Top 5 Tips to Hot Melt Machine Maintenance

Packaging lines are complicated pieces of machinery and knowing the ins and outs of each component is important. When you install a new hot melt system onto your packaging line, there are 5 helpful tips to take into consideration to ensure smooth operation and getting the most out of your equipment.

Read and Keep the Manual

The best practice for maintaining your hot melt tank is to read the manual and keep it handy. So many times, maintenance managers will install the tank, but not read the instructions on how to wire it or program it. That can lead to so many issues. In other instances, a tank may be running for some time, but someone hits a button accidentally and changes a setting, then doesn’t know how to change it back. If only they had read the manual or kept it on hand. It sounds like such a common-sense thing, but oftentimes manuals are discarded with the shipping crate. For this reason, we keep a digital manual on our website for anyone to reference.

Replace the Filters

Preventative maintenance is one of the most important tasks to keep your machine running efficiently and reduce down time for your packaging line. When your tank filters are clogged, that is good, it means that they are doing their job and filtering out char. Changing them on a regular basis and spending a small amount on a tank filter will save you thousands in the future.

Monitor Your Hot Melt System

Line operators are tasked with monitoring tanks on a daily basis. It is important to make sure that the pump is pumping smoothly, the solenoid is not lagging and the guns and hoses are heating to temperature and staying there consistently. Even a minor change in any of those tasks can mean that it is time to proactively replace a component, or at least make sure there is a back up on the shelf.

Know Your Options

Knowing your options ties all three previous tips together. If you have read the manual, you will know what your options are when something goes down. If you are doing preventative maintenance, then you know it is not the tank filters. And if you are monitoring your system, you know what components you replace most often and what inventory you have on the shelf. In addition, you should also know what options you have should you need to replace your current system. Is the current technology working for you or do you want to upgrade to an auto-fill system? It is always good to be prepared and know your options.

Listen to Your Workers

Line operators are on the front lines, literally. They watch particular lines and machines on each line all day, every day. They know what parts are running effectively and where the problems may lie. It is important that you listen to them. They might not be the maintenance manager by job title, but they are the most knowledgeable about the equipment they are in charge of and their opinion should be the first requested.

Know Your Strengths

Knowing your strengths and the value add that you provide are important keys to success for any business. Universal Systems SE’s strength is the in-house manufacturing, QA process and customer service that we provide to our customers all year. The value add is the high-quality material and product that we put to market at a more affordable rate than most of our competitors.

Every day we have maintenance managers or co-packers calling in to find out if we can support their old Nordson® tank. The simple answer is yes. We can support old melters and usually fix any issues that your hot melt applicator may be having. On our website, we offer a search functionality that cross references thousands of product IDs from other manufacturers to make it easy to see which USSE parts are a perfect fit for your old system. However, not only do we support the old, but we manufacture new equipment that will function the same as your old and hopefully last longer. In order to help increase the life expectancy of your hot melt equipment, we offer a recommended maintenance schedule for any maintenance manager so that they can keep up with the life of their products and know when to replace important parts.

Another value add is the fact that we stock over 10,000 items at all times. Not only do we have hundreds of different styles and diameter nozzles in stock, we also stock pumps, control boards, filters, hoses, applicator guns, modules and we always stock tanks. Unlike most manufacturers, that make to order tanks, hoses and guns, we have one of the largest in stock inventory of any other hot melt manufacturer. And everything ships from the US, which means that you can typically get it within the week or overnight service if needed.

If you are ever in need of technical support for your old melter or hot melt equipment, do not hesitate to call us at (561) 272-5442. We are here to use our strengths, to help you add value.

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.

When You Should Use a Pattern Controller

Pattern controllers come on the packaging lines themselves and not typically with a hot melt application system. But, while it is not something that many hot melt manufacturers make, it is very important to the glue application process.

Pattern controllers are used for specific glue applications and patterns. The latest pattern controllers have 4 channel controller capability to do both time and distance-based application programming. They can store up to 9 programs and have the capability of operating in “stitch mode” for substantial glue savings. Another unique feature is the low speed cutoff in distance mode to keep the glue off the side guides when the machine is slowed.

