During the forging processing, cracks and oxidation are the most common quality defects. They not only affect the mechanical properties and service life of forgings, but may also lead to product rejection and increase production costs. Clarifying the causes of these two types of defects and adopting targeted solutions are the key to improving forging quality and reducing loss. 

Forging is a key process that uses external force to induce plastic deformation of metal blanks to obtain parts with desired shape, size and performance. As the three core forging processes, hot forging, cold forging and warm forging have significant differences in process characteristics, applicable materials and application scenarios due to different processing temperatures. Reasonable selection of process type is crucial for improving part quality and reducing production costs. The following analyzes the differences and suitable scenarios of the three from core dimensions.

Forging quality directly determines the reliability and service life of end equipment. Especially in high-end fields such as aerospace and automotive, the requirements for forging quality are extremely strict. Accurately identifying the superiority of forgings requires considering both appearance integrity and internal performance, to avoid potential safety hazards caused by surface defects or substandard mechanical properties. This article sorts out 4 core identification methods, progressing from appearance to performance, to help quickly and accurately judge the quality of forging processing.

In the field of industrial manufacturing, forging processing has always been an indispensable core technology when it comes to obtaining metal parts that combine toughness and strength. Unlike casting, which relies on the pouring of liquid metal, forging achieves the shaping of metal in a solid state through the "dual action" of high-temperature heating and high-pressure forging, ultimately "forging" industrial "frameworks" that can withstand harsh working conditions.
