The contract manufacturer for rubber parts has added new equipment at its 70,000-sq.-ft. facility in Wayne, and is looking to expand in the next few years, said Jeff Leach, chairman and chief operating officer, during an interview at Rubber Roller Group's general meeting in Cincinnati, held May 5-7.Recently, the company purchased a new roll building line with "a fairly substantial investment," Leach said. The roll building line increases Passaic's capacity by about 30 percent, and is in the finishing stages of being installed.Passaic also converted its vulcanizer from steam to electric, which allows a greater level of control of temperature, Leach said.
