It can be easily seen the "air trap" of the transparent part, but can also be found in the opaque plastic. This is related to thickness and is often caused by shrinkage of the plastic away from the center of the injection.
Possible reason of the problem
路 The mold is not fully filled.
路 Abnormal operation of stop valve.
路 The plastic material did not dry completely.
路 The inject speed is too fast.
路 Some special materials are produced with special equipment.
路 Increase the amount of injection.
路 Increase injection pressure.
路 Increase the time of screw forward time.
路 Lower the melting temperature.
路 Reduce or increase injection speed.(for example, for amorphous plastics, an increase of 45%).
路 Check that the check valve is broken or not operating.
路 The drying conditions should be improved according to the characteristics of the plastic, so that the plastic completely dry.
路 Appropriately reduce the screw speed and increase the back pressure, or reduce the injection speed.