So, when do you need to use a pattern controller and which options do you need? Below are the definitions of both constant speed and variable speed controllers to help you figure out which option is best for your application process.

Constant Speed

Constant speed pattern controllers are also known as time-based controllers. The glue is dispensed consistently between .001 – 9.999 seconds, depending on the time that you set. They are designed to trigger a 24VDC Solenoid Valve and have on the fly program adjustments, so nothing is set in stone. Most constant speed pattern controllers have up to 4 programmable glue pattern events available and up to 9 programs can be stored in memory and remain in memory even after the system is shut down.

Variable Speed

Variable speed pattern controllers come with an encoder and are also known as distance-based. This means that the glue can be dispensed in set distances apart from the last application. Variable speed pattern controllers measure in tenths of inches, trigger a 24VDC Solenoid Valve and the encoder offers 1200 pulses per revolution. There is a low speed cut off and easy to use program adjustments. Like the constant speed controller, the variable speed controller has 4 programmable glue pattern events and 9 programs can be stored in memory and remain in memory even after the system is shut down.

There is also a hybrid version pattern controller that allows you to do both constant speed and variable speed.

To learn more about pattern controllers, their benefits and which one is right for you, please call (561) 272-5442 or reach out to a Sales Representative at sales@ussefl.com.

Chillers on Your Manufacturing Line

Now you may be asking yourself, why am I reading about chillers on a hot melt blog? The answer is easy, Universal Systems SE manufactures heated hoses that can be used for transferring many more substances other than glue. And when there are applications that do not include glue, the manufacturing lines may need chillers.

Our heated hoses, while mainly used for high speed packaging glue application, can also be used for heating and transferring a plethora of other materials. Our Teflon lined hoses can transfer anything from candy, make up, wax and much more! Depending on the use and application of different substances, the packaging line can be filling at high rates of speed. Heating and filling formed containers for candle wax, as an example, can be tricky because in this application the wax needs to cool quickly so that it can be formed, packaged and shipped out to end users. One of the most common questions we get in this situation is: How can I keep my forming operation running at a high-speed pace from start to finish? The answer here is chillers. Essentially how a chiller works is it is built into the conveyor line. So, the product would be heated in a melt pot, transferred through the heated hose, dispensed into containers, and then fed along a chiller that is built into the line. The product goes from hot to cool in a matter of seconds.

If you have any other questions on how we can help you keep your production lines running at high-speed capabilities, please reach out to sales@ussefl.com or call to speak with a technician (561) 272-5442.

Hot Melt Glue is Not Just for DIY Projects

Hot melt glue is a thermoplastic adhesive that melts and flows when heated and solidifies when cooled. Most of the time, when someone mentions hot melt glue we think of do-it-yourself craft projects. However, hot melt is actually used in many different industrial applications because of its drying time, shelf life, and bond strength.

The drying time for most hot melt products is nearly instant. As soon as the adhesive product is dispensed from the applicator the temperature rapidly falls and begins to turn back to a solid state. A great example of the final result is the dots of glue that hold together the top of cereal boxes. Hot melt can adhere to nearly any kind of material and creates an immensely strong weather resistant bond. Most products held together with hot melt will stay for years, which is another reason why hot melt is used instead of other water based adhesives.

Companies across the globe take advantage of these traits and use hot melt for bookbinding, lamination, automotive assembly, appliance manufacturing, even the creation of diapers and air filters. Not to mention, it is the most convenient and widely used method for sealing boxes. We often encounter hot melt on primary packaging like the boxes that protect products like frozen food, cosmetics and toys. These boxes are actually shipped in layers of secondary packaging like inside corrugated cardboard cases or palletized, both of which use hot melt.

The technology used to heat and apply hot melt continues to change, but the overall need and use of hot melt remains the same. If you would like to increase efficiency and add hot melt equipment to your packaging application, please give us a call or send us an email.
