From March 20 to 22, 2026, the Tianjin Plastics Industry Expo was grandly held at the Meijiang Convention and Exhibition Center in Tianjin. As an injection molding machine research and manufacturing enterprise rooted in Baodi, Tianjin, Tianjin Yihe Zhongwei Precision Machinery Co., Ltd. (Booth No.: N2-T01) made a remarkable appearance with its fifth-generation three core models—the general servo injection molding machine, the high-speed precision injection molding machine, and the two-plate injection molding machine—comprehensively showcasing its injection molding solutions for different application scenarios.

At this exhibition, Yihe Zhongwei showcased three fifth-generation flagship models, covering the three mainstream categories of high-speed machines, standard machines, and two-platen machines. They meet core requirements such as energy efficiency, high performance, and precision, and are suitable for various industry scenarios. Each model embodies our technological accumulation and innovative breakthroughs. Visitors can observe live machine demonstrations up close and experience the equipment’s performance and key advantages.

VD660BU5 Fifth-Generation Two-Platen Injection Molding Machine

Designed for deep-cavity products such as lubricant barrels, automotive plastic components, and large home appliances, the VD Series two-platen injection molding machines are the preferred choice due to their extra-large mold opening stroke, uniform clamping force distribution, and compact footprint.

The Yihe Zhongwei two-platen machines feature an advanced two-platen clamping structure combined with precise hydraulic control, ensuring stable and reliable clamping and high platen parallelism, making them particularly suitable for complex products requiring high mold accuracy. Additionally, their energy-saving design and modular configuration meet diverse production needs for large-scale products.

High Efficiency and Space Saving: Equipped with an intelligent mold opening and closing system and synchronized brake structure, effectively shortening the product molding cycle; the compact and reasonable overall machine design.

Precision Plastication: Standard with a dedicated long-barrel high-ratio screw for more uniform plastication and significantly reduced molding cycles; paired with a linear guide support structure, greatly enhancing injection accuracy.

Stability and Energy Saving: Standard with an electric material feeding device and detachable infrared heating ring, comprehensively improving overall machine energy efficiency; using an independent oil circuit filtration system, providing excellent cooling performance.

VG420BA5 Fifth-Generation Standard Servo Injection Molding Machine

The VG series VG420BA5 balances stability and practicality, making it an optimal choice for general-purpose injection molding production. It is adaptable to various conventional injection molding scenarios, features rapid machine response and high repeatability, while reducing oil temperature and noise. It is an ideal option for enterprises aiming to achieve green production and lower operational costs.

Stable and Reliable: It adopts a high-rigidity platen structure and dual-pressure center design, ensuring structural stability. The entire series comes standard with T-slot platens, facilitating mold installation and removal, and improving operational efficiency.

Energy-Saving and Precise: It uses a new barrel cooling structure and a detachable infrared heating ring, providing excellent heating and insulation performance. Coupled with a linear guide support structure, it reduces movement friction resistance and enhances injection precision.

Efficient and Energy-Saving: The optimized five-point elbow structure ensures smooth operation and rapid response, significantly shortening the dry cycle time.

This debut at the Tianjin Plastics Machinery Exhibition serves not only as a platform for Yihe Zhongwei to showcase its core technologies and high-quality products, but also as an opportunity to communicate, learn, and collaborate with peers in the industry.
