Discuss in detail the major development trends of the injection molding industry
The high-quality development of the world's manufacturing industry will become an important theme. Promoting technological innovation and digital transformation of traditional manufacturing industries represented by the production of plastics and injection molded products will be a top priority. This is the guarantee of the basic necessities of life for the whole society, and it is also the development of other industries. The basis of industrial manufacturing. In addition, in order to implement the deployment requirements of "carbon peaking" and "carbon neutrality", strengthen overall planning, explore paths and methods, and promote green and low-carbon transformation and industrial structure optimization and upgrading, the development of the injection molding industry will see the following trends.
1. Functionalization and greening of raw materials and modified materials
With the continuous implementation of carbon neutrality and carbon peaking, green production and processing technologies of plastics are receiving more and more attention. Green additives, green flame retardants, green plasticizers, etc. are being researched, promoted and used more and more. . At the same time, the use of bio-based plastics, which are widely sourced, green, low-carbon, easily degradable, and easy to recycle, is increasing and will be widely used in packaging, tableware, home furnishing, stationery, maternal and infant products, electronic information and other industries. Although the planned production lines, production capacity and output of PLA at home and abroad continue to hit new highs, they still cannot match the growth rate of the downstream market, and raw materials and modified material products have been in short supply for a long time.
2. High-end, sophisticated, intelligent and energy-saving injection molding equipment
The import volume of injection molding machines continued to decline, and the decline gradually narrowed, with a year-on-year decrease of 11% from January to December. The growth rate of export volume began to turn positive from November, with a year-on-year increase of 4% from January to December, and the export trend was better than that of imports.
In recent years, key technologies in the industry have continued to make breakthroughs, and the gap between large two-platen, all-electric injection molding machines and developed countries has continued to narrow. For example, the research and development and industrialization of green and intelligent large-scale pure two-plate plastic injection molding equipment broke the monopoly of Germany and Japan; the online processing system of solid waste polymer materials reduced energy consumption and improved economic benefits; the integration based on terminal application needs Intelligent intelligent production system to realize intelligent unmanned injection molding production line. In the future, domestic injection molding equipment still needs to work hard in the following aspects.
1. Injection molding systems with high precision, stability and scalability for high-end complex applications, such as non-contact fully automatic molding systems with high cleanliness requirements for medical applications; engineering plastic precision parts molding systems for 5G applications; automotive-oriented Large-scale fully automatic molding system; R&D and industrialization of basic systems for all-electric injection molding machines with high-precision requirements for electronic appliances, mobile communications industries, etc.
2. Develop an scalable injection molding system that meets the needs of composite material molding to achieve high-efficiency and high-precision molding processing of composite materials.
3. Develop special injection molding machines that can mold special engineering plastics, such as PEEK, PI, PPS and other high-performance special engineering plastics, to meet the needs of international application fields (such as electronic information, aviation).
4. High-performance injection molding systems combined with various advanced injection molding processes, such as large-volume high-speed hot runner preform machines, microcellular foam injection molding machines, customized touch multi-layer composite injection molding machines, thermoplastic fiber reinforced composite molding machine, screw-less ultrasonic plasticizing micro-injection molding machine, automatic clamping force compensation one-step injection molding machine, intelligent molding integrated manufacturing system (3D copy machine), etc.
5. High-precision lens optical injection molding machines that require extremely high molding accuracy and stability are used in imaging monitoring fields such as mobile phones, automobiles, and security.
6. Focus on TPE corner intelligent injection molding machines used in automotive sealing systems to consolidate the leading position of C-type injection molding machines in the industry.
7. Energy-saving and environmentally friendly injection molding machines, such as online configuration and remanufacturing of recycled plastics, green injection molding technology and equipment.
3. Product design is lightweight, concise and integrated
Many areas of injection molded products are closely related to home life, such as the field of small household appliances. There are many types of such products, with large demand, frequent updates, high requirements for personalization and customization, fierce market competition, and relatively thin profits. In order to reduce costs as much as possible and promote low-carbon and green life, the products must meet the premise of use. They tend to become lighter and lighter, reducing the use of metal and plastic, which has begun to be reflected in structural design and mold manufacturing. At the same time, in order to meet the market demand for multiple varieties and small batches, many production links in factories have gradually become automated and intelligent. However, product assembly lines still rely on a large number of manpower, which is not conducive to improving the competitiveness of enterprises and products. To solve the problem of low assembly efficiency, an important idea is to standardize, unify, simplify, or even integrate injection molded parts to reduce the use of drilling holes and screws, thereby simplifying the assembly steps.
4. Digitalization, networking, and intelligence in production, management, and decision-making methods
Injection molding companies improve quality (product quality, service quality), reduce costs (raw material procurement costs, inventory costs, personnel costs, production costs, management costs, service costs, etc.), and increase efficiency (production efficiency, communication efficiency, collaboration efficiency, etc.), It is the main purpose of promoting intelligent manufacturing and digital transformation in traditional manufacturing industries. It is also an important magic weapon to gain a foothold in the fierce market competition and reshape development momentum and advantages. With the help of the new generation of information technology and the industrial Internet, injection molding companies will gradually optimize the allocation of resources, improve total factor productivity, and realize business through new manufacturing models such as intelligent production, digital management, networked collaboration, personalized customization, and service-oriented extension. Deep transformation and reconstruction of management and business models.
5. Technological innovation and industrial development are coordinated, clustered and ecological
China attaches great importance to key technological innovation, advocates returning to the source of innovation, breaks through a series of stuck technologies, and completely breaks the blockade of foreign technologies. In the field of injection molding industry, continuous breakthroughs are needed in the synthesis technology, production technology and modification technology of high-performance raw materials, the software and hardware technology of plastic machine equipment and accessories, the manufacturing technology and software technology of high-end equipment, etc. According to documents issued by relevant national and local departments in recent years, innovation is the main driving force of development, of which technological innovation is the core. The subjects and methods of innovation will be more diversified. In addition to some traditional research institutes and key laboratories, there will also be Various innovation centers, innovation service complexes, innovation communities, industrial development consortiums, etc. have emerged. At the same time, the efficiency and quality of technological innovation have been accelerated with the help of networking and software. The main body of innovation has been enriched through platformization and collaboration, so as to fully draw on the strengths of others and work together. Create and share. At the same time, the development of the industry is gradually moving from traditional agglomerations to cluster development. The majority of small and medium-sized injection molding companies rely on the advantages of clusters and make full use of the Internet + manufacturing industry to continuously build, strengthen and replenish chains, build an ecological system for industrial development, and truly form a Chinese characteristics and advantages. It is not difficult to see from this that future collaboration is not limited to collaboration between departments within the enterprise, collaboration between upstream and downstream of the industrial chain, but also collaboration between individuals and platforms, collaboration between enterprises and platforms, and collaboration between platforms. At the same time, the model of companies working alone will go further and further. They need to establish their own ecological partners, and corporate development will also become ecological or integrate into the ecosystem.
