Micro Spring Design Information


What are Micro Springs?

Micro springs are miniature mechanical springs designed to provide precise force, tension, or compression in very small assemblies. Despite their tiny size, they function just like standard springs.

They are commonly used in medical devices, electronics, aerospace, automotive, and other industries where space is limited and performance is critical. Micro springs often require extremely tight tolerances and specialized materials to ensure reliability and consistency at a small scale.

Newcomb Spring manufactures small springs to precise specifications, offering custom solutions based on your application’s unique requirements.
