When it comes to Waterjet technology, Hartwig, Inc. partnered with Flow International Corporation, both the pioneer and leader in waterjet technology. Flow began operations in the United States in the mid-1970’s when it developed Pure Waterjet Technology. Now there are two major technologies, Pure Waterjet, which cuts with just water and pressure, and Abrasive Waterjet, which adds an abrasive such as crushed garnet to the water. Flow, using their expertise in both technologies leads the field cutting metals, glass, stone, food, personal hygiene products, paper, and just about anything else you can imagine. You can find Flow products all around the world in every conceivable type of facility from a small job shop to the largest manufacturers in the world. Hartwig, Inc. is proud to bring you, our Midwestern manufacturing partners, these outstanding resources. Click on the logo or headline to visit Flow's website.
