Shanxi Jianing Forging can process large-diameter pressure vessel shell forgings made of carbon steel, stainless steel, and alloy steel. The station has a wealth of real-world cases of cylinder forging, fully demonstrating the forging capabilities of large-size cylinders and the corrosion-resistant results of finished products.
A hydraulic equipment factory in Zhaotong, Yunnan, set strict requirements for the performance and dimensions of cylinder forgings during the production of hydraulic cylinders. This batch of forgings is used under high-pressure conditions, with high standards for material density, mechanical strength, and dimensional consistency. After taking on this task, Caring Forging developed a targeted full-process plan from billet preparation to final forming.
Customers initially faced the following issues: First, the wall thickness of the barrel forgings is relatively large, and traditional processes tend to cause internal looseness or uneven structure; Second, strict tolerance requirements for coaxiality and roundness are required, making it difficult for conventional forging methods to stably meet standards; Third, project delivery times are tight, requiring shorter production cycles without sacrificing quality.
By optimizing the heating curve and forging ratio, Jianing Forging effectively eliminates internal structural defects, resulting in finer grains and rational distribution of flow lines in forgings. Using specialized tooling and precise calibration processes, coaxiality is controlled within 0.3mm, and roundness tolerances meet design drawing requirements. At the same time, we reasonably adjusted multi-process parallel operations to complete delivery two days ahead of schedule, achieving a finished product pass rate of 1.
