Screw Barrel For Cable Making Extruder

The Screw Barrel for a Cable Making Extruder is meticulously designed to plasticize, homogenize, and pressurize polymer materials—such as PVC, XLPE, or low-smoke zero-halogen compounds—onto electrical conductors; the screw features a specific L/D ratio (typically high for better mixing) and geometry (like barrier or mixing elements) to ensure consistent melt quality, while the abrasion- and corrosion-resistant barrel precisely controls the temperature profile and pressure, ensuring uniform insulation or sheathing thickness and optimal line speed for the cable manufacturing process.
