Using an Adhesive Feeder to Save Money
In today’s world, companies are always looking for opportunities to save money and be more productive.  Whether it is saving money in labor cost or down time, obtaining the right equipment is crucial in the manufacturing process.
For example, a manufacturer that uses adhesive will often come to us looking for ITW Dynatec’s ADS1 Dynafill unit, which is one of the most reliable adhesive delivery systems on the market.  How does this system save companies money you ask?  To start, labor cost and downtime are reduced.  This is a result of adhesive being automatically replenished to the desired level in hot melt equipment, taking away the need for an operator in the hot melt supply unit area.   The automatic replenishment also increases production rates while eliminating the chance of human error.   Repair costs are decreased with system contamination virtually being eliminated and less thermal shock to the system. 

If you would like to see this feeder in action, check out the video below:

After seeing this video, you may be thinking to yourself, “This would be great in our warehouse, but I don’t have a Dynatec unit”.   Fear not, because one of the most unique features is the compatibility with not only ITW Dynatec machines, but also with most competitive hot melt machine configurations.   Many companies love taking advantage of this compatibility trait.

If you are a manufacturer that uses adhesive and adhesive equipment, please feel free to give us a call.  We would love to share other examples and ideas on how to save your company money.

Shipping "Freezable" Adhesives During Winter Weather

Hot Melt Glue - Freezable AdhesiveWinter is almost here! As the temperature drops and the snowflakes fall, we may think of the holidays, sledding, skiing, a warm fire or even getting away to a warmer climate. How many of us think about glue? If you said yes, you are either a glue sales representative, glue manufacturer or need to get a life!

Seriously, if you order, use, or ship glue in the cold months, you SHOULD be thinking about it! While hot melt glue is mostly immune to colder temperatures, water based adhesives are very sensitive to the cold. Since most water actually freezes at 32ºF, your water base glue will too.

But what if your glue arrives frozen? Just let it thaw? It’s not an option! Once water based glue freezes, it’s probably a goner. Emulsion adhesives, contain very, very tiny glue solids which are suspended by a “protective colloid.” This protection keeps the particles, which are heavier than water, suspended in the water and keeps them from settling to the bottom of the container. When the glue is frozen, the particles clump together and/or fall to the bottom. Glue with all those clumps will never be able to stick anything together. Dextrin adhesives, however, are somewhat different.  Because they are solutions, often times they will be usable after some stirring.

So how do you know if a product is frozen? It’s not always easy. The first thing you need to do is to open the container and do an inspection. If you see lumps floating on the top (looks like cottage cheese), ice crystals, or even worse, a solid, it has been frozen. Feel the outside of the container. If it feels very cold, all the more reason to inspect the liquid itself. Get yourself a thermometer and keep it in your receiving department. That way you can determine the actual temperature when you took it off the truck. This won’t be the absolute determination whether it was frozen or not, but if it comes in at 55 degrees or higher, you can probably feel safe that the product is good.

Another quick check is to see when the product was actually shipped. If you buy in a tote tank or 55 gallon drum, the adhesive has a lot of internal heat. That helps to keep it from freezing. So, short overnight trips typically are not an issue. However, if the glue has been on the road for several days, be very cautious and check the adhesive thoroughly. If your glue left from Ohio on Monday and arrived at your facility in Ohio on Friday, you may have a problem with your adhesive – especially if the weather was very cold. That’s why we never ship waterbased products on a Friday in winter months. If we did, the glue would sit in a truck for two to three days and if the weather is cold enough, freezing would occur.

In winter months we always require that freight companies who haul our “freezable” products protect them from being frozen. When they accept and sign for pails, drums or totes, they guarantee that the material will arrive at your location in good condition. If the product does freeze, the shipping company is responsible.

If you ever suspect that a shipment of water based glue has been frozen, be sure to contact us at 440-786-7185 immediately. As an industrial adhesive supplier and manufacturer, we can help you make a determination whether you should accept or reject the product.

What Type of Adhesive Application Is Right For Your Company?

Adhesive Technology | Gluing Equipment | Adhesive ProductsWhether you are using hot melt adhesives or “cold glues,” finding the right type of adhesive application method is essential to meetings your production requirements. Furthermore, choosing how to apply adhesive impacts how much adhesive you will need and how much time and resources applying the adhesive will take. The choices are nearly endless so how do you go about finding the right adhesive application equipment for your company? While it’s best to talk to an expert on the subject (like me), here’s a brief overview of options for different industries to get you started.

