One of the very few businesses that has been producing plastic components for almost a century is InsulFab Plastics. Frank J. Hanus established InsulFab Plastics in 1923 to meet the demand for a trustworthy business that could reliably provide top-notch contract manufacturing services. InsulFab started to establish a specialty in the precise machining and stamping of engineering and high-performance plastic materials as the business expanded over time. InsulFab has become one of the most reputable and reliable suppliers of tight-tolerance CNC machined and stamped plastic components in the market by consistently focusing on going above and beyond for our customers. InsulFab functions as an extension of our original equipment manufacturers.
