Can polypropylene be sonic welded
WebMar 7, 2009 · This pooling of plastic material helps contain the material and increases the likelihood of a hermetic seal. The additional height of .010 to .025” added as a gap around the periphery of the part provides a shadow line that helps to hide variation with part tolerances and melt flow during the ultrasonic welding process. WebIf you must use PP (it is generally more corrosion resistant than ABS), you might want to consider a glue with a solvent applied to plastic first to open it up, or spin welding. On …
