What are the production processes of Aluminum forgings?
Aluminum forging offers a range of expertise types that can be adjusted to produce custom products based on your unique requirements. The overall classification of aluminum forging expertise can be divided into five main categories:
Cold Forging: Aluminum cold forging shapes the material at room temperature and gives it improved strength and precision.
Hot Forging: This methodology of hot forging aluminum is highly specialized since it demands increased temperatures to fasten the fluidity process to create complex structural designs.
Drop Forging:Drop aluminum forging utilizes the force of gravity or mechanisms to create exact parts of increased strength and complexity.
Rolled Ring Forging:Aluminum-molding rolled rings create the rings from one piece of stock by rolling and forming it. This option allows for transmitting more precise directions and p-stage processing.
Open Die Forging:Aluminum open dies form any geometric shape of aluminum material in the forge. The process uses two flat dies, and heel-to-toe dies are the most common.
Closed Die Forging:Aluminum closed dies shape the material and their connection in a more precise fashion using preset producers. It allows for the creation of any form on aluminum materials.
Understanding the Differences Between Forging and Casting
In forging, deformation of the material in solid form, often by hammering or pressing the material, creates the desired shape.In casting, metal is melted and poured or forced into a mold made in the shape of the desired item.
Production flexibility:The open die forging process accommodates a wide range of production batches and enables short delivery times.
Strength:Whether it is open die forging or closed die forging, the forging process is superior to casting in predictable strength characteristics, ensuring high strength of the parts.
Prevention of defects:The grain flow direction produced by forging pre-processing is consistent with the direction of maximum strength, which improves defects such as dendritic structure and alloy segregation.
Production reliability:The forging process is easier to control, ensuring product consistency and reliability.
