The Importance of Air Quality in Packaging

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.

The Importance of Graphite Seals & PTFE in Hot Melt Equipment

Graphite seals and PTFE are used in all of Universal Systems SE’s pumps and modules to increase the longevity and life of those products. But why? In order to understand how we can boast about the quality of our products, it is first important to understand the quality and reasoning behind using certain key components.

Graphite seals are used in both the pumps and modules to create a smooth seal for the piston to move seamlessly through. Below are a few bullet points that explain why this particular component is so important.

  • Excellent heat resistance – up to 500°F – most all hot melt adhesive systems will heat up to 450°F, so even if a packaging line runs at the highest temperature allowed by the system, the graphite seals will remain unscathed.
  • It has a medium to high pressure rating – the maximum operating pressure on any pump should not exceed 35 – 45 psi. The most common operating pressure is 20 – 25 psi. These seals are rated perfectly for this type of application.
  • Excellent abrasion resistance – some packaging lines are not run with the cleanest adhesives, so utilizing graphite seals allows for any adverse environmental condition.
  • Very resistant to chemicals – this allows the end user the ability to not only use multiple types of adhesives, but cleaners as well.
  • Excellent extrusion resistance in severe conditions.

When Consumers Can’t Open their Boxes

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.

New Year, New Melter

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.

For more information on Universal Systems SE’s line of ProBilt™ equipment or how you can get a new melter in 2020, call us at (800) 848-5018 or email sales@ussefl.com.

Utilizing Key Features of the ProBilt™ Hot Glue System

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.

Alarm Options

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.

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.

Zero Cavity Modules and What They Are Used For

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. If you would like to learn more about zero cavity modules or get a price quote, please reach out to sales@ussefl.com or call (561) 272-5442.

How to Keep Old Melters Operable

Do you have an old series 2300 or 3000 melter that you are still using but need to find parts for? If you do, your packaging line is running a melter that is 15 – 20 years old. That means that your line operators are maintaining your packaging lines well and spending money in the right areas to keep efficiency and durability a priority. With that said, not everything will last forever. While you can probably keep the control panels of the 2300 or 3000 melter, some of the internal and exterior parts may need to be replaced. The reality is that Nordson® no longer supports these tanks. However, Universal Systems SE does. Universal Systems SE manufactures pumps, filters, hoses, guns, modules and nozzles that are compatible with your old melters.

Pneumatic Pumps

The first thing to go on your old melter, will most likely be your pump. Once that stops working, it will become very clear that your OEM no longer manufactures replacements for that part. So now you have to decide between purchasing a new melter from them for $15,000+, or trying to replace your pump. Universal Systems SE manufactures new series 2300 and 3000 pumps for a fraction of the price of a new Nordson® melter. Check out our full line of pneumatic pumps.

Actuator

If you have experience with rebuilding pumps, Universal Systems also manufactures the pump shifter and fork for the ProBilt™ series 2300 and 3000 pumps. This is another item you will not be able to find with the OEM because it has been discontinued.

Tank Filters

Since your series 2300 or 3000 melters have been operating on the line for so many years, your line operators probably change out the tank filters frequently. As the years have gone by, you may find it more difficult to find reasonably priced, or readily available tank filters. Universal Systems manufactures the tank filter assemblies, filter cores and filter screens to fit your series 2300 and 3000 melters.

Same Footprint

If you have gone through all of the steps to fix the problem with your old melter and find out that it is the control panel, which has been discontinued, Universal Systems SE has a solution for that as well. Our ProBilt™ melters have the same footprint and dimensions as your current series 2300 or 3000 melter. That means that your NEW ProBilt™ melter, that comes with a 10-year heater warranty, will fit right in where your old melter comes out.

For more information or to contact a technician that can help you troubleshoot issues with your old melter, call (561) 272-5442 or email sales@ussefl.com.

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.

For more information or tips on how to increase your packaging line efficiency and lower your costs, call a Universal Systems representative at (561) 272-5442 or email us at sales@ussefl.com.
