Plastic caps are typically made through a process called injection molding. In this process, molten plastic is injected into a mold that is shaped like the desired cap.
Pipe caps are protective fittings used to cover the end of pipes to secure them from damage and contamination. They can be used for sealing the pipe during transportation and storage, or to close off plumbing lines temporarily or permanently.
A pipe cap is a type of pipe fittings, also known as heads, plugs, bulkheads, installed on the external thread of the pipe end to cover the pipes. Used to close the pipeline, the function is the same as the pipe plug.
Masking caps are protective covers used to shield specific areas of components from paint, coatings, or other finishing processes.
