This is a study of a medical injection factory-Babylon carried out in order to achieve proper mechanical
and morphological properties, PP has been injection molded by using cold runner injection molding
machine with temperature variation (198, 200, 203……2200C) for ten samples. The physical and mechanical
properties of PP product were examined. It has been found that the Shore hardness decreases
linearly with injection molding temperature increasing. The tensile strength has a similar behavior to
the hardness. However, it has been found that the MIF (Melt Index Flow) rates increases with the
increase of injection molding temperature. The density of PP has been found for both virgin PP and
the samples, it has been found that the density decreases with increasing operation temperature. FTIR
(Fourier Transmission Infrared) spectra were taken for both samples with high and low operation temperature.
Besides the SEM (Scanning Electronic Microscopy) test shows the difference in the morphology
of the product surface and the PP product at high and low operation temperature. Moreover,
for all these properties, the PP product exhibits good mechanical properties (hardness, tensile strength,
density) for the samples produced at temperature lower than 2070C. While the physical properties such
as MIF improved with injection temperature increasing, additionally, the SEM images show that the
sample produced in low temperature have surface damage
