Modern plasma cutting CNC machines have more precision than their predecessors and cost less than laser and waterjet cutting services. With CNC plasma cutting GST Manufacturing focuses on superior precision and detail, making your final product the highest quality.​ Gas and electrical currents melt and cut the metal, which makes a plasma cut edge slightly rough with a beveled and rounded top edge. Plasma cutting burns through thicker material than laser cutting and waterjet cutting. Depending on the electrical current capacity and the type of metal, plasma cut metal UP to 1.5″ thick. CNC plasma cut metal is more economical than laser or waterjet cut metal.
