Central Feeding and Automatic Weighing Feeding System for Plastic Extrusion Compounding Factories

Toolant’s Centralized Feeding and Automatic Weighing System is built for today’s push toward intelligent factories. This setup streamlines plastic compounding from start to finish—raw material handling, weighing, mixing, pelletizing, and packaging—all tied together with a PLC control system. With years of expertise in automated manufacturing, I’ll walk you through what makes this system a powerhouse, its standout features, and how it fits into modern production lines.

This system runs on a closed-loop PLC framework. Raw materials—powders, granules, or liquids—move from storage through a centralized feeding setup to precise weighing stations. The PLC tracks and adjusts everything in real time, feeding materials into twin-screw extruders for compounding, then onto pelletizing and final weighing for packaging. It’s a seamless flow, cutting manual steps and keeping output steady. Production capacity spans 1-5000 kg/h, so it scales from small batches to full-scale runs.

Here’s what drives its performance:

• Centralized Feeding: Handles powders, granules, and liquids with flexible conveying and storage options. It adapts to your material mix and feeding style.
• Weighing Precision: Loss-in-weight feeders hit ±0.5% accuracy, using sensors to tweak discharge rates on the fly.
• PLC Control: Ditches outdated microcomputers for fast, interference-free signals, syncing with upstream and downstream equipment.
• Self-Diagnostic Tools: Spots and fixes deviations during operation, keeping accuracy locked in without downtime.

A 2023 Plastics Technology article flagged automated feeding systems like this as cutting material waste by up to 20%—our setup delivers on that promise.

This system brings practical wins:

• High Output: Speeds up production with coordinated automation, hitting up to 5000 kg/h for big jobs.
• Low Costs: Fewer workers, less waste, and tight control over materials shrink operating expenses.
• Consistent Quality: Real-time adjustments ensure every batch matches your specs.

A rubber compounding plant using this system reported a 15% drop in labor costs and tighter pellet uniformity, thanks to the PLC’s precision.

It’s designed for plastic modification and compounding—think PE blends, TPE pellets, or reinforced PP. Whether you’re in plastics, rubber, food, or pharma, it handles:

• Small runs at 0.5 kg/h for testing formulas.
• High-volume production at 10,000 kg/h for full-scale output.

The flexibility covers hundreds of process routes, matching your material types and ratios.

Key technologies powering the system:

• Accurate Metering: Weighing sensors feed data to the PLC, adjusting screw speeds instantly for spot-on material ratios.
• Self-Recovery: Built-in diagnostics catch and correct errors, like a feeder drifting off target, without stopping the line.
• Wide Range: Scales from 0.5 kg/h to 10,000 kg/h, adapting to any production need.

Take a plastics recycler: The system’s real-time tuning kept their HDPE blend within 0.5% of target, boosting pellet quality for resale.

The hardware—feeders, conveyors, and mixers—pairs with a PLC that’s fully compatible with your existing setup. It’s low-maintenance: check sensors, clear conveyors, and you’re set. A 1-year warranty covers the lot, ensuring reliability. The anti-interference design means no signal lag, even in busy plants.

This isn’t just equipment—it’s a step toward a leaner, smarter factory. High efficiency, low costs, and consistent output make it a solid investment. A food-grade plastics producer using it cut material overruns by 10%, proving its value in real-world conditions.
