Wittmann Battenfeld Opens Doors to Educate Next Generation of Plastics Workers

At the heart of events like Manufacturing Day is the concept that if skilled trades are being taught in the nation’s classrooms less and less, then manufacturers themselves must pick up the slack. Opening the doors of their factories to welcome communities, educators and students allows them to educate potential future employees and demonstrate the true value of their work as well as the cutting-edge technology and processes that make manufacturing stick in the mind of the next generation of workers as a career of the future rather than a career of the past.

This year’s Manufacturing Day was a great success, and next year’s event will be too, but companies need not wait all the way until October to open their doors ever year. Welcoming the younger generation into your facilities is a good idea at any time throughout the year, and, when done diligently, can leave a lasting impact on communities, educators and the future employees of the company itself.

Wittmann Battenfeld, Inc. became the latest SPI member to do just that, opening the doors of their headquarters in Torrington, Connecticut. to the public earlier this month. Wittmann President David Preusse said that while they expected the event to draw between 60 and 80 attendees, it ended up drawing over 200. That’s because the Open House and Future Careers Event hosted at Wittmann was something of a master class on how companies can successfully plan and execute gatherings such as these at their own facilities. Welcoming in members of the community in a way that’s as beneficial to the company’s future as it is to the attendees doesn’t happen overnight, and it doesn’t happen without employee wide commitment and planning. Wittmann Battenfeld’s event had all of these elements, and ended up being a rousing success because of it.

Attendees, who ranged from middle-school children up through college students, parents, professors and teachers, were all split into groups and each progressed around the factory, visiting nine different stations manned by a Wittmann employee. Guests heard from Preusse, about the background of the company, as well as some information about Wittmann Battenfeld’s products and plastics manufacturing process in general, and various other employees discussed their segments of the company, their careers and the opportunities that exist to work in robotics and plastics technology. They gave demonstrations of Wittman’s machinery in action, and some even let some of the younger attendees try out some parts of the plant’s robot controls.

The employees involved with the event were mostly on the technical side, but Preusse noted that they spoke frequently about the various career opportunities available strictly within Wittmann’s corporate structure. “There are 35 different jobs that people who work for our company have, including sales and accounting and all kinds of other jobs,” he said. “People went to the different stations and learned how we program our robots, micro-molding and material handling, and each person that they came to see introduced themselves and said a bit about their history with the company,” Preusse noted, adding that many Wittmann employees have started in one function and often moved around within the company, which only increased the opportunities available to potential future employees that were in the audience that day.

“You can move around in a company like ours, and they might not have known that,” Preusse said. “We were trying to give them a sense of something they weren’t aware of.”

This is where a great deal of the value of events like Wittmann’s comes from; there are so many things that the younger generation doesn’t know about plastics and doesn’t know about careers in plastics and in manufacturing. Open houses invite them to learn something that they otherwise wouldn’t have about a field that’s growing, innovative and, frankly, pretty cool. The flyer Wittmann used to promote the event played up the last aspect, featuring a dynamic image of a Wittmann-branded robot inviting people to register and learn more about the robotics and automated aspects of the company’s facility. “It’s hard to say we’re having a career fair for material handling and auxiliary products in the plastics industry,” Preusse said, noting that most attendees wouldn’t be excited by technical jargon and industry-specific terms, which is why the flyer focused on robots and plastics instead.

There’s also a public service aspect inherent to events like these as well, Preusse noted. “Some high school are training and schooling [in fields like robotics and engineering] but some of the kids are going to college and finding it difficult to find jobs because they didn’t really get a chance to learn about the allure or the complexity of the plastics manufacturing industry,” he said. “It’s unfortunate that they’re just not really exposed to any of that.”

As beneficial and forward-thinking as it is for a company to host events like these in order to excite a new generation of plastics workers and advocates, in many ways it’s also a generous way to get people thinking about options that they didn’t know were available to them. “The idea was that we wanted to give back to the community,” Preusse said. “People of all ages have the chance to really get a great career out of plastics working for very successful companies with great benefits. We wanted to show them some pretty cool stuff that’s happening in the plastics industry, and host an event so that they could learn about a really cool factory right here in the countryside of Connecticut.”

