Once EPS bead is pre-expanded it is transported through a series of tubes which are connected to hoppers on each press. During each molding cycle bead is drawn from the
hopper on the press and injected into the closed cast aluminum tool. The cycle commences as heat in the form of steam circulates throughout
the cavities inside the tool exciting the remaining pentane which causes
bead fusion. Once bonded together, the molded part needs to cool very
quickly to keep the part from melting. At this point, a vacuum is drawn
from the other side of the tool pulling the hot moisture out of the
part, allowing the part to cool instantly.
Finished
goods are then packed into boxes or stretch-wrapped bundles. If parts
need to be dried prior to packaging, they are stacked out to dry in
the mold room or in our hot room--which allows moisture to evaporate
more quickly.
