Blow Hole Defects Reducing Methods for Die Castings
减少压铸件气孔的基本方法
The test results show that the zinc coat loss can be reduced as pass draughts increase by raising work cone angle rationally and reducing the bearing length, but which has not obvious effect on the mechanical properties of finished steel wire and the service life of die.
试验结果表明部分压缩率增大时,合理增大工作锥角度、减少定径带长度,可减少锌层质量损失,而对成品钢丝的力学性能和模子寿命影响不明显。
it has important value in reducing the drawing number and the processing cost, achieving better economic results and improving technical standard of drawing die of the thin stainless steel at home.
对减少拉深次数,降低加工成本,取得良好的经济效益,以及提高国产薄壁不锈钢拉深模具技术水平有重要的价值。
Power sharing can reduce die size by reducing the number of channels.
电源共享能通过减少通道数来减小芯片面积。
