Plastic caps serve many functions as industrial aids. Moisture, dust, and harsh substances are a few of the threats machine parts face. By being placed over the open ends of tubes and poles, plastic caps protect them from dirt and dust particles in the air.
Many companies also use plastic caps for thread and bolt protection. The caps are placed around the threads of screws and the ends of bolts to prevent damage and minimize the collection of unwanted dirt and grime.
Finally, plastic caps are used as paint masks during painting, powder coating, anodizing, electrocoating, electroplating, and other finishing applications. When placed around threads or equipment pieces, they prevent certain areas from being painted. This process is used when some sections of products need to be painted, but other sections do not.
