At present, the output value of Chinas foam machinery is about hundreds of millions of yuan, and the equipment imported each year is about hundreds of millions of dollars. The manufacturing industry of mechanical equipment is an important industry to provide technical equipment for all walks of life. In recent years, it has gradually developed into one of the pillar industries with rapid growth and vitality in Chinas national economy. However, due to the late start and the lack of concentration of technical resources, the technological innovation ability of Chinas manufacturing industry is very weak.

Now, Chinas foam machinery and equipment are not only on scale, but also accelerating toward the integration and automation of optical, mechanical and electrical. It has made great progress in packaging equipment and packaging material production equipment. However, Chinas export volume is less than 5% of the total output value, while the import volume is roughly equal to the total output value. This shows that there is a large gap in the demand for equipment in our country. Compared with foreign products, the gap in the level of science and technology is still large, far from meeting the domestic demand.

In addition, there are about ten kinds of foam machinery in China, which lack of high-precision, high-tech and high-quality supporting products. The performance of the products is low, the stability is poor, the surface treatment is rough, the shape is not beautiful, and the technical level is 20 years behind that of the advanced countries.

From the perspective of enterprise status, there are few leading enterprises in domestic foam machinery industry, and few enterprises with high technology level, high production scale and product grade reaching international level; In terms of the development of scientific research products, they are still basically in the stage of test and imitation. The ability of self-development is not strong, and the investment in scientific research is very small, accounting for only 1% of the sales volume. However, in developed countries, it is as high as 8-10%.
