Melt-on-Demand Technology : The Original "Tankless" Melter
From fully automated production lines to manual assembly applications, adhesive hot melt supply units continue to be a vital component in the manufacturing process across a variety of industries.  In order to ensure that adhesive supply units function effectively within a process, new technologies are being introduced to reduce, minimize and prevent adhesive related stoppages to production.  One of the most common failures experienced in adhesive hot melt systems is char.  Char occurs when hot melt is (1) exposed to excessive temperatures and is (2) exposed to heat and oxygen for a prolonged period of time.  Melt-on-Demand technology, innovated by ITW Dynatec, has effectively minimized occurrences of this issue and has been a vital feature of ITW Dynatec adhesive supply units for decades.  Recently, new “tankless” adhesive supply units have been introduced and offer many features and benefits similar to ITW Dynatec’s systems outfitted with Melt-on-Demand technology.

ITW Dynatec Melt-on-Demand History
You probably weren’t thinking of Melt-on-Demand technology in the 1960’s, but luckily the innovators at ITW Dynatec were!  At the time, most adhesive supply units had a uniformly heated reservoir/hopper that essentially cooked the glue at the same temperature throughout the reservoir.  As mentioned above, this method created an environment ripe for generating char and damaging/blocking various components of the adhesive supply unit.  In order to combat this problem ITW Dynatec created a system that only heated the glue to the maximum temperature prior to its application.  This ITW Dynatec technology has been refined over the years and continues to stand guard at the front lines of combating char. 

The “Other” Melt-on-Demand Technology
Like all great ideas, other adhesive supply unit manufacturers have attempted to mirror the feature of Melt-on-Demand technology.  Recently, these manufactures have unveiled “tankless” adhesive supply units that boast the same capability of reducing char. A tankless system may be a good fit for your production needs, however, there are certain limitations that are presented.  Due to the small reservoir, tankless systems require an adhesive hopper feeder, which can maintain a constant flow of solid adhesive to the reservoir.  However, if the hopper feeder ever fails, constantly filling the low capacity tankless reservoir would be a near impossible task.  Using a hopper feeder also limits the form of adhesives that can be used.  Hopper feeders use a tubular vacuum system to supply the reservoir and require pelletized adhesives to function.  Adhesive in other forms such as pillows and chips are not suitable for hopper feeders supplying tankless systems.  New tankless systems also typically come at a premium.  Purchasing one of these systems will likely cost a company 30% more than a similar ITW Dynatec system with similar Melt-on-Demand technology.  Manufacturers of tankless systems advertise that these systems can achieve the set temperature 10 minutes after start-up.  This is a great feature to reduce production start-up time.  ITW Dynatec systems do take longer to heat up to set temperature, however, many ITW Dynatec systems are equipped with seven day schedulers to automatically begin the start-up process prior to the arrival of the operator.

Choosing the Appropriate System
Companies must now navigate through a wide variety of adhesive supply units to determine a system that will be the best fit for its operation.  A system must be reliable, supportable (parts, maintenance, and service support) and be capable of meeting the demands of the production line or application it supports.  The right system can assist with efficient production which typically translates into greater profits.  (Your local HAR Adhesive Technologies representative is willing to assist you with identifying the appropriate system for your needs).  The bottom line is that Melt-on-Demand technology, pioneered by ITW Dynatec, is still relevant and can help your company mitigate char and meet your adhesive application needs.

Production Solutions & Building Relationships with Adhesive Equipment Advancements
A few years back, I visited a large cosmetics manufacturer who requested HAR’s assistance in improving a minor portion of their production.  Upon arrival, I was asked to carefully observe their entire process and determine which area I could potentially help optimize.  After a thorough inspection, we decided to run a sample test using a different type of adhesive equipment.  ITW Dynatec’s ADS1 DynaFill is one of the most reliable adhesive delivery systems on the market and is known for cutting manufacturer’s labor costs and downtime significantly. After a successful sample run, the manufacturer agreed to do several trials on site and were very pleased with the results. So much so, they decided to purchase approximately 20 more of the ADS1 DynaFill systems!

With the switch to this system, production rates would increase, while eliminating the possibility of human error simultaneously.

As months passed, I revisited the manufacturer to confirm the units were working properly, and to see if I could be of any more assistance.  To my surprise, I was informed that they were having issues with their Nordson hot melt machines that they use for a different product. Upon inspection, I noticed the Nordson glue applicators were not functioning properly.  The guns were misfiring, which caused the adhesive to string and drool.  I was told that the issue has been a concern for a while, but Nordson was of no help in correcting it.  Verifying the result they were looking for, I suggested doing trial runs using an ITW Dynatec BF Applicator.  Not only did the applicator work much better, but we were able to retrofit it to work on their current Nordson machines.  The results were as expected, and their ongoing problem came to an end.

Due to our solutions and constant support, HAR's relationship with this manufacturer has grown tremendously.  Over time, they decided to replace their old Nordson hot melt machines one by one with ITW Dynatec products. 

If you have an adhesive or adhesive equipment related problem that hasn’t been solved, give us a call.  We would love the opportunity to help you find a solution.

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.
