When Sonoco, the world’s largest producer of engineered carriers, continued to experience complaints about variation in the outside diameter of the cores that it supplied to its paper mill customers from its Midwest manufacturing plants, the company’s quality personnel knew something had to be done.
The company began using SPC Express software from Major Micro Systems (MMS, Southfield, MI) to evaluate its manufacturing processes. “We were already using in-line OD measuring devices but we did not have the tools to fully analyze the process,” says Ron Mooneyhan, regional quality engineer for Sonoco. “The end result was that we were not meeting our customers’ desired results.”
