Specification :

Cylinder machine shut pulls and draws alloy steel bottle flans with high strength from a wall
thickness 4.5mm down to 2.5-3mm in cold conditions. This machine applies a hydraulic
drive and operates stably. The drawing is done in one cycle without any
deformation, wrinkling or cracking. After drawing, the material is smooth and shining
on both inside and outside surfaces.

This machine is exclusively designed and manufactured for the high-strength and thin-walled
CO2 fire extinguisher (material is 35CrMo alloy steel) of a new generation
in both domestic and overseas markets. It has been used for many exclusive
export-oriented enterprises. The product features high qualification rate, high
automation and high speed. It only takes 30 seconds to pull and draw each bottle
flans on average. The product is an essential device for export-oriented steel
bottle manufacturers.
