What Is a Central Feeding System?
A central feeding system — also known as a centralized conveying system, central material handling system, automatic feeding system, or vacuum conveying system — transports plastic pellets, regrind, powders, and additives from a central storage area to multiple processing machines through a sealed vacuum pipeline network. It replaces standalone vacuum loaders and hopper loaders with a unified, plant-wide solution.
The system operates under a central HMI+PLC control platform, enabling one-to-many remote conveying, automatic material selection, and real-time monitoring. It is widely used in injection molding, extrusion, blow molding, and rubber processing plants that require stable, contamination-free material supply for automated production.
As a central feeding system manufacturer based in China, Streamline Eco Tech (CNHAO) provides turnkey central conveying solutions — from factory layout design and equipment supply to installation, commissioning, and after-sales support — for plastics processors worldwide.
Why Choose a Central Conveying System
- 24-hour continuous material supply for unmanned production
- 70% labor cost reduction — one operator manages the entire plant
- Scientific separation of raw-material and molding areas for cleaner factory layout
- Zero cross-contamination — sealed pipeline with “one machine, one pipe” design
- 5-10% material savings through reduced spillage and precise dosing
- Industry 4.0 ready — digital traceability, MES/ERP integration, remote monitoring

Why Automate Your Material Conveying?
Scientific Zoning
Separates raw-material storage from the molding floor. Zones raw materials, dust collection, and processing equipment for a cleaner, safer, and more efficient plastics factory layout.
Centralized Control
Single HMI touchscreen manages the entire centralized feeding system — material selection, conveying routes, drying parameters, and dosing ratios — eliminating human error and material mix-ups.
Frees Production Floor Space
Removes storage bins, gaylord boxes, and material bags from around molding machines — opening valuable floor space for automation, robotics, and auxiliary equipment integration.
Digital Material Management
Real-time tracking of material consumption, conveying history, and inventory levels. Supports smart factory data integration via OPC UA and Modbus TCP for full production traceability.
Materials We Handle
The central feeding system is suitable for a wide range of rubber and plastic materials, including recycled and auxiliary materials.
