Hot melt adhesive is not cheap and you may notice that the prices are only going up. What purchasing agents might not know, is that a lot of packaging lines are using more glue than is actually needed. There are a few simple ways to manage your actual glue usage and help cut costs to manage your budget.
The first step in managing your glue usage, is knowing the diameter nozzle tip you are using in your packaging lines, and understanding why you are purchasing that size. A lot of times, our sales reps will get calls from customers that want to buy larger size nozzle tips because their line operators are saying there is not enough glue being released on the cartons. Obviously, as you increase your nozzle tip diameter, the more glue you are going to use overall and increase your yearly costs for adhesive. This can also cause several other issues, such as potential sealing issues if the hot adhesive does not have enough time to dry as it moves along the cartoner. If your line operators are asking for larger diameter nozzles, question them as to why.
If your line operators are stating that the glue is not keeping the packaging closed, which is why they need larger nozzles, evaluate your setup. Check the distance your gun applicator is to your carton and at what temperature you are heating your adhesive. If the adhesive is not hot enough and your gun is too far away from the application site, the adhesive could be cooling before it even hits the carton which is why it is not creating a tight seal. Simply increasing your heating temperature or moving your gun applicator closer to the end application site could solve this issue. You could also be putting down too much glue already. If you have a high-speed packaging line, and put down too much glue, the speed will not allow time for the large amount of glue to dry.
Change Your Filters
Another simple solution to managing your glue usage, is to check both your tank and gun filters. If your nozzles are clogging frequently, causing the line operators to buy larger diameter nozzles, they may be clogging due to char. Char is a typical occurrence in hot melt packaging, but the transfer of most char can be prevented by regularly changing your tank and gun filters. These filters will extend the life of both your modules and nozzles.

Since Universal Systems SE offers technical support for all of our customers, we get several calls per day with all different kinds of technical issues that line operators experience. Because many packaging lines run 24/7, without regular maintenance of key products there will always be issues after a certain period of time. As always, we recommend changing your filters, nozzles and modules when needed to eliminate any potential issues. However, there may be other parts on your packaging lines causing these issues.
For example, if you are experiencing a dripping or not fully functional module, it is most likely not an issue with the module itself. Especially since all products go through a vigorous quality control process before leaving our facility. Because the modules are air open and spring close, there are a few items to check before switching out the module. First, Universal Systems SE recommends that you check the solenoid valve. The solenoid valve is the air supply that runs into the applicator gun and fires the glue onto the box. If the solenoid valve fails, it will not generate air power to fully open the module. If the solenoid valve is weak, it will not fully exhaust all of the air out of the module, and the module piston will not seat properly, causing a drip. Another potential issue could be that char or debris has been transferred from the tank into the gun and has gotten stuck in the spring close. This piece of char, no matter how small it could be, can limit the spring from fully closing causing “dripping”. Spring tension on the gun module being set too low could also cause “dripping”, so make sure you try to adjust that before switching out modules. Finally, if the line operator has not gone through the correct steps to change out the module, the module could be compromised. The line operator needs to make sure that they lower the air pressure used on the tank before switching modules. If they do not, they could potentially send glue into the air chamber of the gun when removing the old module.
Another common technical issue is that the heated hoses are either not heating or not heating to the correct temperature. The first step is to check and ensure that the hose zone is not set to “off”. If it is, turn the hose zone to “on”. Then, you should check to make sure all connectors are securely tightened and the controller settings are correct. If all of those are working, you next need to check the ohms reading on the hose heater and hose RTD, and all of the board fuses. A USSE technical support representative can walk you through this check process and help identify the real issue.

