Liquation and Extrusion Die Casting
Technique Difference
Liquation and extrusion die casting are two die casting techniques used in the production process. The former is a process that uses high pressure to force liquid metal into a die, while the latter is a process that forces metal under pressure through an extrusion die that is shaped to produce the desired component. Both processes use electric current to heat the metal, and then form it into the desired shape. This paper will discuss the differences between liquation and extrusion die casting.
One difference between the two processes is the speed of production. Liquation die casting is usually slightly faster than extrusion die casting. Since liquation die casting is performed at a higher pressure, the metal is quickly forced into the die, which decreases the cycle time. Extrusion die casting is slightly slower, since the metal has to be forced through a die opening, which adds to the overall cycle time.
A second difference is the complexity of the parts that can be produced. Liquation die casting is more suitable for producing more complex parts, since the process allows for greater detail in the design. Extrusion die casting is better suited for simpler components, since the extrusion process limits the amount of detail that can be created.
In addition, the material cost associated with each process is another difference. Liquation die casting is typically more cost-effective than extrusion die casting, since it requires less material. Extrusion die casting, on the other hand, requires more material, since the metal needs to be forced through a die.
Finally, the finish of the parts is also a difference between the two processes. Liquation die casting produces a smoother finish, since the die applies pressure evenly over the entire surface of the part. Extrusion die casting, on the other hand, usually produces parts with a rougher surface finish, since the metal is forced through a die that has ridges and cavities.
Overall, liquation and extrusion die casting are two processes used for die casting. One key difference between the two processes is the speed of production, with liquation being slightly faster. Additionally, liquation die casting is more suitable for creating more complex parts, while extrusion die casting is more suited for simpler components. Furthermore, the material costs associated with each process are different, with liquation being more cost-effective than extrusion. Finally, the finish of the parts produced is also different, with liquation producing a smoother finish and extrusion a rougher finish.
