Does your next project involve Nitinol? Here is one example of our manufacturing process and how we can help you.

We take your CAD model or file and design a heat setting fixture to hold the laser cut flat part or shaped wire form. This particular fixture is just two dimensional, but we have also built complicated three dimensional forms, especially for formed nitinol wire parts.
We take the file to be cut and process it on our custom fiber laser. We have the ability to cut parts with features as small as .002” and complete parts as large as 11.5” x 11.5”. Tolerances can be as low as .001” per inch. Thicknesses can range from .001” to .125”.
Here we have a laser cut NiTi part in the heat setting fixture. More complicated finished parts may require a fixture with multiple laser cut plates put into an assembly and welded or pinned together.
The fixture with the laser cut part is then dipped in molten salt and then quenched to cool it down quickly.
The bluish hue on the outside of the part is an oxide formed during the heat setting process. If needed we can remove the oxide by dipping the part in a nitinol deoxidizing acid. We can also do electropolishing if required.
This is the final part.
