There are three main types of forging processes defined by temperature: cold forging at room temperature, warm forging between 800-1800 degrees Celsius, and hot forging up to 2300 degrees Celsius. Hot forging allows for more complex shapes with lower pressure but results in scale formation and less accuracy, while cold forging requires high pressure but yields precision, strength and material conservation. Warm forging offers benefits like low pressure deformation, no need for annealing, and excellent formability at lower costs than hot forging.

2. Introduction About Forgings
 The forging is one type of the manufacturing
process. In this manufacturing process involving
the shaping of metal using localized
compressive forces. According to the
temperature there are two types of forgings
process. One is Hot Forgings and second is cold
Forgings.

3. What Is The Forging ?
 Forging is an established metal shaping process
carried out by metal deformation.
 In this process metal is heated on very high
temperature to achieve consistency.
 Once metal is melted down properly, it is filled
into dies to gain needed shape.

4. Forging Temperatures
 Usually forging components are manufactured at
following three temperatures
✔ Cold forging
✔ Warm forging
✔ Hot forgings

5. Cold Forgings Advantages &
Disadvantages
Advantages
 Precision process & Improved parts strength
 Best surface finish
 Material conservation
Disadvantages
 High forming pressures
 Numerous pre-forming steps required
 Low Formability

6. Hot Forgings Advantages &
Disadvantages
Advantages
 Low Forming pressure
 Can forge complex shapes
 Best formability
Disadvantages
 Formation of seale
 Decreased accurancy

7. Warm Forgings Advantages &
Disadvantages
Advantages
 Excellent formability
 Lower Forming pressure
 High deformation ratio
 No annealing needed
Disadvantages
 High tooling costs
 Tooling must withstand forming pressure

8. Forgings Process
 Cold forging, metals are shaped at room
temperature only. In this Process utilized to from
products using several dies.
 It is suitable for little parts or components usually
under 50 IB only.
 Warm forging process is carried out at
temperature between 800 to 1800 degrees
 Hot forging process is carried out at relatively
high temperature usually up to 2300 degrees.

11. Forgings Comparison
 Cold forging is relatively inexpensive as
compared hot forging techniques manufacturing
process. Hot Forging Manufacturers in India
prefer hot forging because of its end results.
 However, it is not possible to carry out hot
forging techniques when you are running with
small budget.
 During cold forging less heat energy is required
and few metal is wasted as compared to hot
forging technique.
