Die Forgingby: Rox A. Liberato

Die Forging is a manufacturing process involving the shaping of metal using localized compressive forces. Forging is often classified according to the temperature at which it is performed: "cold", "warm", or "hot" forging. Forged parts can range in weight from less than a kilogram to 580 metric tons. Forged parts usually require further processing to achieve a finished part.

Die Forging

Forging can produce a piece that is stronger than an equivalent cast or machined part. As the metal is shaped during the forging process, its internal grain deforms to follow the general shape of the part. As a result, the grain is continuous throughout the part, giving rise to a piece with improved strength characteristics.

Types of Die forging

involves the shaping of heated metal parts between a top die attached to a ram and a bottom die attached to a hammer anvil or press bed. Metal parts are worked above their re crystallization temperatures-ranging from 1900°F to 2400°F for steel-and gradually shaped into the desired configuration through the skillful hammering or pressing of the work piece.

Open Die Forging

is the forming of complex-shaped parts from a metal semi-product between two engraved tools (dies) by hammering or pressing with a closed-die forging press.

Process of Die Forging

The first stage is for us to develop materials to meet your technical specifications. Thanks to the world renowned expertise of our metallurgists, production processes are then developed, modeled and optimized in order to ensure their reliability and reproducibility.

Design

Heat treatment involves changing the structure of a part through predetermined heating and cooling cycles in order to improve mechanical properties such as hardness, yield strength, etc.

Heat Treatment

In order to obtain the material properties required for your particular application, the industrial phase involves a rigorous (air or vacuum) melting process followed by re melting of special steels, alloys or super alloy s. Our extensive catalogue comprises some 350 grades.

Melting

Machining is a family of manufacturing processes that involve forming the shape of metallurgical products (bars, parts, etc.) by removing material using cutting equipment.

Quality controls are performed throughout the manufacturing process in order to meet the most demanding customer requirements.
