Advanex Europe Ltd

Previously it was thought that a micro spring of 30 µm wire diameter and a 90 µm inside diameter was the worlds’ smallest spring. Through their ongoing research and development, Advanex have been able to produce a working spring with a wire diameter of 15 µm and an inside diameter of 45 µm. Further work is now underway to produce a micro spring with a 9 µm diameter wire and an inside diameter of 30 µm.
