  • ABSTRACT: Polymer-based compounds such as PVC, HFFR, PE, PP, and engineering polymers are widely used in the cable industry as sheath, insulation, and filling materials due to their mechanical, electrical, and environmental advantages. However, in their processing, challenges such as mixing homogeneity and production efficiency remain significant limitations in conventional systems. Inadequate mixing or uneven dispersion of additives not only reduces production efficiency but also directly affects the mechanical properties of the final product such as tensile strength, elongation value and flexibility. In this study, a multi-purpose compound production machine equipped with intermeshing and co-rotating counter-conical screws was designed, manufactured, and tested. The system consists of six main components: ribbon mixer, feeding unit, twin conical screws, transfer screw, granule cutting and cooling unit, and a PLC-based main control panel (HMI). The homogeneity and desired dispersion of the compound were confirmed by microscopic examinations, SEM analysis, and mapping analysis. Mechanical tests demonstrated that the compound had a tensile strength of 14.72 N/mm² and an elongation value of 173%, along with hardness, density, and moisture measurements, all meeting industrial standards. The developed machine provides significant advantages over conventional systems in terms of mixture homogeneity and production efficiency.
