Metal casting service is one of the oldest manufacturing or fabrication methods used to make metal parts. This metal working process involves pouring molten metal into a mold and widely used in both manufacturing and fine art.
How does it works
Casting is most often used to make complex and large shapes which would have been difficult with other manufacturing methods.
When one comes to know how to execute metal casting services, he finds a molten liquid metal is transferred into a mold by a crucible. This mold contains a negative impression and in case of 3D printing metal casting it contains a three-dimensional image of the intended shape. The liquid metal is forced or poured into the mold cavity either by gravity or by high pressure. Then the metal and mold is cooled. Once the cast part is solidified it is removed from the mold and fettled.
Some Metal casting methods
The modern metal casting can be divided into two main categories by the basic nature of the mold design:
- Expendable mold:
- Investment casting
- Sand casting
- Shell molding
- Full mold or foam
- Reusable mold:
- Permanent molds
- Semi-transparent molds
- Die casting
- Pressure casting
- Centrifugal casting
Almost all metals can be used in metal casting service. Most popular among them are steel, iron, aluminium, magnesium, brass alloy, bronze and more.
Why Choose Metal Casting
Metal casting process has been known for thousands of years and is widely used for its numerous advantages:
- Can produce complex shapes and designs and easily creates multiple of the same object
- An inexpensive way to produce huge and heavy parts
- Cheaper for medium to large quantities comparing to other methods
- Ideal to produce large components in one-piece cast
- Can range in size from a few grams to thousands of pounds
- Incredibly versatile process as almost all metals can be cast
- Steel casting services delivered enough strength and shock resistance
- Near net shape with a very minor post processing
- Create high quality metal parts faster
For these above benefits metal casting is oftenly choosen over other metal working processes.
Application
Metal casting is suitable for mass production and has broad uses in transportation (aerospace, railways, automobile) and jewellery industries.
Casting process is used to make nearly everything from defense weapons to household appliances, from electrical components to artistic sculpture, from medical devices to toys .
So, without any doubt one can easily rely on this age-old manufacturing process to create metal objects for a wide range of application.
