The mold parts industry in China is not only large-scale, but also increasingly sophisticated. The proportion of high-level molds represented by large, precise, complex, and long-life molds has reached over 35%, such as the production of B-grade vehicle complete vehicle molds for automotive cover parts;
Precision molds
The machining accuracy has reached 0.5 micrometers; Precision progressive molds can be used on high-speed punching machines with a frequency of over 2000-2500 cycles per minute; The precision of plastic molds has reached the micrometer level, meeting the needs of the development of the IT industry; A single set of tire flexible molds with a weight of 120T and a diameter of 4 meters has become a sensitive word type mold. According to Luo Baihui, CEO of Mold Network and Deputy Secretary General of Shenzhen Mold Technology Society, since 1997, with the rapid growth of the automotive, equipment manufacturing, and household appliances industries, the demand for molds in China's domestic market has begun to significantly increase. By 2009, the sales revenue of Chinese mold enterprises had exceeded 100 billion yuan, with domestic stamping and die-casting molds accounting for about 80% of the total. Many foreign enterprises have also entered the Chinese market to share this market, and their market strength is very rapid and the speed is also very fast. This is also due to the high-speed development of the Chinese economy, including the financial crisis, which has been affected to some extent, but the relatively small impact is still maintained at a growth rate of over 15%. A small number of foreign mold enterprises that have entered China have started producing various high-precision and multi-functional molds. The potential of the Chinese mold market is enormous, and high-quality stamping molds are in short supply in industries such as automotive vehicles, IT electronics, building materials and hardware; The demand for die-casting molds has surged in industries such as automotive parts and equipment manufacturing; Injection mold construction has great development potential in household appliances and other industries; In addition, special molds also have great development prospects.
