Case Study: New York Air Brake reduces brake cylinder defects with Minitab Statistical Software

New York Air Brake - Customer Case Study

New York Air Brake, a leading producer of railroad brake systems, faced a costly rust problem on brake cylinders during hot and humid storage conditions. The issue was adding nearly $53,000 in annual costs and was part of the company’s broader Six Sigma goal to reduce defects; they used Minitab Statistical Software to help address it.

Minitab helped New York Air Brake apply DOE functionality to identify critical quality factors, develop corrective actions, and implement new controls in machining and assembly. With Minitab’s DOE Response Optimizer and statistical tools, NYAB eliminated manual trial-and-error analysis, solved the rust issue, and reduced its overall defect rate by 50%.
