EPS foam blocks are large, rectangular or square-shaped blocks made
from expanded polystyrene beads, commonly used in construction,
insulation, and other applications.
Here are some key points about EPS block molding machines:
Bead Expansion: EPS block molding machines typically start with the
process of bead expansion.
Pre-Expanding Chamber: The pre-expanded beads are transferred to a
pre-expanding chamber within the machine.
Block Molding: Once the beads have been expanded, they are
transferred to the block molding section of the machine.
Closing and Pressing: When the expanded beads are in the mold, the
sections of the mold are closed, and pressure is applied to
compress the beads.
Cooling: After the pressing stage, the mold is cooled to solidify
the EPS foam and shape it into a block. Cooling is typically achieved through the circulation of chilled
water or other cooling methods.
Mold Opening and Block Ejection: Once the EPS foam block has cooled
and solidified, the mold is opened, and the finished block is
ejected from the machine.
