Casting and Forging

Casting and Forging

Casting and forging are two different metalworking processes used to shape metals into desired forms. They are distinct methods, each with its own set of characteristics and applications


Process: Casting involves pouring molten metal into a mold, allowing it to cool and solidify, and then removing the casting from the mold.

Types of Casting

Sand Casting

Uses sand molds to shape the metal

Investment Casting

Uses a wax pattern that is coated with a ceramic shell and then melted to leave a cavity for the metal.

Die Casting

Molten metal is forced into a mold cavity under high pressure

Process: Forging involves shaping metal by applying localized compressive forces using a hammer or die.

Types of Forging

Open Die Forging

Metal is shaped between multiple dies that do not enclose the metal entirely

Closed Die Forging

Metal is placed in a die and then shaped by a hammer or press

Roll Forging

Metal is passed through a pair of rotating rolls to achieve the desired shape

Material Properties

Forged parts generally have better mechanical properties, such as strength and toughness, compared to cast parts


Casting allows for more intricate and complex shapes, while forging is often used for simpler, stronger shapes


Casting is often more cost-effective for complex shapes and large quantities, while forging can be more expensive but produces parts with superior strength
