CASMI is the Chicago Association of Spring

Manufacturers, Inc. An independent, not-for-profit trade association, CASMI's Primary Membership consists of companies that engage in the contract manufacture of springs and precision metal forms as a primary activity, and whose products are sold to other companies as piece parts assembled into customers' products, rather than their own proprietary products. In 2015, CASMI began welcoming Associate Members, or suppliers, to the organization. CASMI is proud to host the biennial international trade show SpringWorld® at the Donald E. Stephens Convention Center in Rosemont, Illinois.
