There are several different set ups available for your hot melt application. That’s because not all industries use glue application for the same reason. The most common form of hot glue application is standard case packers for mass production high speed packaging. Typically, those lines use standard H200 modules. However, glue application is used to seal other, more specific products. For example, swirl pattern modules are used for glue application on feminine hygiene products, diapers and also for sealing air filters. This blog is going to specifically explain zero cavity modules and what industries use them and why.
Zero cavity modules have a very specific look, with a nozzle head attachment rather than a screw on nozzle. They also come with an E-Z Micro Adjust attachment to manage precision glue application. This nozzle & micro-adjust feature is custom manufactured for precise glue placement on smaller boxes, such as crayon boxes or pharmaceutical products. This unique technology allows for line operators to place a small amount of glue on a small, predetermined location without creating any stringing. Typically, because of this precise requirement, most zero cavity modules are made with either a .008 or a .012 diameter orifice, so that there can never be too much glue applied.
Because zero cavities have a matched piston needle and seat, when they finally wear out, most manufacturers require customers to replace the entire module. Universal Systems does not. We manufacture a rebuild kit specifically for zero cavity modules for a fraction of the price of replacing an entire module. Check out our rebuild kits here: https://www.ussefl.com/products/hot-melt-modules/module-rebuild-kits/.
Not many hot melt application manufacturers offer zero-cavity modules. Luckily, here at Universal Systems we have been manufacturing this specific module for over 25 years.

Modules, they are the most used product on your packaging line, yet so many operators don’t understand how they are constructed or when to replace them. Like an oil filter on your car, a hot melt module’s main job is to be the conduit for applying adhesive on your packages and should be replaced every 1,000 hours. Replacing a module is simple, and the part itself is fairly inexpensive, but not changing them out could lead to extremely expensive repercussions.
There are two different ways that hot melt can be pumped through the module. First, there is an air on, spring off module (AO/SC). This type of module is the most common in the packaging industry, and the easiest module type to replace. It works by the gun pumping air into the module, to open the flood gates and pump the adhesive through the nozzle, on to the packaging material. When the airflow stops, a spring inside the module closes the opening and stops the adhesive from flowing. The other type of module is an air open, air close (AO/AC). This is a less common type of module and patented by Nordson®. If your machine operates with an air open, air close module then the replacements will be more costly and harder to find. Essentially, this module operates with air pumping through the gun to open the flow of adhesive, and then uses an air intake from the side of the module to stop the flow of adhesive. Keep in mind, that if you operate using an air open, air close module, you can replace it with an air open, spring close module by bypassing the air intake line. However, you cannot run an air open, air close module on an air open, spring close gun.
O-rings are an important component on any module. These tiny ring-shaped seals keep your module from clogging up, increases the efficiency of your system and limits the downtime of your lines. When replacing modules on your guns, make sure that the o-rings are placed securely on the module. If they get clogged with glue, then your module will clog and become defective.
Another important point to note when learning about your module, is the type of nozzle it takes. Not all nozzles and modules are the same. For example, zero cavity modules come with an integrated nozzle seat which allows for a no drip, positive cut off of adhesive. Each zero cavity module needs to be ordered by diameter size. A standard H200 module, however, does not come with any nozzle. You need to order nozzle separately and they come in multiple orifice sizes.

By far, the most commonly asked question we receive is – what is the difference between a glue gun and a module? A misconception that many packaging line buyers make is that when a module fails, you need to replace the entire gun. That is not true. In most cases, the modules attach to the gun and can be easily removed and replaced.
Below is a breakdown of the components that comprise a hot melt adhesive gun application system:
- Gun Head – this is the gun body that attaches to the packaging line and initiates the application of melted adhesive into the module. There are a variety of different style gun heads, ranging from 1 module to multi module capacities.
- Module – the module attaches to the gun head via two screws. Each gun applicator will come with modules, but these can be replaced regularly once they get clogged. The module is the conduit that applies the adhesive to the package.
- Nozzles (not always included when you purchase a gun) – at the end of every module is a nozzle. Most standard nozzles will screw on to the end of the module. The diameter of the nozzle will determine how much hot melt is applied to each package. Some modules, such as reduced cavity, zero cavity and ProBead’s, will come with an integrated nozzle seat attached. Replacement kits for these integrated nozzles are sold separately, instead of buying a brand-new module.
If you only need to replace the module, and not the entire gun applicator, make sure you check which type of module you need. Below is a list of the most common modules in use today.
- Standard H200 Module
- ProBead Self-Cleaning Module
- Reduced Cavity H200 Module
- Zero Cavity Micro Adjust H200 Module
- Swirl Pattern Modules
- Weave Pattern Modules
- H20 Modules
