Ultrasonic Welding Machine for grading cards is 20K Ultrasonic Welding Machine

Grading card is hot these days.Refer to the basic rules to a good slab:first the slab is requested to be sealed strong, then, a clear slab should be with no whitening since it  should be very clear.But how to seal a good slab The answer is to use an Digital Ultrasonic welder.

The slab is made of plastic material. Generally speaking, if one would like to join two plastic parts, there may be about three common ways for him to choose. To use glue, or to use hot melt, or ultrasonic technology.

Mentioned to the slab, ultrasonic welding technology is undoubtedly the most suitable. When using glue or plastic hot melt  , it may cause environmental pollution;also,because of that using 100% manual operation, the working efficiency will be very low; And there may be something fluid plastic overflow which cause the appearance bad. Therefore, by using ultrasonic welding to seal a slab, it is high efficiency and environmentally friendly. Also because that compare to the other two plastic joint method, the 20K Plastic Ultrasonic Welding Machine can provide the strongest seal and the best appearance of a slab.

When to seal a slab,it is important to choose a correct machine with correct frequency and power specially for the slab; also, the slab 's quality and material will also affect the welding results.
