When designing the core design factors of products adopting various Bellows, the following factors should be reviewed by considering customers' design and development information which determines the features of Bellows.
- limited dimensions of products (inner diameter, outer diameter)
- Stroke (maximum tensile amount and compression amount)
- Required features (spring constant, volume change rate, torque)
- Application conditions and environments (types of gas and fluid, internal and external pressure, application temperature, etc.)
- Required life cycles, corrosion resistance and endurance warranty year
|
The engineering activities taking into account the above design and development information proceeds by introducing the following basic output data.
- Determination of Bellows types and dimensions (types, cross-sectional shape of convolution, pitch, convolution height of Bellows)
- Determination of the optimized number of Bellows convolutions.
- Determination of the thickness and layers of Bellows by considering pressure and spring constant
- Material selection by considering corrosion resistance, life cycles, and endurance warranty year
- Determination of post-treatment process
- Forming mould design data
