| 英文摘要: |
| The effects of different processing parameters on sink marks, which occur on the surface of injection moulded parts, have been investigated. An L-16(45) orthogonal array design was conducted to minimize the sink marks of injection moulded polypropylene part. The factors selected in the main experiments were found to be the principal parameters affecting sink mark formation on injection moulded polypropylene part. In this way experimental investigation can help the understanding of the formation mechanism of sink marks, so that the surface quality of the part can be optimized. |
