The damage to the hydraulic valve parts during daily production and use of hydraulic presses is usually caused by the following reasons: 1. Deformation of physical structures due to long-term fatigue and overload. When the stress during work and external load stress during use exceed the yield strength of the part material, physical deformation of the external structure occurs, especially the bending deformation of the valve core of the overflow valve and the spring deformation, the reciprocating operation is inflexible, resulting in unstable system pressure or slow state transition process. 2. The valve core and valve body are seriously worn, and the gap is too large. The valve core and valve body (shelves), etc. are constantly friction during movement and use, causing changes in the size, shape and surface quality of the parts to change, and the quality is reduced and the effect is ineffective. The solenoid reversing valve core is worn and deformed, causing the valve to leak internally, resulting in reduced efficiency or unstable pressure, causing the system to not work normally. 3. The oil is not clean and causes the hairpin to wear, which will cause the hydraulic valve parts to not work normally, and may even cause hydraulic pressure.

Recently, good news came from relevant departments of national standardization management. Many important standards formulated by our company in-depth participation have been officially implemented, marking that our company has made a major breakthrough in the field of industry standardization construction and further consolidated its leading position in the industry. GB/T 44949 - 2024 'Intelligent Hot Stamping Forming Production Line' participating in the formulation of national standards will be officially implemented on November 28, 2024. This standard puts forward comprehensive and meticulous specifications and requirements for the planning, design, manufacturing, installation, debugging, acceptance and other aspects of the intelligent hot stamping production line, which is of great significance to improving the overall quality and reliability of the intelligent hot stamping production line and promoting the technological upgrading of the industry. With our deep technical accumulation and rich practical experience in the field of hot stamping forming technology, our company has deeply participated in the entire process of standard formulation, providing strong support for the scientificity, practicality and forward-looking nature of the standards. With this

On February 24, 2025, the 200-ton four-column hydraulic press produced by the company has been successfully loaded and is ready to be shipped to the designated location of the customer, further consolidating Wanda Machinery's technical advantages in the field of hydraulic equipment manufacturing. The successful application of this technology not only demonstrates the company's R&D strength in high-performance hydraulic equipment, but also further enhances customers' trust and support for the Wanda brand.

On March 19, 2025, Zhongshan Wanda Machinery Automation Technology Co., Ltd. (hereinafter referred to as 'Zhongshan Wanda') and Kunshan Shanxin Aluminum Co., Ltd. (hereinafter referred to as 'Kunshan Shanxin') successfully held a signing ceremony for the WDR-10000CS ultra-high pressure servo precision hot and cold forging hydraulic press. This cooperation marks an important step forward for both parties in the field of high-end hydraulic equipment and jointly promote the development of advanced manufacturing technology.

The bell of the New Year has just rang. As Vientiane is renewing, in order to further enhance the company's sustainable development momentum, Zhongshan Wanda Machinery Automation Technology Co., Ltd. actively made plans and worked hard on February 6, 2025 under the leadership of General Manager Yan Changrong. At the sales department meeting, General Manager Yan Changrong first conducted a comprehensive and detailed review of the company's sales in the past few years. He not only reviewed the sales performance growth curve every year, but also deeply analyzed the sales characteristics of each regional market and the sales performance of different product lines. Through in-depth exploration of past data, Mr. Yan has provided a solid basis and clear direction for the formulation of sales targets in 2025. He emphasized that the setting of sales targets must not only conform to the actual market situation, but also be challenging, and encourage all sales personnel to climb to the top.
