CNC Plasma Cutting

Rapid Execution. Industrial Scale.

High-Definition CNC Plasma Cutting Services

When fabricating massive industrial bases, offshore structural platforms, and heavy mining components, High-Definition (HD) Plasma Cutting is the premier balance of speed, economy, and precision.

Operating from our 180-acre manufacturing complex, Openex houses massive large-format plasma gantry tables spanning up to 20 meters (65 feet) in length. Powered by world-class generators, our systems deliver virtually dross-free edge quality, sharp internal corners, and tight profile tolerances on structural carbon steels, stainless steel alloys, and aluminum plates up to 100mm thick.

🌊 Advanced Underwater Plasma Technology

A primary concern with thermal cutting on large heavy plates is the Heat-Affected Zone (HAZ), which can cause metal warping and bowing. To completely neutralize this, Openex operates massive Underwater CNC Plasma Tables.

  • Virtually Eliminates Thermal Distortion
  • Superior Edges Requiring Less Secondary Milling
  • Greatly Reduces Oxidation on Cut Surfaces
  • Mitigates Hazardous Fumes and Airborne Dust

Integrated Plasma Bevelling for AWS Weld Prep

Multi axis plasma bevel head cutting heavy steel

Many massive assemblies, like pressure vessels and shipbuilding hulls, require precise V-bevels, Y-bevels, or K-bevels before submerged arc welding (SAW) can begin.

Our advanced CNC plasma machines feature fully articulated 5-axis contour bevel heads. This allows Openex to perform standard shape profiling and exact angle weld-prep chamfering in a single, fluid automated setup, radically accelerating production cycles compared to manual bevelling.
