Micro Springs
Precision compression, extension, and torsion springs are engineered for high-performance applications in medical, aerospace, defense, and electronics industries.
PRECISION SPRINGS DELIVERY REPEATABLE PERFORMANCE IN SMALL SPACES
Motion Dynamics manufactures precision compression, extension, and torsion springs that deliver consistent, repeatable performance where space is limited and reliability is critical. Our forming and coiling processes accommodate ultra-fine wire diameters—down to 0.0005″—and are optimized for miniature assemblies used across medical, aerospace, defense, and electronic applications.
We control every parameter of spring geometry—including pitch, coil count, free length, and stress distribution—to achieve exacting load, rate, and fatigue specifications. With in-house tooling, micro-inspection, and process validation, we ensure reliable performance at micron-scale tolerances from prototype quantities through high-volume production, supported by full traceability and lot certification.
Applications
- Compression springs for implantable valves, sensor assemblies, and precision delivery systems
- Extension springs used in retrieval mechanisms, surgical tools, and catheter deployment systems
- Torsion springs for controlled actuation in steerable catheters, valves, and miniature hinges
- Micro spring elements for aerospace and defense actuation or switch assemblies
- Custom-shaped and variable-pitch springs for complex motion or load requirements
- Prototyping and production-scale spring programs with validated performance and full traceability
Frequently Asked Questions
We specialize in precision compression, extension, and torsion springs made from ultra-fine wire, supporting applications where space, load accuracy, and reliability are critical.
We routinely form springs from wire as fine as 0.0005" (12 microns), maintaining precise control over coil geometry, free length, and load characteristics.
Our engineering and process development teams collaborate with customers to refine spring geometry, validate mechanical performance, and scale designs for production.
We manufacture springs in stainless steel, Nitinol, tungsten, Elgiloy, and Inconel, as well as other specialty alloys for specific performance or environmental needs. Finishing options include in-house ultrasonic cleaning, passivation, and proprietary chemical etching. Electropolishing is also available through our trusted finishing partners.
