(3). Check whether the injection schedule is set correctly and change it if necessary.

(4) check whether the check valve is worn or cracked.

(5) check whether the operation is stable.

(6) increase the melt temperature.

(7) increase back pressure.

(8). Increase the injection speed.

(9). Check whether the nozzle hole has foreign body or plasticized plastic.

(10). Check whether the energy output is correct with the ampere meter in all the heaters.

(11) increase the screw forward time.
