Steel Tube Necking-in & Closing Machine
The steel tube necking-in and closing machine uses hot spinning technology, primarily for necking-in and closing of steel tubes and pipes, especially in automotive shock absorber, motorcycle vibration dampers, SCBA cylinders, accumulator shells, small gas storage cylinders, boiler tubes, and chemical pipe industries.
We at Zhenhuan are a Chinese Steel Tube Necking-in & Closing Machine supplier. Our products have the following features
Main Features
- OMRON PLC control and Weinview touch screen operation
- Induction heating method, clean & quick
- Both necking-in and closing: The reserved hole diameter after necking-in can be freely adjusted, and the end wall thickness after closing can be increased for better pressure resistance with no need for additional welding.
- Closing end can be flat, spherical, ellipsoidal or pyramid shaped, and is easy to adjust.
- Automatic hydraulic clamping
- Necking-in & closing dies are made using a cobalt-base alloy. They are resistant to high temperatures, and feature a long service life.
- Compulsive lubricating system, prolonging life of dies
- Auto loading & unloading device is optional
