manufacturers only buy generator equipment and install them on their own production lines. However, the rack design on many production lines is rough and the precision is low, which leads to poor welding results, no welding, or not strong. .

Solution: Replace the high precision rack.

Second, the problem caused by the ultrasonic welding machine itself,
Many manufacturers have a variety of plastic parts. The materials and sizes of plastic parts are different. When purchasing equipment, the plastic parts that are small in area and welded are tested. When replacing other types of plastic parts, Insufficient power of the ultrasonic equipment causes the welding to be unsatisfactory and not strong.

solution:
Replace the more powerful ultrasonic welder.

Third, the material of plastic parts has changed,
1. The raw materials on the raw material market are added with materials that affect the welding effect. For example, glass fibers that are not suitable for welding are added to the PC material.
2. The raw materials are recycled and reused by waste products, so the material is increased and the melting point of the material becomes high.
3. The material of the upper part or the lower part of the plastic part is changed, so that the melting point difference between the two workpieces is too large, which affects the welding effect.
The above three points are the metamaterial problems that affect the welding effect.

solution:
1. Replace a single hot melt raw material.
2. Adjust the welding time and pressure appropriately.
3. The upper and lower two plastic parts should be made of the same material or materials with similar melting points.
