The acquisition of the second machinery factory in Shandong and Dongguan Mingdemao, so that the company quickly entered the first echelon of technology and scale of the MIM plate, enriched the application areas of the company's products, increased a number of consumer electronics and medical equipment industry, the first-line customers, the company's development is more closely related to the ever-changing information and communication technology, the development of the road to become broader. So far, the company has completed the expansion of the industrial territory of powder metallurgy new materials in stages, and steadily occupies the industry high point. It is the only enterprise in China that integrates PM, SMC and MIM, three mainstream or trending growth technologies in the powder metallurgy industry, and it is the largest and the world's leading manufacturer of powder metallurgy compression molding structural parts in China, and one of the largest metal injection molding structural parts manufacturers in China, and also a leader of metal soft magnetic powder cores in China. leading manufacturer of metal soft magnetic powder cores.

Comprehensively develop multi-industry and multi-scenario applications of the MIM process, explore the development of Ceramic Injection Molding (CIM) and Buck Metal Glass (BMG, commonly known as liquid metal), and utilize our technological advantages to attract new industries and new customers, as well as develop the consumer electronics industry and the Automotive, medical equipment and other long-cycle industries; Dongguan Mingdemao to take full advantage of its proximity to China's mainstream consumer electronics industry agglomeration of location, continue to develop the plastic, silicone, MIM hybrid process under the structural parts of wearable devices and flexible screen spindle represented by the MIM parts. Relying on the strong MIM structural parts production technology capabilities, will further expand the spindle design and assembly business. To this end, the Company has optimized the layout of the MIM industry and built three bases of the MIM industry, i.e. the R&D center, marketing center and manufacturing demonstration center of Dongguan Harber MIM industry, the low-cost, large-scale and modernized Lianyungang MIM production base, and the high-quality, close to the industry chain, large-scale and modernized South China MIM industry base. Folding screen cell phone has become a hot spot, around its folding axis parts weight reduction and durability requirements, the company invested in the development of low-density high-strength steel and ultra-high-strength steel and other MIM new materials, and achieved stage-by-stage results.

For the shell parts of smart wearable products with high appearance requirements, through a specially designed powder metallurgy sintering process, the company has developed enhanced non-magnetic MIM new materials with a high degree of densification, and the crush strength of the products exceeds that of forged materials, and the appearance quality meets the requirements of the customers.The average growth rate of China's metal injection molding industry in 2019 will be about 18%.

Soft Magnetic Composite Metal (SMC) in Power Electronics

In the field of new energy, the main application is soft magnetic composite metal (SMC) in power electronics. The soft magnetic materials used in power electronics mainly include soft magnetic ferrite, metal magnetic powder core, amorphous nanocrystal, silicon steel, etc. With the development of power electronics to high frequency, miniaturization and high power density, there are higher and higher requirements for the miniaturization of magnetic devices and loss, etc. The metal magnetic powder core is mainly used in the scenes of PFC inductors, lifting inductors, output filtering inductors, power inductors, and storage inductors, etc., because of its excellent resistance to saturation and its ability and its ability to be used as an inductor. Due to its excellent saturation resistance and good high temperature characteristics, it is gradually replacing other soft magnetic materials and is widely used in inductors, providing powerful material support for miniaturization and reliability of power electronics. Power electronics applications covering new energy photovoltaic inverters, new energy vehicles, charging piles, active filters, these areas are closely related to China's strategic planning and energy saving and emission reduction, with the increase in investment in the country's new infrastructure this year, the above industry is expected to achieve more rapid development. With the development of automobiles to electrification, intelligentization and automatic driving, on-board power supply and electronic control system are more and more used in the field of new energy vehicles. Metal magnetic powder core as the core material of energy storage and filter inductor is widely used in new energy vehicles on-board charger, on-board DC converter, hybrid motor control system, on-board 48V control system and other on-board power supply field.

Make a Big Breakthrough in the Application of Automobile Field and Form Incremental Business

With the improvement of powder metallurgy densification technology, processing technology and material system development, powder metallurgy to replace the traditional manufacturing process (forgings, castings, machining) space can be further expanded. The company has more room for import substitution and global market expansion of powder metallurgy products in the automotive industry.

From the perspective of MIM manufacturers, although large domestic MIM enterprises have cultivated automotive parts as a key direction for future development, the key problem to be solved is to match the strict requirements of the automotive industry in terms of product research and development, production organization and quality management. At present, the domestic has formed a certain scale of MIM automotive parts products are: diesel engine VNT supercharged turbine blades and forks, automotive door locking components, automotive seat adjustment components, fuel system high-pressure oil pump components, interior components, engine valve rocker parts, automatic transmission shift slider, etc., and in the future, the main focus is on the development of high-strength, high-temperature-resistant, low defects in the materials and processes, in order to strive for more key projects. major projects. The company has accumulated rich customer resources in the automobile industry in the field of powder metallurgy press molding, and formed a mature management system and corporate culture adapted to the characteristics of the automobile industry, which is expected to haul the company's MIM technology segment to make a big breakthrough in the application of the automobile field and form incremental business. 

The mass production of sintered aluminum alloy sprocket makes the company become the only company in China that independently masters the sintered aluminum alloy preparation technology, which makes a pioneering contribution to the energy saving, emission reduction and lightweighting of automobiles; the development and mass production of powder forging connecting rods breaks the monopoly of foreign technology; and the mass production of powder metallurgy surface densification products, helical gears, and large-tonnage gearbox parts.

Among them, aluminum alloy is currently the most promising application, sintered aluminum alloy parts will be the combination of aluminum alloy's lightweight and powder metallurgy's two major advantages of low carbon, can replace some of the iron-based parts, has been in the automotive lightweight application of a great show. In some high-end applications, magnesium-based parts have also been used, with technological advances, the complexity of the structure prompted by its powder metallurgy manufacturing process will also be gradually promoted!
