When selecting an air hydraulic pipe bender for metalworking applications, several factors should be considered to ensure optimal performance and efficiency. These factors include bending capacity, bending radius, control options, and machine features.

Firstly, consider the bending capacity of the machine, including the maximum pipe diameter and wall thickness it can accommodate. Choose a bender that meets the requirements of your specific applications, whether it's bending small-diameter tubes for automotive exhaust systems or larger pipes for structural fabrication.

Additionally, consider the bending radius capabilities of the machine, as this will determine the minimum radius of bends that can be achieved. Select a bender with adjustable bending dies or tooling options to accommodate a wide range of bending radii, allowing for greater flexibility in shaping metal components.

Furthermore, evaluate the control options available for the bender, such as manual, semi-automatic, or fully automatic operation. Choose a control system that matches the skill level and preferences of your operators while providing the necessary precision and repeatability for your bending applications.

Moreover, consider the features and accessories offered by the bender, such as mandrel bending capabilities, multiple bending axes, and digital readouts for angle measurement. These features can enhance the versatility and functionality of the machine, enabling operators to produce complex bends with ease and accuracy.

In conclusion, when choosing an air hydraulic pipe bender for metalworking applications, it's essential to consider factors such as bending capacity, bending radius, control options, and machine features. By selecting a bender that meets the specific requirements of your applications and provides the necessary precision and flexibility, you can ensure optimal performance and efficiency in your metal fabrication
