Precision injection mould is one of the important equipment to determine the precision of injection structure, China's mould industry is huge, the number of production enterprises, most of them are small, design ability, differentiation service ability, product quality is poor, can not produce precision mould, with precision mould production capacity of the number of enterprises is less. with the increasingly fierce competition in the market, China's mold industry in the strong enterprises in the field of precision mold layout continues to deepen, can not to the precision mold field to expand business in the future of the enterprise will be eliminated risk will increase. with the transformation and upgrading of the manufacturing industry, China's precision injection molding application ratio will continue to climb, the industry has broad prospects for development. In the global market, Germany, the United States, Japan and other industrially developed countries started earlier in the field of precision manufacturing, with a longer development time and more relevant capital investment, and the level of precision injection molding technology is in the leading position. Compared with them, China's precision injection molding industry started late and underdeveloped, there is still a certain technical gap, especially in the field of high-end ultra-precision injection molded parts, China still has more room for progress.
