Internal high-pressure forming technology is a new forming technology that has only appeared in recent years, and it is currently a research cutting edge in the world. According to their structural characteristics, It can be formed at one time by internal high-pressure forming, or the profile can be made by the general extrusion method, and then the internal high-pressure forming method is used for correction.

Due to the excellent performance of internal high-pressure forming and the large degree of freedom of design, one internal high pressure forming part can replace the workpiece formed by welding of several parts, thus avoiding the distortion and deformation caused by welding, and it has greater dimensional accuracy and mechanical properties. Its main advantages are: reducing quality and saving materials.

The connecting parts of the aluminum alloy body frame structure are mostly formed by casting, and the casting methods used are mainly semi-solid die casting and other advanced high-precision die casting methods. Semi-solid die casting technology currently has two forming processes: the rheology forming process and the thixoforming process. The former is to feed the liquid metal into a specially designed injection molding machine barrel, It is cooled into a semi-solid paste by applying shear with a spiral device. The latter is to feed the solid metal particles or detritus into the screw injection molding machine, and under the conditions of heating and shearing, the metal particles are converted into the paste and then die-casted.

The aluminum profile enclosure is an enclosure processed on an aluminum profile obtained by aluminum stretching. It has high flexibility and can be cut at any depth. Generally, Generally, there is a circuit board card slot inside, just insert the circuit board directly, and the aluminum enclosure does not need to be fixed again, the convenience is unmatched by other types of enclosures. However, the aluminum profile enclosure generally has poor water resistance and is not suitable for use in the field and harsh environments.
