1. It has PLC programmable controller and touch screen control, automatic baiting, automatic electronic measuring, automatic control of the barrel's temperature, pressure and seasoning. It can expand materials in one pass to assure the automatic cycle production.
2. It has electronic weighing system and photoelectricity material level control system to assure the right volume of the foaming material, make the beading density uniformly after foaming and the error is less than 3%.
3. Japanese made high precision guide pressure reducing valve control the temperature and steam pressure of the barrel, assure the outcome pressure of the valve constant and the inner temperature control within 1. It can keep the foamed EPS raw material consistency and prevent the EPS raw material agglomerate because of the bad temperature control.
4. It has automatic negative pressure charging device and electronic weighing system, which combined with level switch to charging automatically, rising efficiency and reducing labor intensity
5. The shell has enclosed type constant pressure foaming barrel with high thermal efficiency to save steam. It can save more than 50% energy compared to the continue type pre-expander.
6. It has high quality enclosed type of hot air seasoning system to season the foamed raw material without sulfuration drying bed.
7. After discharging from the pre-extender, it can autofilter, crushing the ball material and transport the foamed raw material automatically to slaking bin.
8. The electric appliances, pneumatic components, and valves of the machine are all well-known brand, to ensure the operational stability and reliability and service life of machine.
9. The automatic discharging of shell applies high pressure fan facility to dry materials, which promotes the speed of output.
10. The computer has the memory function, which could record all information such as brands, specifications, expanding foam techniques and parameters of EPS material manufacturers. When used materials of one manufacturer is needed, just press the touch screen of computer to quickly go back to the original technique.
11. It has compact conformation with less floor area because of the combined electronic weight and seasoning in the barrel.
12. The machine is available to the foaming production in plateau oxygen depletion area, and appears the advantages of pressure extender (the production efficiency of continuous pre-expander is quite low in the same condition).
