Best Practices to Ease Supply Chain Burdens

It is no secret that everyone is experience supply chain issues this year. While there may be no end in sight, Universal Systems can only try and help ease the burdens on our end users. Below are a few of the best practices that we have implemented that we can recommend for our customers.

Keep an Open Line of Communication

With several of our competitors experiencing supply chain issues due to their overseas manufacturing and shipping issues in the current cultural climate, Universal Systems, being a USA manufacturer has received a lot of new business from large end users of hot melt equipment who would normally be buying from the big-name brand manufacturers. With the new influx of business, we have been open and honest with customers as to what we stock and what we make custom. If a new customer who is used to buying from Nordson calls and asks us lead time on standard stock items, we are happy to communicate that we can ship same day. However, if they have a custom gun or hose, we are honest regarding lead time and ship dates, normally 3-5 business days.

Plan Ahead

It is so important for companies to try and plan ahead with their inventory. While we realize this may be hard for many buyers due to lack of budget or their inability to get “out of the weeds” from being so far behind during Covid lockdowns, it is the only way to ensure there is no downtime on your packaging lines. Universal Systems offers all of our customers a preventative maintenance schedule and inventory recommendation list, so that you know what to keep on the shelf based on the equipment you are running.

Try New Products

Many of us get stuck in our ways and don’t realize there are other options out there that might improve our operations or way of doing business. Now that some large brand name companies, who have spent years manufacturing overseas, are feeling the crunch of no inventory due to low supply chain, many packagers should see this as an opportunity to work with Universal Systems. We have been manufacturing hot melt equipment in the USA for over 40 years and are well versed in packaging line needs and set ups. We manufacture most of the same products as our largest competitors and stock over 10,000 items at all times.

Think Outside the Box

With over 40 years of experience in packaging equipment, Universal Systems’ technicians are most skilled in thinking outside of the box. Whether it is troubleshooting an issue with an old machine that has been around since the dawn of day, or setting up a new line configuration, sometimes the most common answers don’t always work. We urge our customers to keep an open mind and work with us to figure out the best solutions to your packaging needs.

Cold Weather Impacts to Your Hot Glue Melter

As we move into the holiday season, we also experience a change in the weather. In most places in the US, the winter months mean that the climate inside most packaging plants change. With that, line operators need to take that temperature change into consideration when working with hot glue machines on their packaging lines.

Hot melt consistency, heated hose and gun temperature consistency and glue stringing are all potential problems that maintenance managers can deal with during the winter months. One of the most important things to look at is where your packaging line is located within your facility. Most melters are located at the end of the line, which leaves them close to an exterior wall, door or window. The cold temperature outside 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. If your glue pellets are colder than normal, it will take a longer amount of time to heat them.

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 use larger sized extensions and filter housings. 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.

The Importance of IN STOCK

Over the last two years, as both manufacturers and consumers, we have learned a lot about the importance of having our most vital items in stock. As we head into the end of 2021 and move into 2022, we have to believe that getting products for both our business and personal lives is going to get increasingly difficult. As large US CPGs have relied more and more on packaging machinery made in China, like Nordson®, they are finding it increasingly difficult to get products. Large corporations have been incentivized for years to move their manufacturing facilities overseas, not only because labor is cheaper, but raw material is cheaper and more readily available. With that, however, the cost of their products has increased due to tariffs and greed, and they are now unable to ship to the US, putting some large CPG facilities in a bad situation.

Here at Universal Systems, we have prided ourselves on being Made in the USA and stocking thousands of items. We still do and will remain sourcing all of our raw material within the USA, as well as keep our most popular products built and on the shelf for our valued customers that need them in order to keep their production and packaging lines up and running. If there are any CPG companies out there that are having issues getting Nordson® products, please reach out to us. We will quote pricing and lead time within 24 hours.

The importance of “in stock” has never been more valuable. We realize that and are dedicated to continue to invest in stocking products so that our customers can get their most vital items in a timely and cost-effective manner.

How to Choose the Best Applicator for your Packaging Line

Oftentimes, a packaging line comes with standard, one module applicator guns. While that is the most common applicator on the market, there are several other application options available.

When figuring out your packaging line configuration, it may become apparent that a standard one module applicator will not work for you. It really depends on what you are closing up with hot melt. Are you running a case sealer? What size and style boxes are you sealing? How many edges do you need to hit with the glue and how do they fold together in the line?  All of these questions need to be addressed before purchasing an applicator.

To help out, below is a list of some other common case sealer applicators. All of these items are in stock and ready to ship!

