Principle Of Aluminum Forging

‌The principle of aluminum forgings‌ is to use the plasticity of aluminum and external force to produce plastic deformation, so as to obtain the required shape, size and certain structure and performance. Specifically, aluminum forgings are to apply pressure to aluminum billets through forging machinery to make them plastically deformed to achieve the required shape and size‌.

The production process of aluminum forgings
The production process of aluminum forgings includes the following main steps:

‌Mold making‌: Make the corresponding mold according to the design requirements.
‌Material preheating‌: Preheat the aluminum to an appropriate temperature, usually not too high or too low, to avoid affecting the material strength or causing cracking.
‌Impact forging‌: Put the preheated aluminum into the mold for forging to make it plastically deformed.
‌Finishing and surface treatment‌: Finish the forged parts to ensure dimensional accuracy and surface quality.
Application fields and advantages and disadvantages of aluminum forgings
Aluminum forgings are widely used in various fields, such as aviation, aerospace, automobiles, railways, electricity, etc., and are particularly suitable for aluminum parts that require high strength, high corrosion resistance, high toughness and other performance requirements.
The advantages include:
‌Compact and uniform structure‌: The internal structure of the forging is dense, and the performance is better than that of die castings, cutting parts and welded parts.
‌Warm forging process‌: It combines the advantages of cold forging and hot forging, reduces deformation force and mold cost, and improves production efficiency.
‌Cold forging process‌: It saves materials and produces high-quality parts with high dimensional accuracy and low surface roughness.
However, aluminum forgings also have some disadvantages, such as high requirements for the control of the material preheating temperature, and improper preheating temperature will affect the material strength or cause cracking and other problems.
