Description

technical field [0001] The invention relates to a testing device, in particular to a testing device which utilizes ultrasonic frequency vibration to realize melting and plasticizing of polymers. Background technique [0002] Injection molding technology is famous for its low cost, ability to mold complex structural parts, easy mass production and good performance of polymer materials. The flow properties of polymer melts significantly affect the molding process of injection molded products. Due to the high viscosity of the polymer melt itself, it requires high injection pressure and injection speed when molding thin-walled products in conventional injection molding, otherwise short shots will occur. The micro-injection molding technology that has been booming in recent years has a very small injection volume (generally a few milligrams), shallow runners and small cavities during the molding process, rapid cooling of micro-melts during the filling process, large flow resista...
