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

Our complete line of protective closures includes plastic and dip molded vinyl caps, plugs and custom masking products.

PMI is an ISO 9001/2000 certified facility offering a completely staffed tool building, prototype and mold maintenance department. Founded in 1978 as an injection molder and tool builder of toy and consumer specialty products, our proprietary line of protective products was introduced in 1989. We continue to be a worldwide supplier of protective closures in the Aerospace, Appliance, Automotive, Construction, Consumer Products, Electronic, Fluid Power, Medical, Packaging and Powder Coating industries.

Although our standard line is produced in commodity (lead-free) grade resins, PMI also has substantial experience producing components in high performance Thermoplastics and Thermoset materials as well. ABS, Acetals Acrylics, Phenolics and Polycarbonates are just a few of the materials we process. Should environmental conditions, thermal endurance, close tolerance, impact stability, corrosion resistance or conductivity be an issue with your products, we may be able to help.
