WORCESTER, Mass.—Liquid silicone rubber has emerged as a preferred material for many of the parts being serviced by the Cryogenic Institute of New England, which brands itself as Nitrofreeze Cryogenic Solutions.
The Worcester-based firm provides a wide range of cryogenic services for the manufacturing, molding, medical device and aerospace industries. It also provides cryogenic deflashing and deburring services to remove flash and burrs from molded and machined parts with as little as a two-business day turnaround.
That move to LSR rather than more standard rubber materials has necessitated the continual "finessing" of ways to become more efficient, said Assistant General Manager Ryan Taylor. With the latest improvement, Nitrofreeze provides LSR molders with a faster and more efficient way to get flash-free parts without waste.
Previously, it was difficult to process on LSR, but over time—and with the lessons learned from countless hours of testing—deflashing has become simpler, allowing LSRs to run on a wider spectrum of end products.
"Now we can run anything that flashes," Taylor said. "We typically are running samples at least once every business day over the course of a month."
That is important, he said, because Nitrofreeze works on LSR for as much as 25 percent of its work. Traditional rubber was more dominant five to 10 years ago, but the versatility of LSR continues to improve in various elements, including outdoors in areas of high ultraviolet light.
