Case Background

An agricultural machinery factory in Xi'an, Shaanxi, faced multiple technical challenges during the processing of carbon steel forgings. The factory mainly produces key agricultural machinery components, with high requirements for forgings' strength, wear resistance, and dimensional accuracy. The company has long relied on traditional forging processes, making it difficult to meet the dual demands of mass production and stable quality, and urgently needs partners with mature carbon steel forging processing capabilities.

Customer Needs and Challenges

This customer encountered the following issues in actual production: First, insufficient internal microstructure density of forgings, which easily causes cracks to appear during use; Second, there are large dimensional deviations between product batches, requiring frequent repairs during assembly, which affects production efficiency; Third, the surface of forgings under traditional processes is severely oxidized, resulting in large machining allowances and obvious material waste. The customer wanted a carbon steel forging solution that both contributed to mechanical performance, maintained stable control over dimensional tolerances, and delivered excellent surface quality.

Solutions and product advantages

To address these pain points, Jianing Forging offers the following carbon steel forging processing solutions:

• Optimizing forging processes: By combining multi-directional forging with temperature-controlled forging, grain refinement and looseness are effectively refined, looseness eliminated, and the density and overall mechanical properties of forgings are improved.
• Fine molds and CNC machining: Independently designed high-precision forging dies, combined with CNC machining centers for post-processing, key dimensional tolerances are kept within ±0.2mm, meeting customers' maintenance-free assembly needs.
• Surface treatment technology upgrade: Through reasonable heating specifications and anti-oxidation coating technology, the depth of the decarburized layer on the forging surface is controlled below 0.3mm, reducing subsequent processing allowance and lowering material waste.
• Full-process inspection support: From raw material entry to finished product shipment, multiple tests including hardness, metallography, and dimensions are conducted, ensuring stable performance and reliable quality for every batch.

This solution helped the customer increase the forging qualification rate to over 98%, shorten the processing cycle for single parts by 15%, and reduce overall costs by about 10%, earning high recognition from the client.
