This is most definitely a new reality that we are all facing. Never before have so many companies had to shut down several, if not all, of their packaging lines because of a global pandemic. However, it was a scary and necessary measure taken to prevent further outbreaks of COVID-19. Now, as we slowly start to reopen as a nation, so does our packaging facilities. State by state, Governors are rolling out the reopening phases that each company, both essential and non-essential must follow.
With the reopening happening, that may mean you are going to run into a few speed bumps. As we all know, machines that typically run seven days a week, don’t like being shut down for three months. Especially if they are not shut down and cleaned out properly before they sat around idle. So, when you switch the power button back to “ON”, everything might not turn green.
In an effort to help with troubleshooting, we have put together a quick list of potential fixes.
1. CLEAN YOUR TANK. We cannot stress this enough. Even if your team drained the glue in the tank reservoir before shut down, there will still be old residue that will impact your restart. Cleaning your tank is fairly simple. First, make sure to detach all guns from the hoses before running the cleaner through. Utilizing our Purge Plus cleaner, fill the tank reservoir and heat. Place the end of the hose inside a bucket and flush the cleaner through the tank and out through the hose.
2. CHANGE ALL FILTERS. This includes both the tank filter and in-line gun filter. Starting with new fresh filters is the smart way to go.
3. NOZZLES MIGHT GET CLOGGED UPON INITIAL RESTART. Nozzles have small orifices that dispense the glue onto packages. If there is any left-over char in the tank from restart, the nozzles could get clogged up first. Try switching the nozzle to see if that fixes the issue.
4. REBUILD KITS. There are a few items that can be rebuilt on your adhesive melter system. For example, your pump. If you think that your seals have dried up from sitting idle through the down time, and you have a skilled mechanic trained to work on the equipment, try ordering a rebuild kit. This will save you money on purchasing a new pump.
If you experience any other issues during your restart, please call us directly at (561) 272-5442 and a technician will walk you through troubleshooting any issue. Stay Safe!
Air quality is important in all aspects of life, but for some reason usually overlooked in packaging lines. Almost all hot melt application equipment will require air to operate, especially if they are pneumatic. Universal Systems’ line of ProBilt™ hot melt equipment utilizes air in several different points of operation. The pneumatic pumps require air in order to shift the actuator and pump the glue through the system. Also, modules require air to open the piston and, in some cases, even to close the piston. Of the two operations in your hot melt application process that require air, it is most important for the pump to receive clean air.
Universal Systems pneumatic pumps are manufactured with extreme precision and delicacy. The most important part of the pump is the actuator, otherwise known as the shifter. The shifter’s main components are the spool and sleeve, which is how the shifter “shifts”. The spool and sleeve are machined in pairs, hand measured, calibrated, cleaned and assembled. The shifter is attached to the side of the pump. If you have a ProBilt™ tank and pump, take a look at the label on the side of the shifter. It reads: “The air supplied to the pump should be dry, filtered and non-lubricated.” If the air supplied to the pump, that goes through the shifter, is lubricated, your shifter will seize over time. The reason is that the oil in the air will build up in the millimeters of space between the shifter spool and sleeve, not allowing it to smoothly shift. If you do have unfiltered air running to your hot melt pump, we sell a ¼ NPT filter regulator that you can attached to the air lines and filter the air before it goes into the pump. Check it out on our website here.
If you have any questions regarding your pneumatic pump or modules, please call us at (561) 272-5442 and one of Universal Systems’ technicians will be happy to help. You can also email firstname.lastname@example.org.
Have you ever purchased a case of soda or carton of coffee cups and can’t get the box open? Of course, we all have. In the packaging industry, especially for hot melt machine manufacturers, that is a red flag. Whenever we get a box that has too much hot glue on it means that the packaging line is not set up properly or not being cleaned regularly.
If you are wondering why too much glue means that the line is not set up properly or not being cleaned regularly it is because one of two issues is occurring (or sometimes even both). The first issue is most likely that the line operators and/or maintenance managers are not cleaning the tank regularly and the lines are clogging up with char, which will subsequently clog nozzles. Instead of cleaning the tanks and hoses, and replacing the tank filter and in-line gun filters, most operations just buy bigger nozzles. If the diameter of the nozzle orifice is larger, then it will allow through more bits of char and not clog up as easily. Unfortunately, this is not a long-term solution. Putting down more hot glue will drive up the amount that facilities spend on adhesive pellets, and ultimately the annoyance will trickle down to the consumer when they can’t get their box open. The solution is simple…utilize Purge Plus to clean your tank every 1,000 hours. For some facilities that could mean cleaning every quarter and for others that could be twice a year, it all depends on the facility. In addition to cleaning the tank and hoses with Purge Plus, make sure that the tank filters are changed every 500 hours. The in-line gun filters should be changed every 150 hours to ensure that no char travels into the gun applicator, through the module and nozzle and onto the box.
