Pores and shrinkage cavities: During the die casting process, Because the gas in the molten metal cannot be discharged in time or the metal solidifies and shrinks, Will form pores and shrinkage cavities inside the parts
理由: Improper design of casting system, Improper die casting parameters, Liquid metal with high gas content.
解決
Optimize casting system, Add exhaust channels, Facilitates gas discharge.
Adjust die casting parameters, If lowering the pouring temperature, Increase die-casting pressure, 等.
Degassing of molten metal, Reduce air content.
Surface defects: like flow marks, Cold insulation, Strain, 等, Affects the appearance quality of parts
理由: 粗い金型表面, Die casting speed is inappropriate, Improper use of release agent.
解決
Improve mold surface quality, 研磨.
Adjust die casting speed and pressure, Ensure smooth flow of molten metal.
Choose the right release agent, and use it correctly.
寸法偏差: There is a difference between the actual production part size and the design size
理由: 金型の摩耗, Die casting parameters are unstable, measurement error.
解決
