| 摘 要： | 为了研究注拉吹工艺参数对制品性能的影响，利用POLYFLOW软件模拟分析了塑料瓶的拉伸-吹塑过程，预测了成型瓶子的厚度分布，并与实测值进行对比。结果表明：改变拉伸速率，对瓶坯的厚度分布有很大的影响，速率过大或者过小都会产生不利的影响；模拟计算对于成型瓶子最终的厚度分布有较好的预测能力。

| Abstract: | Numerical simulations were performed on POLYFLOW software to study the influence of the injection-stretch-blow molding process of bottles on features of the product.Results showed that profiles of the thickness were greatly influenced by stretching speed; both high speed and low speed influlenced the thickness adversely.It was found that the thickness of bottles was well predicted by computer simulation. |

| Keywords: | injection-stretch-blow molding process thickness distribution parison computer simulation |