Low Profile

Low profile guns are one of the most commonly used guns on cartoners. Here at Universal Systems SE, we manufacture two module and four module versions to allow for easy glue distribution on small to large box sizes. Their name comes from their unique gun body design which is angled on each side. The angled design sides allow for the box flaps to flawlessly close while the gun is applying the adhesive on to the boxes.

Multi-Module Applicators

If you are running a high-speed line creating cartons that have multiple folds, such as a Douglas case erector, you may want to consider installing multiple module applicators. Universal Systems SE manufacture 2 module, 3 module, 4 module and 5 module applicators. There are various lengths between centers for each model. We recommend that you review all gun specs on our website.

 

For any other questions you may have regarding purchasing a new gun for your application, please give us a call at (561) 272-5442. We are happy to help create the best and most efficient hot melt application system possible.

How to Effectively Clean Your Melter

Keeping your hot melt adhesive system clean may not be on the top of your priority list. However, take a look at your melter now, it is probably bronzed and blackened with old melted glue and char in the glue reservoir. That is what travels through your application system and onto your boxes. That is also what is potentially causing clogging issues and why you are replacing so many nozzles. Even though your melter looks like this now, it is possible to clean it and positively impact the longevity of your system. We recommend that you clean your system at least once every quarter. If you are running 24-hour shifts, 7 days a week, then you might want to schedule cleaning once a month.

Universal Systems SE sells a product called Purge Plus™ that, when used properly, will clean almost any melter. The directions for use are simple:

  • Drain all hot melt from tank reservoir
  • Fill reservoir with Purge Plus™
  • Heat Purge Plus to 350°F – 375°F for approximately 45 minutes
  • Open tank drain valve and remove tank filter assembly
  • Slowly start pump and run Purge Plus™ through the tank manifold and into a meal container until reservoir is empty
  • Stop pump, replace filter assembly and close drain valve
  • Carefully wipe any remaining contaminants from tank reservoir
  • Add new hot melt and recirculate through system
  • Drain one cup from each hose

In addition to cleaning the tank reservoir and heated hot melt hoses, if you are running a ProBilt™ series melter, the exterior is manufactured out of 316 grade stainless steel. So, any stainless steel cleaner will shine the exterior of the tank.

For any additional questions about Purge Plus or how to properly clean your tank and hoses, please call a Universal Systems service technician at (561) 272-5442 or email tech@ussefl.com.

When to Replace a Module

One of the most commonly replaced items on any hot melt packaging line is the module. Typically confused with an applicator gun head, the module attaches to the front of the applicator gun and dispenses the glue through the nozzle and onto the applicable surface. If you are experiencing clogging issues with your hot melt line or dripping from the tip of the nozzle, most likely the module has reached it’s end of life and needs to be replaced.

Replacing a module is fairly simple. First make sure the air is disconnected from the applicator. Always wear Kevlar gloves and eye protection when replacing any parts on your active hot melt system. The parts get hot and extending downtime might not be an option, so operator safety is very important. Then, remove the front two screws from the module and pull the module off the surface of the gun manifold. Make sure that you use the new o-rings and screws that come in your new module replacement kit. This will ensure that the new seal is tight and will not leak once operations restart. Also, make sure you are replacing the existing module with the correct replacement module. Below is a list of module options:

Finally, we also recommend to put a new nozzle on every new module. This will ensure that no clogging will occur. If you have a zero cavity or ProBead module, then the nozzle will already be attached.

If you need any more information about modules for your packaging line, please email sales@ussefl.com or call (561) 272-5442.

How to Change Out a Melter Pump

There are several reasons why a melter’s pump might stop working. The most common reasons are clogging of the ball and seat from foreign matter such as carton dust, and the actuator clogging due to dirty or oily air. No matter what the reason, if your pump stops pumping it needs to be replaced. Obviously, it much more cost effective to change out a pump then to replace the entire unit. However, it is not always easy to switch out a pump, especially if you are new to the line. Below are a few tips to help ease you through the process.

  • Make sure the circuit breaker on the front of the unit is set to OFF once the applicator has reached normal application temperature.
  • Shut OFF the input air to the pump.
  • Set the pump regulator to zero and trigger all guns to relieve system pressure.
  • When removing the old pump, rotate it slightly to break the suction and then pull it straight up and out.
  • When installing the new pump, make sure to torque the screws 15-16 ft-lbs.
  • Connect the pump electrical plug to tank receptacle and turn tank back on.
  • Once the tank board reads that the tank has reached set temperature, wait 15 minutes. This will allow the glue around the pump hydraulics to get to temperature.
  • After waiting 15 minutes, reinstall the air regulator and connect the airline and activate air.

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.

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.
