FEBRUARY 2018 6 CompositesWorld FROM THE EDITOR » My first plant tour as a business journalist was in February 1997. I was, at the time, a senior editor at Injection Molding magazine and traveled up to northern Wisconsin to visit a custom injection molder there. I was traveling with John Bozzelli, who, at the time, had just launched a consultancy, espousing the virtues of "scientific molding." He had been called to this Wisconsin molding facility to help the company increase its operational efficiency. Scientific molding, as the phrase implies, is the application of scientific and mathematical principles to the injection molding process, and is designed to increase molding process consistency, reduce waste and increase finished part quality (sound familiar?). I remember thinking at the time that such principles certainly could/should have been applied many years previously. But, in fact, the molding industry's efforts to meet production goals were still beset by dependence on human operators. at is, there were, in many plants, certain people who "knew" how to make certain injection molding machines operate properly. Indeed, I once had a plant manager point to an idle molding machine and tell me, "Only Mike on third shift can make this machine and mold produce good parts." John's mission, early on, was to move molders away from this dependency by helping operators and plant managers to better understand the physics governing the injection molding process. e ultimate goal was to help molders build robust, repeatable molding processes that produce quality parts with little or no human intervention. e first step in this transformation was a machine audit, and that's what I witnessed in frigid Wisconsin — watching and learning as John assessed this molder's machines. Much of this work was basic math, verifying that what the machine's controls said the machine was doing was reflected in reality (often it was not), and then working to align those controls with reality. It was, basically, data collection, calculation, assessment and adjustment. If we are in or on the cusp of Industry 4.0 today, then what John and I were doing in 1997 must have been Industry Beta. Of course, getting molders to do simple math was not the highest hurdle John had to clear. e biggest barrier, more often than not, was not mathematical but sociological: Getting the company and its employees to change the way they think about manufacturing, to change the company management and shop floor culture — top to bottom — to embrace the concept of science-centric manufacturing. Fast forward to 2018 and suddenly what was old is new again. Science- or math-based manufacturing is now known as the Industrial Internet of ings (IIoT), or the aforementioned Industry 4.0. And while the overarching goals are the same — systematic, disciplined, data-based processing — the tools avail- able to us are much more sophisticated. Raw computing power, cloud-based data storage, remote sensing and artificial intel- ligence, unimaginable in 1997, now simplify and streamline the effort to harness the power and precision of data-based manufac- turing. And when implemented well, the results can be impres- sive, increasing efficiencies, reducing cycle times and waste, and ensuring the consistency and repeatability of composites manu- facturing processes. What has not changed, however, is cultural intransigence, the built-in institutional reluctance in a composites fabricator's facility to seek out and apply new technologies. e myriad (understand- able) reasons for this include lack of resources, lack of time, fear of change, uncertainty of results. What is certain, however, is that the entire composites industry, just as the injection molding industry did more than 20 years ago, must begin to embrace the systematic use of data, particularly if it expects to deliver the process control, production speed and product quality sufficient to establish composites as the advanced materials of the 21 st Century. Math, science, data and the composites industry's future. JEFF SLOAN — Editor- In- Chief
