The trend in packaging for many CPGs has been to move away from in-house packaging solutions and more towards co-packers and contract packagers. Rather than dedicating complete in-house lines, CPGs and processors can be more flexible with their budgets by putting the responsibility of capital investments for machinery in the hands of the contract packagers. In addition, the CPGs no longer have to worry about hiring line operators for the packaging machines. In the last few years, it has become clear that hiring, retaining and training employees is a challenge for every company. CPGs are finding that if they move the responsibility of packaging to contract companies, they no longer have to deal with that potential issue.
The move to contract packaging is not a bad thing for glue equipment OEMs, like Universal Systems SE. We enjoy working with contract packagers because they are equipped with the skills and knowledge to focus on packaging lines and, in most cases, know what they want and need from a hot glue machine, more than a CPG will.
Below is a list of requirements we are hearing about from Contract Packagers for their packaging equipment, and an explanation as to why Universal Systems ProBilt systems will work best to fulfill these needs.

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.
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.
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.
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.
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.

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!
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.
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.
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.
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.
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.

There are two types of filters used in hot melt systems. The first, and most popular are the inline filters that go between the hose and the gun. These filters help reduce the transfer of char from the hose into the gun applicator. However, there is another type of filter that is just as important, and commonly overlooked. Your system’s tank filter.
Unlike an inline gun filter, that will come with either a straight, 45 degree or 90 degree filter body that houses a small inline mesh filter and mounts to your applicator gun, the tank filter is simply a long round cylinder that fits inside your tank itself. The tank filter’s job is to filter the glue out of the tank into the hose, reducing any burnt or charred old adhesive in the tank from clogging up your hoses.
Universal Systems SE recommends that you check and replace your tank filter every 500 hours. In order to check the filter, you can locate it in the lower right-hand side of your system tank. You may not need to replace the entire filter, so first check the screen. Below is an example of what the entire tank filter assembly will look like, compared to only the screen.

One of the most dangerous, yet inevitable, occurrences running hot melt systems in your packaging lines is char. Universal Systems SE has updated technology running in our ClearFlow™ hoses that reduces char, however the main char that runs through the hoses comes from the tank itself. Once your tank is infested with char, no matter how efficiently your hoses and guns run, there is always the potential to transfer this char onto your packages. You also run the risk of char clogging your nozzles and modules, which can back up through your guns and kill your pumps. Our Universal Systems SE technicians have seen it all. That is why we have created a list of preventative tips that each line operator should follow to effectively reduce char and keep your ProBilt® system running at top capacity.
Universal Systems Se recommends a complete hot melt system cleaning at least twice a year using our Purge Plus™ system cleaner.
Hot melt adhesive should always be stored in a strong container such as a heavy-duty plastic waste container. Do not set boxes or open bags of adhesive on the floor or on the top of the container. The container should be labeled “Adhesive Only” and include your adhesive part number.
Low Quality Adhesive
With hot melt adhesives, higher price usually means higher quality, the opposite is also true. Adhesive manufacturing is a highly un-regulated industry and many companies use low cost waxes and fillers in their products to reduce cost. These products tend to burn quickly. Due to the fillers and heavy waxes, low cost adhesives can greatly reduce your adhesive mileage whereas high quality adhesives are lighter and have a lower specific gravity. The bottom line is a higher dollar per pound does not necessarily translate to higher packaging costs. We also recommend that you do not mix old adhesives with new brand adhesives. Please read our past blog to help you understand why.
Hot melt systems are not cheap, so most of the ones in operation today have been on their packaging lines for 10 – 20 years, whether they are running properly or not. That means that most likely, these older machines have char built up in their tanks. It may be time to evaluate the performance and efficiency of your aging equipment and trade up to a new ProBilt®.

First and foremost, your melter adhesive filter should be flushed once a day. Cleaning your melter filter can be dangerous so always remember to wear safety glasses and heavy duty gloves. This will help to prevent any injuries that might be caused by splashing hot melt adhesive during the flushing process.
The first thing you must do is heat your system to its operating temperature. This is very important to prevent damage to the filter screen. Next, you will need to reduce your pump air pressure to zero at the air regulator. Then, you must relieve the system pressure by triggering any and all guns. This will now relieve trapped hydraulic pressure. After all system pressure is released, you can open the manifold drain valve. Using a screwdriver, open the valve over an open container. You then want to slightly increase pump pressure until a steady flow of adhesive comes from the drain. Continue to allow material to flow until it appears clean and free from any foreign matter. Once the adhesive appears to be clear, shut off the air pressure to the pump and close the manifold drain valve. You now have successfully cleaned your melter filter.
The importance of a clean filter when operating your melter system is imperative to running a high-quality machine. Many people wonder if they should clean their filters or if they should buy new. The easiest way to tell if your filter should be replaced is if you have used it for longer than 200 hours. Every high-quality filter, even when cleaned daily, will only last up to 200 hours of operating time.
If you do need to replace your filter please follow the below steps.
- Heat the system to operating temperature.
- Reduce your pump air pressure to zero and trigger all guns to relieve trapped hydraulic pressure.
- Loosen the filter with a socket type wrench.
- Wearing Kevlar gloves, carefully pull the filter assembly out of the manifold.
- Remove the screw in the back of the filter assembly and discard the filter screen.
- Replace the filter screen and reinstall screw.
- Inspect o-rings for damage and replace if necessary.
- Slide the filter assembly back into the manifold and tighten until it seats.
Make sure that you purge the manifold by opening the drain valve and increasing the pump air pressure slightly until a steady flow of hot melt is released from the drain. Close the drain valve and your machine is ready to operate with your new filter.
