説明

A quantitative study of the appearance quality of weld-line which had been previously examined by human eyes was performed.<br>ABS (Acrylonitrile-Butadiene Styrene) dumbbell samples were molded with a weld-line in the middle and the weld-line gap depths were measured by a surface roughness measuring instrument. An automatic-search multiple-regression analysis for optimum factors was applied in order to generalize the test results.<br>The results are summarized as follows;<br>(1) It became clear that weld-line quality could be quantified by weld-line gap depth.<br>(2) A reliable equation relating weld-line gap depth, resin viscosity at the weld and cavity pressure was obtained.<br>(3) The allowable limits of variation in molding factors for producing invisible weld-lines (below 1.0μm of weld-line gap depth) were determined using the multiple regression analysis.
