Possible causes of problems: (1) Insufficient injection speed. (2). Plastic shortage (3). Screw cushion is not left at the end of travel. (4). Change of running time. (5) The shooting cylinder temperature is too low. Insufficient injection pressure. (7) The nozzle is partially sealed. The heater outside the nozzle or shooting cylinder cannot operate. (9) Injection moulding time is too short. (10). Plastic is attached to the throat wall of the hopper. (11). The capacity of injection moulding machine is too small (i.e. injection weight or plasticizing capacity). (12). The mould temperature is too low. (13). The antirust oil of the mould was not cleaned. (14). The check ring is damaged, and the melt flows backwards.
Solutions: (1) Increase injection speed. (2). Check the amount of plastic in the hopper. (3) Check whether the... less
