I won't lie, Flow International's products can be a bit abrasive. But that's a good thing for customers in the aerospace, automotive, food, and paper industries, among others. The company (a Waterjet Holdings subsidiary) manufactures and supplies ultra-high-pressure waterjet and abrasive waterjet systems to both small shops and major industrial companies in more than 60 countries around the globe. Its waterjet machines, which come in both standard and advanced models, are used for cutting everything from metal and stone to food and paper. Additionally, Flow International  sells consumable waterjet system parts (such as seals and orifices) and services.
