Metal Forming: Drop Forging, Wrought Iron Forging, Bending, Rolling, and Diecasting

Metal forming is a critical process in manufacturing that involves altering the form, surface, and material properties of a workpiece while preserving mass and cohesion. The processes of forming use various techniques such as drop forging, wrought iron forging, bending, rolling, and diecasting to shape metals into desired forms.

Drop Forging

Drop forging is a metal forming process that involves shaping metals using localized, compressive forces after heating the metal to a point where it's malleable. This process yields strong, durable parts that are resistant to wear and tear. Drop forging is commonly used in industries such as automotive, aerospace, and heavy machinery.

Wrought Iron Forging

Wrought iron forging is a metalworking process that involves shaping wrought iron, a type of iron that has been hot worked after smelting. This process can be done using various techniques, including hammering, rolling, and forging, to create a wide range of products, including tools, machinery parts, and architectural elements.

Bending

Metal bending is a metal forming process that involves bending a metal workpiece to a predetermined angle by pinching it between a punch and a die. This process is commonly used to bend metal sheets into V or U shapes for architectural, automotive, and other purposes.

Rolling

Rolling involves continually feeding a long strip of metal through drum rollers to attain the desired cross-section. This process is highly efficient and cost-effective, making it the preferred choice for producing long lengths of sheet metal with consistent profiles. Roll forming can handle various metals such as steel, aluminum, copper, and more.

Diecasting

Diecasting is a metal forming process that involves pouring liquid metal into a mold containing a hollow cavity of the desired shape. As the liquid cools and solidifies, it takes on the shape of the mold. This process is ideal for producing complex shapes and designs with intricate details that would be difficult or expensive to produce using other methods.

These metal forming processes are widely used in different industries, including automotive, aerospace, heavy machinery, and more. The evolution of these processes has been immense, with the use of software simulation playing a significant role in predicting problems and shortening the time needed to optimize solutions. The natural evolution of materials has led to the need for continuous research to achieve new features, including the identification and characterization of defects, exploration of new parameters for known processes, and the development of relatively recent processes such as single point incremental forming.
