As two core processes in the forging industry, hot forging and cold forging each form unique advantages based on their high-temperature and room-temperature forming characteristics, while also having their own limitations. The core logic for comparing the advantages and disadvantages of the two lies in "material adaptability" and "performance priority". Clarifying their differences is a key prerequisite for selecting processes on demand, which is of great significance for improving forging quality and production efficiency.

In the manufacturing of key components in industries such as automotive, aerospace, and construction machinery, forging processing directly determines the mechanical properties and service life of workpieces. Different materials like carbon steel, alloy steel, and aluminum alloy have significantly distinct physical properties, and a single forging process cannot meet all forming requirements. Hot forging and cold forging processing, with their complementary technical characteristics, form a "dual-process system" that adapts to diverse materials and performance requirements, becoming a core solution for high-quality forging production.

In industrial manufacturing, forging processing is a key technology that transforms metals — it doesn’t melt the metal, but instead uses "high-temperature softening" and "high-pressure shaping" to turn ordinary metal billets into high-strength industrial components. It’s like giving metal a "fitness and shaping routine," making it more durable and resilient.

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.

After forging, forgings tend to have residual internal stress and uneven microstructure. Annealing or normalizing is required to optimize their properties, laying a foundation for subsequent processing or application. Although both processes consist of core steps of heating, heat preservation, and cooling, their parameter controls differ significantly, and their effects on forging properties also have distinct focuses.

In forging processing, cracks and folds are core defects that affect the quality of forgings. They not only reduce the mechanical properties of products but also may lead to fracture risks in subsequent processing. Identifying the causes of these two types of defects and implementing preventive measures is crucial to ensuring forging quality.
