How does precision die casting factory deal with surface defects of aluminum alloy die casting
How does precision die casting mold factory deal with the surface defects of aluminum alloy die casting parts? In the production of aluminum alloy die casting parts, some small particles on the surface of die casting parts have different degrees of adsorption on the surface of the casting, and the defects are only slightly felt, which is difficult to find without careful study and observation or hand touch
Precision die casting die factoryhow to deal withAluminum Alloy Die CastingpieceSurface defects. In the production of aluminum alloy die castings, there are some small particles on the surface of the die castings adsorbed on the surface of the castings to varying degrees, and the defects are only slightly felt, which is difficult to find without careful study and observation or touch. The impact and oxidation, electrophoretic painting and spraying on the surface beauty of the castings reduce the production management efficiency and yield, which is a fatal defect of high-end decorative profiles. Therefore, the formation mechanism of the defects Data analysis can be carried out. In the production and living practice of extrusion products, we constantly develop the ability to observe and analyze, summarize its causes, and take corresponding measures in a timely manner, It is to reduce or eliminate the impact of using effective hand die casting dies with such technical defects Span>
In extrusion production, the die casting die works under high temperature and high pressure. Under the influence of pressure and temperature, the die casting die produces elastic deformation Span>Precision Die Casting Mold FactoryHow to deal withaluminum die castingpiecesurface defects,During the formation of impurities, particles are constantly taken out by the profiles and adhered to the surface of the castings, producing" adsorbed particles ". With the increase of impurities, the die-casting die produces instantaneous rebound, forming bite defects. If there are many impurities, they cannot be pulled out by the castings. When the die-casting die rebounds instantaneously, the impurities will not fall off, the casting surface, bright strips, profiles tear, die plugging and other problems.
Precision Die Casting Mold FactoryHow to handleAluminum alloy die-castingpieceThe defects on the surface of the die casting die are basically plane dies. When the die casting rod does not peel, the surface and internal impurities of the casting rod accumulate in the metal flow of the die casting die, and the impurities change constantly. Some impurities are accumulated in the deformation space of the working belt through the normal flow of metal.
