Smart Molding International 1-2023

33 www.smart-molding.com machinery accuracy of mold opening and closing is able to up to ±0.3mm and two injection units with a maximum shot weight of 140 kg. Meanwhile, it can be used in one-step molding of large- sized transparent plastic parts (or with metal inserts) with high requirement in part shape, light transmittance and accuracy, solving the molding difficulties of large-sized transparent plastic part in China. Besides, the machine incorporates cu t t i ng - edge t e chno l og i e s i n the industry, including injection compressionmolding (ICM) technology, SmartClamp technology, internal circulation two-platen clamping unit and closed-loop pump technology special for optical products. The control system integrates smart control technology, information technology and Internet technology independently developed by YIZUMI. And the machine is of high precision, high speed and intelligence, energy saving attained 30% compared with traditional three-platen machine. In February 2023, China Plastic Machinery Industry Association (CPMIA) recognized that the technology of 8500-ton InjectionMolding Machine reached the international advanced level and agreed to pass the appraisal. With the rapid development of domestic aerospace and automobile industry, the demand for ultra-large injection molding products is gradually increasing. YIZUMI will continually develop new products, new technology and new process, to improve the integrated solution for ultra-large injection parts. One-step molding of large plastic components achieved by integrating different in-mold technologies, replacing the assembling production of small and medium size plastic parts, will gradually become a new technical trend. At present, the machine which was completed prototype development and commissioning has been delivered to customer. For this achievement, Deputy Managing Director of YIZUMI Group & General Manager of Injection Molding Machine Division, Zhang Tao introduced: “The R&D of the 8500- ton ultra-large high precision injection molding machine has taken a leading role in the development of large-scale injection molding machine for the plastic industry. In terms of tonnage and injection weight, this machine is the largest injection molding machine produced in China at present.” “This machine is not only large, but alsowe have adopted new technologies such as injection compression molding process and synchronous plasticization by two injection units.” Zhang Tao emphasized, “The development of the machine has increased more possibilities for our application in large plastic parts. It also means that YIZUMI has achieved the leading position in the industry of ultra-large injection molding machines in global.” As the first product of injection molding machine with the largest clamping force in China, 8500-ton ultra-large injection molding machine can meet the demand for ultra-large products in aerospace, automotive industry, petrochemical pipeline, transportation facilities and other fields. Meanwhile, it has solved a series of difficulties in the processing, transportation and assembly of ultra-large equipment, and provided customers with more cost-effective ultra-large transparent plastic molding solutions.
