Case Study: Ralco Industries achieves sub-1 PPM quality and real-time shop-floor control with Plex Systems

Ralco Industries’ Next-Generation Approach to ERP in Automotive Manufacturing

Ralco Industries is an Auburn Hills–based tier 2 automotive supplier (est. 1970) that produces high‑tolerance metal stampings and welded assemblies. With inventory turning more than 250 times a year and a long-standing culture of quality, Ralco needed to scale its processes and technology so operators could enforce quality, traceability, and continuous improvement without relying on error‑prone manual checks.

To do that Ralco implemented the Plex Manufacturing Cloud in 2001 and has since integrated the platform across sales, production, HR, shop‑floor equipment, and reporting. The cloud ERP enforces training, serialized traceability, role‑based dashboards and remote change control, giving real‑time visibility and proactive alerts; the result is sustained excellence (under 1 defective PPM for eight years), faster root‑cause analysis, stronger customer credibility, and ongoing operational improvements.
