统分析、过程能力研究、因素试验等方法，对此四个要因进行分析与研 究，从而确定挤塑参数是影响火花击穿的主要因素。 运用正交试验及方差分析方法确定挤塑参数中影响火花击穿的关键 因素，并最后通过JMP 统计软件确定最佳挤塑工艺窗口。 关键词：火花击穿，挤塑，质量改进，正交试验，方差分析 QUALITY IMPROVEMENT OF LOW-VOLTAGE AUTOMOTIVE WIRE FLRY WITH THIN INSULATION THICKNESS ABSTRACT Quality management aiming at process is the core of notion on quality management system standard (ISO9000-2000 version). Quality improvement of process is the activity where the process affecting quality is found and improved, and the expected object is realized, and that is a section of continuous improvement. It is perpetual quality improvement for each process that constitutes continuous quality improvement activities of an organization, and continuous improvement is entire goal of an organization. FLRY, which apply in electronic and circuit control for Germany brand’s motor vehicles, is a type of low-voltage road vehicles single core cable with thin PVC insulation wire in Germany standard. In this paper the key process of FLRY is core product in Suzhou Draka cable Co. ltd has been studied, and analyzed the quality approach and method for FLRY product with thinking of continuous improvement in quality. Investigation proves that optimization of extrusion parameter can reduce effectually the spark breakdown of FLRY product, which will improve directly quality of FLRY product。The major works covers as below items in this paper: 2 Verify FLRY 0.35mm is improvement object by analyzing spark breakdown rate, sales, and output of each size product of FLRY product. 4 group factorshuman, PVC color compound, conductor, and extrusion 2 parameter will effect spark breakdown of FLRY 0.35mm by fish bone analysis. The group factor of extrusion parameter is major factor by further study and confirmation.
