Adhesives in Door and Window Manufacturing

Adhesives are a vital part of quality construction for all types of doors and windows. HAR offers a full line of adhesives that give door and window manufacturers a world of production options. From all types of polyvinyl acetates, hot melts, urethanes and polyurethanes, HAR can tackle any challenge a manufacturer may face.

Here’s an example: One of the most inventive manufacturing companies came to use to help in the design of a new window. This innovative product does not require the expense and time of structural reframing for installation. Our goal was to find a structural adhesive and adhesive application method to hold the glass in the frame that provides superior strength, impact and durability in all types of environments. Through extensive product testing, the window uses a pressure-sensitive hot melt to bond the glass to window frames made with specifically compounded polymers that inhibit UV degradation. Sized to fit between existing 16" studs, these unique windows can be installed simply and quickly, offering an inexpensive, high performance picture window alternative.

Look to HAR to help find unique alternatives to traditional manufacturing practices. When you need strength, flexibility and excellent adhesion to a variety of substrates such as lumber, plywood, particleboard, glass, metals, fabrics, foam and plastics, we work with you every step of the way to make your manufacturing process and your end product is a success. Contact us today!

Automatic Bulk Adhesive Feed System Provides Benefits to Manufacturers

Here's a really informative article about adhesive feed system from ITW Dynatec. Read more on ITW Dynatec's ADS1 Dynfill and contact us to see how using an automatic adhesive fill system can benefit your company!

 

from Adhesives & Sealants Industry, April 1, 2010
by George Hoff, Business Unit Manager at ITW Dynatec

 

Automatic adhesive fill systems offer many manufacturing benefits, including reduced labor and raw-material costs. In addition, the expanded holding capacity of an adhesive storage container increases operating efficiency and decreases the time between adhesive container refilling. Automatic feed systems also eliminate the need to manually fill adhesive tank hoppers, freeing operators to perform other tasks. When using a bulk feed system such as ITW Dynatec’s ADS1 Dynafill, a removable adhesive wand can be fed directly from large bulk containers supplied by adhesive manufacturers to the hot-melt unit.

The Dynafill system continuously monitors the adhesive levels in hot-melt system hoppers; without the use of bulk-feed systems, operators must constantly monitor hopper levels by manually opening the lid and looking at the current volume. This process introduces many variables into the manufacturing process, such as labor costs to monitor and fill the hopper, failure to fill the hopper, and even the chance of spillage or thermal shock to the adhesive. With an automatic feed system, adhesive levels and temperatures remain steady, providing less risk of char and other degradation. The ADS1 is a closed, positive-pressure system that virtually eliminates contaminants that lead to char and nozzle clogging by reducing adhesives’ exposure to the environment. Thus, fewer replacement parts are required and downtime and maintenance are also reduced.

Purchasing adhesive in larger quantities for a bulk-feed system can mean volume discounting. In addition, the system can reduce power consumption, decrease adhesive degradation and waste, and reduce scrap. A safer work environment is also achieved, as operator exposure to molten adhesive when refilling the equipment’s hopper tank is eliminated. The ADS1 features a positive-pressure, self-contained design that minimizes contamination, resulting in improved performance and reduced equipment downtime.

The ADS1 Dynafill can be installed out of the box with simple plug-and-play components. The unit’s control box is attached to the lid assembly, which eliminates the need for separate mounting and saves time and money. The lid assembly is sized to drop into most hot-melt adhesive hoppers and can easily be moved to other hot-melt units. With 120 or 240 Vac standard electrical configurations, the ADS1 requires little to no wiring.

Using an Automated Filling System

Operating on 20 cfm at 50 psi air pressure when feeding, the Dynafill automatically draws and transfers adhesive to the tank hopper when the level falls to a pre-set minimum. Even low levels of adhesive are drawn through a suction wand immersed in the adhesive bin and delivered under positive-pressure to the tank hopper, ensuring little to no waste. A vibrator installed on the wand keeps the adhesive flowing freely. A capacity sensor immersed in the adhesive tank’s hopper responds to a low level pre-set by transmitting a signal to the DynaFill system to draw adhesive through the wand and deposit it in the hopper. When the hopper reaches the pre-set maximum adhesive level, the sensor discontinues the signal to the system and adhesive transfer is stopped.

