| 摘 要： | 通过对现有注塑、气辅设备的改造，时气辅共注射成型工艺进行了实验研究。考察了材料流变性能、注射量和气体注射延迟时间对材料层厚分布及气体在熔体中穿透的影响规律。实验表明，芯皮层材料层厚分布主要受芯皮层熔体粘度比和芯皮层注射量的影响；气体在熔体中的穿透主要受熔体的总注射量和注气延迟时间的影响。 |

| Abstract: | Experimental investigation on gas-assisted co-injection molding process, an innovative plastic injection molding process, is conducted based on the improved equipments. The influences of the rheological properties, injection content and delay time of gas injection on material distribution and gas penetration are investigated. Experimental results show that material distribution is influenced mainly by viscosity ratio of core melt to skin melt and injection content of them. Gas penetration is influenced by the total injection content of melt and delay time of gas injection. Some conclusions which can be used to guide practical applications are drawn. |
| Keywords: | gas-assisted co-injection molding experimental investigation plastics |
