Meichang new material: practicing internal strength to meet the development of electroplating diamond line industry

“The company was registered in July 2015. Since the production started in February 2016, the production line has not stopped the expansion of production capacity. The electroplating diamond wire produced has been in short supply.” Wu Ying, Chairman of Yangling Meichang New Materials Co., Ltd. Said, "The company built production lines last year and put it into production. In the same year, it achieved operating income of 183 million yuan and net profit of 95 million yuan. This year our production capacity is increasing every month, reaching 800,000 km/month by the end of the third quarter."
The electroplating diamond wire produced by Meichang New Materials is currently mainly used in the field of monocrystalline silicon and polycrystalline silicon in the photovoltaic industry. “Our competitors are Japanese companies.” Wu Ying said, “Only by staying ahead in technology, we can surpass them in price/performance ratio.”

Breaking Japanese technology monopoly to achieve import substitution
Electroplated diamond wire saw technology originated in Japan, and the market has long been occupied by Japanese manufacturers. Before 2015, domestic similar products depended on imports, and the cost was high. The market price of imported 80um diamond wire in Japan was as high as 0.4 yuan/meter. After 2015, some domestic manufacturers increased their research and development efforts and introduced Japanese production technology and equipment to form a certain competitiveness.
With the launch of Meichang's new 80um and 70um diamond lines, the prelude to the quality improvement and price reduction of the electroplating diamond line industry was opened. The price system of foreign mainstream diamond line suppliers was penetrated in the early stage, and they also cut prices to seek market share. Will not shrink quickly.
“Although the company started later than others, we can avoid the detours that the predecessors have gone through, and every product technology innovation will bring disruptive results to the diamond line industry.” Jia Haibo, general manager of Yangling Meichang New Materials Co., Ltd. One of the leaders in the company's electroplating diamond line technology breakthrough, he said, "Mei Chang new materials spent 1 billion yen in December 2015 to purchase Japan's advanced production lines and production technology, while absorbing and digesting Japanese technology, design And improved its own production equipment, forming the world's leading electroplated diamond wire equipment technology with independent intellectual property rights.
With its own research and development of production lines and technical processes, Meichang New Materials officially put into production in February 2016, the sales volume of that year jumped to the top of the domestic electroplating diamond line enterprises, reaching 1.2 million kilometers. As of March 2017, the company's annual production capacity has reached 4 million kilometers, and the annual production capacity can reach 10 million kilometers after the completion of capacity expansion before the end of September.
Wu Ying believes that although Meichang New Materials entered the electroplating diamond line industry late, the company's R&D team has been working on electroplating diamond wire research and development since 2010. After thousands of trials and technical improvements, it has become the only company in the world that can stably supply more than 300,000 km/month (70um, 65um, etc.).
"In terms of price, cutting yield and cutting efficiency, the electroplating diamond wire produced by Meichang New Material can completely replace the similar imported products from abroad." Wu Ying said that the company's products have been continuously optimized within one year and quickly become an industry. The core suppliers of mainstream monocrystalline silicon, polysilicon manufacturers Longji, Artes, Jinko Energy, etc., have completely changed the history of downstream crystalline silicon chip companies relying on imported Japanese diamond wire.

