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.

Abstract:

In gas-assisted injection molding (GAIM) products, air bubbles at the airway wall are important factors affecting the mechanical and optical properties of plastic parts. The influence of GAIM process parameters on the formation of bubbles on the inner wall of plastic products was studied by quantitative test method, the relationship between process parameters and bubble formation law was discussed, and the reasons for bubble formation on the inner wall of AIM products were revealed. The results show that reducing the melt temperature, gas injection pressure and holding pressure and shortening the gas holding time can effectively prevent the formation of airway wall bubbles.
