Frequently Asked Questions

What types of materials can you cut with waterjet?

We can cut virtually any material, including metals like stainless steel and aluminum, composites such as carbon fiber and G10, plastics like UHMW and nylon, and even exotic alloys such as Inconel. Waterjet cutting avoids heat-affected zones, making it ideal for materials that are sensitive to temperature or prone to warping.

Can you handle both prototypes and large production runs?

Yes, we specialize in both low-volume prototypes and high-volume production. Each job, whether a single custom part or thousands of components, receives the same attention to detail. Our engineers optimize cut layouts to minimize material waste and ensure timely delivery.

How thick can your waterjet cut, and how precise is it?

Our systems can cut materials up to 6 inches thick, maintaining exceptional edge quality and tight tolerances. Even when cutting thick metals or multiple layers, we ensure consistent precision. This allows for complex shapes and critical parts to be produced without secondary machining.

What certifications and quality measures do you maintain?

WaterJet West is ITAR certified and pursuing AS9100d / ISO9001 certification. Every part receives thorough inspection, and we provide material certifications and Certificates of Conformance to guarantee reliability.
