get to know the overall processes of diecastings

Die casting is the preferred manufacturing process for casting metal products.
There are two main process types and many changes in process design.
When the thawed metal is forced into the mold cavity at high temperature
The pressure is then understood as die casting.
This process is best suited for rapid manufacturing of bulk metal parts that require low post-processing
Production and Processing.
The design of most die casting processes has the same goal --
Use the injected smelting metal casting mold.
Relying on dissolved metal, component geometry and component scaling, various die-casting programs can deliver superior results on alternative methods.
Two main types are hot
Room and coldchamber.
These two die-casting changes include-low-
Pressure, vacuum, extrusion and half
Solid diecastings. Hot-
Chamber close-
In some cases, the chamber is considered \"die-casting with goose neck\" and is the most popular in both casting processes.
During this process, the tank chamber of the injection mechanism is completely immersed in a molten metal bath.
A goose neck metal feed program drags the melted metal into the mold cavity.
Although direct immersion into the smelting tank can quickly and easily inject the mold, it can also lead to increased sensitivity of deterioration.
Because of this reality,
The chamber process is best suited for applications using low melting point and high fluidity alloys.
Good hot alloy-
The chamber is equipped with copper, zinc, lead and magnesium. Cold-
Cold Room
The chamber die casting process is extremely similar to the previous process.
The molten metal focuses on reducing the oxidation of the equipment rather than production efficiency, and enters the shooting process immediately or manually.
This will no longer require the injection system to be immersed in a molten metal bath.
For the application of too corrosion of soaking heat
Cold chamber process
The chamber of commerce may be an excellent choice.
These things are characterized by casting metal with high melting temperature, such as metal and aluminum alloy.
Pressure casting of vacuum technology (VPC)
It is a fairly new die casting process with excellent durability and low air hole rate.
This process is similar to low
In addition to the die casting mold and the area of the molten metal bath, the pressure die casting is reverse.
The cylinder chamber can become a vacuum, which requires the molten metal to enter the mold cavity.
This mode reduces turbulence and limits the number of gas inclusions.
Vacuum die casting is particularly beneficial in the intended product
Casting heat treatment. Low-
Low voltage system-
Pressure die casting is a process that is most suitable for aluminum components that are symmetrical around the turning axis.
For example, car tires are often produced through low production
Cabin.
In this type of process, the mold is placed vertically above the position of the molten metal bath and connected via the riser.
When the chamber is pressed in real time, the metal pulls up into the mold.
Eliminating the feeder from this die casting process provides a high casting yield. Semi-
Solid technology-
The solid process, which is an additional procedure, gives the marginal hole rate and the maximum mass.
The equipment simplifies the work item to a smaller sluslu, which is then heated.
When the metal has actually reached the cyclic transition of solids and liquids, resulting in a rather vague consistency, the injection sleeve forces it to enter the cavity and set in the cavity.
The advantage of doing so is to improve rigor. Non-
Black metals such as magnesium alloy and aluminum alloy are most typically used with all semi-metals
Solid diecastings.
Extrusion process of extrusion system is a convenient remedy for casting low fluidity metal and material.
In the process, the molten metal is filled with an open mold and then squeezed to close, forcing the metal into the recessed part of the forming.
The extrusion casting procedure provides very dense products and is also a supplementary procedure for subsequent heatingtreating.
This method is usually associated with smelting materials and is used in applications that require fiber reinforcement.
