Micro-precise medical coiling

The deflection coiling process relies on the theory of elasticity and plasticity to produce helical springs of all types and forms. These fundamental principles make it possible to form wires as small as 0.0008" in diameter made of materials such as platinum, stainless steel, and tungsten into tiny medical device coils with outside diameters as small as 0.006". Due to their broad range of use, medical device coils typically have many stringent attributes pertaining to coil geometry, coil stiffness, and functional tolerances.

The deflection coiling process affords users the ability to produce coils in round and flat wires with variable outside diameters, variable coil pitch spacing, variable coil stiffness, and tight tolerances at nearly unlimited lengths. Kinecoil, Division of Kinefac Corp., provides multi-axis servo-controlled Micro-Coiler equipment, which transforms the theory into practice with superior process control.