Tips for Making Your Company’s Open House a Success

  • Divide and Conquer – Dividing things into different stations and functions will help keep the program itself lively and engaging. Getting your employees involved in the process will leave a bigger impact on attendees as they share their own stories and passion for their work.
  • Know Your Audience – It’s important to remember that industry terms that are common on the factory floor are largely unheard of beyond a facility’s walls. Using more relatable, understandable terms in any marketing materials and event announcements will appeal to more attendees. Also if you have a target age group in mind be sure to tailor the message in those materials to the attendees you’re hoping to welcome, like the way Wittmann’s promotional flyer focused on robots to draw in younger folks.
  • Have Additional Resources – Preusse noted that they interviewed some Wittmann employees about their plastics career histories and what they enjoyed most about working in the industry and for their company. These are posted on Wittmann’s website on the jobs page, so that attendees can read more of the stories from the employees they met as they toured the facility, increasing the event’s overall impact.

War College in a Plastic World

By Kim Coghill, SPI Communications Director

While the concept of leading in a volatile, uncertain, complex and ambiguous (VUCA) world has its roots in the U.S. military, the business community has borrowed the successful approach to strategic leadership and applied it to management training across industries.

“In reality, VUCA has never been more relevant, for the military and for business,” Gen. George W. Casey Jr. (Ret.), said in a Fortune magazine article that addresses parallels between his leadership challenges in Bosnia, Kosovo and Iraq, and the current business environment.

Recognizing the value of VUCA leadership training, organizers of the 2014 Equipment & Moldmakers Leadership Summit in October have scheduled a half-day Executive Workshop designed to apply VUCA principles to plastics manufacturing management. The program, “Leading in a VUCA World,” will be taught by international business experts from the world renowned Thunderbird School of Global Management.

“Regardless of an organization’s size and footprint, the workshop is designed to equip attendees with strategies to overcome the challenges and seize the opportunities presented in a global industry,” said Jackie Dalzell, SPI’s director of industry affairs and staff leader for the Equipment & Moldmakers Council.

Leadership thinkers have been turning to lessons learned from the military to create paradigms for surviving and thriving in a turbulent, “permanent whitewater” world where old styles of managing predictability were falling short, Thunderbird professors Paul Kinsinger and Karen Walch said in an article titled, “Living and Leading in a VUCA World.”

Kinsinger and Walch said research shows that the keys to leading in a VUCA world include possessing the knowledge, mindfulness and ability to:

  1. Create a vision and “make sense of the world.” Sense-making is perhaps more important now than at any time in modern history for many companies, as we are not too many years away from the time when the global economy will actually be truly “global,” encompassing every country and in which competitors will be emanating from everywhere.
  2. Understand one’s own and others’ values and intentions. This speaks to having a core ability to know what you want to be and where you want to go at all times, even while being open to multiple ways to get there.
  3. Seek clarity regarding yourself and seek sustainable relationships and solutions. Leading in turbulence demands the ability to utilize all facets of the human mind. Even the most impressive cognitive minds will fall short in the VUCA world — it will take equal parts cognitive, social, emotional, spiritual, and physical intelligence to prevail.
  4. Practice agility, adaptability and buoyancy. This means the responsive and resilient ability to balance adroitly and right yourself to ride out those turbulent forces that cannot be avoided, and to pivot quickly to seize advantage of those that can be harnessed.
  5. Develop and engage social networks. The ability to recognize that the days of the single “great leader” are gone. In the VUCA world, the best leaders are the ones who harness leadership from everyone.

The Executive Workshop scheduled for the Summit is based on strategies developed by the U.S. Army College at the end of the Cold War to address threats that created a VUCA world.  Attendees will learn fundamental principles of a VUCA “antidote” combined with specific strategies resulting from in-depth research on trends impacting the plastics industry. The SPI 2014 Equipment & Moldmakers Leadership Summit is scheduled Sunday, Oct. 26 through Tuesday, Oct. 28, 2014, at Loew’s Ventana Canyon in Tucson, Ariz.

Other highlights of the Summit include a Brand Owner Panel discussing technology needs to support their product innovations, what equipment manufacturers and moldmakers need to know about new and reformulated materials, update on the U.S. manufacturing renaissance and re-shoring initiatives, and much more.  Register today by clicking here, seats are filling up fast!  We look forward to seeing you in Tucson.

