Case Summary

During the long-term production process, a hydraulic equipment factory in Suihua, Heilongjiang, has continuously raised performance requirements for key load-bearing components—the hydraulic cylinder piston rod connectors. The factory's existing purchased dies and forgings have issues such as poor dimensional consistency and loose internal microstructure, which directly affect the equipment's sealing life and operational stability. After multiple rounds of inspections and sample trials, the factory finally established a partnership with Jianing Forging, which provided specialized die forging solutions tailored to its operating conditions.

Customer pain points

This hydraulic equipment factory has long faced the following problems:

• Large dimensional fluctuations between batches of die forgings require frequent adjustments during assembly, affecting production line cycles.
• There are slight pores and segregation inside the forging, and after quenching and tempering, the hardness distribution is uneven, leading to premature wear of the sealing surface.
• Original suppliers cannot provide complete material reports and non-destructive testing records, making quality traceability difficult.
• Delivery cycles were unstable, with production plans repeatedly interrupted due to delays in forging arrival.

Product advantages

To address these pain points, Jianing Forging has customized the following solutions for this project:

• Mold design and simulation optimization: Numerical simulation technology is used to predict forging flow lines, helping to distribute metal flow lines along the force direction and eliminate loose defects.
• Standardized process control: From feeding and heating to forging and trimming, each process set a process parameter range and records it in real time, helping to keep dimensional deviations within 0.3mm within the same batch.
• Full inspection and traceability system: Before leaving the factory, each forging undergoes ultrasonic flaw detection and hardness testing, along with a 3D scan report that users can scan to check production records.
• Flexible production scheduling and stocking: Based on the plant's monthly usage, semi-finished blanks are stocked in advance, the delivery cycle is reduced from the usual 30 days to 15 days, and a 24-hour emergency response is promised.
