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.
In the field of heavy-duty transmission machinery, the quality of cylinder forgings, as key structural components, directly affects the stability of equipment operation and service life. During the process of upgrading its production line, a certain transmission machinery factory set higher requirements for the overall performance of the cylinder forgings.
A transmission machinery factory located in Luzhou, Sichuan, specializes in the manufacturing and assembly of large-scale transmission equipment. To meet the stringent requirements for load-bearing capacity and fatigue resistance of the new generation products, the plant needed to purchase a batch of reliable performance shell forgings. After extensive evaluation and on-site inspection, they ultimately chose to cooperate deeply with the professional forging supplier—Jianing Forging.
During preliminary research, the customer found the following prominent issues in some of the forgings with cylinders on the market:
- The forged microstructure is not dense enough, resulting in significant strength fluctuations in batch parts, which cannot meet the stability requirements of the transmission system under high-load conditions;
- Insufficient machining allowance control accuracy, long subsequent machining cycles, and significant material waste, directly affecting delivery efficiency and costs;
- Low internal flaw detection pass rate, frequent inclusions, cracks, and other defects, posing significant safety risks.
These issues have become the "bottleneck" restricting the factory's product upgrades.
To address these pain points, Jianing Forging, relying on a mature forging process system, has tailored a tube forging solution for transmission machinery factories:
- Uses multi-directional forging + temperature-controlled forging technology, making the internal structure of the forging more uniform and dense, narrowing the range of mechanical performance fluctuations, and providing proven strength that better meets customer technical agreement requirements;
- Introduced high-precision CNC ring forging equipment to keep machining allowances within a reasonable range, reducing the weight of a single blank by about 8% compared to traditional processes, thereby lowering post-processing costs;
- Supporting implementation of ultrasonic + magnetic particle flaw detection, improving internal defect detection rates and maintaining batch pass rates above 98%. Through full-process quality traceability, we provide reliable bulk supply support for transmission machinery factories.
