ABOUT THE Forged Engine

A Forged Engine refers to an engine where some of the metallic parts have been made via the forging process as opposed to casting for improved strength and stress endurance.

Before discussing anything relating to forged vs cast metals or forged engines parts both processes will be explained briefly;

 Forged metals or forging is the process of heating metal and pressing it into shape under high pressure usually with a hydraulic press.
Cast metals or casting is the process of pouring molten metal into a mould which is in the shape of the desired metal component.
Forging is required when the engine produces large amounts of torque, horsepower, is high revving or any combination of the three.
It’s difficult to say exactly what amount of power and/or revs an engine would have to be rated at to need forged parts but these three factors can put extra stress on certain components.
The common parts of an engine to be forged will be the pistons and the crankshaft as these parts are subjected to the most stress from the explosions in the cylinder but the camshafts and other moving parts like the valves can also be forged.
Castings have their advantages too which make them the popular choice when the strength of forged metals isn’t required.

PRODUCTS OVERVIEW

• Casting is generally cheaper process with fewer productions runs required.
• It is much easier to make complexed shapes using the casting process.
• The forging process has a size limit, which casting does not.
• While the primary metal is still molten, a variety of other metals and alloys can be added.

Forging can be done with a variety of metals and the usual metals found in engine construction such as steel and aluminium are forged when needed.
Forged engine parts can be found in supercars and other vehicles with engines of similar output and ratings, but there are many aftermarket forged parts.
Other parts of a vehicle can also me made with forged metals such as body panels, parts of the chassis, suspension or even alloy wheels.
