As a leading enterprise in the domestic high and medium pressure cylinder field, “ Wantong Hydraulic ” ) relies on its technological breakthroughs and large-scale production capacity in the field of mining excavator cylinders to continuously provide the global mining machinery industry with efficient and reliable hydraulic solutions. The company takes independent innovation as its core driving force, relying on its full industrial chain layout and military-grade quality control system, becoming an indispensable “ power core ”。  

Deep Cultivation of Technology: Customized Solutions Meet Diverse Needs  

Wantong Hydraulic mining excavator cylinders cover 6T-50T tonnage range, with cylinder diameters reaching φ85-φ190 ，and piston rod size range φ45-φ135 ，maximum length 3000mm ，to meet the needs of different working conditions. Targeting the harsh working environment and large load fluctuations of mining operations, the company has developed high-strength cylinder cold drawing technology and wide temperature range high-pressure sealing technology ，through special heat treatment and surface treatment (such as laser cladding, QPQ nitriding) to improve wear resistance and corrosion resistance, the product life is improved compared to conventional cylinders 30% or more. In addition, Wantong Hydraulic provides personalized customization services, and can adjust the structural design according to customer needs, such as optimizing the buffer device to reduce impact load, or strengthening the sealing system to cope with high-dust environments.

Full-Chain Intelligent Manufacturing: Military-Grade Quality Ensures Mining Safety  

Relying on 18 square meters of production base and nearly 10,000 sets of / intelligent equipment, Wantong Hydraulic has built a closed-loop full industrial chain from raw material processing to finished product testing. The company uses IATF16949:2016 quality management system, achieving “ incoming inspection - process - finished product ” full-process digital monitoring, ensuring that the product passing rate 100% 。In mining cylinder production, Wantong Hydraulic introduces intelligent automatic production line for dump truck cylinders and surface treatment production line ，while reducing costs through economies of scale, it ensures product 35MPa stability under high-pressure conditions. 2024 In the year, the company's mining cylinders were successfully applied to the excavator transformation project of a large open-pit coal mine, with a fault rate reduction of 45% ，helping customers achieve continuous operational efficiency improvements 18%。  

Innovation-Driven: Industry-University-Research Integration Leads Industry Upgrades  

Wantong Hydraulic adheres to “ technology is the barrier ” strategy, cooperating with top universities such as Beijing Institute of Technology and Zhejiang University to establish a 71 person R&D team (including 1 academicians, 6 provincial-level and above high-level talents), focusing on the lightweight and intelligent direction of hydraulic systems. In recent years, the company has made breakthroughs in large-span load matching design technology ，developing multi-stage pressure adaptive cylinders that adapt to the complex terrain of mines, and reserving planetary roller screw and other cutting-edge technologies, laying the foundation for future electrification and mechatronics transformation. 2024 In the first half of the year, the company's net profit bucked the trend and increased by 32.87% ，with a significant increase in the proportion of revenue from mining machinery products.

Global Layout: From Domestic Benchmark to International Breakthrough  

Wantong Hydraulic's mining excavator cylinders have formed a dual-drive pattern at home and abroad. In the domestic market, its products serve leading enterprises such as Zhengzhou Coal Machinery and Shandong Energy Group, and have won the title of outstanding contribution supplier from Sany Group “ 杰出贡献供应商 ” ；In overseas markets, relying on its advantages in salt spray resistance and extreme temperature resistance, its products are exported to North America, Eastern Europe, and other regions, 2024 year-on-year increase in overseas revenue 62.71% 。The company plans to invest 1.2 100 million yuan in R&D funds in the next three years to promote the integration of cylinders and Internet of Things technology, achieving remote status monitoring and predictive maintenance, and further consolidating its industry benchmark position.

Conclusion   

Under “ the dual carbon ” goals, mining machinery is accelerating its transformation towards green and high efficiency. Shandong Wantong Hydraulic, with mining excavator cylinders as its fulcrum, through technological innovation and intelligent manufacturing upgrades, continues to create value for global customers, writing a new chapter in the rise of China's hydraulic power.
