Screw and Nut Counting Packing Machine

Many hardware manufacturers still rely on manual counting when packing screws, nuts, washers, bolts, and other small components. As production volume grows, manual packing becomes time-consuming, labor-intensive, and difficult to keep consistent. Missing parts, extra pieces, or mixed items can lead to customer complaints, product returns, and additional labor costs.

A Screw and Nut Counting Packing Machine automates the counting and bagging process for screws, nuts, bolts, washers, plastic anchors, and other small hardware parts. The machine counts each item according to preset quantities, combines different components when required, and seals them into bags automatically. Depending on the product size and packing requirements, the output typically ranges from 20 to 80 bags per minute. It is suitable for hardware manufacturers, furniture fitting suppliers, electrical component factories, automotive parts producers, and companies that package hardware kits for e-commerce.

How Does a Screw and Nut Counting Packing Machine Work?

The machine begins by feeding each type of hardware through its own vibratory bowl feeder. The parts move to the counting unit, where sensors count each item according to the programmed quantity. Once all components reach the required count, they are released into the packaging bag at the same time. The machine then forms the bag, fills it with the counted parts, seals it, and discharges the finished package. For mixed hardware kits, multiple feeding systems operate simultaneously so different components can be packed together in a single bag.

Why Choose Automatic Counting Instead of Manual Packing?

Key Benefits

Automatic counting helps reduce manual handling during the packing process while maintaining consistent quantities in every package. The machine supports both single-item and mixed-item packaging, making it suitable for different hardware kits. Multiple packing recipes can be stored on the touch screen, allowing operators to switch between products with minimal setup. This makes the machine suitable for manufacturers handling both standard production and customized orders.

What Hardware Products Can It Pack?

Screws

Self-tapping screws, machine screws, wood screws, stainless steel screws, and similar fasteners.

Nuts

Hex nuts, flange nuts, lock nuts, and other standard nut types.

Bolts

Hex bolts, socket head bolts, carriage bolts, and flange bolts.

Washers

Flat washers, spring washers, square washers, and related products.

Plastic Components

Plastic anchors, wall plugs, clips, and inserts.

Other Hardware Parts

Rivets, pins, furniture assembly fittings, and other small metal accessories.

Supported Packaging Combinations

The machine supports both single-product packaging and mixed hardware kits. For example, one bag may contain four screws, four nuts, and four washers, while another may include two bolts, two plastic anchors, and two washers. Different feeding bowls count each component separately before releasing them into the same bag. This configuration is commonly used for furniture assembly kits, electrical installation kits, and repair hardware sets.

Industries Using Screw Counting Packing Machines

Screw counting packing machines are widely used in furniture hardware manufacturing, door and window hardware production, construction hardware, electrical component assembly, automotive parts manufacturing, bathroom accessories, lighting components, hardware kit packaging for online retail, and fastener production. Any business that requires fixed quantities of small hardware parts can benefit from automated counting and packaging.

Technical Specifications

Optional Configurations

The machine can be equipped with additional functions based on production requirements, including a date coder, label printer, metal detector, finished product conveyor, automatic collection system, customized vibratory bowl feeders, multi-bowl feeding systems, and vision inspection modules.

How to Choose the Right Counting Packing Machine

When selecting a counting packing machine, consider the types of products, the number of items per bag, product dimensions, daily production capacity, and bag size. A single feeding system is suitable for packaging one type of product, while mixed hardware kits require multiple feeding bowls. Manufacturers producing different product sizes or handling frequent order changes may prefer machines that allow multiple parameter settings to be saved for quick changeovers.

Frequently Asked Questions

Q1: How much does a Screw and Nut Counting Packing Machine cost?
