Necking-in & Closing Machines

The Spinning Necking Machine is a precision metal forming solution designed to reduce the diameter of cylindrical parts such as metal cylinders, gas tanks, and industrial containers through a controlled necking-in process. This equipment integrates CNC controls, servo systems, and multi-stage tooling to achieve high output, accuracy, and repeatability in neck diameter reduction. A spinning necking process is key in industries where precision sealing or reduced neck diameter is required for end closures.
