1. Metal bellows molding machine is the special equipment which manufactures the metal bellow for prestressing concrete, makes the galvanized steel strip coil into double wave shape then undercuts and swages to apply the bellows.
2. The bellows are mainly used for prestressing pore of post-stressing prestressing concrete bridges, large-scale construction etc.
3. 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.
4. The bellows quality accord with JG225-2007 prestressing concrete with metal spiral pipe the standard requirement, and has good seal performance, facilitating construction.
5. Dynamo adopts the infinitely variable speeds, so the tube rate is high, and high quality.
