FORGING
Forging process is nothing but the process of giving raw shape to different metals as per the drawings of the final products. There are several processes for forging a component. The most commonly used metal for auto components is steel. ... This process is generally used for longer products like axle shafts etc.

CASTING

Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process.

Automobile Casting Equipment

The automobile industry offers a huge market for the cast products using ferrous, non-ferrous metals and its alloys. Various casting methods are used to produce automobile accessories that are light in weight, easy to maneuver, and cheap.

Zinc Die Casting and Aluminum Die Casting are two most popularly used processes to produce automobile casting equipment.

Zinc Die Casting :
By using a method of Zinc Die Casting a host of automobile equipment can be manufactured as seen from the following figure:

Aluminum Die Casting :
Automobile equipment are generally made of aluminum die castings. They offer the following benefits:

Light weight, just one third of the weight of steel parts.
Auto parts with aluminum can be cast net shape.
Good production run with die cast auto parts produced in hundreds to thousands per day.
Good thermal properties.
Cheaper in cost.

Application of Aluminum Die Cast in Auto Parts
Numerous parts can be cast effectively using aluminum die cast like Valve covers, Wheels, Transmission housings, Engine block, Wheel spacer, Carburetors, Impellers and Fan clutch, Alternator housing etc.


WELDING

The most commonly used welding methods for automotive applications include resistance spot welding (RSW), resistance seam welding (RSEW), metal inert gas (MIG) welding, tungsten inert gas (TIG) welding, laser beam welding (LBW), friction welding (FW) and plasma arc welding (PAW).

Mechanical properties

Brittleness: Ability of a material to break or shatter without significant deformation when under stress; opposite of plasticity,examples:glass,concrete,cast iron,ceramics etc.
Bulk modulus: Ratio of pressure to volumetric compression (GPa) or ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume. brass has highest bulk modulus of 116 GPa.
Coefficient of restitution:the ratio of the final to initial relative velocity between two objects after they collide. Range : 0-1, 1 for perfectly elastic collision.
Compressive strength: Maximum stress a material can withstand before compressive failure (MPa)
Creep: The slow and gradual deformation of an object with respect to time
Ductility: Ability of a material to deform under tensile load (% elongation)
Durability: Ability to withstand wear, pressure, or damage; hard-wearing.
Elasticity: Ability of a body to resist a distorting influence or stress and to return to its original size and shape when the stress is removed
Fatigue limit: Maximum stress a material can withstand under repeated loading (MPa)
Flexibility: Ability of an object to bend or deform in response to an applied force; pliability; complementary to stiffness
Flexural modulus
Flexural strength : The stresses in a material just before it yields.
Fracture toughness: Ability of a material containing a crack to resist fracture (J/m^2)
Hardness: Ability to withstand surface indentation and scratching (e.g. Brinnell hardness number)
Malleability: Ability of the material to be flattened into thin sheets under applications of heavy compressive forces without cracking by hot or cold working means.
Mass diffusivity: Ability of one substance to diffuse through another
Plasticity: Ability of a material to undergo irreversible or permanent deformations without breaking or rupturing; opposite of brittleness
Poisson's ratio: Ratio of lateral strain to axial strain (no units)
Resilience: Ability of a material to absorb energy when it is deformed elastically (MPa); combination of strength and elasticity
Shear modulus: Ratio of shear stress to shear strain (MPa)
Shear strength: Maximum shear stress a material can withstand
Slip: A tendency of a material's particles to undergo plastic deformation due to a dislocation motion within the material. Common in Crystals.
Specific modulus: Modulus per unit volume (MPa/m^3)
Specific strength: Strength per unit density (Nm/kg)
Specific weight: Weight per unit volume (N/m^3)
Stiffness: Ability of an object to resist deformation in response to an applied force; rigidity; complementary to flexibility
