Precision Metalforming Association

The Precision Metalforming Association (PMA) is the full-service trade association representing the $137-billion metalforming industry of North America—the industry that creates precision metal products using stamping, fabricating, spinning, slide forming and roll forming technologies, and other value-added processes. Its more than 800 member companies also include suppliers of equipment, materials and services to the industry.

Our mission is to shape the environment of the metalforming industry, leading innovative member companies toward superior competitiveness and profitability.
