Furthermore, although some engineers have proposed designing cast crossbeams to also function as air reservoirs, reliable solutions are still lacking in terms of air reservoir capacity, sealing, corrosion resistance, and cleanliness.

Thread sealant can be applied when sealing the threads.

[0054] Corrosion resistance: The whole electrophoresis is adopted. Because there are large first protrusions 21 and second protrusions 22 on both the top and bottom, it can ensure that there is no liquid accumulation or exposure of the bottom during electrophoresis.

[0055] Cleanliness: The main factor affecting cleanliness is the pretreatment before electrophoresis. This structure is a hollow tubular shape, which makes the casting process difficult. Traditional sand core casting results in a large surface roughness and is prone to casting defects. Therefore, this solution recommends using more advanced processes such as soluble cores, which can clean the cores thoroughly and ensure the roughness of the inner wall.

The cylindrical structural component 1 can be sealed by connecting the mounting component 3 and the connecting component 2. The air intake and exhaust of the cylindrical structural component 1 can be controlled by the setting of the control component 4, and drainage can also be performed by the control component 4. This device has effective reliability in terms of sealing, corrosion resistance and cleanliness.
