Under Pressure: How changing air pressure impacts your hot glue lines

Universal Systems manufactures pneumatic hot melt systems, which means that our equipment operates via air pressure. It is important to understand how air pressure can put stress on equipment and why the correct pressure points are essential to run a consistent, well-maintained hot melt system.

The way that a pneumatic hot melt system works is that an airline goes into the pump, to move the pump shifter, air motor and pump piston up and down to pump the glue from the tank, through the manifold, through the hoses, into the guns and onto the boxes. There is also going to be another air line into the guns to get the module pistons to open, apply the glue, and in some cases there will be an additional air line the air to close the pistons.

Let’s start with the air pressure to the pump. The air pressure to the pump is very important and should always be set between 20 psi – 40 psi, with an ideal setting in the middle at 30 psi. If your technician thinks the pump is running too fast and lowers the psi to under 20, then the pump might not have enough pressure to move the shifter. In most cases, a pump will run at as low as 18 psi. If your technician comes to you and states that the pump was running too slow, so they increased the air pressure to over 40 psi, that could cause damage to the seals inside the pump’s air motor. It is important to note that if the air pressure on the pump is set to 40 and the pump is still not pumping efficiently, then there is another issue at hand. Most likely there is dirty air inside the shifter or a clog in the tank filter. The air pressure should never be increased to fix other issues stopping up your pump.

The second air pressure point in your hot melt system is at the applicator gun. The air going into the gun should be set at a minimum of 60 psi. In most cases, 60 is the perfect setting for the guns. If your technician tells you they need to set the psi higher to get the guns to fire, then there is a clog in the in-line filter and that filter should be replaced. If the psi to the guns is anything higher than 80, you could blow a seal on the module and have issues with application.

Are you running a Nordson® ProBlue®?

If you are running a Nordson® ProBlue®, then you might be worried about how long it’s been taking you to get parts for your tank. You should be. Recent reports from industry insiders are calling out the 3-month lead time on Nordson® ProBlue® tanks and parts. The same industry insiders are confirming that Nordson® has decided to discontinue their most popular line of hot melt tanks.

What does that mean for you?

Currently, the only facilities who are running into an issue are the ones who need new hot melt tanks. Without the ProBlue® as an option, your next best Nordson® tank is the Flex®, which can run you upwards of $20K. That is where we come in. Universal Systems SE has a line of high quality, low maintenance, affordable, reliable hot melt tanks called ProBilt®. Our ProBilt® line of hot melt tanks are designed to be an easy to use, plug and play style machine, with interchangeable parts no matter what capacity size pot you order.

Cold Weather Impacts Your Hot Glue

Most facilities are located in parts of the US impacted by the cold weather months. As the weather gets colder, so does the interior of the factories where most packaging lines operate. It seems like common sense that as the environment around your hot melt system gets colder, so will your hot glue unless you increase the temperature. Below are a few key factors to realizing you need to up your temperature.

Hot Melt Consistency

Hot melt consistency is the number one problem in most high-speed packaging lines during the winter months. This includes not only the consistency of the glue within the heated reservoir, but also the consistency of the glue to stay at temperature as it travels down that line. Just because your glue looks viscous inside the pot, doesn’t mean it is holding the same viscosity throughout the travel process. If your glue looks stringy or your guns are not firing consistently, then you most likely have a glue temperature problem. Try increasing the temperature of the tank, hoses and guns by 15 degrees. Please note that your hoses and guns should already be set 15 degrees higher than your tank. A minor adjustment like this will not char your glue, but should help keep it consistently viscous throughout the travel process.

Locate Cold Joints

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 you cannot eliminate cold joints, increasing the temperature settings of the tank, hoses and guns will be helpful.

Location of your Line

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. Since you cannot move the line, increasing the set temperature of your tank, hoses and guns will help eliminate glue inconsistency during the winter months.

Universal Systems Plug & Play Machinery

With what some industry professionals are calling “The Great Resignation” driving the packaging industry, it is so important to have equipment that is easy to use and operate. Recent studies report that the labor shortages in the packaging industry are due to employees not returning to work after Covid-induced shutdowns, as well as the increase in quit rates with most new employees not lasting longer than a month. Food industry production lines are reportedly standing idle because of lack of staffing where processors specifically pinpointed high retirement rates. This is a hard reality for many CPGs, and consumers are seeing this direct result in our local grocery and retail stores.

With over 40 years of experience in the hot melt packaging industry, Universal Systems is here to help. We have worked with hundreds of new maintenance managers and plant managers to help them learn about the equipment they are running. Whether they are running a competitor tank with our USSE components or our ProBilt system, we have the skills and knowledge of both old and new equipment to help relieve some of the stress that many companies may be feeling due to the loss of their most experienced workers.

