ã€China Aluminum Industry Network】 Technological functions refer to the functions of materials that accept various processing and disposal capabilities.
Casting function refers to some technological functions such as whether the metal or alloy is suitable for casting. It mainly includes the flow function, overflow mold capacity; shortening ability, the ability of the casting to shorten the volume of the casting; segregation refers to the chemical composition inhomogeneity.
Welding function means that the metal material is welded to two or more metal materials through heating or heating and pressure welding methods, and the interface can be satisfactorily applied to the intended characteristics.
The function of the top gas segment refers to the ability of the metal material to bear the function of upset forging without cracking.
The cold bending function means that the metal data can accept twists and turns without cracking at normal temperature. The degree of tortuosity is usually expressed by the ratio of the meander angle α (external angle) or the bending center diameter d to the data thickness a. The larger the value of a or the smaller the d/a, the better the cold bending property of the data.
The stamping function metal material accepts the ability of stamping deformation processing without cracking. Stamping at room temperature is called cold stamping. The inspection method was checked by cupping experiment.
Casting function Metal material can accept plastic deformation without cracking ability in forging processing.

Why use led therapy light?
Red light therapy is a skin care treatment being offered as an alternative to physician-administered laser therapy.
Nost studies is involving red light therapy revolve around the treatment of acne, and of its ability ti get rid of wrinkle, while research is not yet conclusive on the benefits of red light therapy, studies suggest that concentrated red light is absorbed y the mitochondria in the cells and stimulates the generation of more collagen.
