Have Spares on the Shelf

As we navigate through this pandemic of 2020, we are noticing more and more packaging partners not getting the budgets to do much of anything with their packaging equipment. Even with the increase in demand for consumer goods like toilet paper and hand sanitizer, many packaging lines have limited shifts due to social distancing guidelines, making sure to keep their employees safe and healthy. As the country starts to slowly re-open, so will packaging lines…and nothing good comes out of a glue pot that has been sitting idle for over 6 weeks. That is why our number one recommendation to all facilities, other than to clean the pots before restart, is to make sure to keep spares on the shelf!

The most common hot melt equipment that should be replaced upon restarting a line are tank filters and in-line filters. Those filters will help with any char that is created once the line starts back up and running again. Another recommendation is to clean the pot with Purge Plus. It is so important to get the old glue out of the pot, before putting the new pellets in. It is also smart to keep spare modules and nozzles on the shelf. Those items can easily clog with char. Luckily, Universal Systems keeps over 10,000 items in stock and on the shelf for easy shipment whenever you need them.

If you are getting ready to restart a line and have any questions on best practices or the steps you should take to ensure a smooth manufacturing process, please call to speak with a technical rep at (561) 272-5442 or email sales@ussefl.com.

Heated Hoses Can Transport More Than Adhesives

While adhesive application is Universal Systems’ main focus, several of our customers utilize our heated hoses for more than just adhesive. Our standard line of ClearFlow™ heated hoses can heat up to 450 degrees, run at 240v and have a maximum operating pressure of 1500 psi. We also manufacture custom transfer hoses which run at 120v and typically transfer material that heats at a lower temperature. For example, cosmetics, wax and chocolate or candy.

There are several CPGs out there that utilize heated hoses for more than just packaging. Our hoses can transfer any of the following materials:

  • Cosmetics
  • Chocolate
  • Candy
  • Wax
  • Air
  • Vape Liquid
  • Polyethylene
  • Paint
  • Tar
  • Food Oils
  • Water
  • Ink

One of our clients is a great example of how versatile our hoses are. They are a cosmetic packaging company that recently utilized our services to bottle a hair gel product, specifically made for curly hair. Their conveyer worked methodically to fill the bottle with water, then moved to fill with the hair gel formula. The combination of water and product created a foam, which needed to be eliminated quickly in order to keep the process moving. A spurt of hot air down into the top of the bottle is just what was needed before capping. Our heated hoses transferred, not only the water and hair gel product, but also the hot air needed to eliminate the foam.

We also have several clients who utilize our entire hot melt system to heat wax pellets, transfer them through the heated hoses and fill plastic molds. After the wax is transferred into the form mold, it is then moved to a cooling tray to harden and get ready to package. A separate Universal Systems ProBilt™ system is then used to seal the product box and ultimately the case.

So, if you are interested in utilizing a ProBilt™ system or ClearFlow™ hose for more than just adhesives and final packaging, give us a call and we can help! Please call (800) 848-5018 or email sales@ussefl.com for more information.

Correct Hose Length

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.

To speak with a USSE representative about our ClearFlow™ hoses or to consult with a technician about the hose length you need, please call (800) 848-5018 or email sales@ussefl.com.

Hunting Down Old Adhesive Melter Parts

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.

How Winter Weather Impacts Your Packaging Line

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.

For any further information on the ProBilt™ Phoenix Auto-Fill Application System, or to speak to a technician about any troubleshooting of your adhesive application system, please call Universal Systems SE at (800) 848-5018 or email sales@ussefl.com.

The Right Melter for Your Packaging Line

The scenario is usually the same, a packaging line melter goes out in the middle of the busiest time of year. Most commonly, maintenance directors and buyers simply replace the current OEM melter with the latest model. That is not always necessary. Universal Systems SE ProBilt™ melters have the same footprint as most all Nordson® systems and can easily fit into where the original tank is positioned. Just because your current packaging line has a Nordson® melter does not mean you have to replace it with another expensive Nordson®. Plus, all of our ProBilt™ melters are in stock and can ship same day!

There are several key points to take into consideration when choosing a hot melt system for your packaging line. The most important are: Melt Rate, Durability, & Cost-Effectiveness.

Melt Rate

The melt rate is the rate at which the tank will melt the adhesive you put into the reservoir. This is where the tank capacity comes into play. Before moving forward with any hot melt adhesive system, first you need to understand how many pounds you need to melt per hour. The melt rate is dependent on how many hoses and gun applicators you are running and how many boxes are sealed per minute on your packaging line. The most common tank capacity is the 20 lb. (10 Liter) ProBilt™ 20, with a melt rate of 23 lbs. per hour. If you are only running one line with one hose and gun applicator, then you may only need the 15 lb. (7 Liter) ProBilt™ 15 which melts 18 lbs. per hour.

Durability

Depending on how many shifts you are running, you need a melter that will work consistently and effectively. All ProBilt™ melters come with a 10-year heater warranty, which is the highest in the industry. In addition, all melters come standard with 4 hose / 4 gun capability and a set-back functionality that allows for easy start up and shut down. ProBilt™ melters are constructed out of 316 stainless steel, not only for its sleek look that will seamlessly blend with your packaging line, but also for its durability and sustainability through the tough elements a packaging line ensures.

