Spring Wire

Modern Grinding offers Spring Wire and wire coiling manufacturing services. We have dedicated machinery to automatically coil around a mandrel and cut the coil to length. Since this is automated, we are able to coil wire at a very competitive rate. Our coils are typically manufactured for medical guide wires.


We are able to turn stainless steel and nitinol into springs. We can coil standard wires or flat wires into coils.


Our coils are wrapped around mandrels which allow the coils to have a constant shape or custom shapes such as hourglass, tapers and steps in the middle of the coil.

Spring Size

Modern Grinding can manufacture springs as small as .001" and as large as 2" in diameter. We can do compression, extension and torsion springs.
