Waterjet and Plasma Cutting
Overview
High-Precision Metal Cutting for Custom Parts & Prototypes
Keystone provides in-house waterjet and plasma cutting services for metals, plastics, and composites. Waterjet is a cold-cutting process. It leaves no heat-affected zone and no distortion, cuts up to 6 inches thick, and runs two heads at once when you need identical parts. Plasma cuts mild steel up to 1 inch quickly and at lower cost, with a small heat-affected zone along the edge that suits structural and weldment work. Send us the drawing and we will tell you which process fits the part.

Frequently Asked Questions
FAQs About Waterjet and Plasma Cutting
We can process stainless steel, aluminum, mild steel, copper, brass, composites, plastics, stone, and more. The waterjet excels with delicate or heat-sensitive materials, while plasma is ideal for thicker metals and structural parts.
Waterjet cutting uses high-pressure water mixed with abrasive to cut materials without heat, leaving no heat-affected zone or distortion.
Plasma cutting, on the other hand, uses an ionized gas arc to cut through conductive metals quickly and efficiently — ideal for thicker steel and production parts.
Our waterjet can maintain tolerances within ±0.005", depending on material thickness. The plasma cutter typically achieves ±0.01" accuracy for most metals. Both provide clean, consistent results suitable for fabrication and assembly.
Waterjet: Up to 5' × 10' sheets and 6" thick materials
Plasma: Up to 4' × 8' sheets and 1" thick mild steel
Yes — we support both single-part prototypes and full production runs. With CAD/CAM integration, we can quickly program parts, nest them efficiently, and deliver fast turnaround for any scale of project.
Yes. We can assist with deburring, machining, drilling, tapping, and assembly as needed. Parts can also be prepared for powder coating, anodizing, or welding depending on your requirements.
