The corrugated elbow forming machine is a duct elbow making machine that consists of two parts: the round duct corrugating machine and the corrugated duct pipe bending machine. It can efficiently process corrugated elbows with diameters from 100-250mm. The corrugated elbow forming machine first forms plain cylindrical tubes into corrugated straight duct pipes, and then the bending machine further bends these ducts into any desired elbow angle from 0-90°, greatly simplifying field installation. This metal elbow forming equipment uses a forming process where the sheet metal is crimped before bending. This method ensures fast production speed and high efficiency, while remaining simple to operate with low skill requirements for personnel, making it ideal for manufacturing various small-diameter corrugated elbows.







This duct elbow making machine is suitable for producing corrugated elbows used in small-diameter ventilation duct systems for various buildings such as hotels, residences, and shopping malls. It can quickly produce corrugated elbows with diameters from 100-250mm to meet diverse installation requirements.
