Water Wash Heated Hoses vs. High Flex Heated Hoses

Universal Systems SE manufactures our ClearFlow™ line of heated hoses. ClearFlow™ hoses can be used to transfer many different types of heated materials, however the most common is adhesive. There are two different types of heated hoses that USSE manufactures, high flex and water wash. Water wash, also known as washdown hoses, are manufactured with the same high-quality materials as our high flex hoses, but with a secure water wash connection between the hose and glue head. They are also encased with state of the art, high temperature, extremely durable, waterproof jacketing.

The main question that we get from customers is: why would we need a water-resistant hose? These are not hoses that get submerged under water. These water-resistant hoses, are used in facilities where machines are required to get washed down during or after operation. Hence the name water wash. For example, any type of food manufacturing plant such as ice cream, frozen food, cheese, etc. would be required by the FDA to wash down their equipment regularly. These wash downs impact all of the equipment in the facility, so if you are purchasing a water-resistant heated hose, you will also need a water-resistant gun applicator. The washdown gun applicator will also have the special waterproof jacketing on the cordset and water-resistant adaptor that fits with the hose. As displayed in the picture below.

All ClearFlow™ water wash hoses are manufactured with PTFE Teflon® inner cores and RTD temperature area-sensing. They have a maximum operating temperature of 450 degrees Fahrenheit, maximum operating pressure of 1,500 psi and are 240v. Universal Systems SE manufactures our washdown hoses in multiple lengths that range from 2 feet to 24 feet long.

Preventative Tips to NOT Char Your Glue

One of the most dangerous, yet inevitable, occurrences running hot melt systems in your packaging lines is char. Universal Systems SE has updated technology running in our ClearFlow hoses that reduces char, however the main char that runs through the hoses comes from the tank itself. Once your tank is infested with char, no matter how efficiently your hoses and guns run, there is always the potential to transfer this char onto your packages. You also run the risk of char clogging your nozzles and modules, which can back up through your guns and kill your pumps. Our Universal Systems SE technicians have seen it all. That is why we have created a list of preventative tips that each line operator should follow to effectively reduce char and keep your ProBilt® system running at top capacity.

Preventative Maintenance

Universal Systems Se recommends a complete hot melt system cleaning at least twice a year using our Purge Plus system cleaner.

Contaminated Adhesive

Hot melt adhesive should always be stored in a strong container such as a heavy-duty plastic waste container. Do not set boxes or open bags of adhesive on the floor or on the top of the container. The container should be labeled “Adhesive Only” and include your adhesive part number.

Low Quality Adhesive

With hot melt adhesives, higher price usually means higher quality, the opposite is also true. Adhesive manufacturing is a highly un-regulated industry and many companies use low cost waxes and fillers in their products to reduce cost. These products tend to burn quickly. Due to the fillers and heavy waxes, low cost adhesives can greatly reduce your adhesive mileage whereas high quality adhesives are lighter and have a lower specific gravity. The bottom line is a higher dollar per pound does not necessarily translate to higher packaging costs. We also recommend that you do not mix old adhesives with new brand adhesives. Please read our past blog to help you understand why.

Old Equipment

Hot melt systems are not cheap, so most of the ones in operation today have been on their packaging lines for 10 – 20 years, whether they are running properly or not. That means that most likely, these older machines have char built up in their tanks. It may be time to evaluate the performance and efficiency of your aging equipment and trade up to a new ProBilt®.

Know Your Equipment, Not Just the Part Numbers

The hot melt equipment industry has evolved over the last 40 years. Each manufacturer has made design and material modifications to their product line, which has had a significant impact on the creation and assignment of part numbers. Unfortunately for our particular niche industry there have also been an abundance of variations created solely for clerical purposes. These superfluous numbers make it extremely difficult to place orders and keep inventory organized.

Let’s say you are looking for a single orifice right angle nozzle with a .014 inch diameter hole. The correct manufacturer number can be 244519, 244-519, 244 519, 24-4519US, 320014, 320-014, 320 014, 32-0014US, 1011014, 1011014US, or SR19014. These are all correct manufacturer parts numbers and as you can see the variations are sometimes nothing more than a space or dash. This has already created a very high level of confusion, but wait, it gets even worse.

If you are not purchasing directly from the manufacturer you add a whole other coded level of alpha numeric characters, dashes and mystery spaces. Each buying house has their own system, each aftermarket dealer makes up their own numbers, and even legitimate distributes from time to time will add a character to a part number purely for tracking purposes.

It is important for anyone using hot melt systems to understand the function of each piece of equipment so that there is not a complete dependency on just a part number. We at Universal Systems SE work with our customers to identify parts through a combination of part numbers, descriptions, and photographs. It is especially important to take the time to talk to one of our associates if you haven’t ordered a replacement part in several years or are order a new part for the first time. Our website has a part number search function for your convince; but know you can always call 1-800-848-5018 for personal assistance.

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.
