Máquina automática de embalagem de produtos de ferragens
Automatic hardware packing machine for screws, bolts, rivets, and small metal parts. Vibratory bowl counting or multi‑head weighing, puncture‑resistant bagging, PLC control, 20‑40 bags/min. Ideal for fastener distributors and hardware manufacturers.
Automatic Hardware Pouch Packing Machine for Small Metal Parts
The automatic packing machine for hardware products is a versatile and high-speed device that processes and packs small metal items, fasteners, and all hardware items into durable plastic pouches. The machine uses a high precision vibratory bowl feeder or a multi-head weigh system, ensuring accurate count and dose of parts such as screws, bolts, rivets, and small metal pieces found with MCBs. The machine has a heavy-duty film feeding system to produce heavy-duty, puncture resistant plastic pouches to keep heavy or sharp edged metal parts secure. With a user-friendly PLC touch screen, an operator can easily change the bag size and packing speed. This complete system optimizes your production line, reduces material waste, and greatly increases the efficiency and consistency of your packaging process.
There are two configurations supported by the machine: pre-made pouches and form-fill-seal (FFS). Applications for this equipment include hardware manufacturing, distributor of fasteners, and packaging of electrical components. Bag output typically ranges from 20 to 40 bags per minute depending on product size and bag dimension. There are also several optional features available for this equipment; for example: date and batch coding, auto bag openings, and conveyor integration for downstream cartoning.

What is a Hardware Automatic Packing Machine?
A hardware automated packing machine is specifically designed for packaging small metal parts, such as screws; nuts; bolts; washers; rivets; and electrical terminals. Unlike general-purpose bagging machines, this type of machine can handle sharp, heavy, or rough items without damaging the packaging material. The majority of machines use either a vibratory bowl feeder or a combination of weigh heads (multi-head) to accurately count or weigh an amount of part(s) before forming a bag from roll film (or using pre-made pouches) and filling, sealing, and optionally printing the batch/lot information onto the bag before it is finished. Each machine has reinforced jaws for sealing and is built with puncture-proof film handling to reduce the chance of packages breaking open. As a custom (non-standard) solution, the feeding system; the range of bag sizes will be custom-built to match the specific part dimensions; and the sealing method selected based on production requirements per day (output).
Vibratory bowl feeder for counting or multi‑head weigher for weight‑based dosing.
Reinforced film feeding and sealing for sharp or heavy metal parts.
Easy adjustment of bag length, filling speed, and batch count.
Inkjet or thermal transfer printer for lot traceability.

Principais vantagens técnicas
Robust feeding for irregular parts
Unlike conventional packaging machinery, which can have problems with sharp/irregularly shaped metal pieces, this equipment utilizes a vibratory bowl and specialized tooling, which provide the capability to orient/count screws/bolts/rivets without getting stuck. The multi-head weigher feature allows for rapid weight-based dosing of mixed sizes.
Puncture‑resistant bagging technology
Sharp edges may damage or destroy bags. To avoid this, the machine features a reinforced film-feeding system and a set of smooth, polished jaws that seal pouches together. Additionally, thicker films (up to 120 microns) can be used for heavy parts without causing the pouch to break during use.
Quick changeover for different part types
The recipe storage feature on the HMI enables operators to switch from one hardware item (e.g., M4 screws to 8mm washers) to another within five (5) minutes or less. The feeder tooling and bag forming system utilize quick-change components, which help to reduce the amount of downtime experienced by operators.
Integrated traceability for quality control
Either an optional inkjet printer or an optional thermal transfer printer, capable of adding lot number, date and batch codes directly onto each pouch, is necessary for hardware distributors & OEM’s and provide full traceability as required by the end-user.
Customer Success Story – Fastener Distributor
A big distributor of fasteners used to package screws and bolts by hand (the process was slow and time consuming, as well). However, since installing a hardware packing machine with a multi-head weigher and a film feeder capable of providing an uninterrupted supply of puncture resistant film, the distributor reported:
The machine paid itself back in nine months, allowing the client to manage peak season demand without the need for overtime.

Perguntas frequentes
Vibratory bowl counting is ideal for parts with uniformity and exact counts (for example, 50 screws/bag). On the other hand, a multi-head weigher is suitable if you are working with parts that come in varying sizes or if your pricing is based on weight (for example, you need 200g of mixed hardware). We will recommend which method is the most appropriate for your products and the precision required.
Indeed, the vibratory bowl can be equipped with miniature tracks for parts measuring down to just 2 mm in size. Likewise, a multi‑head weigher also works for tiny aspects; however, it must have a vibration control within close parameters to limit excessive product feeding.
Certainly! It is possible for the device to utilize pre-established pouches, provided from a magazine, or form a bag from a flat sheet of plastic, while also having the ability to print on the fly using an optional inkjet printer.
For the majority of products, the changeover time with HMI’s recipe system and quick change feeder tooling usually ranges from 5 minutes to 10 minutes.
The heat sealing method has variable temperature and pressure options. For very heavy components like a pack of bolts, weighing ~500 grams, impulse sealed combined with reinforced jaw design provides a sealing strength of >80% of the tensile strength of the film.
