Founded in 1969 by David and Helen Zelnick, Zed Industries grew from a small vacuum-forming machine manufacturer into a Vandalia, Ohio, designer and manufacturer of custom thermoforming and plastic-packaging equipment. Its systems serve customers in more than 32 countries, backed by a service department with more than 40 years of combined experience and detailed documentation for every machine built. Zed also makes its own tooling and uses American-made components in more than 95% of its machines.
