1. Core Positioning of Electro-Hydraulic Servo Drives
The VEIKONG VFD550I series electro-hydraulic servo drive is a professional product specifically developed for hydraulic control applications. According to the product brochure, this system consists of the VFD550I drive and the MFD series AC permanent magnet synchronous servo motor, offering core advantages such as ultra-quiet operation, over 30% energy savings, and millisecond-level pressure response. Although many people associate electro-hydraulic servo drives exclusively with injection molding machines, their application range extends far beyond this single equipment type.
2. Injection Molding Machines: The Most Mature Application
Injection molding machines represent the most common application for electro-hydraulic servo drives. According to customer cases in the brochure, the VFD550I has achieved significant results in injection molding machine retrofit projects. By replacing hardware with excellent electro-hydraulic servo control software, system response speed is accelerated, mold opening and closing accuracy is ensured, and injection end position accuracy reaches 0.1mm. The high-precision, high-response PID algorithm module makes system pressure very stable, with pressure control overshoot less than or equal to ±1% and steady-state fluctuation less than or equal to ±0.5 Bar, effectively improving plastic product molding quality. Additionally, high-speed field weakening control and high response speed increase overall machine efficiency by 10%, with year-on-year power saving reaching 35%.
3. Die-Casting Machines: A Typical Application for Multi-Pump Confluence and Diversion
Die-casting machines represent another important application area for electro-hydraulic servo drives. According to the brochure, the VFD550I series can achieve multi-pump confluence and diversion switching functions, allowing either confluent operation for the same action or diversion to complete different actions. The die-casting machine multi-pump confluence and diversion application case in the brochure shows that compared with simple multi-pump confluence systems, this system offers faster response, can complete more than two independent action processes simultaneously, significantly shortens product molding cycles, allows certain actions to be completed separately, greatly saves production time, improves production efficiency, and achieves greater energy savings.
4. Hydraulic Balers: Dual Improvement in Energy Savings and Efficiency
Hydraulic balers represent another successful application scenario for the VFD550I electro-hydraulic servo drive. According to the metal hydraulic baler application solution in the brochure, the solution using the VFD550I electro-hydraulic servo drive paired with a permanent magnet synchronous servo motor saves 20% to 60% of electricity compared with traditional hydraulic baler control solutions. The excellent control algorithm of the VFD550I hydraulic servo drive ensures that system speed follows response quickly and stably, guaranteeing accuracy of system oil pressure changes and fast, efficient single cycles during hydraulic baler operation. In this application, system single-cycle time was reduced to 96 seconds. Excellent overload capacity ensures safe and stable operation of the hydraulic baler even under extreme load conditions.
5. Hydraulic Stations: Measured Power Saving Exceeding 50%
Hydraulic stations are core components of industrial hydraulic systems and an important application area for electro-hydraulic servo drives. According to the hydraulic station application solution in the brochure, a project conducted before-and-after comparison measurements using a meter, achieving a power saving rate of 51.2% after the retrofit was completed. After completing the first phase of retrofitting 29 hydraulic stations, two subsequent phases of retrofitting were carried out. This case fully demonstrates the energy-saving value and reliability of the VFD550I electro-hydraulic servo system in large-scale hydraulic station retrofit projects.
6. Metal Hydraulic Balers and Presses
Beyond the equipment mentioned above, the VFD550I can also be applied to metal hydraulic balers, presses, and other equipment. According to the press application solution in the brochure, customers require fast response and stable pressure to ensure product quality consistency, while also achieving high efficiency and energy savings. The VFD550I achieves pressure flow response time as fast as 20ms and displacement accuracy less than 0.1mm, enabling the press to move when commanded, stop when commanded, and position precisely. At the same time, products produced have high consistency, greatly reducing the defect rate.
7. Conclusion: Broad Applicability Across Hydraulic Equipment
From injection molding machines to die-casting machines, from hydraulic balers to hydraulic stations and metal presses, the VEIKONG VFD550I series electro-hydraulic servo drive, with its dual-motor compatibility, multi-pump confluence and diversion control, millisecond-level pressure response, and excellent overload capacity, is widely applicable to various types of hydraulic equipment. Whether you need to retrofit an existing injection molding machine or seek a drive solution for a hydraulic baler or die-casting machine, the VFD550I delivers efficient, stable, and energy-saving solutions. VEIKONG will continue to serve global hydraulic equipment users with professional technology.