The DynaFill system can feed a hot-melt unit from up to 20 feet vertically and up to 100 feet horizontally, accommodating adhesive sizes up to a half-inch slat. The flexibility of locating the ADS1 up to 100 feet away from the hot-melt equipment allows for additional floor space considerations.Other features and benefits include:

  • Reduced power consumption.The ADS1 limits the need to open the hot-melt machine’s reservoir lid during the filling operation, an action normally required during manual feeding of a hot-melt system. Frequently opening the lid allows heat to escape, which then requires the hot-melt system to cycle for additional heating. The ADS1 contains and maintains the heat within the hot-melt system and reduces the need for additional heating cycles.
  • Reduced thermal shock. In a manually fed hot-melt system, the unit can go unattended and the adhesive level can run low within the system. This process is inefficient and leads to wasted energy and heat. When the tank is refilled after running too low, it can shock the hot-melt system into overshooting the need for heat. The ADS1 eliminates the risk of allowing the system to run low; an efficient level is constantly maintained in the hot-melt system.
  • Reduced adhesive waste. The ADS1 provides an enclosed system that virtually eliminates adhesive spills and waste. During manual feeding of a hot-melt system, adhesive is occasionally spilled onto the floor or overflows from the adhesive reservoir. With the ADS1, the adhesive level is properly maintained at all times to eliminate overfill. The metal lid fits securely and prevents adhesive from spilling onto the floor during dispensing.
  • Reduced product waste. Most hot-melt systems have ongoing issues with filter and nozzle clogging, due to contaminants and adhesive char. When nozzles clog, the production line must be stopped and improperly sealed product scrapped. The ADS1’s enclosed system keeps contaminants in the work environment from entering into the hot-melt system. Common contaminants include fiber, paper particulate, and miscellaneous objects such as screws and other work-related materials.
  • Safety. Splash back while filling a hot-melt reservoir is one of the main causes of operator adhesive burns. Since the ADS1 takes the operator out of the process of filling the reservoir, the potential for splash back and burns is reduced. In addition, there is less operator exposure to harmful fumes.
  • Floor space requirements. The ADS1 can accommodate adhesive transfer up to 100 feet away. This allows the system to be positioned in an area that has easy filling and maintenance access. In a manual-filling process, 50 lb. boxes are commonly lifted into place so the operator can scoop adhesive to fill the hot-melt system. In some cases, the operator must use a ladder to reach the hot-melt system for filling. The ADS1 bulk-feed system eliminates the use of adhesive boxes and the need to scoop and climb to fill the hot-melt system. The ADS1 system offers an optional caster base that allows operators to simply move drums to the loading area when they need to be refilled from a bulk container.
  • Cleanliness. In industrial areas, materials that can cause tripping or slipping must be kept off the floor. Since the ADS1 is an enclosed system, it avoids the waste and safety hazard of spilled adhesive onto the floor and work areas around the hot-melt system.

Conclusion

Automatic adhesive fill systems offer several manufacturing benefits, including reduced labor and raw material costs, greater holding capacity, and increased operating efficiency.

Product Protection – It’s All in the Container.

Every day, we take products off the shelves or out of our cupboards and open a box or carton to access what is inside. Have you ever stopped to think about that container? Why was it designed that way, how does it stay together and why is it so gosh darn hard to open? Questions like these do have an answer: it is because companies like ours spend countless hours formulating and producing adhesive products geared toward making that container—no matter what the design, shape or material—hold strong and protect its contents.

Through superior technology, we have developed a full line of water based extrusion glues each designed to handle numerous coatings including foil lined boxes. Through our refining process, we have resolved companies’ issues with clogged nozzles and pop open containers. Because of our hands-on approach to customer support, we are known to find or formulate the best adhesive to meet any production requirement from short-run needs to 24-hour continuous operations. Our adhesives are designed and purposely tested on many different machines to carry with them approvals on a variety of extrusion glue systems.

I welcome the opportunity to talk with you about these types of packaging adhesives and create an adhesive solution that works best for your company.

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.

Blister Packs A Punch in Packaging

Did you open up some toys or tools this past holiday? From toys, tools, medicines and many other small consumer goods, blister packs are a great choice in packaging to show off a product while being both cost-effective and highly secure. Made from a thermoformed or injection molded plastic shell called a “blister,” the plastic is bonded to an adhesive coated paperboard, foil or itself, as in the case of a clamshell enclosure, to form a transparent and tamper-resistant package.

Adhesive Technology | Hot Melt Glue | Hot Melt Adhesive

Because of the bonding process, the benefits of using blister packs are many. This plastic formed package protects against environmental factors like humidity and contamination and the finished package can be hung or displayed in a store while keeping the product in full view for the customer. Blister packs offer high marketability due to having custom designed and printed paperboard called “blister cards” that make products more eye-catching and appealing. Because of the low cost of materials used, blister packs are also an economical choice for large production needs.

