2. Alkaline electrolytic polishing process of aluminum: The research of alkaline polishing solution system was carried out, and the effects of corrosion inhibitor and viscosity agent on the polishing effect were compared. The alkaline solution system with good polishing effect of  die-casting aluminum parts  was successfully obtained, and it was obtained for the first time. Additives that reduce operating temperature, extend solution life, and improve polishing results. The experimental results show that adding a suitable additive to the NaOH solution can produce a good polishing effect. Exploratory experiments have also found that the surface reflectance of the aluminum material can reach 90 after DC constant pressure electrolytic polishing with a NaOH solution of glucose under certain conditions %, But due to the unstable factors in the experiment, further research is needed. The feasibility of using DC pulse electrolytic polishing method to polish aluminum under alk...

The design of die castings involves four aspects: a, that is, the requirements of pressure casting on the shape and structure of the part; b. Process performance of die castings; c. Dimensional accuracy and surface requirements of die castings; d .Determining the parting surface of die castings; The design of die casting parts is an important part of the production technology of die casting. The following issues must be considered in the design: the choice of mold parting surface, the opening of the gate, the choice of the position of the ejector pin, the shrinkage of the casting, the dimensional accuracy guarantee of the casting, Prevention of internal defects, requirements related to casting holes, requirements related to shrinkage and deformation, and the size of machining allowances; Second, the design principles of  die-casting aluminum parts  are: a. Correct selection of the material of the die casting, b. Reasonably determine the dimensional accuracy of...
