Forging is a metal shaping process using compressive forces, classified by temperature as cold, warm, or hot forging. Common types include impression die forging, cold forging, open die forging, and seamless rolled ring forging, each suited for different shapes and sizes of metal components. Forging is one of the oldest metalworking processes, evolving from traditional smithing to modern industrial methods using various power sources.

1. Different Types of
Forging Process

2. WHAT IS FORGING?
Forging is a manufacturing process involving
the shaping of metal using
localized compressive forces. The blows are
delivered with a hammer or a die.
Forging is often classified according to the
temperature at which it is performed. Cold
forging, warm forging, or hot forging.

Open Die Forging
Seamless Rolled Ring Forging

4. Impression
Die Forging
Commonly referred to as closed-die
forging, impression die forging pounds or
presses metal between two dies that
contain a precut profile of the desired part.
Impression die forging uses steel, aluminum,
titanium and other alloys to produce a
variety of 3-D shapes that range in weight
from mere ounces up to more than 25 tons.

5. Cold Forging
While most forging is done hot, cold forging is
done at colder temperatures.
Cold forging encompasses many processes —
bending, cold drawing, cold heading, coining,
extrusions and more, to yield a diverse range
of part shapes.
These include various shaft-like
components, cup-shaped geometry’s, hollow
parts, all kinds of upset and bent
configurations, as well as combinations.

6. Open Die
Forging
Open-die forging can produce forgings from a
few pounds up to more than 150 tons.
This process is referred to as open die because
the metal is not confined laterally by impression
dies during forging.
Open die forging is ideal for parts over
200,000 lbs. and 80 feet in length.

7. Seamless
Rolled Ring
Forging
Seamless rolled ring forging is typically
performed by punching a hole in a thick, round
piece of metal and then rolling and squeezing
the donut into a thin ring.
Ring diameters can be anywhere from a few
inches to 30 feet.

8. Forging is one of the oldest
known metalworking processes.
Traditionally, forging was performed by
a smith using hammer and anvil.
In modern times, industrial forging is done
either with presses or with hammers powered
by compressed air, electricity, hydraulics or
steam.
