The Importance of Using Aluminum for Manifolds

Universal Systems SE manufactures high quality hot melt application manifolds that will work with most all hot melt application systems. We understand the importance of durability, consistency and effectiveness in packaging manufacturing, which is why we use 6061T aluminum when making all of our manifolds.

What is a Manifold?

When evaluating what you need for your hot melt application system, it is important to understand each item that makes up the application gun. The manifold is the aluminum gun body, that houses the heater & sensor, and is where the modules mount.

Why do we use Aluminum?

Aluminum is used on all of our hot melt applicator manifolds because it is an excellent conductor of heat and dissipates heat very efficiently. Aluminum also has a very high strength to weight ratio, meaning that although it is light-weight, it is extremely strong. Its strength is what allows for peak performance during the rigorous packaging process.  It is also non-toxic, cannot burn and is easily recyclable.

Why do we use 6061T Aluminum?

All of Universal System’s ProBilt™ manifolds are manufactured using 6061T aluminum. 6061T aluminum is aviation aluminum and used for the building of all jet aircrafts. This will extend the lifespan and durability of the manifold and increase it’s on the floor performance.

How to Keep Old Melters Operable

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.

Pneumatic Pumps

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.

Actuator

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.

Tank Filters

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.

Same Footprint

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.

Managing Your Glue Usage in Packaging

Hot melt adhesive is not cheap and you may notice that the prices are only going up. What purchasing agents might not know, is that a lot of packaging lines are using more glue than is actually needed. There are a few simple ways to manage your actual glue usage and help cut costs to manage your budget.

Nozzle Diameter

The first step in managing your glue usage, is knowing the diameter nozzle tip you are using in your packaging lines, and understanding why you are purchasing that size. A lot of times, our sales reps will get calls from customers that want to buy larger size nozzle tips because their line operators are saying there is not enough glue being released on the cartons. Obviously, as you increase your nozzle tip diameter, the more glue you are going to use overall and increase your yearly costs for adhesive. This can also cause several other issues, such as potential sealing issues if the hot adhesive does not have enough time to dry as it moves along the cartoner. If your line operators are asking for larger diameter nozzles, question them as to why.

Evaluate Set-up

If your line operators are stating that the glue is not keeping the packaging closed, which is why they need larger nozzles, evaluate your setup. Check the distance your gun applicator is to your carton and at what temperature you are heating your adhesive. If the adhesive is not hot enough and your gun is too far away from the application site, the adhesive could be cooling before it even hits the carton which is why it is not creating a tight seal. Simply increasing your heating temperature or moving your gun applicator closer to the end application site could solve this issue. You could also be putting down too much glue already. If you have a high-speed packaging line, and put down too much glue, the speed will not allow time for the large amount of glue to dry.

Change Your Filters

Another simple solution to managing your glue usage, is to check both your tank and gun filters. If your nozzles are clogging frequently, causing the line operators to buy larger diameter nozzles, they may be clogging due to char. Char is a typical occurrence in hot melt packaging, but the transfer of most char can be prevented by regularly changing your tank and gun filters. These filters will extend the life of both your modules and nozzles.

Low Profile Glue Guns

Low profile guns are one of the most commonly used gun on cartoners. They come in 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.

Even though the low profile guns look different than a standard gun applicator, they use standard H200 modules. This allows you to use the same modules and nozzles that you run on all of your other types of glue gun applicators. With both our two module and four module low profile gun, the modules are set with .88 inch centers and are a air-open, spring-close. The most commonly used nozzles for low profile guns are one or two orifice, right angle nozzles.

A few of our customers have asked over the years if Universal Systems SE manufactures a one module low profile gun. The answer would be no, however we can insert a custom module blank to the two module low profile gun, effectively turning it into a one module applicator. An advantage to this is that our custom module blank is removable, in case you ever change up your packaging line and need a two module low profile gun.

The item numbers for our Universal Systems SE ProBilt™ low profile gun heads are item # 3281 for the two module version and item # 3471 for the four module version. If you are interested in learning if your packaging line runs low profile guns compared to standard glue applicators, or the advantages to switching to a low profile gun, please call (561) 272-5442 or email sales@ussefl.com.

