1. Introduction
In modern manufacturing, efficiency and precision are essential. For industries dealing with screws, fasteners, and small hardware components, manual packaging is no longer viable due to labor costs and error rates. This is where the automatic screw packing machine comes into play. It is designed to automate the process of counting, bagging, and sealing screws, ensuring accuracy, speed, and cost savings.
2. What Is an Automatic Screw Packing Machine?
An automatic screw packing machine is a type of industrial equipment that counts, sorts, and packs screws or other fasteners into pre-set quantities. It replaces manual labor, ensuring consistency in packaging while reducing waste and errors.
3. Working Principle of Screw Packing Machines
The machine integrates automatic counting, bag forming, filling, sealing, and optional labeling.
3.1 Counting System
Uses photoelectric sensors or vibration plates to count screws precisely.
Can handle 1–4 types of screws in one package or single-type bulk packaging.
3.2 Bagging Process
Automatic bag forming or feeding of pre-made bags.
Adjustable bag sizes (commonly L50–300mm, W50–200mm).
3.3 Sealing Mechanism
Heat sealing ensures strong and durable packaging.
Optional gusseted bags for bulk packaging.
3.4 Optional Printing and Labeling
Can integrate date coding, QR codes, or barcodes.
Custom labeling for retail-ready packaging.
4. Key Features and Benefits
High Accuracy: Error rate <0.1%.
Flexibility: Can pack screws, nuts, bolts, washers, plastic parts.
Efficiency: Reduces labor cost by 60–70%.
Customization: Supports multi-language interface and custom bag design.
5. Common Applications in Industrial Production
Furniture industry: Packaging screw kits for flat-pack furniture.
Construction hardware: Bulk packaging of bolts, nails, and anchors.
Plastic and rubber parts: Used in automotive and electronics.
6. Case Study: Improving Efficiency in a Fastener Factory
A fastener manufacturer in Europe replaced manual packing with a Feiyu screw packing machine. Results:
Labor cost reduced by 65%.
Daily output increased from 50,000 to 120,000 packs.
Consistency in package weight and quantity improved customer satisfaction.
7. Factors to Consider Before Purchasing
Packaging size requirements
Number of screw types per pack
Speed and output capacity
Integration with existing production lines
After-sales service and support
8. Maintenance and Troubleshooting Tips
Regularly clean sensors and vibrating plates.
Check sealing temperature to avoid weak seals.
Replace wear parts (belts, heating wires) on schedule.
Keep spare parts in stock to minimize downtime.