Work with PV companies to reduce wafer costs
Electroplated diamond wire is not a standard industrial product. It involves a large number of communication test work with customers. The change of technical parameters such as the transformation of cutting machine, cutting line speed and cutting tension of the cutting machine factory will involve the production process of diamond wire. With the adjustment of relevant technical parameters, the electroplated diamond wire enterprises need to maintain close technical exchanges with relevant manufacturers and provide personalized and comprehensive efficiency improvement solutions.
Jia Haibo said that the company's technology and product advantages enable the company to design, manufacture and organize integrated diamond wire applications according to customer needs, including diamond wire dimensions (diameter, length, etc.) and custom wire sizes (0.5 to 1.5 m/ Sheet), cutting time (1~3 hours/knife), adjustment of line depth, matching equipment and customer process, can provide tailor-made wire saw products for different models of different customers.
According to reports, the company's unique production line equipment investment is only one-third of the industry's similar, compared with the industry equipment single-machine single-line or single-machine two-line production mode, the company's original single-machine six-line production mode has increased production efficiency by 3 to 6 times. The production cost has dropped drastically. The production cost per meter of electroplated diamond wire is less than 0.07 yuan, while the industry average cost is above 0.12 yuan.
At present, the diamond line industry is still in the early stage of technical barriers. Jia Haibo believes that the core competitiveness of Meichang New Materials lies in the independent research and development of production technology and production equipment. The company still has great potential in the process of subsequent process technology upgrade and equipment improvement efficiency.
Jia Haibo said that Meichang New Materials has firmly adhered to the technological innovation route from the beginning of entering the diamond line industry. At present, in the measurement of the most important indicators of diamond wire performance such as cutting yield, filming rate, cutting efficiency, our diamond wire can fully meet or exceed the quality of similar imported products, and is one of the best in the world.
“From equipment, key materials, processes to system inspection and management, we are all self-created.” General Manager Jia Haibo introduced, “In maintaining the company’s continuous technological leadership, Meichang New Materials attaches great importance to technological innovation, from workers, Equipment maintenance personnel, technology and R&D personnel carry out industrial innovation in multiple dimensions. In 2016, we have achieved more than 100 innovative projects and applied for dozens of technical patents. We are also continuously optimizing the core material formula. There is a new breakthrough in one link."
Wu Ying, the chairman of the board of directors, introduced that the single-machine six-line production mode unique to Meichang New Materials not only has low investment, but also is easy to install and put into production faster. The domestic similar enterprises have completed the annual production capacity of 1 million kilometers. It is estimated that the equipment investment will exceed 90 million yuan, and the installation and commissioning cycle will take at least 6 months. The company's unique production line equipment investment does not exceed 30 million yuan, can be completed and put into production in two months, greatly reducing the capital demand for capacity expansion.
“At present, our production lines are all running at full capacity. The electroplating diamond wire has been in short supply since its listing in early 16 years. Now the order has been placed at the end of June.” Wu Ying said, “With the expansion of production scale, the cost Can also be reduced, the company's competitiveness will be further enhanced."
"We have always hoped to contribute to the development of China's photovoltaic industry and the promotion of peace and price online." Wu Ying said, "The photovoltaic energy industry pursues parity online, one of the key links is that the silicon manufacturing process reduces non-silicon costs. Technically The only way to be undisputed is to use diamond wire instead of sand wire cutting. However, the diamond wire is technically difficult and costly. Therefore, the technological progress and globalization that promote the manufacture of diamond wire are vital to the development of the industry. The largest diamond line manufacturer, rooted in innovation, the pursuit of excellence, is duty-bound, and the photovoltaic companies work together to provide continuous support for the price level of photovoltaics."

