On June 15, Zhejiang Province Science and Technology Award Conference was held in Hangzhou. The 2020 Zhejiang Science and Technology Award, Natural Science Award, Technological Invention Award, Science and Technology Progress Award and International Science and Technology Cooperation Award were awarded at the conference site to commend outstanding contributors in the province’s science and technology field. Among them, the R&D project of Tederic Machinery Co., Ltd. “R&D and industrialization of injection molding process and equipment for large Complex Optical Grade Parts” won the first Science and Technology Progress Award of Zhejiang Province.
As a heavy weight event in science, several awards presented at the conference represent the highest honor in the field of science and technology in Zhejiang Province. They are not only a concentrated display of the province’s major landmark achievements in scientific and technological innovation, but also a symbol of the “weathervane” of cutting-edge technology . In this project, the large-scale and complex optical-grade parts molding equipment ,developed by Tederic has conducted joint research on key technologies such as independent precision control of large-scale injection molding equipment, large-scale optical-grade parts molding technology and complete sets of equipment, and achieved a series of significant results.
Tederic has adopted three major technical highlights: “High-precision dual-loop control method for injection moulding systems”, “Multi-directional synergistic multi-layer integral injection and secondary mould closing process”, “Horizontal heavy-duty turntable opposed moulding and dynamic balancing technology for mould plates “. Overcome difficulties, make breakthroughs in innovation, and have significant advantages in terms of dimensional accuracy, molding cycle, and optical characteristics. In addition, with Tederic’s Material solutions and high-end multi-component injection moulding machines, it can provide auto parts customers with overall solutions and automated production solutions, and continue to promote the development of the plastic molding equipment industry in the direction of high-end intelligence.
At present, the results of the project have been fully industrialized. In the field of auto parts, they are mainly used in optical-grade plastic parts represented by automobile lights, atmosphere lights, panoramic sunroofs, and display screens. In addition, the project is widely used by global auto parts leaders such as Röchling in Germany, and the products cover a large number of well-known car companies such as BYD, Audi, Volkswagen and Ford.

For high-end large precision manufacturing field, for a long time, due to high-end equipment and the lack of key core technologies, our country’s urgently needed such equipment has been heavily dependent on imports, relevant equipment has been included in the national “Major Technical Equipment Independent Innovation Guide Directory.”
Through key technologies, the project results have filled the gaps in the injection molding process and equipment of large and complex optical-grade parts in China, and also marked that the problem of foreign “stuck necks” in the field of high-end precision optical-grade parts has been solved , and it can completely replace imports. The first domestic 2000-ton multi-station injection molding machine developed by Tederic , after more than ten years of painstaking research and development, the main indicators have been tested by industry authoritative testing agencies to be superior to foreign countries, completely breaking the foreign monopoly, it was appraised by the appraisal committee headed by two academicians that “the overall technology has reached the international advanced level”. In addition, the equipment was rated as “Outstanding Product of Machinery Industry in the 40th Anniversary of Reform and Opening Up”.
