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.
