If a spring snaps in a machine, it costs money. If a spring fails in a medical device, the stakes are much higher.

The medical technology (MedTech) sector demands a level of precision that leaves absolutely zero room for error.

When engineering springs for surgical robotics, auto-injectors, or pacemakers, traditional manufacturing rules go out the window. This guide breaks down the critical factors for medical-grade springs:

• Biocompatibility: Moving beyond standard steel to materials like Titanium alloys or 316LVM Stainless Steel that won’t react with the human body or medical fluids.

• Micro-Tolerances: We are talking about wire diameters thinner than a human hair, coiled with microscopic precision to deliver the exact dosage force in an auto-injector syringe.

At Muelles Gesal, our specialized micro-coiling CNC machines deliver the extreme reliability that the healthcare industry demands.
