Blanks: Forging

Forging involves a material which is pre-heated and then shaped by a force created by a or a hammer. In the past, forging was used by a with the use of a tool called a . Nowadays we use forging to create a high number of identical parts in a short time with the use of machine-powered . Hot forging is carried out at a temperature to prevent of the material. We may use cold forging when we want to reshape soft metal or materials. Using cold forging on hard materials might cause .

Blanks: Rolling

Rolling is a very important manufacturing process. Most metal products undergo this procedure at some point in manufacturing since rolling is often used while creating new raw metals. Rolling allows metal to be turned into or blooms. have a rectangular shape while blooms have a square . With the use of a mill, these work-pieces can be rolled down into different shapes such as sheets, rods, plates, coils, , etc. It is also possible to use this process on plastic, , and paper materials in a similar way. Whether to use or hot rolling is chosen according to the type of material we decided to reshape.

The used material is plastically deformed by forces which occur between two spinning which spin in opposite directions to each other. The material is passed through these spinning . This causes a reduction of the of the material while changing its form. The which was reduced from its original value is called a . While the shape of the work-piece is changing, its remains the same.

Blanks: Drawing and Bending

Drawing is based on a procedure of the metal material through a die or a . This process employs a die which is called a punch. The work-piece is mechanically gripped and pulled through the die. The work-piece gains a cylindrical or box-like shape while it is being pulled through the die. According to the shape of the die, the work-piece gains differently shaped sides. They can be straight, curved, , or some mix of these three. We may draw the work-piece through more dies which will help to reduce its while increasing its . The of its walls is only marginally changed.

Drawing is normally conducted at temperature. It is an easily automated and accurate metal process with minimal upkeep and very short downtime. It allows us to produce work-pieces of simple to complex shapes in short periods of time.

Bending is used to change the form of sheet metal along the straight in the material without changing its . There is a little to no change in the of the material. Bending helps to strengthen the work-piece while increasing its . It may also be used for purposes or to eliminate sharp edges. It is usually conducted at room temperature, but it may be performed while the material is heated as well.

For bending, we generally use a die which is shaped according to the desired change of the sheet metal. Dies for bending are usually made from iron or steel. To create the desired bend, we may need to use several different metal bending processes. Generally, we are bending metal but bending of tubes or rods is also possible. The most common products of metal bending are and U-shaped work-pieces.
