One of the biggest threats to the efficiency and profitability of any production line is unscheduled machine downtime. It can be a sudden production halt, or an intentional machine stop by an operator who has detected defective functioning on the line.

Electric Save Time,Money Blog Post_Image 1

Not only does this cause time loss, but also results in increased over-time to meet production goals, as well as replacing a small part that might be currently out of stock. Such unscheduled machine downtime forces operators to leave their tasks and try to fix the problem, which sometimes requires specific knowledge and can only be fixed by the technical service of your packaging machinery supplier (who, to make matters worse, is located miles away and unable to provide immediate assistance). Simply put: it costs you time and money. Sometimes lots of money.

As a leading manufacturer of adhesive dispensing systems for the packaging industry, we are aware of how distressing this situation can be for our customers. For that reason, we have decided to focus on exactly why a hot melt glue system could cause a packaging line to stop.

We found that the main reason for failure on a hot melt glue gun was typically compressed air.  Luckily, we also identified a solution to fix this problem: electric hot melt glue guns. To dive deeper, in this post, we examine how all-electric hot-melt systems save more time and money than pneumatic hot-melt dispensing machinery by looking closely at long-term issues reported on air quality, solenoid performance, spare parts replacement and adhesive usage.

Air Quality:

How can compressed air have such a big impact on the life and performance of a hot melt applicator? To start off, manufacturing compressed air is expensive, and due to the age of most systems, the quality of the air starts diminishing shortly after installation. This in turn affects the efficiency of the applicator, the accuracy of the pattern and the potential lifespan of the hot melt system. On the other hand, an all-electric valve has a consistent performance throughout its entire life, which can reach up to 300 million cycles.

Solenoid Performance:

Pneumatic hot melt glue guns require air solenoids to activate the module. The combination of heat, debris, oil and air moisture quickly weakens the solenoid performance, resulting in sloppy or inconsistent glue patterns, spitting, or no glue firing at all. While you might think replacing the solenoid would correct the issue, more often than not, it’s hard to tell whether the origin of the problem is the air-activated solenoid valve alone. Therefore, the nozzle, module and the solenoid are all replaced to ensure the problem is resolved, which necessitates an important investment in spare parts, inventory, storage and technical training. Since electric valves don’t require solenoid valves, these associated issues are of no concern.

Spare Parts Replacement:

Seals and moving parts in the valve are subject to wearing out and require regular maintenance and replacement to maintain the valve in good condition. By reducing the number of seals, not only can you diminish the maintenance requirements, but also dramatically reduce chances of failure. Such is the case with an electric valve, which uses a small number of seals and other moving parts, guaranteeing longer life with less maintenance. To help illustrate this point further, we’ve created this infographic comparing the number of seals in both hot-melt systems.

Adhesive Usage:

Last but not least, electric valves reduce adhesive usage up to 75% while continuing to provide perfect bonding and sealing.

Compared to pneumatic hot melt glue guns, an electric valve can be set to work on stitch mode, producing any desired pattern larger than 1/8” (3 mm). The size of the bead and the distance between beads can easily be set and controlled from a Pattern Controller, which is usually provided as an integrated feature of the hot melt unit. All of this translates to great savings, while still allowing you to deliver a more eco-conscious product.

Inserting and product attachment are a vital part of Print Finishing. Every day we see mailers with gift cards, credit cards, gas cards, and more. Whether your company is sending out a promotional flyer or attaching a card, coupon or mailer, using an efficient, cost-effective adhesive applicator is an important condition. Obligations to produce excellent print quality, complex folds, special perforations, and the need for speed are growing. It is critical to your brand reputation that this product maintains its integrity even after reaching the end-user. Furthermore, with today’s competitive landscape, producing these materials with a consciousness for sustainability is a requirement.  In our line of business, that means using less adhesive and producing less waste. Here are five ways one hot melt gun can start lowering your adhesive usage today.

1.“Opt-In” on Options. One of the most critical aspects of adhesive application on a mailer or graphic is the ability to customize the adhesive pattern, so that the system can maintain the flexibility it needs for each customer’s specific requests. Because accuracy and precision are a necessity, it is critical to administer an adhesive application that meets these standards. In a market that is constantly reinventing itself, whether you need micro beads, large beads, are folding or perforating the mailer, or need 30 beads versus 15 beads, the electric valve that provides you with the ability to select an option from a limitless number of bead sizes and pattern lengths is the way to go. Valco Melton’s Ecostitch™ Valve is one of the only valves to provide these options to its customers.

