What is piercing in metal?
Piercing is a shearing process in which raw metal is pierced with a machining tool, resulting in the creation of a circular or other shaped hole. As the raw metal is pierced, the metal from the newly created hole is considered scrap.
What is die in sheet metal?
A die is a tool used in many manufacturing industries and extensively in sheet metal fabrication . Dies are used to cut or shape material by using a press and are generally customized for the specific item to be created.
What is piercing in forging?
Piercing is a metal forging technique that is often performed as an auxiliary process in conjunction with other forging processes, in the manufacture of a part. Piercing does not break through the metal’s surface, like a drilling operation. Instead, the cavity is pressed into the work, hence it is a forging operation.
How is piercing performed?
Piercing involves using a sharp object to make a hole in the skin. A piece of jewelry is then inserted into the hole. Piercing is most commonly done on the ears, but it can also be done on the tongue, lip, and other body parts. Piercing can be done for artistic expression, beauty, or spiritual reasons.
What is the piercing process?
Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate. The process and machinery are usually the same as that used in blanking, except that the piece being punched out is scrap in the piercing process. For simple piercing operations a pancake die is used.

What is hot piercing?
Hot piercing is the first step of seamless steel tube manufacturing,it is hot pierced from round steel billet into hollow tube sections,and ready for futher cold drawing production. It is very important step to keep good OD and ID tolerance, as well as good concentricity.
What’s the difference between punching and Piercing Metal?
The major differences are as follows: In blanking the portion of material which is cut out from the sheet is the required part. Whereas in piercing the portion which is punched out from the sheet is scrap. The blank dimension is determined by the die size.
What do you need to know about metal piercing?
Piercing metal is a process used to provide holes, slots and notches with tight tolerances within sheet metal or metal components. Piercing metal provides a clean cut and high output rates often making it a more productive method than drilling or using a laser.
What’s the difference between blanking and piercing die punch?
In blanking, the blanked piece of material is the product and while in piercing, the material that is blanked is scrap while the remaining part of the strip is the product, as shown in the Figure. In this project, blanking and piercing are used to produce component.
What kind of operation is a sheet metal piercing?
This is a form of piercing operation where the part is cut and separated from the sheet metal. For example in progressive dies, the final stage is often a cut-off station where the stamped product is cut and removed from the strip. This is similar to cutoff operation.
