摘要
概述注塑制件熔接痕的形成及其危害,主要讨论塑料注塑制件中熔接痕的形成机理、熔接痕影响区的形态结构、影响熔接痕处性能的因素,以及工艺条件、模具几何条件对熔接痕处性能的影响等。在注塑模流动模拟的基础上,结合计算机图形学知识,利用计算机自动实现了注塑中熔接痕的自动识别。
The formation and damage of weld mark in the injection part are reviewed. The forming mechanism and morphology of weld mark are discussed; the influencing factors on the performance of weld mark are introduced. The locations of weld mark are predicted by computer based on flow simulation. Implementation of such an algorithm is based on the computer graphic knowledge and flow simulation of the injection molding.
