With the use of the Controller PLC (Programmable Logic Controller), touch screen, the machine performs the home-machine dialogue. And with negative pressure automatic charger (Automatic Negative Pressure Feeder), precision Balance electronic weighing and feeding (Precision Electronic Weighing Scale and Feeding Level Switch) level, the automatic power switch and precise measurement may be carried out. With the use of the automatic temperature control device and the press in the tank and the photoelectric automatic level control, density uniform and light foam beads can be carried out. Using a vibrating sieve, crushing lumps of raw materials of EPS and the fan blowing and conveying, one can achieve the first automatic cycle of expanded beads
