What is forging..!!

Are you interested in learning more about forgings? Forging is a manufacturing process, which shapes a workpiece by applying particular force on it. Please check this out to grab more info on forging and it's different processes.

1. What is Forging?

2. Introduction
●Forging is a manufacturing process that results in the shaping of metal by
using calculated force
●Forging is executed with a power hammer or a die during the shaping process
to produce the intended design of the forged metal object
●It has multiple classifications, identified according to the temperature at
which the forging process is being performed
●This includes cold forging or hot forging, each offering its own distinct
advantages

3. Different types of Forging
❖Hot Forging
➢Hot forging requires the metal to be heated above its recrystallization
temperature
➢This can mean heating metals up to 2,300 degrees Fahrenheit
➢The main benefit of hot forging is the decrease in energy required to form
the metal properly
➢This is because excessive heat decreases yield strength and improves
ductility

4. Different types of Forging
❖Cold Forging
➢Cold forging typically refers to forging a metal at room temperature
➢Many metals, such as steel high in carbon, are simply too strong for cold
forging
➢Cold forging encompasses numerous forging techniques, including
bending, extruding, cold drawing and cold heading
➢However, this increased versatility comes at a cost, because cold forging
requires more powerful equipment

5. Forging Process Categories
●Beyond basic hot and cold forging, many specific processes exist
●This broad range of processes can be grouped into three primary umbrella
groups
○Draw forming decreases the width of the product and increases length
○Upset forging increases the width of the products and decreases length
○Compression forming provides forging flow in multiple or customized
directions
●These three categories entail many different specific types of forging

6. Closed Die Forging Process
●Closed die forging, sometimes called impression die forging, employs the use
of molds
●These molds are attached to an anvil while a hammer forces molten metal to
flow into the cavities of the die
●Multiple strikes and/or die cavities are often used when forging complex
geometries
●High initial tooling costs make closed die forging expensive for short-run
operations
●This forging process becomes cost-effective as parts produced increases

7. Open Die Forging Process
●Open-die forging is also known smith forging
●When flat dies that have no precut profiles engage in forging, the process is
called open die forging
● The open design allows the metal to flow everywhere except where it touches
the die
●Therefore the operator needs to orient and position the workpiece to get the
desired shape
●Open die forging is an important technique for many types of
manufacturing.

8. Press Forging
●In press forging, the main forming factor is compression
●he metal sits on a stationary die while a compression die applies continuous
pressure, achieving the desired shape
●The metal's contact time with the dies is considerably longer than other types
of forging
●This forging process benefits from being able to simultaneously deform the
entire product, as opposed to a localized section
●Another benefit of press forging is the ability of the manufacturer to monitor
and control the specific compression rate
