How Does A Glue Gun Work?

A glue gun is a hand-held hot glue gun filled with glue sticks. The glue inside the glue gun gets heated to a temperature below its evaporation point. This makes it into a liquid state easily dispensed through the nozzle. This temperature differs depending on different materials. This liquid melts when it comes in contact with plastics and then turns into an adhesive that keeps plastic parts together. It is a fast way to glue two pieces of plastic together and gives an even finish.

How to use a glue gun on plastic?

Understand a few ways to use a glue gun on plastic below:

1. Know Which Glue Gun and Glue Stick to Use:

There is a variety of glue guns available in the market. Choose one that fits your use. A hot melt glue gun is suitable for general use. Some new models come with temperature control so that you can adjust the temperature based on the type of plastic and material you use.

2. Make sure there is no leftover glue in the nozzle :

It is imperative to make sure that there is no glue remaining in the nozzle. You can do this by heating the glue gun and running a piece of paper through the nozzle. This will remove any glue that may be present inside the nozzle. You should repeat this procedure until the nozzle is clear of any leftover glue.

3. Place a glue stick inside the chamber of the glue gun :

Place a glue stick inside the chamber. Ensure that you place it appropriately. The chamber has a cap on the back of the gun. You can open the cap by pressing the button on its back. It also connects to a safety switch.

4. Connect the cord of the glue gun to a power outlet :

Connect the cord of the glue gun to a power outlet using an extension cord. Ensure the extension cord is long enough to reach your work table. It will make your work more accessible, and you can adjust the gun conveniently.

5. Hold out for the glue to warm up :

You can now begin using the glue gun. Hold out for a minute before using it because the glue needs to warm up. It takes about a minute for the air between the glue layers to heat up and become liquid. You will know when it is ready because some melted glue is leaving the nozzle.

6. Push the trigger sparingly to let the melted glue out :

Push the trigger of the glue gun to dispense a small amount of glue. A minimal amount will dispense at first and expand into a soft ball in seconds. You can dispense more giant globs of molten glue as you push the trigger. The effect becomes a rolling-out fondant that even coats the plastic.

7. Use only the necessary amount of glue :

Always use the minimum amount of glue necessary. Too much glue can ruin the material that you are trying to glue. It can make the material too heavy and can cause it to break. It can also be annoying to clean up the sticky mess. Use a glue gun sparingly and only where you are confident you need it.

8. Leave the glue to dry :

The dispensed glue will dry in just a couple of minutes. It may be necessary to hold the pieces together until the glue sets. You can then use clamps to hold the pieces together while they dry completely. It may be necessary to sand the edges of materials once they are dry. You can use fine-grade sandpaper for this job.

9. Have a glue gun nearby for simple repairs :

You can use a glue gun to do simple repairs when you want to fix or adjust something. It is far more convenient than using a glue stick to fix things. Just glue the problem areas, and all your repair problems get solved.

10. Always keep the nozzle clean :

You must ensure that the nozzle of your glue gun remains clean and clear at all times. You can remove any waste adhesive that might have stuck on it with a pin, and a cotton swab dipped in rubbing alcohol.