The adhesives used in blister packaging are designed for high-speed production and must be flexible, bond rapidly, cure fast and stay transparent. We offer a comprehensive line of water-based adhesives, solvent-based and solventless adhesives for blister packaging, including H.B. Fuller’s Flextra™ which is the industry standard for any flexible packaging needs. These adhesives can be used for film, paper and foil laminating as well as hot melts heat seal coating for lidding and over wrap applications. Wherever strong seals at low temperatures or cold-sealed pressure sensitive are required, these adhesives minimize any variations in production due to humidity and temperature so that they will not warp, shrink, crack or seep.  

By the way, if you got frustrated this holiday with trying to open those tamper-proof blister packs try using a manual can opener.

I welcome the opportunity to talk with you about the possibilities of blister packaging and what adhesives would work best for your production requirements.

The Incredible Gluable Envelope

The envelope manufacturing industry in America, which began approximately 170 years ago, started simply as a folding paper machine that had workers apply adhesive by hand to secure the folds with no closure gum or adhesive for the end-user. Interestingly, the first paper envelopes were created in China over 3,000 years ago used to store and distribute monetary gifts. By the late 1800’s, began the use of pre-gummed envelopes much like we see today. Envelopes since have become the way to send any type of correspondence from personal letters to paying bills to direct mail marketing. Even with the advent of email twenty years ago, envelopes still are an essential part of distributing correspondence.

In an industry that produces over 150 billion envelopes each year, demand for high speed and high quality adhesives to convert paper is crucial. Manufacturers need gum and adhesive formulations that perform on a variety of equipment and paper materials to keep them running efficiently. At the same time, there is an increased need for adhesives that are environmentally sound with reduced VOCs (volatile organic compounds) and offer sustainable solutions that are cost-effective over the long-term.

HAR works closely with envelope converters to formulate and support water-based adhesives that meet these challenges. From side and bottom flap bonding, top flap gumming and window patching, we offer clean-running adhesives and gums that provide warp-free joining in high-speed production. Specifically, we supply synthetic resins and dextrin-based adhesives for wet gumming, latex adhesives for pressure-sensitive gumming, and pressure-sensitive adhesives for seal and peel applications.

For a full range of envelope adhesives that are safe and consistent with the best overall value, we will work with you every step of the way to develop flexible adhesive solutions that meet your production needs. Contact us today to get started.

Adhesive Solutions in Vehicle Assembly

When you think of assembling an automobile or aircraft, you may think of metal fabrication, welding and electrical or mechanical components. Yet, adhesives and sealants play a vital part in virtually every aspect of vehicle assembly. Moreover, adhesives and sealants have revolutionized the way transportation vehicles are being designed and built. Thanks to those innovations, vehicles are safer, stronger and more fuel efficient than their predecessors.

Today, for example, an automobile can contain up to 40 pounds of adhesives for both structural and decorative assembly. Structural adhesives not only have decreased the need for traditional welding by nearly 50%, they are also used in combination with bolting and riveting to seal and prevent loosening. In addition, adhesives are required for many nonstructural applications—from the interior trim seating, flooring and molds to exterior trim such as side molding, ornamentations, lights and mirrors. In fact, about 9% of the total annual adhesive production worldwide is used in vehicle construction.

Manufacturers have saved time and money from switching to laborious and expensive welding and riveting. Adhesives and sealants are lighter yet more structurally sound than the classic joining methods, which also makes them more fuel efficient and safer. Thanks to the strength and durability of adhesives, the amount of fatigue and vibrations has substantially decreased and adhesives act as a kind of buffer to provide better protection for passengers. This is why adhesive bonded automobiles continue to perform better in crash tests.

For today’s vehicles, manufacturers use a range of materials including metals, glass, rubber and plastics. Having to adhere to higher safety and environmental standards more than ever before, adhesive and sealant manufacturers are meeting that demand by continually developing innovative technologies. For example, 3M’s ScotchWeld products provide high bond strength to a variety of substrates. These adhesives are used for battery construction, fuel tanks, bumper assemblies and other previously difficult-to-bond applications. In addition, reactive hot melt adhesives are rapidly becoming the adhesive of choice for sidewall construction due to the quality, speed and long-term dependability.

In a world where maximizing safety and design versatility and minimizing production costs are key, adhesives and sealants truly are the ideal solution for bonding and protecting the diverse combination of materials required in vehicle construction.
