压铸零件常见质量缺陷分析与对策

介绍了压铸生产中铸件常见的质量缺陷。基于压铸工艺的加工特点,详细分析了压铸件气孔、气泡、流痕、印痕、缩孔、欠铸、裂纹等典型缺陷的形成机理,以及产生和影响的主要因素。结合零件的结构、材料、模具、压铸工艺参数和压铸设备,从生产实际要求出发,提出了解决问题的思路、对策和消除缺陷的具体措施。

Analysis and Solutions of Primary Defects for Die-casting Parts

Die casting production of the common quality defects were introduced.Die-casting process based on the processing characteristics,a detailed analysis of casting porosity,bubbles,flow marks,prints,shrinkage,due to casting,cracks and other defects in the formation of the typical mechanism,and the generation and main factors.Combining parts of the structure,materials,molds,die casting process parameters and equipment,from the actual production requirements,and proposed solutions to those problems,strategies and concrete measures to eliminate defects.
