Davis-Standard Announces First Quarter R&D Additions

 

 

The Davis-Standard Technical Center has announced two exciting additions to its lab capabilities in Pawcatuck, Conn. By the end of the first quarter, Davis-Standard will offer trials for its Davis-Standard Helibar® groove feed extruder and the DS Activ-Check control system for continuous extruder monitoring. According to John Christiano, Davis-Standard’s Vice President of Extrusion Technology, both present new opportunities for customers to improve and strengthen processes.

“These technologies have been proven in the field and we’re pleased to offer experimentation in our technical center,” said Christiano. “We are firm believers in partnering with customers to make processes better and in maximizing their capital investments. I am eager for customers to use both the Helibar and DS Activ-Check in establishing performance baselines during real-world trials.”

The Helibar extruder is the next generation in Davis-Standard’s groove feed extruder offering. The dimensions of the extruder in the lab will be 65mm with a 36:1 L/D. With the Helibar design, helical grooves inside the barrel run along the entire barrel bore. This technology has shown to increase extruder output rates while improving energy efficiency and reducing barrel and screw wear. Other advantages include lower start-up costs, shorter residence time and the ability to process higher levels of regrind. Christiano noted this is especially beneficial for high-profile applications where speed, melt quality and efficiency are paramount.

The DS Activ-Check system will be mounted on a 4.5-inch (114mm) extruder. Using a continuous monitoring platform, the DS Activ-Check strengthens preventative and predictive maintenance for extruder operation. Operators are able to monitor key mechanical and electrical components of the extruder and gearbox and receive early notification of potential component failure to prevent unscheduled downtime. Users can obtain notifications via e-mail and text, and can remotely monitor conditions via smart devices or remote PCs. Users also benefit from the collection of operational data, leading to significant cost-cutting opportunities.

John Clemens, Davis-Standard’s Director of Extrusion Controls, added, “The capability to monitor extrusion line variables such as mechanical and electrical system conditions is essential in order to bring products to market faster. I look forward to customers having the opportunity to test the many advantages of this system for both extrusion and converting processes.”

Both technologies will be available to customers by the end of the first quarter. If interested in scheduling a trial, please contact marketing@davis-standard.com.

Davis-Standard Teams Up with Industry Leaders for MD&M West Exhibit

Running FEP Line to Showcase Best-in-Class Technology

The technologies of Davis-Standard, Conair, Zumbach and other industry-leading companies will be on display with a running FEP line at MD&M West in Anaheim, Calif., February 5-7, 2019 at booth 3839. The coextrusion line will be processing FEP medical tubing with three barium sulfite stripes. The line will be equipped with two of Davis-Standard’s MEDD (Medical Extruder Direct Drive) extruders along with Conair MedLineTM upstream and downstream equipment, Zumbach gauging, Guill die tooling and resins supplied by Daikin and PolyOne Colorant Chromatics. MD&M is the largest medical technology show in North America, making this the ideal venue to demonstrate Davis-Standard’s medical tubing capabilities alongside industry partners.

According to Dr. Jason Baird, senior process engineer at Davis-Standard, this line demonstrates the value of long-term collaboration to meet the functional and versatile tubing demanded by the medical industry. “The tubing at the show will feature three stripes and will represent the latest technology required for processing barium sulfite products,” he said. “One of the greatest advantages of this line is that it gives the processor the option to lay the stripes on the outside of the tubing or embed them within the tubing wall. Every component is engineered for tight tolerances, highquality and output efficiency.”

 

 

Specific to Davis-Standard, the MEDD extruders will demonstrate the value of an extruder designed specifically for medical environments. The MEDD enables processors to easily swap barrels and/or feedsection liners to change extruder diameter and/or length while keeping alignment intact, providing versatility in cleanroom settings where space is limited. The extruder’s direct drive design eliminates the need for gearcase oils and belts that create particulates, and the machine is mounted on linear rails to make seamless adjustments with or without a melt pump. At the MD&M show, both extruders will have ¾-inch (19mm) diameter barrels with L/D’s of 24:1 and 16:1. In order to limit exposure of the radio-opaque barium sulfate filler to the high temperatures of fluoropolymer processing, a shorter 16:1 extruder along with special screw design will be used. All components of the tubing line will be monitored and controlled by Davis-Standard’s eVUE control system.

