摘要
气体辅助注射成型(GAIM)制品中,气道壁处的气泡是影响塑料制件力学和光学性能的重要因素.运用定量试验方法,就GAIM工艺参数对塑料制品内壁气泡形成的影响进行了试验研究,探讨了工艺参数与气泡形成规律的关系,并揭示了GAIM制品气道内壁气泡形成原因.结果表明:降低熔体温度、气体注射压力及保压压力,缩短气体保压时间均可以有效地防止气道壁气泡的形成.
In the gas-assisted injection molding,foaming structure in the gas channel region is a Key factor affecting the mechanical and optical performance of the GAIM part.An experiment was carried out to study the effects of the processing conditions on foam formation in the gas-assisted injection molding,using quantitative analysis method.The relationship between the processing parameters and foam formation on the gas channel wall was discussed and the reasons leading to foam was analyzed.The results reveal that ...
