When a failure of the hydraulic press cannot rise, it usually manifests as if the pressure-regulating handwheel is fully tight, the pressure can only rise to a certain value and cannot continue to rise, especially when the oil temperature is high, which is particularly obvious. So what are the reasons for the pressure not rise? 1. Check whether the cartridge valve and the reversing valve are stuck 2. Check the circuit failure, which may be the main reason for the inability to rise under normal circumstances. It is recommended to use a screwdriver to stab the small reversing valve to see if it is stuck, and then check whether the indicator light of the rising small valve is on. 3. The main relief valve in the four-column press system is worn seriously, causing overflow and debris, which is why it is stuck. 4. The flush valve on the upper part of the oil cylinder is not opened, so it cannot rise under normal circumstances. 5. Check whether the oil cylinder is broken. 6. Whether the four-column press system is adjusted and balanced and stuck the beam, of course, there are not many such problems. 7. Total pump flow

Thanksgiving comes, and we open a new chapter together - Our company debuts at the first Shanxi (Dingxiang) Flange Forging Industry Expo in July, and the forging industry is in full swing. The grand opening of the first Shanxi (Dingxiang) Flange Forging Industry Expo not only sets up a new platform for exchanges and cooperation for the industry, but also gives us the honor to gather at the booth with the leaders of the Shanxi Provincial Department of Commerce, the Dingxiang County People's Government and the Hubei Forging Association, draw strength to forge ahead through careful guidance and anchor the development direction in in-depth exchanges. This trust and affirmation is not only a recognition of our deep cultivation and forging of strength in the field, but also an expectation for us to take root in Shanxi and serve regional industrial upgrading. As active participants in the first expo, we are well aware of the milestone significance of this grand event - it is not only a concentrated display of the industrial heritage of Dingxiang' 'China's Forging Hometown' but also an important signal for Shanxi's forging industry to move towards high-quality development. From displaying technical achievements at the booth to the same as the industry

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.

On April 3, our company was honored to welcome the on-site inspection and investigation by Hubei leaders. This inspection not only demonstrates the high attention of local governments to enterprise development, but also builds an important platform for in-depth exchanges between the two sides in industry development and regional economic construction.

On February 24, 2025, the 5,000-ton large ultra-high pressure wire winding hydraulic press developed by the company has been successfully assembled and successfully launched. The successful delivery of this equipment marks another major breakthrough for the company in the field of hydraulic technology.

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.