According to Kevin Dipollino, Davis-Standard’s product manager of pipe, profile and tubing, “This line represents an all-encompassing package in both design and processing technology. It shows the value of complementary components among reputable industry partners in creating an end-to-end solution that addresses a growing segment within the medical tubing marketplace.”

Davis-Standard R&D Pioneer Norton C. Wheeler, Jr. Dies at 96

Norton C. Wheeler, Jr., one of Davis-Standard’s most beloved and accomplished technology innovators passed away the end of September at his home in Mystic, Conn. He was 96. Wheeler’s distinguished career at Davis-Standard spanned six decades. Even after his retirement in 1989, he remained engaged as a consultant until the age of 90. He is known as the father of the DSB® (Davis-Standard Barrier) feedscrew, authored numerous technical papers, and mentored many Davis-Standard engineers. His list of contributions to Davis-Standard and the plastics industry, in general, is extensive. He was awarded Fellow of the Society of Plastics Engineers in 1985 and received the Bruce C. Maddock Award in 1998 for his pioneering work in research and development.

“I was honored to know Norton and work alongside him for so many years. He was a great mind, problem-solver and infinite resource. He was also a wonderful human being, always willing to give of himself in his modest way,” said John Christiano, Davis-Standard’s Vice President of Extrusion Technology. “Our R&D capabilities and technical leadership began with Norton and he remained so vital to our work throughout his life. His achievements not only defined Davis-Standard as an R&D leader, but they changed the industry. He was truly one of a kind and will be dearly missed.”

Being part of Davis-Standard was in Wheeler’s blood. His grandfather, Charles E. Wheeler, was an original owner of Davis-Standard, purchasing the business as the Standard Machinery Company in 1904. His father Norton Sr. and his uncle John were instrumental in assisting their father with modernizing and diversifying the operation. Under the leadership of Wheeler’s father, company president in the 1940s, and his new partner Benjamin Davis, the company transitioned from a manufacturer of compression molding presses before and during World War II into a post-war manufacturer of extrusion machinery. The company became Davis-Standard in 1948.

Wheeler joined Davis-Standard in 1951 after serving in the U.S. Air Force and graduating from Brown University with a chemistry degree. Wheeler was a natural in the research environment. He spearheaded Davis-Standard’s first lab in the 1960s, growing the facility from a small space to a building equipped for customer trials and extensive R&D within a decade. During the following 20 years, he conducted revolutionary research with regard to feedscrew design and extrusion process control. Of all of his achievements, Wheeler was most proud of the fact that Davis-Standard was the first company to fully instrument an extruder with multiple pressure transducers.

In the early 1980s, Wheeler patented the well-known DSB screw design. This design overcame limitations of existing barrier screws by optimizing the screw’s melt region, leading to improved stability and performance. The DSB quickly became the industry’s premier feedscrew and gave Davis-Standard a global technical presence. It also helped the company expand into multiple processing areas such as pipe and profile and sheet. The DSB continues to be the basis for all Davis-Standard screw designs.

Wheeler was predeceased by his wife of 69 years, Mary Anderson Wheeler, and is survived by their five children, six grandchildren and eight great-grandchildren.

Davis-Standard Invests $2 Million to Expand Feedscrew Manufacturing Capacity

To support ongoing growth in feedscrew manufacturing, Davis-Standard is installing its fourth CNC machining center at its facility in Pawcatuck, Connecticut. The $2 million investment will further boost production efficiency and will enable Davis-Standard to increase feedscrew production by over 25 percent. The machining center is expected to be operational by mid-October.    

“This investment reflects our continued commitment to best practices in manufacturing and in supporting customers with best-in-class feedscrew technology,” said Mike Newhall, Davis-Standard’s Vice President of Operations. “The CNC machining center being installed is the same brand as our existing machines, Weingartner, which makes software programs and tooling interchangeable. We also have highly skilled machinists already trained to run this type of equipment. This will further add to our ability to meet customer demand and improve our overall responsiveness to our customer’s requirements.”

