A. Pressure control, The Continuous Pre expander adopts pressure reducing valve (Yoshitake, Japan) with PID valve (Burkert, Germany) to control the steam pressure, ensure constant pressure, constant temperature to achieve the foaming precision.
B. Material level control, it adopts Germany imported vibration level sensor to control the foaming level precision to achieve the beads density precision.
C. Material feeding weighing control, it adopts electrical weighing feeding system, setting the feeding weight through touch screen, and automatic weighing to achieve material feeding weight precision.
