Overview
Extruder central feeding systems are critical components in PVC processing. They ensure raw materials and additives are fed accurately, continuously and efficiently into extruders, supporting consistent product quality and stable production flows.

Key Benefits

• Increased productivity through automatic, uninterrupted feeding and continuous production flow.
• Improved product quality via precise dosing and homogeneous material supply.
• Reduced operational costs by minimizing waste and optimizing raw material management.
• Enhanced safety and hygiene with closed systems that prevent dust and spills.

Products & Services

• Raw material storage and silos: specially designed silos for safe, efficient storage of PVC resin, additives and other raw materials; customizable capacities and layouts.
• Pneumatic conveying systems: closed systems for dust-free transport of powders and granules; vacuum and pressure conveying options.
• Dosing and feeding systems: precision dosing units for multi-component formulations; automatic control and adjustable high-precision dosing.
• Process automation: integrated control systems for monitoring and managing feeding and conveying processes in real time.

The Importance of Extruder Central Feeding

• Increased productivity: automatic feeding enables continuous operation and higher throughput.
