What is a Central Feeding System?
A central feeding system (also known as centralized feeding system or automatic feeding system) is an advanced automation solution designed specifically for plastic processing facilities. This intelligent material handling system automatically transports plastic raw materials from centralized storage areas to multiple injection molding machines, extrusion lines, and blow molding equipment through a network of vacuum conveying pipelines.
💡 Key Advantage: A properly designed central feeding system typically achieves ROI (Return on Investment) within 18-24 months through labor savings, reduced material waste, energy efficiency, and improved product quality.
OVERVIEW
Nicety Machinery Co., Ltd specializes in manufacturing centralized feeding and conveying systems for plastic raw materials (granules, recycled materials, and powders).
The purpose of these systems is to store, dry, and mix materials, and automatically transport them from a central silo to multiple processing machines.
How Does a Centralized Material Feeding System Work?
Raw materials are centrally stored, dried to the required moisture level, and then conveyed through a closed pipeline system to each production machine.
The system operates automatically and continuously, ensuring clean, efficient, and unmanned material handling.

What Are the Key Components of a Central Feeding System?
Central Control Station (PLC System)
The brain of the entire central feeding system, featuring Siemens or equivalent PLC controllers with large-format color touchscreen HMI. Manages feeding schedules, monitors material levels, controls dust collection, and provides alarm notifications. Supports up to 36 injection molding machines with expandable architecture.
Vacuum Conveying System
High-efficiency roots blower or vacuum pump generates negative pressure for material transportation. Conveys plastic granules and powders through stainless steel 304 pipelines up to 100 meters horizontal distance. Includes automatic cleaning cycles to prevent cross-contamination between materials.
Dehumidifying Drying System
Centralized honeycomb dehumidifier removes moisture from hygroscopic materials (PA, PC, PET, PBT). Achieves dew point of -40°C or lower with adjustable drying temperature from 40°C to 180°C. Integrated hot air circulation ensures uniform drying and material quality.
Material Distribution Station
Distributes raw materials from central storage silos to individual production machines. Features quick-coupling design for easy assembly and maintenance. Equipped with material selectors, cut-off valves, and pneumatic controls for precise delivery.
Storage Silos & Hoppers
Large capacity storage tanks (500kg – 10,000kg) with material level sensors and dust collection ports. Options include vacuum hoppers with magnetic reed switches and electric-eye hoppers for automatic feeding control directly mounted on injection molding machines.
Dust Collection System
Dual-stage filtration combining cyclone dust collectors and pulse dust collectors. Automatically removes dust and fines from raw materials during vacuum conveying, improving product quality and maintaining clean workshop environment.
Auxiliary Equipment
Includes gravimetric blenders for precise color and additive dosing, plastic crushers for regrind integration, metal separators for contamination detection, and proportional mixers for virgin/regrind blending.

What We Need to Quote Your Central Feeding System?
To provide you with an accurate and tailored quote for your central feeding system, we need some key details about your production setup. The more information you can provide, the better we can design a system that fits your needs perfectly.
How many machines will the system serve? This helps us design the material supply setup and calculate the required capacity.
What materials will you be processing (e.g., PP, PE, PET, engineering plastics)? Each material has different flow properties, which affect the conveying system design.
What is the desired production rate (kg/h or lb/hr)? This allows us to size the system for your throughput, including the proper selection of vacuum pumps, receiver sizes, and other components.
How far do materials need to be conveyed? Long distances may require additional pump capacity or specialized piping configurations.
Will you need an integrated dryer? Please let us know if materials require dehumidifying or hot-air drying before reaching the machine.
Will you be using silos, gaylord bins, or another type of material storage? This will help us determine the best material handling setup for your operation.
Do you need features like recipe management, dust collection, multi-material handling, or color change systems? Let us know about any specific requirements or challenges unique to your production.
Once we have these details, we’ll prepare a custom system layout and proposal, including equipment specifications, pricing, and lead time. If needed, we can also arrange a site survey to fine-tune the system design based on your plant layout and operational needs.
The FAQs About Central Feeding Systems
How much does a central feeding system cost?
The cost of a central feeding system varies based on factors such as:
System size & complexity (number of machines, distances covered)
Materials handled (e.g., PP, PET, engineering plastics)
Custom features (e.g., multi-material handling, recipe management, dust control)
Installation & support (training, warranties)
Typical Price Range
Basic systems start around $20,000, but more complex, customized setups can exceed $100,000 USD.
For a precise quote, contact us with your specific requirements.
How long does installation and commissioning take?
Typical installation timeline is 2-4 weeks for standard systems, depending on factory size and complexity. This includes: mechanical installation of pipelines and equipment (1-2 weeks), electrical wiring and control system setup (3-5 days), system testing and commissioning (2-3 days), and operator training (2 days). We can provide accelerated installation services for urgent projects. Installation is performed by our certified technicians with minimal disruption to ongoing production.
Can the system handle multiple different materials simultaneously?
Yes, advanced central feeding systems can manage 10+ different materials simultaneously. This is achieved through: dedicated pipelines for each material type (eliminates cross-contamination), sequenced delivery schedules using shared pipelines with automatic cleaning cycles, and material selectors that route specific materials to designated machines. The PLC control system coordinates all material flows to ensure the right material reaches each machine at the right time.
What maintenance is required for central feeding systems?
Central feeding systems require minimal maintenance compared to individual loaders. Regular maintenance includes: vacuum filter cleaning/replacement every 3-6 months (automated cleaning cycles reduce frequency), annual vacuum pump service (oil change, seal inspection), periodic pipeline inspection (visual check for wear), and silo level sensor calibration annually. Most systems include predictive maintenance alerts through the PLC system. Total maintenance time is typically 4-8 hours per year, far less than maintaining multiple individual loaders.
Is it compatible with my existing injection molding machines?
Central feeding systems are universally compatible with all major injection molding machine brands including Haitian, Engel, Arburg, Sumitomo, Husky, Nissei, Toyo, Boy, Wittmann Battenfeld, and others. The system connects to the machine's hopper inlet regardless of manufacturer. We provide custom mounting adapters and interfaces as needed. The system also works with extruders, blow molding machines, and other plastic processing equipment. During the design phase, we verify compatibility with your specific equipment models.
Can I expand the system as my factory grows?
Yes, our central feeding systems feature modular scalable design specifically for future expansion. You can easily add: additional storage silos for new materials, extra feeding points for new machines (PLC supports 50+ points), extended pipeline networks to reach new production areas, upgraded vacuum capacity for higher throughput, and enhanced control features for automation integration. We recommend designing initial systems with 20-30% overcapacity to accommodate near-term growth cost-effectively. Expansion typically requires only 2-3 days of installation work with minimal production disruption.
