| Abstract: | Influence of weld lines is important to the impact properties of the modified polypropylene products.Orthogonal experiments were adopted to confirm injection process parameters for such mechanical properties as impact resistance of the modified polypropylene injection-molded parts in weld lines.The causes and effects of such injection process parameters,including melt temperature,mould temperature,the velocity of mould filling,injection time,injection pressure,packing pressure and post-treatment conditions,on the appearance and property of the weld lines were analyzed to improve process parameters for better injection. The specifications of cross section in weld lines of the products were analyzed to illustrate the theory of fracture. |
