eps pre-expander machine

1) This automatic batch pre-expander has a PLC and touch panel with a full automatic production cycle controlling filling electronic weighing, chamber temperature,pressure and level testing 2) It uses an electronic weighing system and level sensor to control raw material volumes and expanded density, while ensuring density tolerances within 3% 3) With the adoptions of the German comparison valve (installed additionally according to the customer's demand and Japanese high accuracies of the decompression valve control the temperature and the steam pressure in the chamber, which can guarantee the stability of the pressure in the decompression valve export, thus the chamber temperature is controlled to within ±1%, also guarantee the consistency of the emanative raw material of EPS, and prevent if from agglomeration because of bad control of the temperature
