EPS pre expander uses high-strength square tube welded by tempering prevent form deformation, sandblasting rust, rust primer and paint greatly improve corrosion performance and service life of equipment. Electric controlled by Panosonic PLC and touch screen, from mold, feeding, heating, drying and releasing the fully automatic operation.

After the first phase of pre expansion of the EPS raw material, the second and third phases of pre expansions are optional. If annual production capacity is less than 2000 tons with density 12g/l, the only one unit of YF1200 is needed, which is capable of pre expanding heavy and light raw materials simultaneously; and as such can meet production requirement, improve production efficiency and reduce production space and energy. Here below the capacity for different type EPS pre expander for your information

With the use of PLC Controller (Programmable Logic Controller), Touch Screen, man-machine conversation will be realized.

Automatic Negative Pressure Feeder, Precision Electronic Weighing Scale and Feeding Level Switch make the automatic feeding and precise measuring come true.

With the use of Automatic Control Device for temperature and pressure inside the drum, and the Automatic vibration Level Control Device, uniformity of the density and light-weight of the foaming beads will be to realized.



  • Even density distribution

  • Homogeneous temperature distribution in the pre-expanding vessel

  • Stabilization of EPS-beads in the fluid bed

  • High material throughput

  • Low energy consumption

Process Control:

  • Density control

  • Temperature control

  • Pressure control
