Founded in the 1960’s by our parents , Frank & Loretta Dvoracek, who built the business into a highly regarded contract injection molding business serving the design and manufacturing needs of a diverse customer base. As overseas competition eroded margins in the injection molding business, we focused on the design and production of proprietary plastic products. And, although we continue to provide contract injection molding for others, our primary focus is on traffic control and safety devices which we market under the name Three D Traffic Works.
