In the golden autumn season, people in the plastics industry at home and abroad focused their attention on the largest exhibition venue in Asia-Guangzhou International Convention and Exhibition Center. The "7th Asia-Pacific International Rubber and Plastic Industry Exhibition" was held in Longzhong from September 9 to 12, 2004. The grand exhibition area of 42000 square meters brings together more than 600 outstanding enterprises at home and abroad, focusing on displaying new materials, new technologies, new processes and new equipment in the plastic and rubber industry. This exhibition has become a veritable industry event and a platform for the plastic and rubber industry to open up markets, strengthen cooperation and exchange information. It is understood that more than 95% of the exhibitors are plastic machinery enterprises. For this reason, HC360 Huicong plastic industry channel summarizes the development status of China's plastic machinery industry and the opportunities and challenges it faces through extensive communication with plastic machinery exhibitors.

Since the 1990 s, China's plastic machinery manufacturing industry has developed rapidly and steadily, not only in terms of quantity, but also in terms of quality. At present, China's plastic machinery manufacturing industry is in a critical period from a manufacturing power to a manufacturing power.

China has become a major producer of plastic machinery

According to data, in 2003, the total output value of China's plastic machinery industry was 12.821 billion yuan, 3.44 times that of 3.723 billion yuan in 1993, with an average annual growth rate of 13.50 percent. The sales amount was 12.206 billion yuan, 3.40 times that of 1993, with an average annual growth rate of 13.28 percent. Exports of 0.583 billion billion US dollars were 20.10 times that of 0.029 billion yuan in 1993, with an average annual growth rate of 41.57 percent, of which exports exceeded 0.1 billion US dollars for the first time in 1998 and grew by 35.85 in 2003. Exports in 2003 accounted for 37.90 per cent of total industrial output in that year.

Plastic machine manufacturing technology into the international advanced ranks

In the past ten years, China's plastic machinery manufacturing technology has accelerated, and the products have made breakthroughs in the main comprehensive economic and technical indicators (including temperature control accuracy, energy consumption per unit weight of raw materials, plastic molding accuracy and machine production efficiency). At present, the plastic machinery manufacturing technology of some enterprises in China has entered the international advanced ranks. Generally speaking, the domestic plastic machinery manufacturing technology has been close to the international advanced level.

Among them, the advanced degree of the main comprehensive economic and technical indicators is closely related to the equipment, and is related to each configuration technology of the equipment production line. These indicators affect the market competitiveness of energy saving, material saving and products, and are the necessary conditions for users to maximize the benefits of equipment manufacturing.

Temperature control accuracy: before the mid-1980s, the temperature control accuracy of domestic equipment was ± ℃, and it was ± 3 ℃ in the mid-1990s. At present, it has generally reached ± 1 ℃, and some advanced enterprises have reached ± 0.5 ℃, which is on the same level as today's international advanced technology.

Energy consumption per unit weight of plastic molding: At present, the energy consumption of domestic equipment is basically the same as that of international advanced equipment. For example, the processing of multi-layer co-extrusion blow molding film production lines including PA, EVOH and other high barrier materials, the current international advanced level of plastic molding energy consumption is about 0.4kw/kg, while the similar equipment manufactured by Guangdong Jinming Plastic Equipment Co., Ltd. has reached 0.3~0.37kw/kg.

Plastic molding precision: improve plastic molding precision, not only means the quality of plastic products, but also means to save raw materials, reduce production costs. In terms of molding accuracy, there is still a certain gap between domestic equipment and international advanced level. However, in recent years, more and more enterprises in China have manufactured equipment molding accuracy into the international advanced ranks. Such as the international advanced equipment production of 0.015~0.2mm co-extrusion blown film, the thickness accuracy of ± 5%; Guangdong Jinming Plastic Equipment Co., Ltd. manufacturing similar equipment, film thickness accuracy has reached ± 3 ~ 4%.