Cost-Effectiveness

The economy has become a roller-coaster in the last year. With that, large CPGs are cutting back not only in personnel but in spending budgets for packaging. These tighter budgets won’t always allow for a buyer to simply purchase the latest Nordson® melter. Here at Universal Systems SE, we have seen more and more companies trying to repair older melters and plug any current issues with band-aids to stretch their fixed budgets as far as they can. Since we manufacture parts that are compatible with old Nordson® tanks, we have been able to help a lot of companies cost effectively navigate the times. In addition to our parts business, all of our ProBilt™ series melters are cost effective replacements for any Nordson®.

CPGs Wrestle with Workforce

If you follow the packaging industry, whether through news articles, industry periodicals or first hand through direct buyers at CPG companies, one of the largest drivers in packaging is the stress on workforce demands. This can include how difficult it is to find reliable workers that are dedicated to the success of the company. It can also be in the aspect that most of the line operators working the packaging line equipment are not trained properly on that piece of equipment and all of its capabilities.

As the packaging industry tries to modernize technology, not all of their workforce can keep up. As a hot melt equipment manufacturer, one of our core competencies is our knowledgeable technical support. If you have any Universal Systems SE equipment or ProBilt™ machines on your packaging lines, you can rest assured that you will get speedy, knowledgeable sales and technical support. However, in many instances, line operators do not have that type of experience or knowledge base. That can lead to “on the fly” fixes, which usually equates to weakened product and voided warranties. At Universal Systems SE we understand that knowledge is power, and we want to make line operators jobs easier, not harder. With that in mind, we have kept all of the ProBilt™ hot melt application systems uniform and easy to operate. We also try to make our clients smarter when they call with issues, asking questions to help them learn or giving them some simple troubleshooting tips to follow for the future.

In addition to being able to help line operators with questions and knowledge, we also make sure to include in every shipment all of the pertinent manuals and information guidelines needed. For example, if your company is ordering ClearFlow™ heated hoses (Universal Systems SE’s proprietary line of heated hot melt hoses), each shipment will include installation and care instructions. The same goes for our ProBilt™ applicator guns. With the purchase of any ProBilt™ application gun, we include a list of maintenance recommendations on the gun, modules and nozzles.

So, as CPGs continue to have concerns with their workforce, we here at Universal Systems SE  we will continue to do everything in our power to ensure that we keep them knowledgeable on our equipment.

To learn more about our ClearFlow™ hoses or any other ProBilt™ products, please reach out to sales@ussefl.com or call (561) 272-5442.

RTD Sensors

RTD Sensors (resistance temperature detectors) are used in hot melt packaging systems because of their precision in sensing and proportioning temperature. They consistently maintain a temperature control stability of +/- 1-degree Fahrenheit. With the ever-increasing price of adhesive, it is important that RTD sensors are used in all of Universal Systems’ hot melt hoses and glue applicators for steady adhesive application. When combined with USSE’s patented AccuScan™ solid-state control system, RTD sensors provide precise bead uniformity for all of our ProBilt™ applicators.

Since RTD sensors are so key to the adhesive application process, it is important to check them first whenever you notice glue inconsistencies. If you see that your glue bead is not sticking properly or getting clogged, it could be caused by inconsistent glue temperature. There are several causes of inconsistent glue temperature. For example, if your tank operators are opening the cover to add glue, that will cause a temperature change. RTDs control that process, by notifying the heater to turn on and run longer when those situations occur. If your RTD is weak, then the heater will not be able to maintain steady temperature. It is the easiest, most overlooked and one of the least expensive components in your application process, but is worth it’s weight in glue!

When it comes to understanding the components that make up your adhesive application system, we believe that knowledge is power. So, if you have any questions, or think that you may be having issues with your RTD sensor, do not hesitate to call Universal Systems at (800) 848-5018 to speak with one of our technicians. We can walk your line operator through testing RTD sensors and how to switch them out correctly and safely.

Managing Your Glue Usage in Packaging

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.

Nozzle Diameter

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.

Evaluate Set-up

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.

Line Operators: The First Line of Defense

Understanding hot melt tank systems is no simple task. It usually takes years of experience to learn how to effectively manage adhesive systems and keep your packaging line running efficiently and effectively. Universal Systems SE understands that new line operators come into work and might need help learning which items to replace and how to replace them the correct way. That is why we offer technical support to all of our ProBilt™ customers!

There are several maintenance tasks that we recommend be completed on a regular basis to keep your adhesive system free of char and debris, which is the number one culprit in bringing down a line. Below is an easy maintenance checklist that each line operator should have in hand.

We recommend that you print this checklist out and give it to every shift that operates the packaging line. Keep in mind that changing out items such as gun heads, modules, filters and pumps all require you to clear the old lines and remove the air pressure before re-installation. Releasing the air pressure and removing all old adhesive will ensure that all seals stay intact and reduces the char transferred from the old to the new parts.

If you need help changing out parts or have questions about which items need to be changed regularly, please call (561) 272-5442 or email sales@ussefl.com.
