Common sense of PET raw materials that need to be paid attention to in the injection molding process
一、Before molding, the plastic must be fully dried. After the material containing moisture enters the mold cavity, it will cause silver tape-like flaws on the surface of the part, and even hydrolysis at high temperatures, resulting in deterioration of the material. Therefore, the material must be pretreated before the molding process, so that the material can maintain the proper moisture.,dig-pink-volleyball-jerseys
volleyball-frankfurt-oder,1.Mold temperature affects the molding cycle and molding quality. In actual operation, it starts from the lowest appropriate mold temperature of the material used, and then adjusts it appropriately according to the quality situation.
2.Correctly speaking, mold temperature refers to the temperature of the cavity surface when molding is performed. In mold design and molding engineering condition setting, it is important not only to maintain a proper temperature, but also to make it uniform Distribution.,fsu-volleyball-gear

4.Increasing the mold temperature can obtain the following effects：,2008-australian-open-final

Although about 60~85% of the melting of plastic is due to the heat generated by the rotation of the screw, the melting state of the plastic is still greatly affected by the temperature of the heating cylinder, especially the temperature near the front of the nozzle-the temperature of the front is over When it is high, it is easy to cause dripping and wire drawing when taking out the parts.,basketball-rules-with-modal-verbs
