To put it simply, metal processing technology is through a series of means, the metal material "pinch", "cut", "spell" into the shape and performance of the process. It is like the process of dough becoming steamed bread, but the metal is much harder than the dough, and the tools and methods used are much more complex.

Common processes of metalworking include casting, forging, cutting, welding, and surface treatment. Here are some examples of this example:

1.Casting: "mold" the metal

Casting is one of the oldest methods of metalworking. It works by melting the metal into a liquid, then pouring it into a mold, and then it becomes the desired shape.give an example:

The home faucets and some car engine shells are made through the casting process. Because the mold can be made very complex, the casting is particularly suitable for parts with complex shapes.

2.Forging: forcefully "beat" the shape

The forging process is characterized by using a large hammer or machine, exerting great force on the metal, "knocking" it into the shape we want. Through this "beating", the tissue inside the metal becomes tighter and stronger.give an example:

The head of a hammer, the crankshaft of a car, and even the parts used on an aircraft landing gear are usually forged because they require great force and cannot be easily broken.

3. Cutting and processing: "cutting out" the precision parts with a knife

4.Cutting is like a carpenter digging wood with a plane, but the mechanical tools such as lathes and milling machines are used here to "cut" the metal into the size and shape we want.give an example:

5.The metal frame in the phone and the gear inside the machine are all produced in this way. This process is particularly suited for parts that require high precision.

6.Surface treatment: Make the metal more "durable"

The surface of metal products sometimes needs special treatment, such as a layer of rust coating, electroplating a layer of metal film, etc. This makes the metal more durable or better.

give an example:

The metallic paint on the surface of the car and the shiny shell of home appliances have been treated to make them more wear-resistant and more beautiful.

sum up

Metal processing technology is not only to make the metal "deformation", but also a combination of science, technology and art knowledge. From casting and forging to modern 3D printing, each process has its own charm, which is also pushing our life forward.
