Key Features of EPS Pre Expanders:
Functionality: The machine heats polystyrene beads, causing them to
expand. This process can involve multiple stages to achieve the
desired density and expansion ratio.
Steam and Temperature Control: Precise control of steam pressure
and temperature is crucial for consistent expansion and quality of
the final product.
Production Efficiency: Modern EPS pre-expanders are designed for
high efficiency, allowing for continuous operation and rapid
production cycles.
Versatility: They can produce various densities of EPS, catering to
different industrial needs.
Environmental Considerations: Some models are designed to minimize
energy consumption and reduce emissions, aligning with
sustainability goals.
Applications:
Packaging field: It can be made into packaging boxes and packaging
pads of various shapes, which are used to pack various fragile and
valuable items, such as electronic products, glass products,
ceramic products, etc., and can effectively protect the items from
damage during transportation and storage.
Construction field: EPS particles can be heated and expanded, then
formed through molds and cut into insulation boards of required
sizes and shapes for use in thermal insulation of building walls,
roofs, and floors. They can also be made into decorative components
of various shapes, such as door and window frames, lines, flower
panels, etc., for decorating the interior and exterior of
buildings.
