Shape Setting
With specially developed tools and processes, complex three-dimensional structures can be formed without loosing the superelastic and shape memory behavior of the material. Nearly any shape can be manufactured out of Nitinol wire, tube and sheet material.
By adjusting the material transformation temperatures, the shape and function can be adapted to your special requirements. In Addition, we adapt your device to the surrounding conditions and to the environment in order to obtain the best possible performance out of the material and to optimize the function of your device.

FEM Optimisation
A software-routine developed especially for Nitinol properties allows us to analyse geometries by means of the finite-element-method (FEM). With the optimisation tool (CAO) we are able to find the optimal shape by reducing high loading strains and therefore increasing the lifetime of the device.

Micro Patterning with laser / EDM and grinding of mirco-strucutres
Find precise cutting, drilling and laser welding. The lateral structural accuracy presently attainable with th Nd:YAG laser goes down to 12 µm. The strucutre depth extends into the mm range. With wire cut edm there is no limit to the thickness of the material. The functional properties of NiTinol (thermals shape memory and superelasticity) are not influenced by laser or EDM treatment. A modern CAD/CAM system allows to diredtly cut your structure out of a digital master file (dxf, dwg format preferred) with an appropriate quality.

Grinding of micro-structures into wire and tubes
A precise grinding process allows to grind extreme fine structures into superelastic and martensitic Nitinol wires and tubes.
One of the most common grinded applications are dental root canal files.
Because of the superelastic properties, the files can follow even extremely curved canals.
Grinded superelastic needles and cannulas can be introduced through small working channels of endoscopes and trocars.
