The project elaborated design of optimization venting of molds exhibiting bubbles or low quality weld lines. Based on a literature study of the injection mold venting, the use of vacuum venting, namely the VACUUMJET system of the Spanish CUMSA manufacturer, has been proposed. The experiments proved the elimination of bubbles in the part and the marked improvement of visual quality of the weld lines. The effect on the closing force was not confirmed. The use of the system is more economical for larger batches production, or when high quality parts are required that allow price increasing. |
