ISO 9001 certified Micro Waterjet® LLC of Huntersville, NC machines precise custom components from sheet stock, using specialized abrasive water jet cutting equipment developed and manufactured by its parent company in Switzerland. The equipment can make cuts as narrow as 200 µm (0.008"), with a cutting accuracy of 10 µm (0.0004").

The main advantages of Micro Waterjet® technology are no Heat Affected Zones (HAZ), low process forces, and low thermal stress. It can cut a wide variety of materials such as metals, plastics, and rubber. Employing a sacrificial plate underneath, very thin materials can be cut. Micro Waterjet® exels at cutting materials such as Teflon®, Nitinol, Titanium, Stainless, and Composites.

Micro Waterjet® complements other 2D processes such as wire EDM, chemical etching, and laser cutting, where those technologies do not work well for a specific material, geometry, or application. Micro Waterjet® is not generally less expensive than other manufacturing methods, with the exception of wire EDM when cutting single parts having multiple internal features.

With low setup costs, the process is suitable for prototyping to low volume production quantities.
