Plastic Caps
Plastic caps provide industrial protection in the form of protecting threads and keeping equipment clean during processes such as vibratory deburring and tumbling, shot blasting, and shot peening.
Plastic caps are formed through the process of dip molding. 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 required 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 provide a range of wall thicknesses.
Common types of plastic caps include round caps, round caps with tabs, angle caps, flat and rectangular caps, hex caps, and square caps, in addition to custom-shaped caps. Some of their applications include shipping protection, color coding, thread protection, industrial masks, connector caps, dust and moisture barriers, and many more. A wide variety of sizes and colors and lengths and thickness are available, or the plugs can be customized to meet specific requirements.
