Methods of making metal parts

 

In general, several different methods are used to make metal parts. Each method depends on the type of piece; That is, the required strength for the metal part, the complexity of the design and model of the part, the setting of the part, the type of alloy with which the metal part is to be made and several other factors are determined. Many of these methods are several thousand years old, and some have evolved or improved with the advancement of technology.


Humans have generally acted in three ways to make metal parts.

  3. The metal is completely melted and poured into a mold to form

With this background, we will continue to examine each of the above methods and get acquainted with the common and commercial names of each.

 

Types of metal forming

 

For forming metals; The metal with which the piece is to be made; First, it is heated in an oven to form a kind of dough and of course not to melt.

They then shape it in three ways.

  1. Navard
  2. Extrusion
  3. Shaping with forged mold

Navard
In this method, the metal is heated to a temperature to form a paste. Then, by rubbing, pressing and hitting it, they form it and make the final piece. Parts made in this way; Types of sheets, corners, round bars, certain types of pipes and cans and similar parts.

 

Extrusion
This method is for parts that are more complex, and of course this complexity is only at the longitudinal cross-section of the part. That is, the piece is repeated longitudinally at a specific cross section. In this case, they make a mold from the cross section of the piece; The metal is then heated in a kiln to paste, after which the molded metal is pressed through a mold. By doing this, the piece takes the shape of the cross section and cools down.

 

Forging
UsuallyScience Articles, parts that have a high degree of sensitivity and must have a good compression and also have a sensitive safety and must be free from defects of casting methods and also do not have a very large set-up and volume are produced with this method.
