Hot die forging production is a commonly used metal forming process. By heating the metal material to its plastic deformation temperature, and then applying pressure to fully fill the mold cavity, the product of the desired shape is finally obtained. This process is widely used in a variety of industries, including automotive, aerospace, energy and construction machinery. Liju provides die forging, closed die forging, net shape and near net shape hot forging services to OEM customers around the world. In addition, we also provide large volume forged parts from 0.015KG to 40KG.   Liju’s forging project expertise includes products such as steering knuckles, forklift parts, automotive connecting rods, wheel hubs, ball joints, rockers, automotive hinges, control arms, spindles, forged shafts and gear sets. The core steps of hot die forging production include the following aspects:   1. Material preparation: Select suitable metal materials, usually high-strength alloy steel or stainless steel. These materials have good plasticity and heat resistance and can withstand deformation at high temperatures.   2. Heating: Heating the metal material to an appropriate temperature, usually above the recrystallization temperature of the material. This reduces the material's strength and increases its plasticity, making it easier to deform.   3. Forging: Place the heated metal material into the mold and apply a certain amount of pressure to fully fill the mold cavity. This step requires precise control of heating temperature and force application parameters to ensure product accuracy and quality.   4. Cooling and post-processing: After forging is completed, cool the forging to room temperature. Subsequently, annealing or other heat treatment processes may be required to relieve internal stresses and improve the material's mechanical properties.   Hot die forging production offers many advantages. First of all, due to the forming at high temperatures, metal materials have high plasticity, and products with complex shapes and precise dimensions can be obtained. Secondly, compared with traditional cold forging, hot die forging can improve the density and mechanical properties of the product and reduce the occurrence of defects and cracks. In addition, hot die forging can also improve the microstructure and wear resistance of the material, and improve the life and performance of the product.   In summary, hot die forging production is an important metal forming process that is widely used in various industrial fields. Through reasonable material selection, precise heating and force control, high-quality, high-strength forgings can be obtained to meet the product performance and quality needs of different industries.
