Day One On-Site | Intelligence Leads, Shaping Excellence —WELLTEC Debuts at CHINAPLAS 2026

On April 21, 2026, CHINAPLAS 2026 International Trade Fair for Plastics and Rubber officially opened at the National Exhibition and Convention Center (Shanghai). Donghua Machinery made its appearance under the theme “Intelligence Leads, Shaping Excellence,” showcasing its latest achievements in intelligent manufacturing, with a focus on high-end equipment, digital management, and intelligent interaction. On the first day of the exhibition, the booth attracted numerous industry professionals and technical experts, creating a vibrant atmosphere on site.

At this exhibition, Donghua Machinery not only brought multiple core equipment tailored for specific fields, but also simultaneously showcased software platforms and intelligent interactive applications based on data-driven approaches. Through integrated solutions combining hardware and software, Donghua Machinery further demonstrated its systematic layout in the field of intelligent manufacturing, from the equipment end to the management end.

The exhibition core area features fully automated production lines and real-time data dashboards, forming the "Intelligent Manufacturing Matrix" of Donghua Machinery, directly addressing key industry pain points through on-site production data.

In response to the core demand for rapid mass production in the food packaging industry, the 450PET-HS system has become the undeniable focus on site. This system deeply integrates a new generation of PET-specific injection molding machines with a high-speed side-pick multi-station embryo retrieval device, with the control unit seamlessly embedded, achieving efficient coordination of the entire line. During the on-site demonstration, the molding cycle for a single mold with 96 cavities was stably maintained under 9 seconds, translating to a daily production capacity exceeding 12 tons. Meanwhile, the0.16kW·h/kg40% technology seems to be a mistranslation. The correct translation should be "the servo and hot runner linkage technology," which I will include in the final translation.

Meanwhile, the servo and hot runner linkage technology strictly controls the overall production energy consumption to 0.16 kW·h/kg, achieving an energy-saving improvement of about 40% compared to traditional models, and striking a practical and reliable balance between production and energy efficiency.

650HD-PP Dedicated Preform Machine for Infusion Bottles

Specifically designed for medical and high-end packaging applications, the 650HD-PP IV bottle preform injection molding machine is showcased simultaneously. This model achieves a shot control accuracy and mold opening/closing position repeatability of 0.01 mm, and a product weight repeatability as high as 2‰, thereby better meeting the stringent requirements of high-cleanliness environments. Its extra-large tie-bar spacing and pull-out tie-bar design provide ample space for large mold installation and rapid mold change. Additionally, it delivers over 25% energy savings, low vibration, low noise, and supports 24-hour continuous, stable production—fully compliant with cleanroom requirements in medical facilities.

In the daily goods industry, the 130PS sandwich injection solution demonstrated on-site the dual-material sandwich injection process. By filling the core layer with low-cost or high-strength materials and coating the outer layer with high-quality materials, this composite approach ensures the appearance and structural performance of the product while effectively reducing the overall material cost, providing a new idea for enterprises to reduce costs.

Behind the orderly operation of the hardware production line, a large display screen at the booth presents the real-time operational overview of the iSee 4.0 Intelligent Management Cloud Platform. As a Huawei Cloud IoT partner, iSee 4.0—a smart MES platform—continuously collects and professionally processes production big data from on-site equipment, enabling real-time monitoring and analysis of production progress, product quality, and equipment energy consumption. More importantly, the high-quality data assets it steadily accumulates lay a solid foundation for the deeper implementation of machine learning and artificial intelligence applications.

The enthusiastic response at the Shanghai exhibition is just a microcosm of Donghua Machinery's intelligent manufacturing layout. The simultaneous opening day of the Wuxi East China production base will showcase real-world solutions covering a wider range of specialized fields. We sincerely invite all industry colleagues to visit the site for exchanges and to more intuitively experience the complete results of Donghua Machinery from technological demonstrations to practical implementations.