The second issue that could cause too much glue on boxes, is that the line was not set up correctly from initial purchase. A lot of cartoners have standard hoses, guns, modules and nozzles that will work for most case packers, but not for all. Make sure to take into consideration the temperature of your packaging facility (which can impact the adhesion and viscosity of the glue as it travels through the application process), the distance that the guns are to the box upon application, and the surface area of the box you are covering. The longer the bead of glue you place, the less likely you are to need a larger diameter nozzle. The shorter the range you are covering, you might need more glue to make sure that maximum adhesion occurs, which means you need a larger diameter nozzle.
If you think you are putting down too much glue on your packaging line and need help, call one of Universal Systems’ technicians at (561) 272-5442. We have the most knowledgeable technicians in the business that can help you with almost any question.
Case packing and sealing in packaging lines depends on several components to run steadily and reliably. In order for a system to run continuously at all times, each piece of equipment needs to be concisely installed. The usual suspects of precision engineering on your case sealer adhesive systems are the pump, applicators and nozzles. Most line operators undervalue the importance of heated hose length in the overall operation and efficiency of the line.
Heated adhesive hoses get attached to the hot melt tank and run from the tank to the application gun, which is mounted on the packaging line itself. Heated hoses are typically attached to the tank with a straight connector, but can have both a 45 degree or 90 degree connection option, depending on where the tank is placed on the line. The applicator plug at the end of the hose is also sent out as a straight connection, but can be switched to a 90 degree plug if needed. There are typically two – four hoses used on each packaging line. With a two hose line, one hose will run up the line, across the top and down to the applicators. This hose transfers the adhesive that will seal the top of the carton and is mounted using straps. The second hose will typically run straight along the side of the packaging line to seal the bottom of the case. No matter how many hoses you run or how you mount them, it is very important to have the correct length hose.
Our technicians visit several packaging facilities each year, and their biggest take away is that most purchasing agents are ordering the wrong length hose. Typically, the hoses that we see are too long. They are either running extra length on the ground, which is a safety hazard, or there is excess hanging before the applicator connection, which can cause heating inconsistency issues. It is important to measure from the tank through the entire hose travel process, including mounting straps, before ordering. Universal Systems SE manufactures our ClearFlow™ line of heated hoses in 2 ft increments. So, if you measure 6 ft, order a 6 ft hose and if you measure 7 ft, order an 8ft hose. Make sure that you measure precisely! If need a hose longer than 24 ft, we can custom make you any length up to 50 ft.

An interesting fact about the packaging industry that most people don’t realize, is that purchasing agents become avid internet hunters when it comes to finding parts for their old equipment. There are several resources out there, the largest being eBay, for purchasing agents to find and buy parts for their old adhesive melters. The problem is, when buying from a bid platform, you never know what you are going to get. If you are looking for an old part, for a melter that is more than 20 years old, the part you find online could either be used or the wrong part. Also, with most online bid platforms, you get what you get. There are no returns or exchanges for your actual part. And in most cases, you get what you pay for.
Universal Systems SE realizes how important it is to be an online resource of purchasing agents, which is why we have invested in becoming “searchable”. In the last couple of years, we have launched a new website, added more products, and increased the number of cross-reference IDs on our website. We have added pictures, spec sheets and custom contact forms to help purchasing agents get exactly what they need. We are also working on making sure that we show up in the search results when purchasing agents Google old part numbers or manufacturers.
The benefit of buying from USSE is that all of our equipment is new, in stock and you can talk with a technician to make sure it will fit with your current equipment. Another key aspect of working with USSE is our staff of knowledgeable engineers that have been around adhesive melters and packaging line equipment for over 40 years. If you have a question about your old melter, we are most likely the only company in the industry that can answer it.
To test out the knowledge of our technicians, give us a call at (800) 848-5018. We are certain we can get your old equipment back up and running in record time.
A trend that we were seeing in 2019 in the packaging industry was repair, repurpose, repeat. No one seemed to want to spend the money on new equipment. It did not really come as much of a surprise since the political atmosphere of the United States was so polarizing. With inconsistency in government and leadership, comes inconsistency in the business world. Large CPGs were not interested in allocating budget to new equipment, but trying to repair old equipment.