Production efficiency of the machine: high speed, high efficiency and high capacity are the development trend of international plastic machinery manufacturing in recent years. For example, when the empty cycle time of small precision injection machine is less than 2 seconds and the maximum plasticizing capacity of single screw extruder with screw diameter of 45mm is more than 200kg. China has also achieved remarkable results in improving the efficiency of mechanical production.

The market is vast, with domestic foreign-funded enterprises and international markets becoming the focus of expansion.

Domestic three-capital enterprises. In recent years, the total amount of plastic processing in China is in a state of rapid growth and the demand for different levels, especially high-performance plastic machinery, not only provides the most important premise for the development of China's plastic machinery industry, but also caused the import equipment for many years has been at a high level and continues to grow.

Plastic machinery in the domestic market capacity, according to the number of units or production capacity, domestic equipment accounted for about, imported equipment accounted for 25%; according to the amount, imported equipment accounted for about 75%, domestic equipment accounted for 25%, and the past two years also showed a downward trend.

In 2003, 55.78 per cent of the value of imports, or $2.196 billion of equipment, was imported by foreign investors as investment. 71.44 per cent of the imported equipment (by value) went to the three-capital enterprises. This shows that the growth of domestic market capacity and foreign investment are an important factor, and it also means that domestic plastic machinery is difficult to enter the three-capital enterprises.

International market: domestic equipment is undergoing the test of the international market, but also promote the improvement of China's plastic machinery manufacturing level. China's plastic machinery batch to enter the international market only a few years of history, but the growth rate is fast. Since 2000, the amount of exports has accounted for the total output value of the industry 1/4~1/3. Therefore, increasing exports has become an important factor driving the development of China's plastics machinery industry. In recent years, the export of domestic plastic machinery not only in the number of rapid growth, but also in the export region has also undergone profound changes, from the main export to developing countries in Asia, Africa and Latin America and other developed countries or more developed countries. According to statistics, in 2003, exports to Europe, North America, Australia and Asia's Japan, South Korea, Thailand and Hong Kong and Taiwan accounted for 61.48 per cent of China's exports that year.

In short, the development of China's plastic machinery industry there is a broad market space. Domestic foreign-funded enterprises, international developed and more developed countries and regions should become the focus of domestic equipment to expand the market in the future.

Opportunities and Challenges Faced by China's Plastic Machinery Industry

After 50 years, especially the reform and opening up more than 20 years of rapid development, China's plastic machinery manufacturing has formed a high level of research, design, processing and management team, and has a more advanced equipment conditions and a more perfect domestic market and to extend the international market to expand the marketing network of the perfect industrial system, with the basic conditions of international standards.

In the late 1980 s and early 1990 s, the trend of overseas counterparts entering the mainland for the first time was mainly those from Hong Kong and Taiwan. At present, the trend of overseas counterparts entering China through sole proprietorship and cooperative enterprises is gradually forming for the second time. To improve China's plastic machinery manufacturing technology will have a positive role in promoting. This time, China is mainly entered by counterparts from developed countries, such as Baden Feld, Klaus Maffei and Coperion in Germany, Toshiba and Ube in Japan, bringing international advanced manufacturing technology. As a result, China's plastic machinery manufacturing technology in general into the international advanced ranks is not far away, China's domestic equipment all over the world will become possible.

The entry of developed countries' counterparts into China is an opportunity to improve the overall level of domestic equipment manufacturing technology. At the same time, it is a great challenge for the existing domestic enterprises in the mainland, including Hong Kong and Taiwan. Moreover, excessive competition, low prices, declining efficiency, low level of enterprise management, backward marketing concepts, lack of cohesion in the industry, and inadequate service management will be a stumbling block to improve plastic machinery manufacturing technology, which needs to be solved urgently!

In short, China's plastic machinery and international advanced technology competition, the real power to become a plastic machine, the only way is to find their own relative advantages and give full play to, in order to really become stronger, in order to have more existing domestic enterprises manufacturing technology and international advanced technology dance!
