What Does Engine Forging Mean?

[DelCorbin]

Engine forging is a very traditional manufacturing process. More details are as follows: Detailed Introduction: The commonly referred-to all-aluminum engine is one where both the cylinder head and cylinder block are made of aluminum alloy, whereas an engine with an aluminum cylinder head and a cast iron cylinder block is generally still referred to as a cast iron engine. Due to cost considerations, the adoption of all-aluminum designs for the cylinder block came much later than for the cylinder head. The cylinder block is the heaviest part of the engine, so using aluminum alloy materials can reduce the engine's weight, thereby achieving the goal of reducing the overall vehicle weight. Since forging is done manually, it incurs significant labor costs. Forging high-temperature metal allows more minerals to penetrate into the metal particles, thereby improving the strength and heat resistance of the parts, which ultimately benefits the engine's speed increase and power output. Additionally, forging can improve the friction coefficient of some components; for example, pistons manufactured using forging processes can better reduce surface friction coefficients.
