The millimeter that can completely change your design, a living hinge might be the most underestimated feature in plastic part design.

It is nothing more than a thin, flexible section molded directly between two rigid sections of a part. Yet it allows smooth, repeated movement without adding separate hinge components. The result is fewer parts, no assembly, and a cleaner design that lasts.

When made from polypropylene, a living hinge can flex millions of times without failure. The key is smart design choices. Multiple small hinges instead of one large one spread stress and reduce wear, extending the product’s life.

For manufacturers, this is more than clever engineering. It is a direct path to lower costs, faster production, and long-term reliability.
