As two of the most popular metal cutting methods on the market, plasma cutting machines and laser cutting machines are both eye-catching on the market. Let ’s introduce them to you.
Plasma cutting machine
Plasma cutting is the heat of a high-temperature and high-speed plasma arc to partially or partially melt (and evaporate) the metal at the cut of the workpiece, while blowing the molten metal out with a high-speed airflow. The plasma cutting speed is fast and the deformation is small, but when cutting thick plates, there will be slopes.
Compared to laser cutting machines, the advantage of plasma is the price. If the cutting effect can be achieved within the required range, purchasing a plasma cutting machine can greatly save costs. The core component of plasma is the power source of plasma. The price of a plasma may be 50% to 70%, which is its main component.
Domestic power supplies are generally cheaper than imported, and people are pursuing the United States Hypertherm's plasma power supply. In fact, Hypertherm's cost performance is not very high. China is convenient for some manufacturers to do well here.
How to choose a plasma cutter
First determine the thickness of the metal to be cut, so that the current is determined according to the thickness, and each machine has the optimal thickness cutting range. You must choose the one that suits your requirements.
Then you can choose factory inspection and machine inspection. I only recommend these two ways to purchase equipment, not to mention Alibaba, e-commerce or anything, I understand, it is not reliable.
Why is the laser so hot now, what did you think about the laser before? It is expensive. I dare not think about it. A machine needs millions of yuan. At that time, the money was more valuable than it is now. Only high-end goods such as laser cutting machines can be owned.
However, the reason why lasers are now entering large and small processing plants is that it has reduced prices. The current price of laser cutting machines on the market should only be about 30% to 60%. The lower price of this range makes it gradually popular. But even so, it is expensive compared to a plasma cutter. However, the advantages of laser are also obvious, the cutting speed is faster, the accuracy is higher, and the cutting quality is better.
