Miniature torsion and extension springs are commonly used throughout today’s aerospace industry. These seemingly simple components feature in everything from basic ergonomic devices to state-of-the-art electromechanical equipment – including avionics, actuators, sensors, and aircraft control mechanisms. Given the highly sensitive nature of modern flight operations and passenger transport, every single spring must be manufactured to extremely precise tolerances and performance specifications.

One of America’s leading aerospace manufacturers specializing in micro spring components, HyTech Spring and Machine produces virtually all configurations of torsion and extension springs with wire diameters as small as .0015”, built to the most exacting requirements possible.

Aerospace Torsion Springs

HyTech manufactures the precision torsion springs built for extended cycle life – critical to the modern aerospace sector. Our torsion springs are typically installed within aerospace electronics and communication equipment, as well as various aerospace sensors and switches.

Some of the common specific use cases include fuel filters and shutoff mechanisms, along with various interior components such as seat belt components and luggage mechanisms. We produce a wide range of torsion spring types including left and right handed coils, single and double torsion with complex leg configurations in wire sizes from .002” round and shaped wire up to .178”.

• Axial torsion springs
• Tangential torsion springs
• Radial torsion springs

Aerospace Extension Springs

We supply aerospace extension springs of standard specifications and specialized needs, including a complete range of unique hook configurations. We can also manufacture specialized extension springs from exotic aerospace metals including 17-7 PH and Inconel X750 to meet the highest-performance requirements on the market.

Our extension springs are typically built from .002” diameter wire up to .178” diameter. Common applications include garter springs in aerospace seals amongst many other unique use cases.
