Drum plugs need to be screwed into flange bases on drum top. This procedure could be done manually in small scale production. The 55 gallon drum capping machine was invented to improve efficiency in assembling drum bungs, which integrates several necessary functions into one line.
The drum capping machine runs at a constant speed, which helps to keep high production efficiency and better consistency of steel drums. Functions and designs are adjustable according to actual layout of drum production line.
