Automatic fastener packaging systems are designed to weight, count, and pack a wide range of fasteners, such as screws, nuts, bolts, and washers—with high speed and impeccable accuracy. Whether you pack small batches of specialized items or large volumes of standard fasteners, we have a system to automate your future.
Fastener packing is a specialized field because it involves counting and handling a large number of small, heavy, and often irregular items (like screws, nuts, bolts, and washers) at high speeds. The primary goal is accuracy and efficiency.
The main categories of fastener packing machines can be broadly classified into two types:
-By Counting & Weighing Principle
-By Type of Package Produced
----------------------------------------------------------------------------------------------------------------------------------------------------
1. By Counting & Weighing Principle
A. Fastener Weighing Packing Machine
These machines use high-precision scales to measure the product by weight. They are the most common and versatile type.
How it Works: The machine's control system knows the average weight of a single piece (e.g., one screw). It then calculates how many pieces are needed to reach the target count (e.g., for 100 screws, it targets 100 x unit weight). Product is fed into a bulk hopper and then dribbled into a weigh bucket until the target weight is achieved.
B. Fastener Counting Packing Machine
These machines use sensors (often optical or laser) to count each individual piece as it passes by. They are the gold standard for high-speed, high-accuracy counting.
How it Works: Fasteners are singulated and fed down a chute or past a vibrating tray. As each piece passes a sensor, it is counted. The most advanced systems use multi-beam lasers or cameras to ensure no double-counting or misses.

2.By Type of Package Produced
A. Bagging Machines
These are the most common type, packing fasteners into plastic bags (poly bags) or laminated pouches.
How it Works: A flat roll of film is formed into a tube, filled with the counted fasteners, and then sealed and cut into individual bags. They are very efficient and can print batch codes, dates, etc., directly onto the bag during the process.
B. Box/Case Packing Machines
These are used for larger bulk quantities, typically for industrial customers.
How it Works: Fasteners are counted by weight or electronically and then deposited into corrugated cardboard boxes or cases. This can be a semi-automatic process where an operator holds the box under a chute, or a fully automatic system that erects, fills, and seals the boxes.