The additional center is a Weingartner Pickup 700 Whirler, capable of machining feedscrew sizes that comprise 80 percent of Davis-Standard’s screw volume. This includes feedscrews from 1.5 inches (38mm) to 6 inches (152mm) in diameter and in lengths up to 207 inches (5,200mm). The machine will augment existing capabilities in Davis-Standard’s feedscrew operation, which currently manufactures over 1,000 feedscrews annually. It will also support feedscrew cycle time reduction, enabling the company to improve delivery times and maintain a steady stock of feedscrews in various sizes and finishes.

How flexible packaging trends are shifting and why

By Lisa McTigue Pierce in Flexible Packaging on August 29, 2018

Technological innovation, sustainability concerns and attractive economics are among the reasons for the phenomenal growth of flexible packaging in the last two decades in the U.S. With an estimated $31 billion in sales in 2017, according to the Flexible Packaging Assn., brand owners are embracing films, pouches and bags as a go-to packaging solution, thanks in part to wide acceptance by American consumers.

But we’re also seeing aluminum sourcing concerns because of U.S. tariffs, as well as major competitive moves—reflected, for example, by the recent Amcor acquisition of Bemis.

With flexible packaging so much in the spotlight, Packaging Digest wanted to see what is shifting in the market. So we conducted a virtual roundtable with five industry experts from various areas in the supply chain: resin supplier Nova Chemicals (page 1); printing press maker Comexi (page 2); extrusion/coating equipment company Davis-Standard (page 3); converter Berry Global (page 4); and form-fill-seal machinery manufacturer Pro Mach (page 5).

Their insights show how this dynamic market continues to advance, despite some challenges.

Here are the questions we asked:

1. What top trends are you seeing in flexible packaging and why? What are the drivers?

2. What challenges is the flexible packaging market encountering now and how are they being addressed?

3. Where do you see the biggest growth for flexible packaging moving forward and why?

4. What, if anything, is different about the sustainability message of flexible packaging today versus, say, two or three years ago?

Now, the insights from…

Page 1: Jonathan Quinn, performance films market development manager, Nova Chemicals, a plastics and chemical company that makes resins for flexible packaging.

Page 2: Raúl El-Fakdi, flexo brand manager, Comexi, a family-run manufacturer of flexographic printing, offset printing, gravure printing, laminating and slitting equipment.

Jonathan Quinn, performance films market development manager, Nova Chemicals, a plastics and chemical company that makes resins for flexible packaging.

 

What top trends are you seeing in flexible packaging and why? What are the drivers?

Quinn: From an economic perspective, trends like consolidation—such as Amcor’s announcement to acquire Bemis—clearly will continue, and we also will see some further uncertainty related to the trade war. Regardless, we believe that packaging trends in the North American market place are driven by the consumer. And three major consumer trends are sustainability, convenience and ecommerce.

1. Sustainability: Shifting demographics and consumer preferences are driving the demand for more sustainable solutions, in packaging and far beyond. Negative publicity around ocean gyres and plastic-filled beaches only add to the urgency to increase recyclability, curbside collection, sorting capabilities and finally innovation to increase demand for recyclable materials. Rigid-to-flexible conversion, with its huge sustainability benefits, has been a trend for some time now. Add to all of these the opportunities resulting from more cost-effective and technologically feasible recyclable packaging solutions available today, and sustainability is at the top of everyone’s list.

We are at a unique point in the history of flexible packaging. According to the New Plastics Economy, major brand owners and retailers—including Danone, Mars, PepsiCo and Coca-Cola, and Walmart—are working towards goals around all reusable, recyclable or compostable packaging, and these initiatives are speeding the shift to recyclable flexible packaging.

There is also a significant push by flexible packaging companies for sustainable packaging today. All in all, we’re seeing a critical mass of players moving the needle, after many years of talking about the need for action.

2. Convenience, convenience, convenience! The consumer of today is very different than that of the traditional consumer 20 years ago. The younger generations’ typical lifestyle is busier and busier, and at the same time, they’re looking for healthier options—that often require performance packaging. Everyone is on the go and these buyers want the products they consume to be delivered quickly, consumed easily and disposed of efficiently.

3. Ecommerce: Ecommerce is a game-changing example of the convenience trend. Its efficiencies, coupled with the ease of comparison shopping, are also driving down prices in many sectors. As Business Insider reports, ecommerce is driving virtually all retail growth, and its impact on flexible packaging will grow with it.

