Bending Sheet Metal vs Bellows Design Software
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Bending Sheet Metal
This app calculates the total flat length of sheet metal bends based on a specified K-factor. It also provides approximate K-factor values for different bending methods and material stiffness if the exact value is unknown.
- Total flat length calculation
- K-factor specification
- Approximate K-factor suggestions
- Material stiffness consideration
- Bending method analysis

The calculator counts the the total flat length according to the K-factor you specify. If you do not know the value of K-factor, then the program, determining the the total flat length, depending on the method of bending and stiffness of the material offers approximate values of the K-factor. The program helps to easily calculate the real value of K-factor for your material, tool, tooling, technology.
Bellows Design Software
This application assists in designing metallic bellows type expansion joints according to EJMA Standards. It allows users to input various design parameters and movement inputs to ensure safe and reliable usage. The software performs comprehensive calculations and checks against EJMA conditions for different bellows configurations and materials.
- Design metallic bellows expansion joints
- Input internal diameter, convolution height, ply thickness, pitch, and number of plies
- Set design pressure, temperature, and movements
- Check design parameters against EJMA Standards
- Calculations for single and dual bellows
- Includes vibration and bellows forming methods
- Calculations for tie rods, lugs plate, and hinges