Practicing internal strength to meet the great development of the industry
According to data from national authorities, the global installed capacity of photovoltaics in 2016 was approximately 73 GW, a year-on-year growth rate of 38%. As of the end of 2016, China's photovoltaic power generation has a new installed capacity of 34.54GW and a cumulative installed capacity of 77.42GW. The installed capacity continues to maintain a relatively fast development rate. The newly added and cumulative installed capacity are ranked first in the world, consolidating China as the world's largest PV. The status of the market.
The electroplated diamond wire developed by the company quickly gained recognition from downstream enterprises after it was put into the market last year. It has become a dark horse in the electroplating diamond line industry, accounting for about 40% of the domestic monocrystalline wafer cutting market share. Of course, with the rapid expansion of the scale of downstream single crystal enterprises, the market demand for electroplating diamond wire will also rise.
General Manager Jia Haibo gave the reporter a courageous prediction. "The comprehensive popularization of polysilicon diamond cutting and PV parity online promotion will become a bigger explosion point for future company products."
According to reports, monocrystalline silicon is used in solar photovoltaic power generation, accounting for about 25%, and polysilicon enterprises, which account for 75% of the market size, have not yet launched diamond wire cutting on a large scale. Jia Haibo believes that "the technical necessity of polycrystalline silicon wafers is to use diamond wire instead of sand wire cutting, which will directly reduce the processing cost of silicon wafers. The company has entered the cooperation stage with several companies."
In 2017, Meichang New Materials first proposed the “four strategies” to lead the development of the diamond line industry, namely low TTV (slices), thin lines, fast cutting and line saving. The implementation of the four-in-one solution can make customers cut faster, produce higher, and have better quality, and ultimately the economic benefits will be greatly improved. The “four-oriented strategy” company has passed the test and practice of tens of thousands of kilometers of diamond wire cutting, and the effect is obvious, and it is stepping up and deepening.
Wu Ying believes that the implementation of the “four strategies” will win a higher market position for Meichang New Materials, and the leading edge will be more prominent. At the same time, it is necessary to transform Meichang New Materials from an electroplated diamond wire manufacturer to an integrated solution service provider. He said that looking at the world, we are now in the leading position in the electroplating diamond line industry. Whether it is compared with Japanese companies or American companies, we are very confident to consolidate our position in the industry.
It is understood that Meichang New Materials only supplied a single large customer of Longji Co., Ltd. from its initial establishment, and its products have now covered more than 40 enterprises in the industry.
In addition to investing heavily in wafer cutting, Meichang New Materials is also actively exploring and developing industrial extensions in the downstream applications of electroplating diamond wires, such as sapphire, special ceramics, magnetic materials and other industries for the application of diamond wire, and this or It will be another development focus in its future period.

Observed:
In the production workshop of Yangling Meichang New Materials Co., Ltd., the reporter could not see the fuss of the start-ups, and more of them were standardized and orderly. The production line introduced from Japan in the past has become a supporting role. The company's self-developed single-machine six-line production equipment has become the mainstay. Each new production line is constantly improving the process, and the pace of technological innovation has never stopped.
The newly established company completed a profit of nearly 100 million yuan in the year of production, and the net interest rate is as high as 50%. It is expected that the profit will increase by multiples this year. This is a "miracle" for manufacturing companies!
Objectively speaking, the success of Meichang New Materials cannot be separated from the factors of time, location and people.
The production technology of Diamond Wire was first monopolized by Japanese companies. Although China is a big country in photovoltaic manufacturing, it has been passively accepting high-priced import lines, which has also made it difficult to reduce the cost of silicon wafers. As the earliest test line customer of Meichang New Materials, Longji shares in the company's New product testing stage, so that the products can be directly equipped with process and debugging parameters on its wafer cutting production line. Nowadays, more and more single crystal and polycrystalline enterprises have held an open mind and joined the team that supports the company's innovative experiments. All of these have made Meichang New Materials have the "time of day" conditions in the product development stage.
The company put the registration place in Yangling, and gained the advantage of “land advantage”. Most of China's PV companies are in the western region, and regional advantages determine the convenience of downstream supply. In addition, the standardized factory buildings provided by Yangling Industrial Park directly shortened the construction process of Meichang New Materials in the early stage. After the equipment was commissioned, the products could be produced, which laid the foundation for the profitability of the year.
The core "human sum" is the gene that determines success. Without long-term technological accumulation and talent advantages, it is almost impossible to develop a subversive single-machine 6-line production equipment by breaking through foreign technical barriers. The entrepreneurial management team put down the original company and moved to the west to fight. Chairman Wu Ying has a professional background and has studied in Japan. Before the establishment of Meichang New Materials, he has more than 20 years of experience in joint venture management and has also reserved sufficient financial strength. General Manager Jia Haibo is an expert in the electroplating industry. He has many years of technical precipitation in the work of central enterprises and a wealth of industry resources. At the beginning of 2016, the company invited experts from the diamond line production company from Japan to serve as technical director.
The combination of these factors has created a rapid development of the standardization of Meichang new materials.
Meichang New Materials' management team is not satisfied with the rapid expansion of production capacity brought by the strong downstream demand, and continues to maintain the leading position of the industry. It is their ultimate goal to reserve more advanced technology and technology to lead the industry development trend. The photovoltaic industry is only the starting point of the company. In the future, the diamond line has a broader market waiting for them to develop.
