High-Filler PVC Compound Production Facilities for Cable Applications

PVC compound used in the cable industry requires different production conditions from standard plastic compound due to its high mineral filler ratio, controlled plasticizer content, and long-term thermal resistance requirements. VOLDE PVC Compound Production Systems offer integrated solutions covering the entire process for the precise dosing of powder and liquid raw materials, homogeneous mixing, and conversion into the final granular product. The system is designed for cable manufacturers targeting high capacity, repeatable recipe accuracy, and consistent quality

| Precise Raw Material Dosing for High-Filler Formulations

In PVC cable compounds, the ratio of calcite and similar mineral fillers can reach 40–70% in most applications. This makes dosing accuracy and mixture homogeneity critical. Bringing resin, filler, stabilizer, plasticizer, and performance additives into the process in the correct quantity and in the correct order directly determines the mechanical, electrical, and processability properties of the final granule. VOLDE systems ensure that both powder and liquid components are dosed in a controlled, traceable manner.

• Automatic weighing systems for PVC resin, mineral fillers, and additives
• Liquid plasticizer and stabilizer dosing units
• Gravimetric or volumetric feeding options
• Recipe-based control and data logging
• High-accuracy, repeatable production

| Integration of Mixing, Plasticization, and Pelletizing

PVC compound production is not limited to simply mixing materials; the steps of plasticization, homogeneous distribution, and conversion into granular form form the foundation of the process. Depending on the application, hot-cold mixer combinations or extruder-based compounding lines are used. VOLDE designs the system to ensure that all equipment, from raw material preparation to obtaining the final granule, operates in harmony with one another.

• High-speed mixer and cooling systems
• Twin-screw or single-screw extruder feeding infrastructure
• Controlled plasticization for melting and homogeneous distribution
• Water- or air-based pellet cooling systems
• Silo or big-bag filling solutions for the final product

| Process Continuity and Preservation of Product Quality

In PVC compound production, fluctuations in process parameters directly affect granule size, color stability, surface quality, and extrusion performance. For this reason, raw material flow, feeding continuity, and synchronization between equipment are of great importance. VOLDE systems keep material flow under control throughout the facility, helping production be maintained at the planned capacity and quality level.

• Controlled material flow from raw material to final product
• Suitable design in bin and transfer systems
• Dust control and central filtration solutions
• Monitoring of process parameters via automation
• Long-term, reliable production performance
