The 80FDE-4S(100) is a high-performance industrial extrusion blow molding machine engineered for precision and efficiency in plastic packaging production. Featuring a robust 4-die head setup and an advanced 75mm screw diameter, this machine delivers consistent plasticizing capacity (HDPE 85 Kg/h) and a maximum container capacity of 500ml. Designed for high-speed automated operations, it ensures exceptional wall-thickness uniformity, energy efficiency, and reliable continuous output for industrial manufacturing lines.
The 24:1 L/D screw ratio on the 80FDE-4S(100) represents a significant engineering advantage over conventional 20:1 designs. This extended compression profile provides 20% additional residence time for complete polymer melting and homogenization, translating directly to superior melt quality at the die head. The longer barrel enables gentler, more gradual compression that preserves polymer molecular weight while achieving the 85 Kg/h HDPE output rate.
Key Features
- Extended 24:1 L/D Screw Design: The 20% longer compression profile versus standard 20:1 screws delivers more complete polymer melting with reduced shear heating, preserving HDPE mechanical properties.
- Gradual Compression Profile: Progressive root diameter increase along the 24 L/D length applies gentler compression than short-ratio screws, minimizing polymer chain scission during plasticizing.
- Enhanced Mixing Homogeneity: Extended metering section length provides additional mixing time for complete homogenization of masterbatch colorants, UV stabilizers, and processing aids before die head delivery.
- Reduced Melt Temperature Variation: Longer residence time distribution narrows the temperature spread across the melt stream, reducing the ±3°C variation typical of short-ratio screws to ±1°C.
- Broad Material Processing Window: The 24:1 ratio accommodates a wider range of HDPE melt flow indices (MFI 0.2-2.0), providing flexibility to switch between different resin grades for various container applications.

Applications
Producers requiring consistent melt quality for thin-wall, lightweight containers where even minor melt heterogeneity causes visible defects or mechanical weakness. The extended L/D ratio benefits manufacturers processing recycled or blended HDPE materials with variable melt characteristics. Multi-product facilities switching between different container designs and resin grades benefit from the broad processing window.
