In recent years, the product structure adjustment of die and mold industry has been accelerated. The technology content of large-scale, precision, complex and long-life mold is relatively high. The development speed of mold is higher than the overall development speed of the industry, accounting for about 35% of the total mold amount.
At present, China's total production of stamping parts processing dies has been ranked in the forefront of the world, and began to gradually change from a mold import country to a mold export country. There are more than 30000 mold manufacturing enterprises in China, with about 1 million employees. In 2012, the sales volume was 124 billion yuan, and the production and sales were booming. The output, quality and level were further improved, especially the development of automobile manufacturing industry and it manufacturing industry, which promoted the improvement of mold grade. Excellent mold manufacturing equipment provided guarantee for the improvement of mold technology level. China's mold industry is going through the 'golden development stage', and will continue to grow rapidly in the future.
From the perspective of industry structure, private enterprises have developed rapidly, state-owned enterprises have become more active, the number and capacity of market-oriented professional mold manufacturers have increased rapidly, the cluster production Park of stamping parts processing dies adapted to the production characteristics of the mold industry has been developed, and the less developed areas such as the central and western regions of the mold industry have made great progress.
The precision of multi position progressive die in some stamping die enterprises has reached 2 μ m, and its service life can reach more than 300 million punches. The multi position progressive die of some enterprises can be used on the high-speed punch press with 2500 times / min, and the precision can reach 1 μ M. It has been able to produce 43 inch large screen color TV, 65 inch rear projection TV plastic shell mold, 10 kg large capacity washing machine complete set of plastic parts mold, automobile bumper, integral instrument panel and other large plastic mold.
Precision plastic stamping parts processing mold has been able to produce camera and mobile phone plastic parts mold, multi cavity small module gear.
