The effect of aluminum alloy die castings after cleaning by shot blasting machine
The effect of the aluminum alloy die castings handled by the shot blasting machine:
(1) Shot blasting thoroughly sorts out high yield. Because it is appropriate to use the new type of shot blaster with a projectile volume of 110 ~ 260 kg / min and a projectile velocity of 50 ~ 75 m / s, the projectile can be completely cleaned up in a few minutes. For large-volume or large-sized work pieces, multiple shot blasting devices can be used for shot blasting.
(2) Thoroughly finishing, adding color and finishing to the appearance of parts. After the shot blasting treatment, the attachments, thin edges, fins, and spots on the surface of the workpiece can be removed, the scratches can be eliminated, and the workpiece can be flashed in the original color.
(3) Eliminate the external stress concentration. During the cooling process of parts, due to uneven wall thickness, the cooling rate is not exactly the same, causing stress concentration to appear on the surface. After thorough blasting, it can improve the appearance of the group structure, reduce the concentration of external stress (tensile stress), increase fatigue strength, and slightly increase the external hardness.
(4) Increase the appearance of pleasure. Because the projectile is a spherical pellet, a small concave hole sprouts on the workpiece, which is like the surface of a ball. It is like a spherical mirror. Under the light mapping, like a star, it shines.
(5) Increasing the appearance of sticky eyesight. After the shot blasting, the finish can reach Ra 1.6 ~ 6.3 um. The size of the surface or the surface of the object is greatly increased. At the same time, the surface dirt is eliminated, because the adhesion of the paint or other paint pieces is greatly strengthened.
(6) The process is simple and the investment is saved. Dry blasting is used because it is considered appropriate, and it is equipped with a dust removal system, because this blasting can be transferred to the next process after being completely sorted out, eliminating the cost of the equipment required for washing and drying after liquid blasting.
