About PMA

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 900 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.

PMA is committed to the value of diversity in our own workplace and in our industry. We know that the future of the North American manufacturing sector depends on creating and maintaining an environment in which all people feel welcome, comfortable and safe. As one of the largest metalworking trade associations in the United States, we are committed to continuing to partner with our member companies and others to recruit, train and retain people of all backgrounds for manufacturing careers that help to propel North America forward.
