Michael Paloian, founder of Integrated Design Systems in Oyster Bay, N.Y., met Beall in the early 1980s when Beall asked him to join the SPE rotomolding division.
"He reached out to hundreds of us," Paloian said.
He added that Beall helped designers explore their creativity by combining what the product needed with plastics knowledge and innovation. As an example, he cited Oxo-brand storage units and kitchen tools. The tools have Santoprene TPV handles and sell at a premium price.
Mark MacLean-Belvins met Beall in the early 1980s, but even earlier he had used columns that Beall wrote for an industry magazine to better understand design and processing.
"My career wouldn't have been possible without what I learned from Glenn Beall," said MacLean-Blevins, owner of MacLean-Blevins & Associates Inc. in Westminster, Md.
"Early decisions about processing, material, design and tooling affect most of the potential for a completed part," he added. "And sustainability has to start right up front at the beginning of a project. It can be different for each one."
Mark Wolverton met Beall in the late 1970s when Wolverton was working for LNP Engineering Plastics. He's now with SPE's PlastiVan education program.
Wolverton credited Beall with helping him learn about the process of choosing a material. "Some materials aren't suitable for all processes," Wolverton said. "Materials can define a device and application in any market."
He cited the Black & Decker Snakelight as an example of successful product design. The product was a big seller when it was introduced at Home Depot stores in 1994.
Beall has continued to influence plastics pros well into his long career. David Tucker, owner of additive manufacturer New Wave Manufacturing in Camas, Wash., met Beall in 2019, after Tucker read a book that Beall had written about rotational molding.
Tucker said Beall taught him that "it's important to put new products on shelves instead of just focusing on savings."
Tucker said that additive manufacturing is "an enabling technology." He cited Invisalign teeth straighteners as an example of good design.
Ed Probst talked about Beall's impact on the thermoforming sector. Probst began his plastics career in the early 1980s with Profile Plastics in Lake Bluff, Ill., and now is principal of Probst Plastics Consulting LLC in Milwaukee. "At that time, thermoforming was a different process in different places, and we weren't always making great products," he said.
Beall — working with information from the SPE thermoforming division — wrote the first thermoforming design guide for Arrem Plastics in 1985.
Probst said that first guide "got attention because it had Glenn Beall's name on it. He had the reputation and experience and was well known in injection molding. A lot of us had attended Glenn Beall design seminars."
From that point, Profile and other firms made their own design guides, but Beall had laid the foundation.
"The importance that Glenn Beall has had to our industry as a whole is that he taught us how important it is to get people educated in the design of parts," Probst said.
Michael Sepe, Scott Peters, John Bozzelli and Eric Foltz also spoke at the Beall symposium, which was moderated by Al McGovern.
