The fast rising of the labor costs has given rise to China's growing demand for industrial robots, which will also bring opportunities to the development of dynamic core neodymium magnet material of industrial robot.
According to historical data, China’s application ratio of robots in the industrial field is relatively low, leaving much room for growth in the future. Today, China's industrial robots use density is still lower than the global average, and substantially left behind by Japan, Korea, and Germany. South Korea’s use density of industrial robots is the world's highest one, with average of 395 units in per 10 thousand workers, while that in Japan and Germany were 339 units and 274 units, and only 23 units in China, less than half of the international average of 58 units. In 2012, the number of China's manufacturing workers were 42 million 620 thousand, if calculated according to the international average of 58 units, there shall be 247 thousand robots; if the avocation of 100 units per worker by the Ministry is implemented, China's industrial robots volume would reach 426 thousand units.
According to the 2014-2019 China neodymium iron boron permanent magnet material industry market analysis and investment forecast report released by CINIC, at present, the price of a 165kgs welding robot is about $168.6 thousand yuan (foreign) to 29.9 million yuan (domestic). The cost of the servo motor in it accounts for about 15%, i.e. 25.4 thousand yuan (foreign) to 42.8 thousand yuan (domestic). According to public information, the cost of neodymium magnets in the permanent magnet synchronous servo motor takes approximately 20%. Based on such percentage, NdFeB material cost is about 5095 yuan (foreign) to 8563 yuan (domestic). Currently, the raw material price of NdFeB N35SH is about 220 yuan / kg, which means the consumption of NdFeB is about 23 kgs (foreign) to 39 kgs (domestic). Taking into account the high gross profits of imported servo motor used in domestic robots, we believe that 25kgs of high-performance neodymium magnets will be consumed for one single 165kg welding robot. According to the International federation of robotics statistics, the current growth rate of global industrial robots is about 27%. Industrial robot sales have increased in all major global markets, among which China market grew by more than a half.
Meanwhile, with the rapid development of “internet + manufacture”, Industry 4.0 possibly will enter into Chinese manufacturing with Industry 3.0. The growing space of robot and automatic technology is vast. Policy support and industrial investment become important driving factors. Organizations expect that the demand of industrial robot is 63-170 sets from 2015 to 2020. Especially automobile areas, which cover 60% of the application of industrial robot, hopefully will development dramatically in the future. Development of China’s robot industry also brings better opportunity to application expansion of neodymium permanent magnet industry.
