磁性金属在塑料模设计中的定位应用

Application of Magnet Metal to Holding of Metal Insert Part in Plastics Mould Design

针对某一塑料件产品的模具设计过程中遇到关键尺寸难于控制的问题。采用磁性金属棒对模具中的塑料嵌件进行定位。实际应用表明 ,该设计能很好地控制产品的尺寸精度 ;显著降低废品率 ,取得了很好的经济效益。

To counter the control of the key size of the mould in the mould design for a plastics part,magnetic metal bar was used to the holding of the metal insert part in the mould. The results of practice showed the size of the mould could be controlled accurately by this method,reslting in decrease of reject rate and gaining good economic result in production.
