NORTHBROOK, ILL. (May 13, 2010)—Rogan Corp. has purchased two Sodick injection presses, with a third one coming later this year, as the company expands liquid silicone molding operations for medical at its plant in Northbrook.
Rogan got into silicone molding in 2006, by acquiring a general-purpose, reciprocating-screw injection press that ran LSR, according to Jim Ritzema, vice president of engineering.
“We were looking on the horizon and saw liquid silicone molding. We liked the potential growth and applications, and so we ventured into it, and continued to grow,” he said.
Rogan does compression and injection molding of knobs. The company is a longtime multishot molder of soft-touch parts using thermoplastic elastomers.
LSR is a totally different process: Liquid components are pumped in, then get heated inside the mold. LSR requires special pumping systems and molds.
After working with the original LSR press, Rogan officials began looking for something better. Rogan bought the first Sodick, a horizontal press with 40 tons of clamping force, in mid-2009. Sodick delivered a second 40-ton press — this time a vertical-clamp model — in January.
Rogan has added a Class 100,000 clean room for the medical work. The company focuses on value-added LSR jobs, such as silicone bonded to other materials, and post-curing to improve compression-set properties of LSR parts.
“Our plans are to expand our capabilities by adding a larger-tonnage Sodick this year,” Ritzema said.
