What is the demand for injection molding in 2023? China's injection molding industry has enormous development potential
injection molding is a method of industrial product production molding, typically using rubber injection molding and plastic injection molding. injection molding can also be divided into injection molding, compression molding, and die-casting. injection molded products are widely used, and the vast downstream industry provides strong support for the development of china's injection molding industry. with the introduction of the "detailed plan for revitalizing the petrochemical industry", china's injection molding industry has ushered in new development opportunities. injection molded products usually use rubber injection molding and plastic injection molding, and in 2023, various industry markets will gradually rely on injection molding technology. at present, the injection molding industry has penetrated into all aspects of life, and the demand market for injection molding is also increasing. the injection molding machine industry in china belongs to an industry strongly supported by policies for development. the national policies have created favorable conditions for the development of the industry and driven its development.
Injection molding industry research
China is a major producer of plastic products, with an apparent consumption of around 80 million tons in the plastic industry and around 60 million tons in plastic products.
The injection molding industry has a wide range of downstream applications, mainly in the fields of automobiles, home appliances, packaging, etc. According to statistics, the highest downstream proportion of injection molding machines in China is in the field of general plastics, accounting for 28%; Next is the automotive sector, accounting for 26%.
In terms of industrial layout, the East China region, South China region, and Central China region are relatively concentrated regions in China's injection molding industry, forming a group of influential industrial clusters. Under the strong promotion of national and local government policies, the construction of industrial clusters will focus on implementing strategies such as green, ecological, low-carbon, and recycling, and will extend from simple processing operations to the entire industrial chain with high technological content and high added value. In order to promote the stable, healthy, and sustainable development of the injection molding industry cluster, and further enhance the overall competitiveness of the injection molding industry.
Injection molding can manufacture products with various shapes, sizes, accuracy, and performance requirements. In the future, the proportion of the injection molding market will become increasingly high, ranging from micro gears, microelectronic components, medical micro instruments, to products such as televisions, washing machine casings, and automotive plastic parts, which will increasingly rely on injection molding technology.
Market demand in the injection molding industry
The injection molding industry has permeated every aspect of life, from ballpoint pens, toothbrushes, plastic cups, toys, home appliances, to airplanes, trains, cars, and ships. It can be said that life now cannot do without injection molding. And with the improvement of people's living standards, product updates are becoming faster and faster, and the demand in the injection molding industry is also increasing.
The main molding methods for polymer materials include extrusion molding, injection molding, blow molding, rolling molding, compression molding, etc. Among them, injection molding plays an extremely important role in the molding and processing of polymer materials due to its advantages of producing and manufacturing products with complex shapes, easy integration with computer technology, and easy implementation of automated production. Injection molding technology is widely used in various fields such as automobiles, home appliances, electronic equipment, office automation equipment, and building materials.
Analysis of injection molding industry
China's injection molding industry has enormous development potential, with nearly 85% of injection molded products requiring injection molding.
Rubber injection molding is a production method that injects rubber directly from the machine barrel into the model for vulcanization. The advantages of rubber injection molding are: although it is an intermittent operation, the molding cycle is short, the production efficiency is high, and the embryo preparation process is canceled. The labor intensity is low, and the product quality is excellent.
Plastic injection molding: Plastic injection molding is a method of plastic products that uses pressure to inject molten plastic into plastic product molds, and then cools them to form various desired plastic parts. There are mechanical injection molding machines specifically designed for injection molding. The most commonly used plastics at present are polyethylene, polypropylene, ABS, PA, polystyrene, etc.
Injection molding: The resulting shape is often the final product, and no further processing is required before installation or use as the final product. Many details, such as protrusions, ribs, and threads, can be formed in one step of injection molding.
According to the "2022-2027 China Injection Molding Industry Market Status Survey Research and Development Strategy Consultation and Prediction Report" by China Research Institute of Industry, it is analyzed that:
At present, the continuous breakthroughs in injection molding technology and the continuous growth of injection molding demand have promoted the sustainable development of the industry. The injection molding industry still has a long period of development, and the future development direction may be automation and mechanization. Now China is facing the adjustment of the entire industrial chain, so those small enterprises may become increasingly difficult to do and eliminate a group of enterprises that cannot adapt to the market. Of course, this process also comes with opportunities.
In the future, China's plastic processing and injection molding equipment will continue to improve productivity, and the automation of injection molding processing will become an inevitable trend, and the competition in the injection molding industry will also become more intense.
Import and export situation of injection molding machines
From the perspective of injection molding machine imports, the overall import volume and amount of injection molding machines in China are in a fluctuating upward trend. In 2021, the import volume of injection molding machines in China was 7762 units, a year-on-year increase of 30.5%; The import amount was 743 million US dollars, a year-on-year increase of 25.3%. In recent years, the import and export trade of domestic injection molding machines has been in a trade surplus situation. At present, the localization level of China's injection molding machine market is relatively high. From January to September 2022, the national plastic product industry produced 57.607 million tons, a year-on-year decrease of 4.2%.
From the perspective of injection molding machine exports, due to the continuous development of China's injection molding machine industry, technological breakthroughs, and increased product added value, although the export volume of injection molding machines in China has decreased in recent years, the export amount has steadily increased. In 2021, the export volume of injection molding machines in China was 49387 units, a year-on-year decrease of 31.5%; The export amount was 1.694 billion US dollars, a year-on-year increase of 39.5%.
At present, the competitiveness of domestic injection molding machine products in the high-end market is insufficient, mainly concentrated in the middle and low end areas, and there is huge room for domestic substitution in the high-end market. Leading domestic injection molding machine enterprises are making efforts to continuously improve their technical level and accelerate the layout of high-end fields. In the future, the domestic substitution process for high-end injection molding machine markets in China will continue to accelerate.