According to FMI, the online grocery market alone may reach $100 billion by 2022. Better performing flexible packaging solutions—especially seal integrity and abuse resistance so products arrive at the consumer’s door intact—will be a must to support the more rigorous ecommerce supply chain.

 

What challenges is the flexible packaging market encountering now and how are they being addressed?

Quinn: We see three challenges, as well.

1. Speed of transformative change: The biggest challenge we see moving forward is innovating at the rate of speed required to keep up with rapidly evolving business models. The meal kits delivery business is a great example. In 2018, we are going to get a good idea if this market segment is going to sink or swim. A key driver for it to survive and thrive will be packaging performing at the highest levels, providing consumer confidence that every week their food will arrive fresh and safe to consume. The “safe to consume” aspect will be that the products be efficiently packaged in well insulated secondary package. In addition, meal kit customers feel the amount of packaging is excessive and non-recyclable, according to a Packaged Facts report, so primary and secondary packaging will also have to have a sustainable format.

2. Consumer perception of plastics: Anti-plastics sentiment continues to rise, both in absolute numbers and relative to perceptions of alternative materials. Consumers are being exposed to media and publications showcasing the negative aspects of one-time-use plastics. Municipal bag bans are cropping up and companies like McDonald’s are discontinuing the use of styrenics, among other moves across the globe.

Our industry can and must do a better job of helping consumers see the benefits of plastics in the context of the total lifecycle environmental footprint. We need to go even further, and help to develop the circular economy, which today is just starting to take shape.

3. Personalizing the consumer experience: Everything from Coke bottles and cans to candy bars are being marketed as a unique experience for each and every consumer. This trend started in the digital realm and now younger consumers especially expect it with their goods as well. As a result, companies are being forced to find new ways to connect with consumers and give them an individualized experience. The challenge lies both in increased costs to deliver on this experience, and the enormous logistical challenges in implementation.

 

Where do you see the biggest growth for flexible packaging moving forward and why?

Quinn: The big trends noted above are the main drivers of growth in flexible packaging. Here’s why…

Sustainability: A lot of growth in flexible packaging is about conversion that improves sustainability. The first wave was in rigid to flexible, which continues to grow the flexible market tremendously while reducing total lifecycle environmental impact as noted above. The next wave is the move to mono-material and other recyclable film structures, whether from non-recyclable multi-material construction or leapfrog conversions from alternative materials. We see the advent of recyclable performance packaging accelerating the growth of flexible packaging tremendously.

Convenience: Kids have been leading the way in some respects in single serve and on-the-go packaging. Examples include packs of apple slices and carrot sticks, pureed baby food in SUPs with fitments and now squeeze packs of applesauce, or going way back to things like Lunchables. We’re now seeing expansion in products like this marketed to adults. Brands are introducing products like retort oatmeal in a SUP with a fitment, and we’re even starting to see convenience products in the produce aisle. For example, Dole is now offering pineapple and watermelon individually sliced and wrapped in a flow wrap, then collated into a secondary package.

Granola and protein bars really speak to this trend and growth, even though we don’t think of them this way. They’re designed to be the perfect on the go refuel!

3. Ecommerce: We’ll see growth in ecommerce flexible packaging related to application customization. The major drivers—“frustration free” packaging and “ships in own container”—enhance the consumer experience and they’re going to drive flexible into applications where it has not historically been. We’re seeing things like using shrink wrap over a primary packaging box instead of a second box, and products traditionally packaged in clam shells and a secondary shipping box transitioning to an easy-open, abuse-resistant, and tamper-evident pouch or other primary package format.

The sustainability benefits of lighter weight flexible packaging will also come into play in ecommerce. Converting to flexible packaging can reduce material costs, shipping costs and ease logistical challenges. These take cost out of the supply chain for the retailer and the shipper and may in turn lower the retail price for the consumer. Products which needed to be merchandised for the retail environment don’t have the same requirement when sold online, which allows for different package formats and branding.

Ultimately, the result will likely be convergence, where one package format and structure can be used for both brick and mortar and ecommerce sales. These packages will incorporate the performance and aesthetic requirement of both sales channels, and offering an overall cost advantage over multiple stock-keeping units (SKUs) for identical products.