Many CPGs also cite a lack of skilled labor capable of operating and troubleshooting complex packaging machinery. This is why Universal Systems’ line of ProBilt equipment is the perfect match for these end users. Our ProBilt equipment is in fact plug and play, with the easiest controls in the industry and the most flexibility by offering up to a 4-hose capability on all tanks. While many of our overseas manufactured competitors spent the last five years releasing “upgraded” equipment, they have lacked the foresight to see that they have ultimately overcomplicated the machinery for end user operators. Universal Systems’ ProBilt tanks have not changed much in the last 20 years. We have continued to manufacture our easy to program Accuscan control board and standardized components that we have prided ourselves on. Here at Universal Systems, we believe in quality, longevity and sustainability. Our products have proved time and time again that they work hard, for a long time, and without much training needed.

In addition, CPGs have been requesting more online videos and tutorials to help them train their new workforce on the machinery in their packaging lines. Universal Systems has listened to this call and we offer videos online on how to set melter temperature, as well as how the setback functionality on our tanks work.

We are here to support all of our customers, both old and new, as they navigate through their workforce troubles. By stocking over 10,000 items, we also help keep our customers up and running so you don’t have to wait out long lead times for standard operating equipment.

ProBilt Glue Systems Meet the Demands & Needs of Packaging Lines

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.

  • Quick changeovers to limit downtime – USSE’s ProBilt systems are plug and play. They are easy to set up and disable for cleaning, preventative maintenance, component replacement, etc.
  • Preventative maintenance schedules – USSE believes that preventative maintenance is key to maintain the efficiency and longevity of any piece of machinery. A hot glue tank is no different. Universal Systems offers up a preventative maintenance schedule upon request, along with recommendations on what parts to keep on the shelf and how many of each part is needed to keep your operation up and running at all times.
  • Streamlined equipment so that system components are interchangeable – Universal Systems prides ourselves in being the most streamlined OEM of hot melt machines in the market. Not only do all of our tanks take the same pumps, filters, valves, etc., all of our components are interchangeable with our top competitors including hoses, guns, modules and nozzles.
  • Versatility for different packaging setups – Universal Systems manufactures over 100 different types of applications options, as well as the option to custom CNC any configuration needed.
  • Easy-to-operate machines – Our ProBilt tanks are by far the easiest in the industry to operate. We focus on longevity and simplicity so that anyone can set up and operate our tanks with ease. We also offer online videos on how to set temperature and utilize our setback feature.

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.

The Right Melter for Your Packaging Line

Finding the right melter for your packaging line can impact not only your productivity, but also your bottom line. Most commonly, maintenance managers and buyers simply replace the current OEM melter with the latest model. That is not always necessary. Universal Systems SE ProBilt™ melters have the same footprint as most all Nordson® systems and can easily fit into where the original tank is positioned. Just because your current packaging line has a Nordson® melter does not mean you have to replace it with another expensive Nordson®. Plus, all of our ProBilt™ melters are in stock and can ship same day!

There are several key points to take into consideration when choosing a hot melt system for your packaging line. The most important are: Melt Rate, Durability, & Cost-Effectiveness.

Melt Rate

The melt rate is the rate at which the tank melts the adhesive pellets as they are filled into the reservoir. This is where the tank capacity comes into play. Before moving forward with any hot melt adhesive system, first you need to understand how many pounds you need to melt per hour. The melt rate is dependent on how many hoses and gun applicators you are running and how many boxes are being sealed per minute on your packaging line. The most common tank capacity is the 20 lb. (10 Liter) ProBilt™ 20, with a melt rate of 23 lbs. per hour. If you are only running one line with one hose and gun applicator, then you may only need the 15 lb. (7 Liter) ProBilt™ 15 which melts 18 lbs. per hour or the 12 lb. (6 Liter) unit which melts 15 lbs. per hour.

Durability

Depending on how many shifts you are running, you need a melter that will work consistently and effectively. All ProBilt™ melters come with a 10-year heater warranty, which is the highest in the industry. In addition, all melters come standard with 4 hose / 4 gun capability and a set-back functionality that allows for easy start up and shut down. ProBilt™ melters are constructed out of 316 stainless steel, not only for its sleek look that will seamlessly blend with your packaging line, but also for its durability and sustainability on your production line floor.

Cost-Effectiveness

The economy is a huge question mark lately, being impacted by the lasting effects of the COVID-19 pandemic. With that, large CPGs are cutting back not only in personnel but in spending budgets for packaging. These tighter budgets won’t always allow for a buyer to simply purchase the latest Nordson® melter. Here at Universal Systems SE, we have seen more and more companies trying to repair older melters and plug any current issues with band-aids to stretch their fixed budgets as far as they can. Since we manufacture parts that are compatible with old Nordson® tanks, we have been able to help a lot of companies cost effectively navigate the times. In addition to our parts business, all of our ProBilt™ series melters are cost effective replacements for any Nordson®. We are currently running a 15% off and free shipping in the USA promotion to help out CPGs and support US based companies.

To learn more about Universal Systems SE’s ProBilt™ series of melters and components, please reach out to a customer service representative at sales@ussefl.com or call (561) 272-5442.
