As of March 1, 2007, MARRV, the Manufacturing Alliance of the Rock River Valley, officially became a part of SupplyCore.  The Rock River Valley Area encompasses Winnebago, Boone, Ogle and Stephenson counties in northern Illinois.  Created in May 2004, MARRV’s original purpose was to combine the core competencies of small manufacturers to pursue larger projects than the individual companies could pursue on their own.

Integrated Manufacturing

MARRV offers complete manufacturing solutions from design and engineering to manufacturing and assembly. It was created to identify new opportunities for manufacturers, and to bring small- and medium-sized manufacturers together to provide large-scale and competitive bids to a wider global market. Combined with SupplyCore’s infrastructure, MARRV provides a single, streamlined source for aerospace, military, and other industries such as packaging machinery, heavy equipment, and transportation industries. 

MARRV’s supply chain management eliminates the time you would have spent identifying and qualifying new suppliers and their capabilities, and combines the talents of the most appropriate manufacturers to get the results you want, large or small.




Flexible Networks

MARRV specializes in developing inter-company collaborations between reputable manufacturers designed to best meet its customers’ needs. MARRV works hard to have redundant sources of supply through its flexible networks to minimize risks and limit possible delays. 

Currently with more than 80 members, MARRV is able to meet just about any manufacturing need. MARRV also offers a streamlined bid process that provides fast, accurate and competitive quotes.
