Dongguan Xinyi has made a breakthrough in this key technology concerning the digital transformation of the rubber and plastic industry!

　　In 2021, the project "Research and Application of Key Technologies for Supporting Equipment and Systems of Intelligent Injection Molding Factories" jointly developed by Dongguan Xinyi Electric Heating Machinery Co., Ltd. and Dongguan Technician College was appraised by the Guangdong Mechanical Engineering Society, and the overall technology reached the international advanced level. The project lasted for four years and developed an intelligent injection molding factory solution with independent intellectual property rights, providing core technical support for the digital transformation of the rubber and plastic industry.

　　Injection molding is a method for shaping industrial products. Injection molding equipment is an important pillar of China's manufacturing industry and is widely used in consumer electronics, transportation and other fields, with a market size exceeding 50 billion yuan. However, traditional injection molding factories generally face bottlenecks such as difficult data collection, poor equipment interconnection, and high energy consumption. The rising labor costs and diversified production demands are forcing the industry to upgrade towards intelligence.

　　In 2017, to break through the problems of "information silos" and "automation disconnection", Dongguan Xinyi Electric Heating Machinery Co., Ltd. joined hands with Dongguan Technician College to launch a research and development project. Based on the demand for intelligent transformation, they created an intelligent injection molding factory integrating raw material processing, intelligent water supply, automated mechanical arms and data management systems. Strive to achieve self-perception, self-decision-making and efficient collaboration in the production process.

　　The project is led by Wu Junrui, the group general manager of Dongguan Xinyi Electric Heating Machinery Co., LTD., in collaboration with the team of Miao Yuchun, a senior lecturer at Dongguan Technician College, forming a research and development team that combines the technical backbone of the enterprise with the scientific research strength of the college. The enterprise provides production scenarios and engineering verification, while the college is responsible for key technology research and development and talent cultivation. It has jointly established the "Intelligent Equipment Research and Development Center" and the "Technician Workstation", and has cumulatively cultivated over 200 skilled talents in the field of intelligent manufacturing, achieving a closed loop of "research and development - application - education".

　　The project team spent four years dedicated to research and development. In response to the common industry problem that plastic auxiliary machines cannot be uniformly monitored, the team pioneered a "standardized communication protocol + modular control" solution, achieving real-time data collection and centralized control of equipment such as dehumidification dryers and feeding conveyors. Most importantly, the team led the drafting of the national standard "Communication Protocol for Peripheral Equipment of Rubber and Plastic Machinery", filling the gap in domestic industry standards.

　　At present, the project has formed a trinity innovation system of "hardware + software + standards" : 6 invention patents have been applied for (1 has been authorized), 9 utility model patents and 11 software Copyrights. The implementation and application of the project have brought significant changes to traditional injection molding factories: the production end has achieved full-process digital management of orders, equipment and materials, significantly reducing manual intervention and lowering the product defect rate by 25%. On the management end, real-time energy consumption monitoring and intelligent scheduling systems help enterprises achieve "precise production", saving over 500,000 kilowatt-hours of electricity annually for a single factory.

　　As the first intelligent solution covering the entire injection molding production process in China, the project's achievements not only broke the monopoly of foreign enterprises in the high-end auxiliary machine field, but also lowered the threshold for industry intelligence through "standardization + modularization" design.

　　Facing the development opportunities of Industry 4.0 and the "dual circulation", the project team plans to further deepen the application of 5G and AI technologies in smart factories, develop a production simulation system based on digital twins, and promote the upgrade of equipment interconnection from "local area network" to "cloud".