First off, the choice to go with an automated or semi-automated adhesive application system versus a manual adhesive applicator, such as a hot glue gun, depends greatly on the amount of production, time and resources available. In the long run, it is usually more cost effective to use an automated system because it will use less glue, take less time, use less manpower, make fewer errors and require less clean up. Even with more complex designs or ever-changing requirements, you’ll be surprised at how well an automated system can handle both.

Our top equipment partner, ITW Dynatec®, is a global leader in automated adhesive application equipment, especially when it comes to hot melts. Their systems offer a wide variety of dispensing and applying adhesives at just about any price-point. Applicators include bead, slot and spray patterned technologies for precision metering and joining. Industries served include packaging, paper converting, product assembly and non-wovens. ITW Dynatec’s adhesive application systems—from adhesive feeders and supply units to pattern controllers and automatic applicators—can be configured to your exact specifications no matter what your needs.

ITW Dynatec Hot Melt Bag Laminator to seal bags | Glue Machines | Hot Melt Glue

For simpler intermittent or continuous form operations, there are roll coaters, also called roll applicators, that are self-contained and low-cost options for packaging, sealing, product assembly and textile or paper converting. Our roll coaters can be used for both cold and hot glues in roll sizes ranging from 6” to 50”. In addition, we distribute ITW Dynatec's hot melt bag laminator with a minimum 72” roll stand that allows for interchangeable module deigns to quickly and effortlessly seal bags.

Lastly, there are manual applicators, such as a glue gun or a wand dispenser. Often used for smaller operations or highly intricate work, manual adhesive applicators like the DGII™ from ITW Dynatec® have been designed for flexibility in low volume application that don’t need glue sticks and can work with an adhesive feeder for continuous supply. In addition, we sell two stand-alone industrial hot melt glue guns directly from our eBay store that include its own container for granules or pillows to easily keep up with workflow needs.

As you can see, the options are many so that you can determine the best fit for your company. Our HAR Equipment division can even custom design, build and install adhesive application machines and systems for your specific needs. To find out more about all the options or to discuss your production needs with an expert, I’m just a phone call or email away.

The Use of Thermal Mastics in the Appliance Industry
Have you ever wondered why certain appliances with motors do not overheat?  Or why you can touch the outside of those appliances and not get burned?  While many different factors contribute, one of the key reasoning’s is the use of thermal mastics.

Thermal Mastics are smooth, pumpable heat transfer compounds that act as gap fillers.  They can be used for different applications in which surface to surface heat transfer would aid in the system or component' performance.  Commonly used in the appliance industry, thermal mastics are involved in the manufacturing and operating of freezers, air conditioners, and refrigerators.  The function of the application in this industry is to increase the surface area for the transfer of heat away from heating or cooling coils thus causing improvement in coil efficiency.  In refrigeration for example, they can be used to transfer heat from the evaporator coil to the heat sink, temperature sensor or the defrost thermostat.  It is less costly than soldering or brazing and allows coils to be attached to liner walls with low cost mechanical fasteners.

There is not one specific way thermal mastics should be applied.  Depending on the volume, they can be applied with hand tools, caulking guns, or suitable pumping systems.  Temperature, pump pressure, and nozzle size can impact the efficiency of the application.  Using mineral spirits to cut or dissolve the product can make for an easy cleanup.

If you are in the appliance industry and are looking for a mastic product, please feel free to contact me.  I would be happy to help solve your problem and offer support beyond your imagination!

Not Fully Supported By Your Adhesive and Equipment Supplier?

What kind of support should you expect from your Hot Melt Adhesive Supplier and Hot Melt Application Equipment Supplier?  What if they were the same company!

Getting the necessary support from your adhesive and equipment supplier can be crucial to running an effective and efficient packaging operation.  Yet, many companies that use these products may not even know what is possible!  It’s safe to say that not every company operating in a hot melt packaging environment has experts on their staff at detecting or solving adhesive application issues.   This lack of knowledge can make it very difficult when a problem arises.  Further, at a time when adhesive choices are greater and technology is becoming more sophisticated, we are finding more and more that hands on support from suppliers is rare or non-existent. 

Recently we were in contact with a very sophisticated warehouse that does repackaging and distribution for a very well known brand.  They were kind enough to invite us in and to show us their packaging operation.  Within seconds we could see that they were not receiving the proper support from their current suppliers.  The facility contained 7 packing lines, with 3 gluing stations per line.  While observing the lines, we noticed two different problems immediately.  The first problem was that the adhesive being applied to the case was being dispensed improperly, causing it to string or cobweb.  The second problem was the excessive amount of glue being applied.  Most people would believe that this was just a glue issue, but we knew we had to take a closer look at the equipment as well.  

