In the field of heavy hydraulic equipment manufacturing, the quality of annular forgings directly determines the operational stability and service life of the equipment. A hydraulic heavy factory in Wanzhou, Chongqing, faced issues such as low assembly efficiency and substandard durability when producing large hydraulic cylinder assemblies due to insufficient overall performance of annular forgings. Through specialized technical breakthroughs and process optimization, Jianing Forging provided the customer with targeted ring forging solutions, effectively improving product performance.

Customer pain point analysis

When using the original ring forgings, this hydraulic heavy factory mainly faced three major challenges: First, the dimensional tolerance range of the forgings was too large, causing uneven clearance during hydraulic cylinder assembly, affecting sealing performance; Second, the material's fatigue resistance is unstable, with some components exhibiting early cracks under prolonged high-pressure conditions; Third, suppliers have long delivery cycles and cannot keep pace with customers' rapid prototyping and mass production. These pain points limit customers' product upgrades and capacity release.

Jianing Forge's solution

Jianing Forging optimized the customer's specific needs from three dimensions: materials, processes, and delivery. In terms of materials, select good alloy steel that meets hydraulic heavy-load conditions, and strict pre-furnace composition control helps ensure batch consistency. In terms of process, we use multi-pass forging combined with more precise ring rolling technology, combined with specialized heat treatment curves, to make the grain structure of forgings more uniform and to keep dimensional accuracy within the tolerance range required by customers. In addition, Jianing Forging has optimized production schedules, shortened conventional lead times, and provided phased trial production services to help customers quickly validate and implement mass production.