2. Eliminate Stringing.  Another critical aspect to applying a perfect and efficient adhesive pattern on mailers and graphics is the ability to eliminate stringing and provide a clean cut-off. In other words, when the mailer arrives at the end user, it is important that they can open the seal without tearing, ripping, or damaging the mailer. If the end-user tears or damages the mailer that is associated with your company name, it can affect what they think about the quality of your brand.

3. Ensure the Dispensing Valve is Multi-Use. Many mailers are glued with permanent, fugitive, and pressure sensitive adhesive. It is important to have an adhesive applicator that can work with nearly any adhesive to provide the clean finish and quality application you are looking for.

4.  Utilize the “Zipper Stitch. Valco Melton’s Ecostitch™ adhesive applicator applies adhesive in what they have started to call a “Zipper Stitch™.” This adhesive pattern type is truly unique and far superior to the traditional adhesive application method used on mailers. Traditionally, manufacturers would apply a long line or series of lines of adhesive to seal the end piece. More specifically, a large bead of glue is applied to the surface and spread out across the sealing area, which causes the end user to bend, fold, and tear the mailer when opening the seal. The Zipper Stitch is a superior pattern because it provides a perfect, uniform seal across the sealing area. Instead of a thick bead of adhesive stretched across the surface, there is a series of micro beads applied across the surface to provide a seal that can withstand any quality control test. Simultaneously, this allows the “at home” user to open and re-seal the mailer without tearing it. The Zipper Stitch provides a clean opening, while eliminating any tearing or other damage. This increases the integrity of the mailer, which in turn gives the end user a more positive experience.

5.  Long Lives the Clean Valve! With speed and ceramic materials, electric valves are able to produce a tight closure that pushes out and pulverizes any char or debris that comes through the valve. Essentially, the valve cleans itself. By using a top-down adhesive path and electromagnetic coil, low pressure and large orifice size, the valve is able to virtually eliminate nozzle plugging. Additional features support easy change-outs and variable valve configurations with options like a “quick-connect” coil.

As an example of how powerful a little adhesive valve of this kind can really be, Valco Melton’s Ecostitch™ adhesive applicator is built with a ceramic seat and carbide-tipped plunger.  It easily reaches 3000 cycles per minute continuous duty with a lifetime of up to 300,000,000 cycles. This solution has produced every case I’ve seen with instant ROI– Payback has occured in as little as four months.

By selecting a Hot Melt Adhesive Applicator that can achieve these 5 things, your adhesive can be reduced by up to 75%.  Don’t believe me? Check out this case study.

We have been selling and manufacturing adhesive dispensing equipment and cold glue or hot melt systems of all kinds since 1952. Through careful testing and repeated implementation around the world, we have experienced firsthand, why various systems outperform others.  In our lastest post, we concluded that up to 75% of adhesive can be saved by implementing an all-electric hot melt glue system. Just to get the point across, this week we have uncovered 7 additional ways that an all electric hot melt glue system is reshaping the packaging machinery, folding carton, and print finishing industries.

#1 – Fewer Plugged Nozzles:

Did you know that by using an all electric system, you can use lower pressures to administer the adhesive from the hot melt glue gun? Well you can! This means that the nozzle diameter can be increased. The larger the nozzle, the lower there is a chance for clogging. Maintenance requirements and any risk of downtime are virtually eliminated.

#2 – Safer Operation:

As you probably know, the high pressure required to operate a pneumatic system along with the high temperatures of the hot melt adhesive, is a potential safety hazard. Fortunately, there is a better way… Because an all-electric system utilizes a gear pump, they are able to provide operators with a safer dispensing application and work environment.

#3 – Less Chances of Failure:

Electric gear pumps and electric valves utilize almost 90% less seals and additional parts required to run pneumatic pumps and valves. This practically eliminates the chance of failure caused by worn out or imperfect seals.

#4 – Any Pattern Configuration:

Electric hot melt glue systems can be easily configured to work on stitch mode through a pattern control to produce any pattern larger than 1/8” in length (3mm), with exact start and stop placement and virtually without stringing. Pattern size is not affected by pumping rate limitations as often occurs with pneumatic systems.

