“…in work [20][21] authors investigated the influence of the injection and mould temperature on the mechanical and physical properties of mouldings with weld line areas. in turn, in paper [22] research related to the impact of processing parameters: injection speed, injection pressure and mould temperature on changes in strength and degree of crystallinity of samples with weld lines. with the optical microscope the thickness of the weld lines were also measured.…”

AnAlysis of the influence of the Mould teMperAture in the Weld line AreAs on strength of the injection Mouldings the weld lines that occur in injection mouldings are critical areas on which depends on the strength of the mouldings. the flow of the material in the injection mould takes place through the gate and then gradually in the mould cavity. Depending on the shape of the formed object, the weld line may or may not occur. in the case of spreading of plastic streams or bypassing obstacles in the form of cores in the mould, the joining lines run down. most often, the strength of the moulded part is the lowest in these areas and the resulting lines can cause cracking. the aim of the research presented in the publication was to evaluate the properties of particular parts of mouldings obtained from an experimental injection mould equipped with 4 weld line areas. the tests were performed using the method of thermal analysis by Dynamic mechanical analysis Dma. tensile tests were performed on the parts with weld areas and the maximum crack force was determined. the morphology of the obtained fractures was observed using an optical microscope.
