Northern Iron And Machine Quality Standards

Since 1992, Northern Iron and Machine has held ISO 9001 certification for its foundry and machining operations. More recently, the company was awarded Transportation and Power Generation Certification (TPG) for its iron casting processes.

As part of these quality management systems, Northern Iron and Machine monitors size, soundness, hardness, and general workmanship using the following important processes and techniques.

During the initial production run of iron castings produced from a new pattern, Northern Iron and Machine performs a full dimensional layout. After a part enters into production, it is dimensionally verified based on the pattern’s cycle count which is a measure of molds produced on a given pattern. This dimensional verification of the casting is done to monitor tooling wear.
