SK490/640 CNC Gas Cylinder Necking Spinning Machine is a dedicated hot spinning equipment independently developed for seamless high-pressure gas cylinder neck forming. It adopts heavy-duty integral cast bed, dual/triple spinning wheel balanced structure and full CNC servo control system, specially designed for necking, shoulder forming and uniform wall thickness strengthening of steel & aluminum alloy gas cylinders such as hydrogen storage bottles, CNG cylinders, oxygen cylinders, LPG tanks and industrial pressure vessels.
Eliminating welding seams at bottle mouth via one-time hot spinning forming, this machine greatly improves cylinder air tightness, burst pressure and structural fatigue resistance. It supports batch mass production and small-batch customized trial production, widely adopted by gas cylinder manufacturers worldwide.