What, if anything, is different about the sustainability message of flexible packaging today versus, say, two or three years ago?

Quinn: We see a couple of different perspectives on this. First is the messaging opportunity to consumers, which often takes center stage. However, communication within the industry is also essential to developing and commercializing more sustainable packaging offerings.

Consumer messaging: Today, sustainability is a true driver of packaging innovation, where just a few short years ago it was just a buzzword. Again, shifting demographics come into play. Younger generations have a less positive perception of plastics, and sustainable packaging is an imperative to appeal to these consumers. Programs like How2Recycle label are helping consumers understand flexible packaging recycling options, and enabling brand owners to showcase package recyclability, educate consumers and ultimately drive up collection rates. Industry associations are also starting to step up with concerted efforts to promote the benefits of plastics over alternative materials, counterbalancing some of the anti-plastics sentiments we all see in the media.

Flexible packaging sustainability messaging is also focused on reducing waste in general. Newer technologies are enabling downgauging and related benefits in flexibles that reduce material consumption and waste. These packages also play a role in reducing food waste by extending shelf life and reducing spoilage from leakers and other package breaches. As a result, the messaging now is around the positive influence flexible packaging has on sustainability in the entire value chain.

In short, the message is changing. Sustainability is driving action and resources for all of us in the broader plastic packaging industry.

Within the industry: Sustainability is both a challenge and an opportunity throughout the value chain. We can’t find optimal solutions in isolation; we are all interdependent and must collaborate to develop the environmentally responsible packaging that consumers and brand owners are demanding. More and more industry players understand the sustainability opportunity today, and they understand that how we talk to each other about it is essential, as it influences how quickly and even whether a lot of innovation happens.

Also, no discussion of the sustainability of flexible plastics would be complete without noting the impact of China’s National Sword initiative. This initiative is increasing the amount of recyclable materials that need to be consumed domestically by a huge percentage. We’re going to have to think differently about how to expand the profitable uses of flexible recyclables to consume those additional materials.

Swan® Products Boosts Rates with Davis-Standard Feedscrew Replacement

A recent feedscrew replacement has boosted rates by more than 33 percent for Davis-Standard customer Swan® Products, LLC. Swan Products, the leading North American manufacturer of water hoses for consumer and industrial markets, installed four new feedscrews on existing Davis-Standard extruders at one of its plants in Canada. From order to installation, the project took about two and a half months, saving the company time and money by providing a cost-efficient means to increase productivity.

“We were able to replace feedscrews on older machines and improve throughput by over 33 percent,” said Jose Rossi, Director of Manufacturing, North America for Swan Products. “We appreciate Davis-Standard’s lab facility at its headquarters in Pawcatuck, Connecticut, which enabled us to prove design concepts alongside feedscrew engineers with hands-on experience. They are very thorough in their management and delivery.”

 

The new high-throughput designs included one 2.5-inch (50mm) and three 4.5-inch (114mm) feedscrews. The trip to Davis-Standard’s lab in Pawcatuck proved valuable since Swan needed capabilities to process both PVC and TPV resins. During the trial, several designs were tested to determine the best options for outputs and stability specific to Swan’s process requirements. According to Jason Baird, the senior process engineer at Davis-Standard who conducted Swan’s trial, working with Rossi at the lab was essential to ensuring desired outcomes without worrying about hypotheticals.

“We have analytical capabilities at the lab that enable us to see what’s going on inside the extruder as we test different feedscrews. When you improve output rates, you also need to confirm stability to achieve uniform product,” explained Baird. “Swan supplies garden hoses to major big box stores, so quality and consistency are essential to their business. We were able to verify both outputs and stability while also evaluating every aspect of performance from melt temperature to torque. This gave Swan the validation they needed to achieve immediate results.”

Davis-Standard offers a complete menu of R&D, feedscrew replacement and rebuilding services. Feedscrews are available in sizes ranging from a 3/4-inch (20mm) to 12 inches (305mm) in diameter and with different L/D options. Feedscrews can be designed for any extruder brand and barrel. In addition to feedscrew replacement, Davis-Standard offers barrel measurement services to ensure dimensional fit and best performance. In most cases, quotes for new feedscrews are available within a day. Lab trials can be scheduled to accommodate customer timelines and processing requirements.