What large CPGs fail to realize is that band-aiding an issue with a packaging system, only delays the inevitable. Having to invest in new equipment. This process can be a long and tedious one. Getting multiple quotes from different manufacturers and lead times. Also, needing to know availability and compatibility with your current packaging line. The new tank buying process could take months, and if your old equipment fails while in the middle of that process, your lines could be down and production at a standstill. That is a very big risk to take.
At Universal Systems SE, we offer six different hot melt tanks and application systems that could fit almost any packaging line. All of our ProBilt™ tanks are the same physical footprint as most Nordson® tanks and compatible with most Nordson® equipment, both old and new. Universal Systems SE also offers a Trade In Trade Up Program, where you can send us back your old melter, no matter who manufactured it, and we will give you a credit towards your new ProBilt™ tank.
All Universal Systems SE standard ProBilt™ systems are in stock and can ship within one business day of ordering. So, if you are ever in a bind, or your current systems goes down and is unrepairable, we can have you up and running with a brand-new system the next day. The only system that requires a lead time is the Phoenix Auto-fill System, which is usually customized per order.
Another unbeatable aspect of investing in a ProBilt™ systems is the 10-year heater warranty that Universal Systems SE offers. It is the longest warranty in the industry.

As we head into the New Year and the weather gets colder, you may be experiencing inconsistencies with the adhesives on your packaging lines. What most line operators and maintenance managers do not realize is that the location of your packaging line in the plant can play a large role in the dependability of your adhesive.
This time of year, we receive several troubleshooting calls regarding hot melt consistency, heated hose and gun temperature consistency and glue stringing. It is important to take the external environment into consideration when attempting the first step in troubleshooting some of these problems. One of the first questions to ask is: where is your packaging line located? For example, if it is at the end of the packaging process, which it most likely is, then it might be on the exterior wall of your plant. Or it might be near an external door or window. If it is on the outskirts of the plant facility, and you are located in a part of the United States that is cold in the winter, then the outside temperature could be impacting not only the viscosity of your glue, but the heating time of your glue and its adhesion ability.
Every time your line operator opens the fill door on the hot melt tank, the external air hits the existing glue and cools it off. Even if the lid on your tank is only open for a few minutes, that could impact not only the current glue in the tank reservoir, but the glue you are adding to the tank. Especially if you are adding in cold glue. If your glue pellets are colder than normal, it will take a longer amount of time to heat them. A solution to this issue would be to invest in an auto-fill hot melt application system. Universal Systems SE manufactures the ProBilt™ Phoenix Auto-Fill Application System. Not only will this system help in the winter months, it helps all year long by drastically reducing the number of times your line operator needs to add glue pellets.
Another important task would be to inspect your system setup for any cold joints. A cold joint would be any unnecessary extensions that you have added throughout the adhesive application process. Most cold joints are found on older machines that used larger sized extensions and filter housings. For example, the older gun filter assemblies had larger filter housings and longer extension joints, that are unnecessary and can inhibit the consistency of hot melt flow. The more cold joints on the system, the more inconsistent the glue will heat and stay heated throughout the entire application process.
If your main problem is glue stringing in the colder months, an easy solution would be to shorten the distance from the nozzle tip to the top of the box. Limiting the amount of time the glue has to travel in the air will help to lessen the problem of stringing, which can cause a weakened seal on the box.

There are a few brands to consider when shopping for a hot melt system for your packaging line. Universal Systems SE’s ProBilt™ product line has been around for over 40 years and has several key features that can help influence purchasing agents, as well as line operators, on why it is the best in the industry.
4 Hose / 4 Gun Standard Capability
Unlike any other hot melt tank option on the market, the ProBilt™ line of melters all come equipped with 4 hose and 4 gun capability. This is a standard option that is usually an add on from other manufacturers, like Nordson®. Nordson® has both the 2 hose/ 2 gun and 4 hose/ 4 gun melters, each differing in price. The ProBilt™ melters all come with 4 hose/ 4 gun capability at a lower price point than any Nordson®. This allows our customers versatility and the option to grow.
Easy to Program Control Board
One of the many benefits to owning a ProBilt™ system is the easy to operate, AccuScan™ Control Board. If you are plugging in a brand new tank, the board will be programmed to our factory settings. The line operator, can scan through the hose, gun and tank settings and set them to the temperatures needed. There are also a few fail safes installed in the machine. For example, if it is a cold start set up, the hoses and tank will heat first, then the guns will start to heat once the hose and tank are within 35 degrees of the set point. The reason for this is so that the gun doesn’t char, since the gun heats up faster than the hose and tank. Once temperature is reached, the “Heat On” light will blink and you are ready to use. The control board also comes equipped with alarm settings and a set back functionality, our next two key features.
