New Passivation System Added to MicroGroup, MN Manufacturing Platform


MicroGroup, Inc. is pleased to announce the addition of an ESMA E992 Passivation System to its Twin Cities, MN facility. This self-contained, fully-automatic system differentiates itself from less efficient conventional systems in that the work is performed by moving the fluids and not moving the parts. This investment is an ideal complement to MicroGroup’s core manufacturing services and further qualifies MicroGroup as a value-added, one source supplier.

Said Scott Zenner, director of operations, MicroGroup, Twin Cities, MN, “The installation of the in-house ESMA E992 Passivation System is part of our vertical integration strategy to provide our customers with improved process controls, shorter lead times and reduced costs.”

MicroGroup New Passivation System

Highlights of the new system include:

  • Substantial sized base unit can accommodate medical device components and instruments up to 24"L x 14"W x 12"H
  • By using a series of fill-and-drain sequences and repetitive clean and rinses with essential fluids, proper cleanliness and a spot-free finish are assured
  • Process automation eliminates potential operator error or overexposure of parts
