① Steam system: Accurate pressure reducer and PID control system(proportional
steam valve system) to keep very stable and accurate steam, ensure material
variation.
② Pressure control: Pressure sensor with multi-steam exhausting system to keep
expansion chamber pressure stable, as well as reduces the steam consumption.
③ Temperature control：The temperature sensor and compressed air proportional
valve maintains accurate expansion temperature, which in suitable for high
density expansion, resulting in less broken beads.
④ Material level control: Keeps accurate weighting scales and vibrated level sensor
control, ensuring less density tolerance.
⑤ Material filling system: Set filling weight in touch screen and electronic weighing
filling to realize filling accurately andautomatically.
⑥ Electric control: The PLC touch screen,electronic parts and valves are from
reputed brands, which make the whole working procedure automatic and stable.