Set Back Functionality
The set back functionality is one of the most important features that comes standard on all ProBilt™ tanks. Essentially, when the shift is over and you no longer need to run your packaging line, you push the set back button. This will “set back” the temperature of the tank, hoses and guns to 165 degrees. Allowing the glue already in the system to sit overnight without charring. When the morning comes, or the next shift starts, simply hit the set back button again, and all previous temperature settings will re-engage. This will decrease the start up time on the hot melt system significantly and allow your lines to be fully operational within minutes.
Another key feature to the AccuScan™ Control Board are the alarm options it provides. The first alarm option allows for the panel to tie to an alarm light in your facility. In case anything happens that stops the system from running effectively, an alarm light can go off, alerting the line operator immediately. Another feature is the ability to tie it to the packaging line itself, called PMI or Parent Machine Interface. Parent Machine Interface will signal the packaging line when the glue is at full temperature thus preventing the line to start up until it receives the signal.

Over the years, large CPG companies moved away from manufacturing and packaging their products in the USA. There are is one obvious reason for that, cutting costs. The cost of materials and the cost of labor are both cheaper overseas. But cheaper isn’t always better. Yes, it increases overall profitability, which is essential for a company’s success, but cutting costs can also equate to lower quality products, poor customer service and lack of reliability.
Well, times are changing! With impending tariffs worldwide, it might not be the best option for you to work with a company that manufactures overseas.
Here at Universal Systems SE, we are proud to stamp “Made in the USA” on all of our components. Whether you are buying a nozzle or ProBilt™ tank, you can rest assured that they were 100% made here in the USA. We source all of our raw materials from US companies, and try to keep them “in the family” of small business owners. Not only do we believe in keeping everything home grown, we support small businesses, the true bread and butter of this great nation.
There is also the advantage of immediate customer service, when dealing with a US company like Universal Systems SE. We are here when you need us, to troubleshoot any questions or if you need products overnight. Since our manufacturing facility is in Delray Beach, FL, we operate on EST, so even companies on the west coast can catch us in the morning or early afternoon.
For more information on the products that we manufacture here in the USA, please email email@example.com or call us at (800) 848-5018.
The most common type of hot melt system used on packaging lines is a manual fill system. With manual fill systems, there are several roadblocks that can occur with safety and productivity that many companies are experiencing. Universal Systems SE took those concerns into consideration when designing our ProBilt™ Phoenix auto-fill system.
It is first important to understand how a hot melt system works. Hot melt adhesive application systems house a Teflon® coated interior tank, where the glue pellets are added and melted. The glue is then pumped out, travelling through a heated hose, into an applicator gun, through a module and nozzle, finally landing the glue at its final destination.
Universal Systems SE has ProBilt™ tanks that range from an 8 lb (4L) capacity, up to a 20 lb (10 L) capacity. Depending on how many hours per day the packaging line is operated, and the size of the glue tank needed, line operators are in charge of making sure that there are always glue pellets in the melter. Running low on glue inside the melter tank can cause a plethora of issues with the system. One of the most common issues is running the pump dry. If a line operator lets the tank run dry and the pump “shotguns”, the pump or shifter can fail. Honestly, that is the most common cause for pump rebuilds that we see in our shop. The easy solution to this is making sure that the tank is always full with pellets.
However, consistent tank filling can increase the risk of other potential issues. The first, is that it increases the risk to employees. Since the tank runs anywhere between 200 – 400 degrees, it is HOT. If a line operator is in a rush or makes one careless move, they can easily be burned by the pot. Another issue is that when you open the tank lid to refill with pellets, cold air flows into the tank and cools down the internal temperature. If the glue is continuously getting hot and cold, it could negatively impact its bonding ability.
These potential issues prompted Universal Systems to develop and release our ProBilt™ Phoenix auto-fill system in 2018. Unlike with manual filling, the automatic filling process does not require the line operator to fill glue pellets directly into the hot tank. Operators fill the free-standing container, which is separate from the tank. The glue pellets are then deposited into the internal pot via the vacuum and wand system when the internal tank glue level is low. The Phoenix is available in two tank capacities, the 15 lb and 20 lb units. Each glue container has maximum and minimum fill lines so that line operators know how much or how little to fill the pellets. Since the containers can hold much more glue than a standard heated pot, line operators no longer need to worry about checking the melters as often as with a manual system. This will also ensure that line operators will not get burned and that the glue inside the pot will stay consistently heated, creating maximum bonding ability.
