2020 of the Decade of Injection Technology: China's Injection Molding Machine Technology Breakthrough

writer:LI SONG Share

The wide application of plastics in automobiles, home appliances, packaging, medicine and other fields has driven the rapid development of the injection molding industry. At present, China's injection machine industry is gradually shifting from its quantitative and price advantages in previous years to technological and innovative advantages. Following innovative technologies such as optical disc drives, two-color machines, two-platen machines, and hybrid machines, China's injection molding machine manufacturing industry has been developing all-electric injection machines, micro-foam molding, multi-color injection molding, thin-wall molding, and highly intelligent control. All have made breakthrough progress.

The rapid development of China's injection molding machine industry
China's injection molding machine manufacturing industry has been developing since the 1960s and has a history of nearly 50 years. From the oldest manpower manual injection molding machine, to hydraulic manual, semi-automatic, and fully automatic, to oil-electric composite, to today's all-electric injection molding machine, China's injection molding machine industry has achieved rapid development. Nowadays, China has production of different varieties from general injection molding machines, precision injection molding machines to special injection molding machines, and it occupies a pivotal position in the global injection manufacturing industry.

Injection Molding Machine
General injection machines are the largest product in plastic equipment made in China, mainly used for processing thermoplastic materials. China's general injection machine has many relative advantages: strong adaptability to raw materials; configuration parts such as hydraulics, electrical control parts, etc. are purchased globally, and maintenance is convenient; the delivery period is short, and the delivery period of injection machines above 10,000 grams is 3 to 6 months ; The price is low, 1/4 to 1/6 of the average price of imported equipment. It can provide a series of products of various specifications with clamping force of 200KN~36000KN to the market. It not only meets the domestic production needs of plastic parts such as automobiles, home appliances, transportation, electronic information, construction and daily necessities, but is also the most important product for China's plastic machinery exports. In recent years, the export volume has been around 10,000 units.

Precision injection machine manufacturing started late in China and is the main type of plastic machinery imported by China, with an annual import volume of thousands of units. The two-platen full hydraulic precision injection machine and the hybrid precision injection machine made in China have achieved good development in recent years. For example, the two-plate injection machine of Guangdong Hongli Machinery Co., Ltd. has registered invention patents in developed countries such as Europe, the United States, and Japan. Currently, it can provide a series of products with a clamping force of less than 8000KN. The plastic products it produces include digital discs, 1‰ Trace plastic parts above gram. The all-electric injection machine was developed in China at the end of the last century and is currently in the stage of promotion and improvement. In the past two years, the all-electric injection machine developed by Haitian has gradually been accepted by more and more markets and has become an important aspect of China's injection molding machine manufacturing technology breakthrough.

From the perspective of product output, the output of China's injection molding machines was 18,109 in 1995, 29,331 in 2000, and an average annual growth rate of 11.40% during the five-year period from 1996 to 2000; the output in 2004 reached 61,479, and in 2000 The average annual growth rate in the next 4 years reached 21.08%. From 2005 to 2006, there was also a double-digit rapid growth.

The added value of export products is gradually increasing
Chinese presses were never known abroad to "Made in China" all over the world, only a few years. In recent years, the world's plastic machinery sales have averaged 20 billion euros per year, of which Germany accounted for 30%, Italy accounted for 20%, and China accounted for about 10% (7%). However, the export value of Chinese equipment is developing rapidly. Since the export exceeded 100 million U.S. dollars in 1998, it has grown at an average annual growth rate of about 40%. In 2005, it exceeded 1 billion U.S. dollars and reached 1.33 billion U.S. dollars.

From the perspective of China's exports of injection machine products, the average annual growth rate from 2002 to 2006 exceeded 20%. At the same time, we can see that the growth rate of the export value of equipment has exceeded the growth rate of the export volume in recent years, which shows that the added value of export products is gradually increasing.

On the other hand, it can be seen from the characteristics of China's plastic machinery export regions that the export market of China's plastic machinery is gradually shifting to developed regions. The main markets that China's presses faced during the initial export were Asian, African and Latin American developing countries or regions. In recent years, they are gradually turning to developed or more developed or more developed countries or regions such as Europe, the United States, and Japan. In 2003, exports to developed or more developed countries or regions accounted for more than 60%. In 2005, exports to 9 countries or regions including Hong Kong, Japan, the United States, Taiwan, Russia, New Zealand, Germany, Italy, and South Korea reached US$680 million, accounting for 51.45% of the total export value that year. From 2002 to 2005, the average annual growth rate of the export value of these 9 countries or regions was about 45%, indicating that the market of Chinese presses in developed or more developed countries or regions is growing rapidly.

Prospects of China's injection molding machine market
With the rapid development of China's injection molding machine market and the continuous emergence of innovative technologies, China's injection molding machine's position in the global plastics machine industry is constantly improving.

The huge market, low production cost and good investment environment have made the world's manufacturing industry gradually transfer to China. At the same time, the transfer of the world's manufacturing industry will continue to drive the overall improvement of China's injection molding industry. In a certain period of time, compared with the high-cost production in other countries, low cost will be the relative advantage of China's plastic machinery manufacturing industry, among which labor cost advantage is a big factor. These will help to further enhance the overall competitiveness of China's injection molding machine industry.

While we are pleased with the new progress made in China's injection molding machine industry, we must also realize that actively developing high value-added injection molding machines and making them the main force for application and export in the Chinese market is the transformation of China's injection molding machine industry from a major injection country. It is an inevitable requirement of injecting powerful countries.
