Patti Engineering Successfully Completes Major Mitsubishi Control System Upgrade for Automotive Manufacturing Giant

Company’s engineering team updated obsolete control systems to assist in customer’s injection molded bumper project

Auburn Hills, MI – March 4, 2014Patti Engineering, Inc., a leader in control systems integration, today announced it has completed a project for one of the world’s largest automotive manufacturing organizations. Its team of renowned engineers conducted control system upgrades for three obsolete control systems on UBE Injection Molding Machines (IMM). At the completion of the project, the customer gained the many advantages of the technological advances in automation while extending the usable life of valuable capital equipment.

Patti Engineering is a Mitsubishi Authorized Systems Integrator and has extensive expertise using the Mitsubishi family of automation and process equipment. The Patti Engineering team was brought in by the customer to update the original Mitsubishi A Series PLC control systems installed on the IMMs, which Mitsubishi no longer supported. To avoid costly production downtime, the machines controls needed to be upgraded from the legacy A Series PLC to the new Mitsubishi Q Series PLC control systems. 

As part of this project Patti Engineering upgraded the Human Machine Interface’s (HMIs) on the IMM machines to current technology as well.  Patti Engineering recreated the functionality of the current Indusoft HMI application, and updated the operator interface PC to a 64 bit, Windows 7 system. This conversion ensures uninterrupted machine performance and reliability with the added efficiencies and functionality the modern technology provides.

“Patti Engineering’s longstanding history in revamping industrial equipment to keep up with the ever changing world of PLCs and other industrial controls has been paramount to the reputation we’ve earned as one of the best control system integration partners in the U.S.,” said Sam Hoff, executive vice president, Patti Engineering. “This project has further established our position in the market as a trusted partner, further proven by the fact that we are currently working on upgrading three additional UBE IMMs for this customer at the present time.“
