Techniques
In the field of metal processing, forging and casting are two
common and important process methods. Although they both involve
the process of heating, shaping and cooling metal, there are many
fundamental differences between them.
What is metal forging?
Forging is a process of shaping and deforming metal by applying
external force. During the forging process, the metal is processed
into the desired shape at high temperature, and its structure and
properties are also improved. The forging process is widely used to
manufacture various high-strength and high-toughness parts, such as
aircraft engine blades, gears, shaft parts, etc.
What is metal casting?
Casting is a process of pouring molten metal into a mold and
forming the desired shape after it cools and solidifies. During the
casting process, the metal is transformed from liquid to solid, and
its structure and properties also change accordingly. The casting
process is widely used to manufacture various parts, such as
mechanical parts, cast iron pipe fittings, steel castings, etc.
The connection and difference between metal casting and forging
processes:
Material flow properties: Casting is the flow of liquid metal to
form a shape, while forging is the solid metal to achieve a shape
through plastic deformation.
Processing method: Casting is formed by a mold, and forging is
deformed by hammering or applying force with a press.
Surface quality: The surface roughness of castings is high and
requires subsequent processing; while the surface quality of forged
parts is good, which can reduce the workload of subsequent
processing.
Production efficiency: Casting is suitable for mass production and
has high efficiency; forging is suitable for small batch production
and has relatively low efficiency
In practical applications, the selection of casting and forging
needs to be determined according to specific circumstances.
For some parts with simpler shapes and low requirements for
strength and toughness, casting is an economical choice. Because
the casting process can produce parts with more complex shapes, and
the required properties can be obtained by controlling the alloy
composition.
However, for some parts with higher requirements for strength and
toughness, such as aircraft engine blades, gears, etc., forging is
a better choice. Because the forging process can improve the
organization and properties of the metal through shaping and
deformation, and improve the bearing capacity of the parts.