We found the company was using very old Nordson equipment.  Upon further questioning, we learned that the lines were often down due to adhesive related issues, maintenance costs were high, and the correct replacement parts were extremely difficult to find.   We were invited back to perform a more extensive analysis of the operation in which we included a member of our equipment team.  Our proposed solution was to begin using a Dynamelt SR Unit that, quite frankly, seemed extremely optimistic to the customer.  To show our confidence in our solution we offered them a 90 day trial for one of their lines.  After 90 days they reported that the transition was smooth and the equipment worked just as we promised!  The operation was running much cleaner and the glue was no longer stringing.  They are finding the equipment is paying for itself with less down time, less stringing and less adhesive usage per carton.  
If you are wondering if maybe you are not getting the support you deserve or you are not sure "what is possible", please give us a call.  We would love to help solve your problem and find a solution beyond your imagination.

Where to Go When Stitching Your Adhesive is Wearing out Your Modules

Stitching adhesives is a practice that can offer advantages in some industries.  Instead of applying adhesive in one long bead, companies will “stitch” or use small dots of adhesive to cut glue usage and to cut glue costs.   One of the main components of the stitching process is the module.  A few months ago a manufacturer of pleated filters, who was stitching, came to us with a module problem that they could not solve. 

In their process, each glue module was running millions of cycles per week.  The constant opening and closing of the valve was causing the module to fail frequently. This failure was causing scrap, downtime and replacement module costs.  Instead of asking the customer to stop their stitching process and double the amount of money spent on glue, we came up with a solution.  Our suggestion was to enhance the valve to a higher quality product.  We recommended the ITW Dynatec Marathon Module.  This product has proven to be a long lasting and reliable valve.  After replacing their module with our Dynatec marathon module, they eliminated glue dispensing problems in production.  The valve is still being turned on and off millions of times per week but is causing zero problems.  The company converted to the Dynatec valve over a year ago and their module failure problem has been resolved.  The upfront cost of the marathon module was a little higher but that cost was more than overcome by the savings.

Do you have a challenging adhesive or application equipment related problem that you think cannot be solved?  If so, please feel free to give us a call.  We would be happy to go through your process and help you find a solution that goes beyond your imagination!

Going Beyond the Glue

A couple of months ago, a state-of-the-art food processing plant in Ohio started having problems with sealing containers and other gluing issues. As their adhesive supplier, they called us with concern that the adhesive was a different product, a new formulation or even a bad batch.

When you have been using the same adhesive without fail for several months or years and then it starts to fail, you may think there is a problem with the adhesive. More often than not—which was the case for this company—it is actually the adhesive application equipment. That’s where our Equipment Division comes in handy!

Looking at their operations, we noticed they were using Nordson applicators. These applicators were misfiring and misaligning the hot glue which resulted in their containers not getting sealed properly. To compensate, they were using more adhesive to try and correct the problem, which caused a lot of stringing and a lot of waste. When it comes to proper adhesion, using too much glue actually makes the problem worse.

The solution was a simple one and they could not be happier. We changed their applicators with ITW Dynatec BF MicroBead™ applicators which is a perfect and cost effective fit for any Nordson machines. As stated by their production manager, not only has their downtime has been dramatically reduced but their glue consumption as well.

Are you having a problem with your gluing operations? We would be happy to come in and take a look at your entire operations and work with you to find the best solution for your company.

Indispensable Types of Adhesives

There are so many seemingly small yet -in today’s world- indispensible inventions that use adhesive as a main component. Take a look in your home or office, what would we do without transparent tape, sealable envelopes, adhesive bandages or disposable diapers?

These inventions were often created to solve a problem or improve a product. Take furniture pads, for example. Many years ago a young inventor tried to find a solution to stop his chairs from marring the floors. He found that if you soak the thick felt material used for chalk board erasers into a high solids white glue, once hardened, it can be used as pads on the bottom of furniture to protect the floor from scratches.

Sometimes, however, the invention is by sheer accident as in the case of sticky notepads. In 1970, a 3M Adhesives researcher tried to create a super glue-like adhesive, but instead only developed an adhesive that would stick paper together. The invention got shelved until years later when another 3M Adhesives worker was singing in a church choir. He used bookmarks to keep his place in the hymnal, but they kept falling out of the book. Remembering the sticky but peelable adhesive, he coated his bookmarks with it and, voila, Post-It Notes® were born.

Can you think of other clever inventions that have required adhesive solutions as a main component?
