Electro-Driven Innovation: Electric Cylinders Lead the Green Upgrade of Hydraulic Equipment

Recently, Shandong Wantong Hydraulic Co., Ltd., a nationally recognized "Little Giant" enterprise specializing in niche expertise and innovation (hereinafter referred to as "Wantong Hydraulic"), launched its new line of electric cylinder products. Featuring "electric drive, precise control, and zero emissions" as their core advantages, these products are perfectly suited for applications such as automated production lines, precision equipment, and new-energy machinery, filling the domestic gap in customized electric cylinders with medium tonnage capabilities.

According to WanTong Hydraulic R&D Center, the electric cylinder features a "servo motor + ball screw" drive mechanism, replacing traditional hydraulic systems to eliminate hydraulic oil leakage entirely—thus meeting eco-friendly and green standards. Equipped with a built-in high-precision encoder, it achieves exceptionally high positioning accuracy, perfectly aligning with the precise control requirements of automated production processes. The cylinder body is crafted from high-strength aluminum alloy, significantly reducing its weight compared to conventional hydraulic cylinders, making it easier to integrate and install into equipment. The product range covers a wide spectrum of rated thrust—from small to medium-sized models—and offers multiple standard stroke lengths. It also supports customizable features such as adjustable speed (ranging from low to high) and force-control modes, making it ideal for applications like precision push-and-pull operations on assembly lines, precise lifting and lowering of delicate instruments, and battery installation in new-energy vehicles.

Enterprise Strength: Electric Control Technology and Production Capacity Support

As one of the first companies listed on the Beijing Stock Exchange, Wantong Hydraulics has assembled a dedicated R&D team specializing in electric cylinders, equipped with end-to-end development capabilities spanning motor selection, lead screw design, and electronic control programming. The company has already secured multiple patents related to electric cylinders. Additionally, Wantong has established a specialized testing platform for electric cylinders, capable of conducting precision positioning tests, noise assessments (with operating noise levels kept remarkably low), and durability tests lasting hundreds of thousands of cycles—ensuring that its products deliver reliable performance across a wide temperature range, from sub-zero to normal ambient conditions. Leveraging its "Intelligent Production Line for Electric Hydraulic Components," the company boasts an annual production capacity of electric cylinders that can easily meet the bulk procurement needs of automated equipment, while maintaining a competitive delivery timeline.

Market Application: Automation Scenarios Garner High Recognition

At a new-energy vehicle factory in Jiangsu, the battery assembly line equipped with Wantong Hydraulic Electric Cylinders has been operational for several months, successfully completing the precise installation of tens of thousands of new-energy vehicle batteries. The positioning accuracy remains exceptionally low, while the system also demonstrates significant energy savings compared to conventional hydraulic-driven assembly lines—and crucially, it eliminates the risk of hydraulic oil contamination. "The automated production line demands high precision and environmental standards," said the factory's Equipment Director. "Wantong's electric cylinders deliver unmatched precision control and boast zero-emission characteristics, making them an ideal match for our manufacturing needs." Additionally, these products have been deployed at a leading precision instrument manufacturer in Shanghai, where they are used to adjust the lifting mechanism of instrument testing platforms, perfectly supporting high-precision inspection tasks.

Wan Tong Hydraulic's Marketing Manager revealed that electric cylinders are currently being supplied in bulk to automation production lines at companies such as Foxconn and CATL, with plans to expand into overseas markets to meet the growing demand for upgrading automation equipment in Europe and North America. Moving forward, the company will develop intelligent electric cylinders equipped with force feedback functionality, further supporting the flexible advancement of automated operations.