#5 – Longer Valve Life:

By using electric hot melt glue guns, the lifespan of a valve module can reach up to 300 million cycles with slight variations, depending on the type of adhesive used. What that means for the user is easy savings and less hassle.

#6 – Reduced Maintenance:

The most frequent downtime on packaging machinery involves changing failed pneumatic glue modules, plugged nozzles and solenoids. Switching to electric guns eliminates the need for gun solenoids and modules that can be soiled and worn with a dirty, wet, and sometimes inconsistent air supply. In result, maintenance requirements are reduced to a minimum level.

dollar sign icon#7 – Minimal Spare Parts Stock:

With fewer moving parts virtually eliminating the chances of failure, the spare parts stock is reduced to a minimum, resulting in lower investment, storage costs and downtime associated with the replacement of parts.

To better understand how these 7 aspects affect your overall revenue and other key factors, we have put together a visual example with an intuitive diagram. You can get this complimentary download instantly here.

Manufacturers have been using compressed air systems for many years. In fact, most adhesive dispensing systems today use pneumatics simply because air has always been available and this was the original design criteria in the development of hot melt system gun technology. Although pneumatic systems will get the job done, there are several known, long-term issues associated with compressed air:

1. Constant and costly replacement of parts gone bad.

2. Diminishing solenoid performance.

3. Pneumatic guns plus solenoid have eleven dynamic seals per set compared to electric guns that have no dynamic seals.

It’s a fact; Pneumatic valve performance starts diminishing shortly after installation. Most modules are replaced because they won’t fire glue, not because they are leaking from the glue seal. This is because the pneumatic portion of the valve module has failed, not because the fluid seal failed. Compressed air is the cause. Many nozzles are replaced because there is no glue coming from the module. Although nozzles do sometimes get plugged, there are just as many issues with the module or air solenoid not performing at full capacity that give the impression that the nozzle is the cause. The nozzles, module and air activation solenoid are all replaced to be sure the problem is resolved.

Air activation solenoids, like valve modules, are constantly pushing air through them. The combination of heat, debris, oil, and moisture in the air will cause the solenoid performance to start diminishing very quickly. A solenoid can still open and close, but it might only be working at 40% of its full capability. This means the volume of air going through the air solenoid is most likely much less than what is shown on the regulator. The symptoms of this issue are sloppy glue patterns, spitting, inconsistent glue patterns and in some cases, no glue at all.

Manufacturing compressed air is expensive and because of the age of most systems, the quality of the air diminishes each year. Compressed air contains debris that enters the piston pump, air solenoids, and glue module with each activation. This problem can be completely avoided by using an all-electric hot melt system. The all-electric hot melt system removes this contamination, resulting in a higher quality and much cleaner product. An all-electric system does not have dynamic seals in the valves, contains a built-in troubleshooting guide, built-in gun filter, and there are no solenoids required. All of these prevent the constant replacement of system parts and diminishing performance; two issues that are common in pneumatic systems.

All-electric systems not only provide a higher quality product, but also decrease downtime caused by diminishing system parts, which simultaneously increases production. Whether you are a folding carton, packaging, or print-finishing manufacturer, all-electric adhesive systems can improve your production rates and increase the quality of your product.

We tested our CHOICE all-electric system over a three-week period with one of our customers that was using a pneumatic valve and a traditional bead of adhesive for their card attaching applications. The customer provided us with sample product of card attachment that was completed with their pneumatic system. Our goal was to run this exact same card attaching application with our all-electric system for three weeks to show the customer the adhesive consumption savings and cost savings they would achieve by using our CHOICE system compared to their previous method.

First, we weighed ten of the products glued with the traditional, pneumatic valve as well as ten products glued with our all-electric system. After obtaining the weight of the glued cards, we subtracted the card weight (6.29 grams) to determine the weight of the adhesive applied to each card. The results determined that there is a 60% reduction in adhesive usage when using the all-electric system compared to the pneumatic system.

We went a step further to discover the financial savings they could attain if 8,000,000 pieces were produced. Now that we had determined the weight of the adhesive applied to each card for the two systems, we calculated how many pounds of adhesive would be used with 8,000,000 pieces of product by the pneumatic system (3,227.57 lbs) versus the all-electric system (1,287.50 lbs).

