Injection molding process how to deal with bending phenomenon? If the injection molding has a bending phenomenon, Yantai injection molding plant for the reasons for the reasons are as follows:
(1) internal injection of excessive stress, can not be eliminated in time.
(2) mold filling speed is too slow, or mold cavity plastic.
(3) plastic temperature is too low or temperature is inconsistent.
(4) injection molded parts in the process of overheating, or its structure is unreasonable.
(5) lack of cooling, or dynamic, fixed mold temperature is inconsistent.
For these reasons, Yantai injection molding plant can take the following measures:
(1) appropriate to reduce the injection pressure, make it appropriate.
(2) injection molding slow cooling, thereby increasing the cycle time, or reduce the screw forward time.
(3) to improve the injection speed or plastic temperature.
(4) use high-quality cooling equipment, so that it can be completely cooled.
(5) appropriate to improve the conditions, so that the mold temperature and mold temperature consistent.
(6) in the conditions permitting, to improve the structure of plastic parts to make it reasonable. |
