The Importance of Product Support

Universal Systems SE has been manufacturing hot melt equipment since 1981. Starting with hoses and nozzles, then moving into applicators, pumps and tanks. Our first ProBilt tank was launched in 1990. Since then, our melter has only had a couple of generational upgrades. We believe that this is what sets us apart from other hot melt equipment manufacturers in the industry today. We have never believed upgrading our equipment or technology so much that it makes our old tanks in operation obsolete. We have added features and improved upon what we initially launched in 1990, but we have not let technology negatively impact the operational ease of our machines.

USSE believes in the importance of long-term product support and cross compatibility. There are hot melt system manufacturer’s in the industry, like Nordson®, who have discontinued not only production but also product support of their old melters. Both the 2300 series and 3000 series melters, while discontinued by Nordson®, are still in operation in hundreds of packaging facilities across America. Unlike Nordson®, Universal Systems still supports those old melters because we appreciate the fact that many of these melters, similar to the ProBilt melters, continue to run even 20+ years after initial operation. We are one of the only manufacturers in existence to still make and service 2300 & 3000 series pumps.

We also believe in product uniformity across all of our melters. That is why when we designed our melters, we made sure that all of Universal Systems’ ProBilt machines run the same control boards, pumps and tank filters. In most cases, facilities run several ProBilt melters, but only need to stock 1 or 2 of each spare part. That uniformity creates a streamlined and more simplistic inventory process.

As we move deeper into 2021 and our new normal continues to change, think about how the importance of long-term product support and a streamlined inventory process can help keep your packaging lines up and running.

Packaging in the Pharmaceutical Industry

It’s been a wild ride over the last year, but the pandemic has brought on several advances in the pharmaceutical industry. Hot melt application in the pharmaceutical industry has always been important, but now more than ever. As the US pushes forward with millions of vaccines, each medication needs to be precisely packaged to make sure that it arrives safely to its destination.

Universal Systems manufactures ProBilt Zero Cavity Modules to apply a thin line of hot melt along medication boxes. Zero cavity modules have a very specific look, with a matched needle and nozzle assembly which eliminates minute material pockets that can cause nozzle clogging or dripping. They also come with an E-Z Micro Adjust option to that allows the operator to “dial in” on an exact adhesive extrusion and precise bead placement. 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 the precision requirements, 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 nozzle 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.

Safety in Switching Out Glue Equipment

The best way to keep your packaging line up and running as efficiently as possible is to do preventative maintenance. Here at Universal Systems SE, we have advocated for regular packaging line maintenance, including all of your glue melter equipment and components. However, it is not only important to know when to do maintenance, it is also important to know how to do that maintenance. There are more mistakes made in the switching out of glue equipment and components than you may think. Whether you are changing out a filter or switching a pump, there are steps to take in order to ensure a smooth transition, with the least amount of downtime. Here are a few tips on switching some of our ProBilt hot melt equipment products.

Tank Filters

First and foremost, it is important to know the model of your tank. Even though that sounds like standard knowledge, there are many tanks that look similar but have different tank capacities, pump types and filters. Once you know the tank model, you can look up if you need to replace the entire tank filter or if you can replace just the screen. On USSE’s ProBilt tanks, for example, you have the option to change only the tank screen. This allows you to save some money long term, while still maintaining your tank. It is recommended that you make the change while the tank is in setback and to wear Kevlar gloves so that you don’t burn yourself. The tank filter is located on the side of the tank. It can be removed with a flat head screw driver. Once the complete filter assembly is removed, there is a long screw that secures the screen to the assembly. Simply remove that screw, switch the screen, and replace the filter assembly. If you are changing out the tank screen, make sure that you do not damage the filter bung or o-rings when making the switch. Also, be careful, the glue inside the filter is HOT.

In-line Gun Filters

These are the easiest of filters on your glue line to change out. In most cases, the filters can be reordered in packs of 5. Locate where the filter is on the filter assembly body and use a wrench to loosen and remove. Kevlar gloves should be worn, as the outside of the filter will be hot and there will be glue on the filter you are removing. Simply put the new filter in place and tighten.

Modules

Usually modules are switched out because they are dripping or leaking. This is typically caused by either char or end of life of seat and piston. Switching out a module is fairly simple. Before taking off the old module and replacing with the new, make sure that the system is not running. Each replacement module comes with 2 o-rings and 2 screws. Place the o-rings on the back of the module and secure it on the gun applicator with the new screws.

If you are running an H200, zero cavity or reduced cavity module, there are rebuild kits available.

Pumps

Switching out a glue pump is the least common practice on a packaging line. However, this is also simpler than you would think. Most technicians think that in order to change out a pump, you need to turn the tank off and let the glue cool. That is not always the case. If you are running a ProBilt tank and have an experience technician, he can switch out the pump while the system is still on. First, make sure you are wearing Kevlar gloves because the system will be hot. Turn off the air running to the system, this will limit any injuries. Remove the 3 bolts holding in the pump, use needle-nose pliers and do this carefully. Put the old pump on a large piece of cardboard where the glue can drain, cool and harden. Carefully put the new pump in, secure it with the 3 bolts and turn back on the air.

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.

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.

Modules: The Glue That Holds Your Adhesive Melter Together

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.

The Difference Between a Glue Gun Head and Module

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:

  1. 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.
  2. 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.
  3. 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.

If you have any questions on which items you may need, please reach out to a sales representative by either calling (561) 272-5442 or emailing sales@ussefl.com. We manufacture all products in the United States and are here to offer the best price possible to get your packaging line up and running as quickly as possible.
