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.
Main features
1.The chamber surface is made by stainless steel with good shape and long life
2.The fluidized Bed Drier can be bought by customer solely.
3.The twice pre-explander can pre-expand once or twice to enable the EPSdensity to be ideal state.
Applications:
- Insulation Products: Producing expanded beads used in insulation panels.
- Packaging: Creating cushioning materials for fragile items.
- Construction: Making lightweight blocks and panels for building projects.
Benefits:
- Efficiency: Increases production efficiency by preparing beads for quick and effective moulding.
- Quality Control: Ensures uniformity in bead size and density, which is crucial for the final product quality.
