What is Wire Crimping?

Are you scratching your head wondering about what is wire crimping? Then read this guide that discusses a lot about wire crimping.

In fact, you will rarely find an area where wire crimping is not used. From internet connections to the electrical connection of your office and home, the wire crimping process is used everywhere.

We looked into an in-depth discussion about wire crimping in this guide so that you can pick the right wire crimping tool according to your purpose.

Let’s begin.

What is Wire Crimping?

What is Wire Crimping

The straightforward answer to the headlined question is – wire crimping is used to join to pieces of metal.

It is when a crimping tool supports a connector to join a cable or wire.

Crimping is a widely used process for squeezing a terminal to a wire conductor without soldering. A crimp creates an exceptionally significant connection with the proper crimping process that withstands corrosion, liquids, and gas.

What Are the Types of Wire Crimping Tools?

A wide range of wire crimping tools is available in the market. Each type is used for specific purposes and comes with PROS and CONS too.

Crimping thicker wires is quite challenging because they require heavy force to crimp, while thinner wires don’t need much pressure. Let’s look at the different types of wire crimping tools from below.

Types of Wire Crimping Tools


Handheld wire crimping tools are the most commonly used and popular in the market. Also, they possess the simplest design. These are operated manually and ideal choice for small and thin wires. They are lightweight and easy to carry.

Some handheld wire crimping tools are multi-purpose featured, and you can use them for both wire cutter and stripper. A few models can be utilized to pull, loop, or grip wires together.


When you require more pressure to a thick wire, choose a hydraulic wire crimping tool to get the best result. They provide more pressure compared to handheld wire crimping tools. These tools are ideal for accomplishing industrial projects. Providing more pressure is not a challenging task for hydraulic wire crimping tools Since they use hydraulic fluid to provide pressure.

These tools have a downward. They can get clogged if oil maintenance doesn’t happen periodically because they run with hydraulic fluid. With proper care, they are the best wire crimping tools among the other 2 types.


Hammer crimping tools are wallet-friendly, and the working process is similar to its other elder brothers. The only difference is that it requires being placed on a flat surface and using a hammer to perform. Ideally, the wire end is placed between an anvil and a dye and is hit by a hammer so that the crimp gets made.

These crimpers are efficient in terms of their responsibility and can crimp thicker wire than handheld crimpers. They are bulky, and carrying them to the job site is impractical.

What are the Advantages of Wire Crimping?

Undoubtedly, crimping offers numerous benefits. You may need to co-joint several wires in electrical projects, internet cable connection projects, and many more. At this point, wire crimping is the best solution. When you need a highly reliable connection between 2 wires, wire crimping offers a reliable result.

The truth is, if you are an internet service provider or electrician, then you know that without wire crimping, you can’t run your business efficiently.

  • Wire crimping is a simple process that can be done either manually or automated machine
  • Once you make a crimp connection, a tight seal gets created between the cable and connector; finally, you are getting a long-lasting connection.
  • It offers a reliable connection that withstands the different environmental conditions such as dust, dirt, moisture, and sand.
  • The connection becomes extremely durable “cold-weld” when a skilled technician is in the supervisor of a crimping process.

What are the disadvantages of Wire Crimping?

Wire crimping also has a few disadvantages that can be overturned easily.

  • A reliable wire crimping is only possible when an experienced technician does it
  • Wire crimping tools are highly sensitive.

What Important Things Do I Need to Follow in Wire Crimping?

To get an effective outcome from the wire crimping process, it is significantly essential to follow the below things.

1# Selecting the correct wire gauge is crucial in the wire crimping process. Wire gauge diameter follows the standard system of AWG (American Wire Gauge).

2# Crimp terminal is another critical factor that needs to follow. Get the answer to the below 3 questions.

  • Wire crimping in the terminal will be necessary for low contact resistance or preventing corrosion or both?
  • Does pre-insulation require a terminal?
  • What is the ideal turn pin for the terminal?

3# A wide range of crimping tools is available, and each varies in terms of purposes. Select the right one according to your wire crimping requirement.

4# After determining the wire gauge, terminal, and tool, you must follow the proper wire crimping process.

5# Heat-shrinking is an essential process of wire crimping, and for this, you will require a heat gun. During heat-shrinking, make sure the sleeve is covering the wire and crimp perfectly. Avoid covering the terminal end at this process.

Frequently Asked Question

Is wire crimping better than soldering?

Answer: When you need to co-join wires, wire crimping offers an effective outcome than soldering. Wire crimping provides an airtight seal that protects the connection from moisture, dust, and dirt.

What is the alternative to a wire crimping tool?

Answer: You can continue your wire crimping project without an RJ45 crimper or specialized wire crimping tool. Using pliers, you can complete wire crimping.
