How Industrial Glue Guns Are Used

You may be familiar with hot glue guns from your high school home-economics class. You may remember weird, cylindrical, solid-but-flexible, sticks of translucent glue that you placed into a small hot glue gun. The gun would heat the glue, and you could use the hot glue to adhere pieces of fabric together (or to make other craft projects).

Hot glue also has the name of hot melt adhesives, which is the term typically used in industrial settings (or just “hot melt” for short). Indeed, what you may not know is that hot glue has many more uses than craft projects. Many industries use hot melt as part of the manufacturing and assembly process.

In industrial settings, you are doing a lot more than sticking fabric together. Industrial hot glue is used for many different and sometimes precision jobs for various industries. For these bigger jobs, companies require industrial glue guns and products. These are not your little, home-economics-style, glue guns. These are bigger, with more power and more capability.

Let’s learn more about the industries that use hot melt, how it is used and which types of hot melt are best for each job.

Hot melt or hot glue

Hot melt or hot glue is designed to be melted with a glue gun. This glue is sometimes called thermoplastic adhesive. Hot glue guns use continuous heating elements to melt the adhesive.

In industrial settings, industrial hot glue and industrial hot glue guns give many advantages over solvent-based adhesives or other fasteners. Industrial hot glue can dry strong and quickly, reducing the time delay before the product is ready. Hot melt also cures quickly. Industrial hot melt has a long shelf-life, and after use, it can be disposed of without any special precautions.

Hot melt also has the advantage of not losing any thickness when drying. This makes it especially helpful in some commercial projects (such as woodworking). There are many types of industrial hot melt and industrial hot melt guns to match different needs in various industries. There are even hot melt adhesives that can be applied by dipping or spraying.

Industrial hot melt has properties that should be considered for the specific job you intend it for. One of these is the bond formation temperature, which is the minimum temperature at which the adhesive can create bonds. In industrial settings, it is also important to consider the potential life stability, because the hot melt is often molten for longer time periods when working in industry.

The term tack refers to the stickiness of the hot melt. When you are working with industrial hot glue, you have a certain amount of time during which the hot melt is tacky before it sets. The open time tells you how long you can work to set a bond. The set time tells you how long it takes for the bond to form to an acceptable strength.