The Growth of Hot Melt Adhesive Systems

Unlike water and solvent based adhesives, the adhesives used in a hot melt system do not require any dryer after being applied. This gives these machines a unique and efficient advantage over other types of adhesives being used. Also known as “hot glue,” hot melt is a thermoplastic adhesive that begins to bond as soon as it’s applied to the object due to it being able to cool down to its solidification point almost immediately.

Who Benefits With Hot Melt Adhesive Systems?

Hot melt adhesive is ideal for those who work throughout several industries. This type of adhesive equipment is ideal industrial applications that include, but are not limited to:

  • Bonding versatility.
  • High-speed manufacturing.
  • Minimal shrinkage.
  • Large gap filling.

Within the packaging industry, hot melt adhesive systems are extremely popular because they allow for major applications to be accomplished in a faster time while increasing production value. Whether you work in construction, woodworking, stock and tape manufacturing, bottle labeling, or any type of bonding industry, this adhesive system can only benefit your business.

Using a Hot Melt System

With a majority of hot melt glues being composed of polyolefin compounds, acrylics, polyamides, and urethane materials, there’s no need for any pre-surface treatment when you begin bonding. Hot melts are easy to apply systems because the only process is turning a solid into a liquid then it immediately turns back into a solid (remember: no dry time). Although durable and long lasting, this type of adhesive is easy to repair by reheating and re-separating.

If you think a hot melt adhesive system can benefit you and your business, contact us at Universal Systems and we can inform you of the equipment that has the best benefits in terms of what you’re attempting to achieve.

Hot Melt Adhesive Equipment: Troubleshooting Tips

Whether you’ve already invested in hot melt glue equipment, or you’re considering it, knowing how to troubleshoot any potential problems is highly advised by any hot melt adhesive machinery as well as equipment distributors and manufacturers. However, before we get into common troubleshoots; let’s define what hot melt adhesive systems actually do.

What is a Hot Melt Adhesive System?

Hot melt adhesive systems are composed of different pieces of equipment that come in a variety of pump, hopper, and hose gun connection sizes in order to satisfy your individual production needs. Hot melt glue machinery can be used to assist several different industries including, but not limited to:

  • Bookbinding
  • Breweries
  • Graphic Arts
  • Labeling / Laminating
  • Packaging

Troubleshooting Mechanical Problems With Your Hot Melt System

Now, we don’t advise that you should try and troubleshoot a hot melt dispensing unit on your own unless you’re a qualified professional. If you are a qualified professional, observe and follow the safety instructions within your OEM manual that you were given for your specific machine.

  • IF YOUR PISTON PUMP ISN’T WORKING PROPERLY

    First, check to see if the unit has reached its operating temperature, if it has, then there could be a problem with your air supply, the solenoid valve, or there’s something wrong with the assembly of the shifter valve.

  • IF THE PISTON PUMP IS STROKING ERRATICALLY

    If this problem is occurring, then you may be low on adhesive, if you’re adhesive level is fine, then check to make sure that the adhesive is actually melted. You’ll also want to check the pump seats in case anything became lodged within them, as well as make sure that the o-ring in the crossover tube isn’t broken.

  • IF THE GEAR PUMP IS NOT PUMPING PROPERLY

    One of the first things to check if your gear pump is not pumping properly is the motor. If the motor is not running, you want to check the motor control as well as the capacitor. If you don’t see anything wrong with the motor than look for any fault indicators, as well as making sure that the pump ready light is on. In the event that none of these tips help, then there may be a blown fuse.

  • IF NO ADHESIVE IS PUMPING OUT

    If your motor is running, but there’s no adhesive being pumped out, then you’ll need to check your adhesive levels and make sure it’s melted. There’s a chance that the nozzle could be clogged on the head however, if it’s not then you’ll need to check the inline head filters, the tank filters, the coupler between the motor and the pumped, and the pressure regulator.
