Compression Springs for Medical Devices

Precision in Motion: The Critical Role of Compression Springs in Medical Devices

Engineered for Reliability, Designed for Life-Saving Innovation

26/02/2025

Compression springs are essential in designing and performing autoinjectors, pen injectors, inhalers, OBDSs, and other medical devices. These small but powerful components ensure precise dosing, reliable activation, and patient safety.

At RPK Medical, we understand that medical-grade compression springs require advanced precision, where every detail matters. Material selection, force calibration, cleanliness, and durability testing are key to meeting ISO 13485 and industry regulations.

We can design your compression spring from the start of the product development process, where our experts provide early technical insights to minimize risks, costs, time, and potential failures. This approach ensures optimal performance by addressing the complex technical challenges of drug delivery devices from the beginning. While we can also manufacture based on an existing design, collaborating from the early stages offers more significant advantages in achieving a more efficient, reliable, and cost-effective solution.
