It is understood that the modern mold industry is a technology- and capital-intensive industry. In recent years, the pace of structural adjustment in my country's mold industry has accelerated, mainly because the development speed of large, precise, complex, long-life molds and mold standard parts is higher than the overall development speed of the industry; the proportion of plastic molds and die-casting molds has increased; market-oriented professional The number and capacity of mold manufacturers increased rapidly. With the deepening of economic system reform, "three foreign capitals" and private enterprises have developed rapidly. According to the statistics of the National Bureau of Statistics by the end of 2006, there were 1,314 enterprises above designated size in China's mold manufacturing industry, with 244,155 employees; the total industrial output value was 55.561 billion bald. Realized sales revenue and profit of 53.958 billion yuan and 4.675 billion yuan; exports of 1 billion US dollars. Imports of 1.47 billion US dollars.

The mold industry is developing day by day, and the mold is becoming larger and larger, which is determined by the requirement of high production efficiency. The "one-mode multi-cavity" technology developed to improve production efficiency is waiting for more and more widespread applications. Obviously, the same injection molding process can produce multiple products at the same time, and the production efficiency is naturally doubled. Another reason is that the parts are becoming larger and larger, which directly leads to the need for larger molds.

How to get rid of the trouble of mold enlargement

With the increasing size of molds and parts, we are all troubled by how to meet the increasingly high surface accuracy requirements of large molds and parts? How to prolong the service life of these large molds and components, while taking into account the comprehensive requirements of wear resistance, corrosion resistance, high hardness, etc.?

To successfully break through this bottleneck, we must break through the troubles of talents, technology and funds. Enterprises need to invest in new high-precision CNC equipment. However, these devices often require millions of dollars of investment, and the payback period is generally more than 5 years. Since most of the mold industry is a single-piece operation and the process is complicated, the scale of the enterprise is generally relatively small, and the follow-up capital investment is relatively difficult. According to the relevant person of Ningbo Shuanglin Group, taking 1 million yuan to purchase a mold processing equipment as an example, in the first five years, 90% is the cost, and only 10% of the income will generate greater profits after five years. However, due to the large wear and tear of processing equipment, general mold enterprises are reluctant to invest, which also hinders the technological progress of enterprises.

Talent is also a major bottleneck that plagues the mold industry. At present, most of the mold industry adopts numerical control technology, which has high requirements on the quality of operators, and the training of talents in the mold industry generally requires more than 5 years of experience accumulation. The total is less.

The mold industry has begun to develop in the direction of large-scale, high-precision, multi-functional composite type, etc., the application of mold standard parts will become more and more extensive, the proportion of plastic molds will continue to increase, and the technical content of molds will need to be improved.
