Data from Oxford Languages

FORGING, is one of the plastic forming method which
making the shape of metal such as steel by
beating or hammering. In Japan, forging began in
300~400 CE to make an agricultural tools and accessories.
In Heian-era, forging method has evolutionally
advanced as a Japanese sward manufacturing,
which became the basis of today’s Japanese
forging technology.

What is the difference from other methods?

Process
Methods

FORGING

Method by heating and beating the metal.

MACHINING

Method by cutting (machining) the metal.

CASTING

Method by pouring a melted metal into a mold.

FIBER
FLOW

Continuous fiber flow made along the shape.

Straight fiber flow
trimmed by machining cut.

No fiber flow.

ADVANTAGES OF FORGED PRODUCT

strong

STRONGER, and STABLE
MECHANICAL PROPERTY

Forged product contains a continuous fiber flow which make the part stronger than a casted part.
Thus, the forged part can be designed smaller, lighter and saving space which can give various possibilities in customer’s total designing.

SAVING MATERIAL by FORMING
NEAR NET SHAPE

Near net shape forming can reduce and minimize machining material loss.
We have advantages of cost reduction, and moreover, green friendly by reducing CO2 emission of less material production and less machining process.
