Industry Information

Plastic Plugs

Plastic plugs provide thread protection and can be used in paint masking applications. Plastic plugs are also useful for keeping equipment such as pumps, cylinders, valves and tubing clean. They are often used to protect products during production or when being shipped or packaged.

The process of dip molding is used to make plastic plugs. Dip molding is a thermal process that involves the preheating, dipping and post-heating of metal molds. Generally, automatic dip machines perform this process. High precision is used in plastic dip molding because the inside of the part is an exact negative of the mold, with the same surface texture of the mold. The outside dimensions are also controllable. Using precisely controlled ovens, dip speeds, dip times and withdraw speeds provides a range of wall thicknesses.

Types of plastic plugs include flange covers, tapered and threaded plugs, and static protective plugs. A variety of sizes and colors are available, or plastic plugs can be customized to meet specific requirements. Plastic plugs can be readily found in the automotive, finishing and HVAC markets.
