Single or multi-convolution designs also influence the performance of a system greatly. Single-convolution performs well in situations where space is a serious constraint. Their simple design offers cost advantages in high-volume production scenarios. The multi-convolution rubber bellows deliver superior flexibility in complex installations. Industrial designers must carefully evaluate movement requirements before selection. Manufacturing processes have advanced in recent decades for bellows. This technological leap allows for precise engineering without extensive prototyping. The industrial sector increasingly demands customised solutions for special equipment.
