Hot Forging

The hot forging manufacturing process enables the manufacture of highly customised parts with complex geometries due to the large amounts of plastic deformation and the consequent increased ductility and decreased strength of the workpiece. The high temperature guarantees excellent component integrity by distributing the material throughout the forged part and eliminating inclusions. All metallic materials (ferrous and non-ferrous) can be forged in hot condition and thus, hot forging process is the most common and well-known forging process.

The hot forging manufacturing process is performed at a higher temperature than the recrystallization point of the work metal, thus avoiding strain hardening. This induces that a full heat treatment is required on the parts after the forging, to optimize the metallurgical structure and obtain the required mechanical properties.

To limit large dimensional tolerances, and the generation of scale and surface contamination (such as decarburisation in steels, or H2 and O2 contamination in titanium alloys) a strict control of atmosphere furnaces is required. Solid metallurgical knowledge to adjust the forging and the heat treatment parameters and skills to design dies and preform tools for optimized grain flow are of critical importance. Therefore the Research and Development Engineering have tried to find different ways of forging (as cold and warm forging), aiming at decreasing the heating temperature.

However, hot forging remains the only available and high-quality manufacturing process for complex shapes, heavy-weight components and high-duty alloys. The forging division of Farina Group - Setforge masters the whole spectrum of forging techniques and provides a complete development of components, whether they are hot, warm, or cold forged. Setforge combines experienced manpower and state-of-the-art machinery to meet the forging needs of our diverse client base. Our strong, precise, reliable and cost efficient components are successfully applied in a wide range of industries among others aerospace, agriculture, energy, oil and gas. All Setforge process and main product lines are optimised with latest manufacturing solutions and treatments for improved material characteristics and better dimensional accuracy.