Polymers Snap in Response to Light, No Other Power needed

A recently published research paper from the University of Pittsburgh’s Swanson School of Engineering and the Air Force Research Laboratory at Wright-Patterson Air Force Base describes plastics that can “snap” when triggered by light. The light energy is converted into mechanical action with no need for traditional machine components such as switches and power sources.

“I like to compare this action to that of a Venus Fly Trap,” says M. Ravi Shankar, associate professor of engineering at Pitt, whose research focuses on innovative nanomaterials. “The underlying mechanism that allows the Venus Fly Trap to capture prey is slow. But because its internal structure is coupled to use elastic instability, a snapping action occurs, and this delivers the power to shut the trap quickly.

Shankar, collaborating with Timothy J. White of the Air Force Research Laboratory and Matthew Smith, assistant professor of engineering at Hope College (Holland, MI), focused on the elastic instability of azobenzene-functionalized polymers (both amorphous polyamides and liquid crystal polymers) prepared by the Air Force lab, which showed unprecedented actuation rates and output powers. With light from a hand-held laser pointer, the polymers generated high amounts of power that converted the light into mechanical work without any other power source.

“As we look to real-world applications, you could activate a switch simply by shining light on it,” Shankar said. “For example, you could develop soft machines such as stents or other biomedical devices that can be more adaptive and easily controlled. In a more complex mechanism, we could imagine a light-driven robotic or morphing structure, or micro-vehicles that would be more compact because you eliminate the need for an on-board power system. The work potential is built into the polymer itself and is triggered with light.”

Scientists have known for years about a class of photo-responsive polymers that would react to light with no other power source. Problem was, their movement was very slow. The research team shaped the polymer into a geometry resembling a hummingbird’s beak or the trap of a Venus Fly Trap plant. When irradiated with light, the polymer initially deforms slowly, but when it reaches a critical state, it snaps. Shankar told KurzweilAI they generated actuation in millisecond time-scales and power approaching kilowatts per cubic meter at radiation intensities far less than 100 milliwatts per square centimeter and potentially over long distances.

Shankar, White and Smith published their findings in the Proceedings of the National Academy of Sciences in early November. Shankar’s research was enabled through an eight-week Air Force Office of Scientific Research Summer Faculty Fellowship.

High-Tech Plastic Fibers Take On Increasingly Tougher Jobs

The Economist magazine’s Technology Quarterly reports on leading-edge tech from every sector, and the latest issue once again has turned to the plastics industry for its newest and coolest. The editors did not, however, focus on obvious targets such as plastics in airplane or car bodies, micro components or another breakthrough medical device.

As the article “Material benefits” states: “…researchers around the world are now cooking up myriad new textiles capable of containing explosions, protecting astronauts, thwarting bacteria and even keeping buildings standing during earthquakes.” Textiles? Really? Yes, new fabrics and threads, small and even delicate as they may seem, are coming out of the labs to solve big — often very big — problems in a variety of sectors.

For example, when a cargo net securing freight in an airplane breaks during takeoff, the load can shift backwards and  raise the plane’s nose enough to cause a stall. All too often the result has been a fatal crash. As a result, several major airlines recently have begun using cargo netting woven from fibers of ultra-high-molecular-weight polyethylene (UHMWPE), a plastic material much stronger than the polyester netting that has been widely used.

The strength-to-weight ratio of UHMWPE fibers is about 15 times that of steel, according to AmSafe Bridport, a British producer of cargo nets made of Dyneema UHMWPE fibers from the Netherlands-based Royal DSM Group. Though the new nets cost about four times more than the traditional nets, the they last longer and weigh about half as much, and that saves fuel, which reduces CO2 emissions. They also are easier to handle.

The Economist also describes how the Japanese firm Kuraray Group found a way to pump liquid crystal polymer (LCP) through holes 23 microns (millionths of a meter) in diameter to create fibers that are very thin yet incredibly strong. How strong? You can twist about 100,000 of them together to form a cord a bit thicker than a pencil, with which you can suspend about eight tons. Picture four SUVs hanging by that pencil-thin cord.

