Characteristics:

1.  This machine applies PLC and touch screen,automatic feeding,electronic weighing,temperature control,material level control to realize automatic production.
2. Electronic weighing system and material level control system assure the density of the foamed material, which make the bead uniform and keep the density tolerance within±2.5%.
3.  High precise guiding pressure reducing valve controls the temperature and steam pressure of the closed barrel, ensure the outcome pressure of the valve constant and the inner temperature controled within ±1%℃,which keeps the foamed material equal and prevents the bead agglomerate because of the bad temperature control.
4. Automatic material charging system improves efficiency and reduces labor intensity.
5. The closed constant pressure foaming barrel has high heating efficiency. It can save more than 50% energy compared to the continuous pre-expander.
6. Hot air drying system to dry the foamed material inside the barrel without fluidized drying bed.
7. Automatic discharging from the pre-extender,which can automatically filter, crush the ball material and transport the foamed material to aging silos.
8. Most of the main component are of world-famous brand,with reliable performance,stable quality,long service life and low maintenance cost.
9.  This machine applies automatic discharging system,the high pressure fan facility improves the speed of discharge.
10. The computer has memory function, which can record all information such as brands, specifications, expanding foam techniques and parameters of EPS material manufacturers. When customers want to use the materials that ever been used before just press the touch screen of computer to quickly go back to the original technique.
11. This machine is applicable in plateau oxygen depletion area,the production efficiency of continuous pre-expander machine is quite low under such circumstance.
