Metal bellows molding machines is the special equipment which manufactures the metal bellow for prestressed concrete, makes the galvanized steel strip coil into double wave shape then undercuts and swages to apply the bellows. The bellows mainly used for prestressed pore of post-stressing prestressed concrete bridges\large-scale construction etc.
The machine has the advantages of small volume, compact structure, high efficiency, simple operation, easy maintenance; Is suitable for site or factory to focus on using. The bellows quality accords with JG225-2007 ""prestressed concrete with metal spiral pipe"" the standard requirement, and has good seal performance, facilitating construction. Dynamo adopts the infinitely variable speeds, so the tube rate is high, and high quality.
