Specifications of Foam Pre-expander EPS Granules Machine With Polystyrene

1.Fully automatic multifunctional machine, applies PLC and touch screen, automatic feeding, electronic weighing, temperature control, material level control to realize automatic and continuous production.
2. Electronic weighing system and material level control system ensure the density of the foamed beads, which make the beads uniform and keep the density tolerance within 2.8%.
3. Japan original pressure reducing valve controls the steam pressure of the chamber, which ensures the outcome pressure of the valve constant and the inner temperature stable, which keeps the foamed material equal and prevents the beads agglomerate because of the bad temperature control.
4. The electronic weighing device, automatic feeding device, PLC central control, automatic weighing, feed, improve production efficiency, reduce labor intensity.
5. Using barrel closed pressure foaming, high thermal efficiency, saving steam, short curing time, high foaming ratio, beads than uniform, continuous pre-expansion machine energy savings of more than 50% .
6. The machine has a large capacity of the automatic control system of fluidized bed drying, with continuous drying and beads by crushing feeding devoice is sent to the cooking bin function etc...
7. Electric and pneumatic components are well-known brands, with reliable performance, stable quality, long service life and low maintenance cost.
8. 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.
9. The machine adopts weighing system below, reducing the machine height, some parts are set to the upper part of the frame, with compact structure.
10. the machine adopts pressure supply system, foam production therefore suitable for high altitude hypoxia area, the advantage of pressure foaming machine.
