in addition, in the metal casting process, the presence of air in the cavity 3 may cause the work piece to suffer from blowholes, surface defects, internal structural changes in the metal, and abnormal flow of molten metal:
air holes: air is trapped in the metal during casting, forming pores. The air holes can reduce the density and strength of the workpiece, so that the workpiece is more easily cracked and broken;
surface defects: when air exists, bubbles or air holes may be formed in the metal during the solidification process, so that the defects of uneven surface, air hole scars and the like appear on the surface of a workpiece;
metal internal structure change: air can interfere with the solidification process of the metal during casting, resulting in non-uniform structure, which can lead to inconsistent strength and hardness of the workpiece, thereby reducing its service performance;
abnormal flow of molten metal: when air exists, the flow of molten metal is disturbed, so that incomplete filling or cold insulation can be caused in the casting, and the shape of a workpiece is inaccurate or partially lost;
