“Now, laser cutting machines and plasma cutting machines account for 70% to 80% of the market share of the whole cutting machine, and the growth rate is very fast. However, the key components of laser cutting machines that can be manufactured in China and the international advanced level are still very large. Gap, and it is not yet possible to manufacture the key components of the plasma cutting machine.†On May 15, at the 13th Beijing Essen Welding and Cutting Exhibition held at Beijing China International Exhibition Center, Wuhan Falilai Cutting System Engineering Co., Ltd. Xiong Yanjun, general manager of the company's plasma division, told reporters. Details:/
For this exhibition, exhibitors gave a higher rating. An employee of the British company Kewell Welding Company stated that the company has participated in the 5th and 6th exhibitions, and the exhibiting results have been very good. They are most concerned about the latest technology. A staff member of Shanghai Nice Industrial Equipment Co., Ltd. believes that there are a large number of professional visitors at the exhibition and they have achieved the expected results.
The distance between 20,000 watts and 4000 watts Xiong Yanjun introduced that in the laser cutting control system and other aspects, the domestic laser cutting machine has completely reached the international advanced level. However, for the development and manufacture of lasers, the most important component of laser cutting machines, the gap between domestic lasers and the world’s most advanced lasers is 4000 watts and 20,000 watts, which is the maximum power of lasers manufactured by TRUMPF. It has reached 20,000 watts, while the Chinese laser can only reach 4000 watts.
"The greater the power of the laser cutting machine, the thicker the plates can be cut." Xiong Yanjun pointed out that the 4000 watt laser cutting machine can only cut steel with a thickness of 20 mm. If it is for thicker steel, the laser cutting machine for domestic lasers There is nothing I can do about it.
"Actually, the company also tried to develop more powerful lasers. However, after purchasing parts and components, it discovered that the performance of most of the components could not meet the requirements. In addition, the technology content of lasers is very high. Therefore, the performance of domestic lasers is natural. It is impossible to catch up with the performance of advanced lasers in the world, and to catch up with even the most advanced lasers in the world must be organized by relevant national departments. Last year, the Ministry of Science and Technology formulated a national science and technology support plan, which includes the development of high-power lasers. The goal is 6000 to 7000 watts. It can be seen that the gap between domestic lasers and the world's most advanced lasers is far." Xiong Yanjun analyzed. He reluctantly pointed out that although domestic lasers have a big gap with the world's most advanced lasers, at least they can still be produced domestically. This is not bad compared to the plasma power supply, which is the core component of plasma cutting machines that cannot be produced at home.
When to break zero? Where is the laser cutting machine?
Xiong Yanjun pointed out that the most commonly used plasma power sources in the country currently come from three companies: The first is Hypertherm, which has the largest sales of plasma power due to moderate prices and vigorous development of the Chinese market, accounting for 70% to 80% of the Chinese market. The second is the United States Fimat, only introduced to the Chinese market in the past two years, but because of its similar price, performance and Hypertherm plasma power, so sales grew faster; the third is Kelber, Germany, they produce plasma power technology The most advanced, best performance, and most expensive, widely used in Europe, but in China, it is difficult to find traces in the past few years, but in recent years, due to the rapid development of China's economy and continuous improvement in the level of consumption, its products in China Market sales are steadily rising.
“Whether at this exhibition or in practical applications, it is difficult to find domestic plasma power. It is different in Japan, such as the plasma cutting machine produced by Koike, and all parts and components are produced by the company.†Xiong Yanjun reluctantly He told reporters that when he first entered the industry, he was also very surprised that China did not produce plasma power because plasma power had a relatively low technological content compared with lasers. In fact, domestic research institutes have also successfully developed plasma power supplies, but their reliability, stability, and longevity are far lower than those produced abroad, and they cannot be put into production at all. The laser cutting machine transaction is a top priority.
Xiong Yanjun said that in terms of plasma power sources, China has 30,000 to 50,000 units of demand each year, and the demand is still growing, but this market is completely occupied by foreign companies. As China becomes a manufacturing center, cutting and welding as the first process of production and processing will inevitably require further development.
