Polymer Molding, Inc. (PMI) is a U.S. manufacturer of plastic protective caps, plugs and custom moldings. These types of products are usually disposable and are commonly used to protect threaded fittings, tubing and valves and in many other applications where contamination or shipping damage needs to be avoided.

PMI was founded in its hometown of Erie, Pennsylvania in 1978 as an injection molder and tool builder of toy and consumer specialty products. In 1989, the company introduced its proprietary line of protective products and has grown to one of the leading producers of these types of commodities. The Erie facility has expanded over the years, but instead of trying to be the biggest, the focus has remained on exceptional customer service, quality and value.