There are several things that can cause a piston pump to stop working. The most common reason is that it is clogged. Unfortunately, not all line operators take the time to close the lid on a glue tank. With a lot of carton dust in the air at any facility, this dust gets into the glue pot and melts in with the glue. When the pump shifter runs to pump the glue from the pot into the hose, that carton dust gathers around the pump which can cause it to seize. The simple solution to this is to make sure that all shift line operators are diligent about closing the tank covers, that’s why they are on there.
If carton dust is not your issue, and the pump fails, below are a few other possible causes and the corresponding solutions.
- Adhesive not sufficiently heated – check the tank temperature and required melt temperature of your adhesive and set accordingly.
- Inadequate or no input air to pump – increase the air pressure from the plant air supply and see if the pump will run.
- Dry running – when a tank drops below a certain adhesive level in the pot, the pump does not have enough glue to operate at full capacity. The glue that runs through the pump acts as a padding so that the shifter does not pound against the top and bottom of the pump itself. When that padding is less, the pounding shifter can cause damage to the magnets and create an issue with the shifter. The only solution to this is to get a new shifter and potentially invest in an auto fill on-demand system that fills the glue into the tank for you, leaving less pressure on the line operators to fill the pot.
- No Tank Screen or Clogged Tank Screen – the tank screen lives at the bottom of the tank and is the first line of defense against any foreign debris getting into the pump. Sometimes the tank screen gets removed or never cleaned. That can cause debris build up and seize your pump. It is easily cleaned by lifting out of the empty tank and then cleaning the tank with Purge Plus™.
- Clogged Tank Filter – the tank filter screws into the side of the tank and filters the glue after it leaves the tank. If the tank filter is clogged, then the adhesive will back up in the pump, causing the pump to seize.
- Pump solenoid is not on – if the tank is not within 35 degrees of the setpoint temperature on the control panel, the pump solenoid will not turn on. Check the setpoint temperature and make sure it is correct. If the setpoint temperature is correct and reading properly, then it might be a failed solenoid that needs to be replaced.
If you go through all of these troubleshooting steps and still have an issue with your pump, please call (561) 272-5442 or email firstname.lastname@example.org.
Hot melt adhesive application nozzles, or nozzle tips as they are commonly called, are the component that apply the glue onto boxes in packaging lines. Universal Systems nozzles are made out of brass with stainless steel tips to withstanding any beating they might take from box flaps in the packaging line.
Nozzles comes in many shapes and sizes, and are usually the part on the adhesive system that is most experimented with. Most nozzles are easily changed out by simply unscrewing them from the module. Other nozzles, like the ones on reduced cavity, zero cavity and ProBead modules are called integrated nozzles. We sell replacement nozzle kits for integrated nozzles that include the nozzle tip, needle, brass needle guide and installation tool.
The diameter of the nozzle tip determines the amount of adhesive that is distributed onto the box flap. Because you can easily switch them out, most line operators experiment with diameter to enhance productivity. For example, smaller, more precise glue application will require a smaller diameter nozzle. Larger, faster cartoners, will most likely run larger diameter nozzles to distribute a greater amount of glue and quickly seal boxes. Keep in mind that the larger the diameter nozzle, the more adhesive your tank will process. So make sure that your line operators are keeping a close eye on the adhesive level in the tanks. Dry running a machine can compromise your pump and create a costlier repair.
Because most adhesive systems run 24/7, the nozzle is the most commonly clogged component on your line. This is due to char or debris travelling from the tank, through the hose, into the gun and through the module. Because the nozzle is the smallest orifice on your system, most char will get stuck and you will be unable to get a consistent adhesive flow. Universal Systems SE offers nozzle cleaning kits that you can purchase instead of replacing nozzles. However, most line operators find the cleaning of nozzles a tedious process, even though when done correctly it works. Nozzle cleaning kits can save you money in the long run on replacing nozzles.
Another important aspect of nozzle diameter correlates to the size of the mesh in-line filter used on your system. The larger the diameter nozzle, the lower number mesh you should use. The smaller the diameter nozzle, the finer mesh you should use. For example, with a .024 diameter nozzle, you should have a 50 mesh filter size. With a .012 diameter nozzle, you should use 200 mesh filters.

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.
