Fully Automatic Counting & Bag Packaging The system integrates multi-channel counting with vertical bag forming, allowing various fasteners—such as nails, screws, bolts, and small hardware—to be accurately counted and packed directly into bags. This automation significantly reduces manual labor and improves production efficiency. |

Smart PLC Control With Easy Parameter Adjustment Equipped with a PLC + touch-screen interface, operators can quickly set or modify counting quantities, product combinations, and bag sizes. Recipe storage ensures fast changeovers when switching to different hardware types. |
![]() |
Auto-Stop & Alarm for Material Shortage The machine automatically pauses when materials run low and triggers an audible/visual alarm to remind operators to refill. This prevents empty bags, reduces downtime, and ensures production continuity. |

Integrated Coding & Printing System A smart date printer can automatically print product specifications, batch codes, QR codes, and company logos directly onto the bag, reducing the need for external labeling equipment and keeping the packaging workflow fully inline. |

| Case 1: Economic Benefits Brought By The Screw Packaging System | ||
| Take the "landpack" screw packaging system used by a certain manufacturer as an example. The factory originally used manual weighing and packaging, but after it was put into the screw packaging system, there were the following obvious changes. | ||
| Comparison Item | Artificial Weighing + Packing | After Using The Packaging System |
| Average Weight Deviation Of A Single Bag | ≤5g | ≤2g (Saved 3 grams) |
| Need Labor | 10 people | 3 people(Saved 7 Labor) |
