Sonic Welding
Once the molded figure is ready to be assembled all the components are
gathered. These parts typically include the head, arms, legs and the torso
which is (usually) made in two halves - front and back. The parts are
assembled and once clamped in the torso will not come out. In order to seal
the torso so that it remains intact, it is sonic welded. Gluing could do
the job as well, but that would require a separate process and additional
expense. With sonic welding the assembled figure is subjected to
high-frequency sound waves which vibrate the seams of the plastic and cause
friction and high, focused heat. This heat actually melts or welds the
figure together. The process is very clean and allows for a strong, nearly
unbreakable bond to be formed.
