Due to excessive growth of production capacity before and after 2003, 2004, during the 2005 to 2010 there will be more intense competition, the small scale and weak strength of the enterprise will face a severe test failures, mergers and acquisitions is difficult to avoid. Of course, from the amount of Chinese sintered NdFeB in the next five years is still a steady growth, and growing market share of high-end products like VCM, MRI, motors, etc. Expected that the sintered NdFeB in China from 2010 to 2015 will usher in a surge of development.
    Significant technological progress is difficult to expect from the process point of view. Mainly to further understanding in this regard, digestion, and improve existing technologies.
Performance in the following aspects:
(1) to further promote the hydrogen decrepitation technique.
(2) to further promote and improve the melt spinning technique, (3) alloying is possible to achieve a breakthrough.
From the device point of view, future work includes the following aspects: (1) 600kg to promote rejection of the belt furnace; (2) 100kg or 200kg
The development of the ingot mold (square-sided cold) melting furnace; (3) continue to improve the rotary-sided cold furnace, the capacity of each furnace should be able to reach 1 ton or 2 tons; (4) a new generation of hydrogen decrepitation furnace the design and promotion; (5) AFG400 jet mill design and promotion; (6) Improve the automatic presses (including automatic feeding and automatically take blank disc);
Solving the single-chamber sintering furnace (7), under the temperature difference between the big problem;
(8) the design, production and promotion of continuous sintering furnace.
From the production mode of operation, NdFeB plant are small and complete or large and, from melting until the sintering. Unlike Japanese companies, alloy plant is only responsible for the rejection band, magnet production plant to complete milling and sintering processes. In the next few years, China is also likely to alloy plant separated from the magnet factory, and even further, the establishment of several milling center (for example, in Ningbo, Taiyuan, Beijing and other places) to supply the majority of magnet manufacturers like Japan. Milling center is an advanced, in line with the further refinement of the concept of the modern industrial division of labor. Beijing Geely has begun the attempt to establish the center of rejection with the achievements of the past few years to prove that they are successful. Safety, capital investment and technical point of view, the hydrogen decrepitation magnetic powder will be more market to the magnet manufacturers. The future can also consider adding a jet mill, allowing users to directly use to wear a good magnetic powder. Milling center of the production, so it can be the purchasing power of rejection with furnace, melting furnace, hydrogen decrepitation furnace and jet mill (for example, the efficiency of a AFG400 jet mill is equivalent to 5 to 6 conventional jet mill AFG200 ). This greatly reduce the smelting costs and milling costs and milling center is entirely possible to provide even lower magnetic powder milling cost than the Nd-Fe-B manufacturers. Let us wait and see.
