In recent years, significant advancements in technology have propelled the development of injection molding machines, particularly in the realm of large-scale two-platen and fully electric systems. This progress has narrowed the technological gap with developed countries. Innovations include the research and industrialization of eco-friendly and intelligent pure two-plate plastic injection molding equipment, which has begun to challenge the longstanding dominance of Germany and Japan. Additionally, systems for the online processing of solid waste polymer materials have been introduced to lower energy consumption and enhance economic efficiency. Integrated intelligent production systems are also emerging, catering to end-use applications and facilitating unmanned production lines in injection molding.
Looking ahead, the domestic injection molding equipment sector must focus on the following areas:
1. High-Precision and Stability:
There is a need to develop and industrialize injection molding systems that deliver high precision, stability, and adaptability for complex applications. This includes fully automated, non-contact molding systems for medical uses and other high-purity requirements, as well as precision injection systems for engineering plastics used in 5G technologies. Additionally, fully automated systems for the automotive industry and full-electric molding machines for high-precision applications in electronics and electrical appliances should be prioritized.
2. Expandable Systems for Composite Molding:
Developing expandable injection molding systems capable of meeting the demands of composite molding is essential. These systems should focus on achieving high efficiency and precision in both molding and processing.
3. Specialized Molding Equipment:
The creation of specialized injection molding machines for advanced engineering plastics such as PEEK, PI, and PPS is crucial. These machines would serve high-performance applications, including those in electronics, aerospace, and information technology.
4. Advanced Injection Molding Processes:
High-performance injection molding systems should integrate various advanced processes. Examples include high-capacity, high-speed hot runner bottle blank machines, microcellular foam molding equipment, custom multilayer composite injection machines, thermoplastic fiber-reinforced composite systems, screwless ultrasonic plasticizing micro injection molding machines, and one-step injection molding machines equipped with automatic clamp force compensation. Additionally, intelligent integrated manufacturing systems, such as 3D photocopiers, should be developed.
5. Precision Optical Lens Molding:
High-precision injection molding machines designed for optical lenses must meet stringent accuracy and stability standards. These machines find applications in mobile phones, automobiles, security systems, and other imaging technologies.
6. Intelligent TPE Molding Machines:
The intelligent TPE corner joint molding machines, primarily utilized in automotive sealing systems, aim to reinforce the industry leadership of C-type injection molding machines.
7. Energy-Saving and Eco-Friendly Solutions:
Developing energy-efficient and environmentally friendly molding machines is vital. This includes technologies for the online configuration of recycled plastics and the remanufacturing of green injection molding equipment.
By focusing on these areas, the injection molding industry can continue to advance, ensuring high standards of precision, efficiency, and sustainability.
