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!
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.

The packaging industry is unique, and can be a tough industry to buy for. It is important for purchasing agents to understand how their hot melt systems operate in order to ensure they are buying the correct parts. Hot melt manufacturers are full of highly educated engineers that have honed their skills over time. At Universal Systems SE, we combine our experience of over 40+ years to keep our products ever evolving and ensure we are still at the top of the industry, while offering our expertise to help our customer purchasing agents make the right choices.
Keeping up to date on the latest trends is not only important for us as manufacturers, but it is also important for buyers. Below are 5 important facts that every hot melt equipment buyer needs to keep in mind before making a purchase.
- Durability – at USSE, we stand behind the durability and craftsmanship of our products. That means that we offer a solid warranty, longer than all of our competitors.
- In Stock Products & Compatibility – whenever you call to inquire about the pricing on a melter or replacement part, make sure you remember to ask if the part is in stock. There are several choices that you have when ordering both main and replacement parts. Most all companies make their parts compatible with industry standards.
- Tank Capacity – make sure your melter’s tank capacity matches your packaging line output. This will ensure that you have the correct tank needed for the job.
- Match Your Adhesive and Your Pump – the pump needs to match the viscosity of your chosen hot melt adhesive. This is key to making sure that you are ordering the correct style pump to dispense the adhesive on your packaging materials.
- Usability – the best melters will be easy to operate, easy to change out replacement parts, and easy to clean and maintain. They will also come with smart features like USSE offers on all of our ProBilt adhesive melters.
At Universal Systems SE we are dedicated to the education of both our customers and the next generation of hot melt engineers.