Using a hypothetical price of $3.00 per pound of adhesive we were able to determine the adhesive cost for the pneumatic system at $9,682.71 and the adhesive cost of the all-electric system at $3,862.50. Bottom line, the customer saves $5,820.21 using the all-electric system.

The test clearly showed the customer that the all-electric system lowers adhesive consumption by 75%, which in turn lowers the adhesive cost. The new systems paid for themselves in less than 4 months.

The great news is that Valco Melton’s CHOICE system can be implemented onto any existing line, but moreover the amount of investment you make today will be in direct correlation with the return you will see tomorrow.

transparent labeling

Businesses have been using labels to identify and ship their product since the late 1800’s. Label making has advanced from the art of lithography to being able to print self-adhesive labels in the comfort of one’s own home. Today, the demand for label stock is higher than ever and many label converters do not own a coating station. Instead, they are buying their label stock pre-coated. What those people have not yet discovered is that there are three significant advantages to having their own coating station for label converting worth looking into.

The first and most important advantage is savings. Switching from pre-coated label stock to a coating station is much more cost-effective. The converter can mount the coating station to their press,coat their own pressure-sensitive label stock in-line, and now have control over the cost of their raw materials. This allows the converter to increase their margins on existing products.

The second advantage of a coating station is that it gives the user the optionto perform multiple adhesive applications. Various coating widths and patterns are available with easily adjustable coating heads and interchangeable blades. A coating station offers an extensive range of accessories providing flexibility to the project.

Last but certainly not least, the third advantage of a coating station is reliability and consistency.  When the converter is in control of the coating process on their label stock, they can breath easy knowing that the coating station will provide continuous and reliable adhesive application for each project. Whether you are using hot melt adhesive application or cold glue, coating stations ensure consistency with each application.
Aside from bringing significant advantages to your production process, coating stations are easy to install and fully compatible with existing machinery.

Having worked in supplying adhesive dispensing equipment and packaging machinery to people all over the world since 1952, we have heard quite a few horror stories from customers using hot melt glue systems. They mostly stem from the same common mistakes. Unfortunately for them, if they had known what we are about to tell you, these issues could have been easily avoided and the risk of downtime dramatically reduced.  In an effort to make sure you don’t become another one of the characters in these legendary stories, we suggest following these 5 easy tips: 

  1. Never start the unit before it has reached working temperature.  We know time is money and waiting for the system to reach working temperature everyday can feel
    image of hot melt pattern control system
    hot melt pattern control system

    like you are wasting valuable minutes that should be spent doing other things. However, it is necessary for the unit to reach working temperature to ensure that the adhesive has the required viscosity. Failing to do this can create problems with the pump and other internal parts that will result in unstable working conditions and downtime. So, count this daily ritual in as an important one.

  2. Stop “overfilling”. When the hot melt glue system runs out of adhesive, it can make the entire packaging line come to a screeching halt, resulting in expensive downtime. Although overfilling the melter to ensure the adhesive supply will last longer seems like it could be a brilliant idea, once the adhesive is actually melted, it can result in unwanted spillages. This can create serious safety hazards for yourself or other operators, as well as damage your packaging equipment.
  3. Get rid of risky maintenance practices. Regular maintenance processes should always include cleaning your hot melt glue systems. Rushing through this task can sometimes lead operators into manipulating the melter without getting rid of the high pressure first. Given the risk that the combination of hot adhesive and high pressure involves, eliminating the pressure from the system is a necessity to ensure a safe cleaning process.
  4. There is no universal configuration. Although it would be ideal, unfortunately, one configuration does not work for all applications. It is important to know the exact parameters, such as line speed, pattern type or applicator cycle speed that each application requires to avoid defective bonding or stringing caused by either an excess or a lack of hot melt adhesive.
  5. image of valcomeltons high-speed EcoStitch Applicator
    High-speed EcoStitch Applicator.

