Not only is plasma cutting cheaper than laser or waterjet cutting, but it is also more efficient, accurate and versatile than the use of oxy-fuel. Plasma cutting is definitely the way to go when manipulating strong and sturdy metal for heavy duty structures.
However, it’s strength and power also align with its superior accuracy, which makes it perfect for intricate jobs with thin metals too. Here are just a few of the ways you’ll be saving money by employing engineers who use plasma cutting to fabricate parts for your next project.
Faster cutting times
When cutting metals up to two inches thick, plasma cutting is twice as fast as cutting with oxy-fuel. So just think how much speedier cutting thinner metals would be! Plasma cutters also pierce the metal quicker, to begin with. Other cutting methods may need the metal to be pre-heated before piercing, adding extra time onto the process of cutting.
When cutting with plasma, there is very little leftover ‘dross’ created in the process because the metal cut is provided with superior protection from oxidation. Plasma cutting melts and blows away the molten metal from the cut as it goes. This means less time spent removing excess metal from the cutting process as there is no need to chisel or grind off the dross.
Generates less waste
The fast cutting times used in plasma cutting means that less heat is focused on the metal for prolonged periods. Therefore, thin metals are less likely to warp, and working time is slashed because distorted parts will not need to be discarded and started over. The smaller the waste generated, the less you’ll be paying for materials, too!
Works in conjunction with CNC Machining
Plasma cutting is often integrated with CNC machining and the assistance of robotics for large-scale manufacturing. This eliminates the need for extensive training and setbacks caused by human error. Robot plasma cutters can cut through an astounding 500 inches per minute – now THAT’S efficient!
Plasma cutters can cut through any electrically conductive materials. Most commonly, plasma cutters are used for all non-ferrous metals such as stainless steel, copper and aluminium. This also means that cutting several sheets of different metal simultaneously is possible; saving labour time.
