| Abstract: | The gate location and quantity were determined based on the function of the best gate location and filling analysis of Moldflow software. The optimal combination of smaller injection moulding shrinkage mark index was determined by orthogonal experimen-tal method; the influence of injection moulding process parameters on the shrinkage mark in the plastic part were investigated and different process parameters were also analyzed. The results show that the shrinkage mark index can be decreased with the reduction of melt and mould temperature and the increase of packing pressure and injection time. |