    Always use the adequate type of adhesive. It is important to be aware of the type of adhesive your application needs. Take into account the product that is being sealed and the hot melt glue system being used. Using the wrong type of hot melt for your products may create defective bonding or even damage the material. If the adhesive is not suitable for the hot melt glue system, common problems can include an unstable pumping rate due to incorrect viscosity, clogged nozzles due to debris formed by burnt adhesive, or a complete stop of the system if the melting requirements are higher than the system’s melting rate. If you are not sure, ask!  There is nothing more glorious than a perfectly glued product.

Tray Forming in Packaging Machinery
Tray Forming

I often hear colleagues discussing their take on various adhesive related topics.  Most recently, the conversation was about hot melt glue systems vs. tape systems in the packaging industry. I questioned whether one system was truly more beneficial than the other or if it was just the right choice for a few specific groups.  And if not, why not? In formulating an opinion, I thought whom better to ask than my colleagues who are specialized in both? From a cumulative response, a pattern was discovered. I noticed a set of 5 differences. I have listed them here with the hope that this might also benefit you when trying to decide which system is right for you.

1)    Consumption: If you have sustainability requirements, its important to consider how much glue is being used. A hot melt system applies less adhesive with the ability to provide a shorter glue line. Small amounts are used on the minor flaps as compared to a roll that uses more glue.

The tape roll is replaced once it reaches its end, but before the entire tape roll can be used.  Most companies that tape will replace the roll that is not finished during changeover.  This can cause up to 10% waste. No replacement is needed with hot melt. In addition to this, about three inches past the end on both sides in necessary to provide the strength needed.  Which leads me to our next point…

2)    Strength:  Strength is important in most situations. Broken bonds can result in product jams on the line. Once the shipment makes it out for delivery, a deeper strength is sometimes required for adverse weather or wear-and-tear caused by moving and re-use.  Hot melt not only burns into the microfibers of the box, but also continues to burn several minutes past the compression section of the parent machine. Product tape does not gain additional strength after application.

A glued box is more secure after glue has been applied and transformed from liquid to solid. The box will remain sealed until the product has reached the end user. If using tape, cutting the tape can easily open the box. To re-seal, new tape must be applied.

Box Closing with a Dispensing System
Box Closing with a Dispensing System

How do you know what type of strength you need? Well, subsequent drop tests show that boxes sealed with hot-melt outperform those with tape.  The deeper bond is necessary if you believe you need additional security with the possibility of a dropped box.

3)    Price: I am confident that most of you are looking to find the best deal.  Unfortunately, one place that tape and hot-melt systems are alike is in their fluctuation of price off-set by the cost of raw materials. However, in order to produce tape, a large and expensive coating system is required to apply costly pressure sensitive adhesive to the product. This is an additional step in the process adding additional cost to the customer. Once adhesive is manufactured, it is shipped in a number of sizes, from 25-pound boxes to 250-pound totes; all of which have an effect on the price of adhesive.

Packaging companies that use corrugated boxes can use a less expensive adhesive (EVA) to lower cost. Hot melt equipment has the ability to control the amount of adhesive used through several different methods: pattern placementpattern length, and stitching the same length (up to a 50% reduction).

The actual adhesive for a hot-melt system costs somewhere between $2.50 and $3.50/lbs.  Tape is about $8-$10 a roll.

4)    Safety: When it comes to safety, as with most machinery equipment, both hot-melt and tape systems involve some risk.  Hot melt is usually installed inside a secure machine that you cannot operate while the doors are open. If touched improperly, there is a risk of burn. However, there are a number of systems available with safety features available to prevent this from happening.  One example is a locking lid feature. This inhibits the user from coming in contact with the unit during operation to prevent any potential burn. Another feature, as seen on Valco Melton’s new EC Series Melter, forces the unit to lose pressure if the doors are open. On the other hand, tape machines’ cutting blades can be dangerous. During operation and when changing out the roll, the cutting blade is exposed offering little protection to operators.

5)   Maintenance Cost: For both tape machines and hot melt equipment, the maintenance is about the same. Each has moving parts that may fail. Standard preventative maintenance is also necessary for both.  Knowing this, it’s important to compare the potential cost of maintenance care. Hot melt equipment has a larger upfront cost ranging from 5-10k for a new line with 5-7 year life. New, high-end tape machines can cost around the same. Others will cost less overall if you use the same machine more than 10 years. Hot-melt parts are changed out more often than tape seal equipment. However, the cost of these parts can be recovered if you can focus on using less glue to provide a superior bond.