Branded Vectran, the material also has excellent resistance to stretching. So along with being excellent for applications such as tape and sails, the material can be used for cabling in robots to help keep their gestures precise. On a larger scale, Vectran cabling was used to retrofita pedestrian bridge over interstate highway 610 in Houston, TX — the lightweight, high-strength alternative to steel. The material also performed well in outer space.

NASA’s Pathfinder, Spirit and Opportunity missions successfully landed their Rover vehicles with the aid of airbags made with Vectran LCP fiber. But the larger size of the Mars Curiosity Rover required a new and much more complex landing system.

The Curiosity Rover began its descent from a bit more than a mile above Mars inside an aeroshell traveling about 220 mph. It emerged tethered to a Sky Crane rocket thruster platform that slowed and positioned Curiosity near the surface. Three bridle systems and tethers containing Vectran LCP fiber lowered the Rover 25 feet to a soft landing. (The process is shown in a graphic below.)

The Economist went on to mention several other polymeric textiles used for such non-routine tasks as protecting armored vehicles and keeping buildings from collapsing in earthquakes. However, it did not mention the Dyneema-UHMWPE-fiber cables that held the capsized cruise ship Costa Concordia so it did not slide off its resting place while it was rotated upright last month in a complex 19-hour operation near the Italian island of Giglio. That merits a mention because the ship is more than three football fields long and weighs almost 115,000 tons. Those slender plastic fibers are strong indeed.

Turkish Student, 16, Creates Bioplastic from Banana Peels, Wins Prizes

Elif Bilgin, 16, Istanbul, Turkey

        Elif Bilgin, 16, Istanbul, Turkey

Elif Bilgin is a 16-year-old, tenth-grade student at Koc High School for gifted students in Istanbul, Turkey, and despite her youth it’s fair to say she already merits the title of scientist — award-winning scientist in fact. Bilgin’s ultimately successful two-year search for a way to make bioplastics material from banana peels earned her a place as one of fifteen finalists in the recently concluded 2013 version of the global Google Science Fair. Further, her project won the Voter’s Choice Award and the Science in Action Award sponsored by Scientific American, which gives her a prize of $50,000 and a one-year mentorship program.

Bilgin originally chose to focus on bioplastic because of its potential for causing a biological shift away from producing plastics based on petroleum, a shift that is already well underway. If, she wrote, “…plastic (a material with such great range of use in our daily lives) can be manufactured by the use of banana peels (a material which is thrown away every day), then this plastic would become a rival to the petroleum-based plastic we use nowadays”.

Eat the fruit, turn the peels into bioplastics.

Eat the fruit, turn the peels into bioplastics.

“The reason why I was able to [make bioplastic from banana peels] was because fruits rich with starch are preferred in the making of bio-plastic and the banana peel is rich with starch.” A more detailed description of Bilgin’s process and her experiments can be found here.

The young lady was working on her project long before she knew about the Google Science Fair. When the project was nearly complete she began looking for a competition to enter. Not surprisingly, she used the Google search engine to look for “science project competitions.” Surely you can guess what came up as the first result. Bilgin calls it a happy coincidence.

The Google Science Fair is an online competition open to student aged 13 to 18 from around the globe. We in America often hear of the decline in the national educational system. It should be of some comfort to know that of this year’s 15 finalists, eight are from the USA, and the winner of the 17-18 age group and the Google Science Fair Grand Prize, is Eric Chen, a 17-year-old junior at Canyon Crest Academy in San Diego, CA.

Chen’s project is Computer-Aided Discovery of Novel Influenza Endonuclease Inhibitors to Combat Flu Pandemic. One of his idols is Dr. Jonas Salk, the discoverer of the world-changing polio vaccine, and Chen has already served as a teaching assistant for college-level classes at his school.

Given the advanced nature of the projects in this competition, using the term school kids to describe the young scientists feels totally inappropriate, but whatever we call them, it is reassuring to know that these youngsters are moving into the scientific mainstream. Kudos to Google and Scientific American for encouraging and recognizing them.

The awards were presented on September 23, 2013 at Google’s Mountain View, CA campus, with all 15 of the finalists brought in for the event. Should you know of a budding scientist that should be involved in the Google Science Fair, the competition will re-open for entries in January 2014. In the meantime, updates are available from Google here.
