RFID in Manufacturing: Benefits, Uses, and How It Works

Manufacturing moves fast. The bigger your factory, the more difficult it is to track. RFID in Manufacturing comes in here.

It follows materials, parts, tools, machines, and finished goods in your factory.

This guide will teach you the functionality of RFID in Manufacturing. You will also get to know where to apply it and why it is beneficial.

What Is RFID in Manufacturing?

RFID in Manufacturing refers to the application of RFID technology within a factory. RFID is an abbreviation of radio frequency identification. It is a radio wave-based method of identifying and tracking items.

You can track raw materials, parts, tools, equipment, pallets, containers, and products. Every product receives an RFID tag. There is a special code on that tag. Batch number, item status, date, or location can also be stored in some tags.

An RFID reader reads the tag when the item is in motion. The data is sent to your software by the reader. Your system updates the item record.

You do not have to go through all items manually. It is easier to keep track of numerous items.

How RFID Technology in Manufacturing Works

The RFID manufacturing technology operates in a straightforward flow.

1. You attach an RFID tag to an item.

This product can be a raw material, a part, a tool, or a product.

2. The RFID tag is scanned by the reader.

Radio signals are sent by the reader. It also gathers information on the tag.

3. The antenna assists in transmitting the signal.

The antenna assists the reader to connect to the tag. It also assists in getting data in a clear manner.

4. The data is sent to the software.

The item record is stored in the software. It also updates the status of items.

5. Your system is real time updated.

As an illustration, raw materials are received in your factory. A reader reads the tags. Your stock account is updated immediately.

6. You follow the object in motion.

As materials are transferred to production, they are scanned by another reader. Their new location is indicated on your system.

This provides you with a clear picture of your factory flow.

Types of RFID Tags Used in Manufacturing

RFID tags do not all operate in a similar manner. The correct option is determined by what you monitor and where you apply it.

Passive RFID Tags

The most common type is passive RFID tags.

They do not have a battery. The RFID reader signal provides them with power. Passive tags tend to be cheaper than active tags.

They are effective with stock, parts, boxes, pallets, and containers.

Active RFID Tags

Active RFID tags contain a battery.

They are able to transmit signals over greater distances. This renders them applicable to big assets and moving equipment. Active tags are more expensive than passive tags.

You can use them on cars, heavy tools, machines, or valuable equipment.

Sensor-Based RFID Tags

Location is not the only thing that can be tracked by some RFID tags. Sensor tags may be used to track temperature, moisture, movement, or other parameters.

These labels come in handy when the condition of the products is important. You can use them as food, medicine, or sensitive materials.

Choosing the Right RFID Tag

The optimal RFID tag will be based on your factory requirements. Consider the item surface, reading range, heat, moisture, metal, and cost.

Always check the tag prior to full use. This will assist you in avoiding weak reads.

Common RFID Applications in Manufacturing

RFID uses in manufacturing include numerous everyday activities.

Inventory Management

RFID provides you with a clear picture of your inventory. You are able to see what you possess and where it is. You are also able to see the time every item moves. This will assist you in preventing stock-outs and overstocking. It also speeds up cycle counts.

Work-in-Process Tracking

Work-in-process tracking refers to the tracking of items in the production process. RFID indicates the current stage of each item. You are able to detect delays more quickly.

Production Line Tracking

RFID assists in transporting the correct part to the correct station. This is important when you produce numerous types of products. The tag is able to inform the system of what each part requires next.

Tool and Equipment Management

Factories utilize numerous tools, molds, machines, and returnable containers. RFID simplifies their location. It also aids in loss and misuse prevention.

Quality Control and Traceability

RFID assists you in tracking every product during production. You are able to associate a product with a batch, material, machine, or process step. In case of a defect, you can locate the source more quickly.

Supply Chain and Logistics Tracking

RFID is able to trace materials of suppliers to your factory. It is also able to monitor completed products before delivery. This aids in minimizing lost products, incorrect deliveries, and manual inspections.

Benefits of RFID in Manufacturing

The benefits of RFID in manufacturing can affect many parts of your factory.
