塑料嵌入金属产品毛边产生的原因及改进措施

Reasons and improvement measures for burrs in plastic products with metal-insert

分析了采用金属嵌件模具成型的产品极其易产生毛边的原因,对制件的注塑压力、注塑速度及温度的成型条件进行了优化,试模的结果是产品的不良率从17.5%下降到7.8%。运用"五W分析法",采用弹簧运动机构放置嵌件,彻底消除了金属产品的毛边,大大地提高了生产效益。

Reasons for generating burrs easily in plastic products molding with metal-insert mould was analyzed and molding conditions such as injection pressure,injection speed and temperature were optimized.Mould trial shows that the defective rate decreased from 17.5％ to 7.8％.The spring institution was used for placing the metal insert according to ＂five W analysis＂,thus eliminating burrs around inserted metal and greatly improving production benefit.
