Injection molding machine melt when the screw speed is particularly slow, what is the reason for the oil pound pressure is small?

Answer:

First, check the adhesive motor, the small return pipe is not a big return, and if so, the melt motor is broken

1 temperature is too low,2 pressure and speed is too small3 back pressure is too big4. if other movements are slow, there is a problem with the pressure and speed valve.

1, screw to see the size of the pressure gauge, such as large back pressure is too high or low temperature2, still bad, sol valve stuck, 3MM poke the valve core or remove the cleaning3, to see the small gauge storage speed, low pressure, low system parameter setting4, other movements, if the pressure is small, it is possible when the pressure of the oil pump is small

1, the pressure, velocity (flow) of the sol is set correctly.2. Is the sol correct?.3, the stability of the drum is set reasonable.4, sol solenoid valve is stuck (with about 3MM of the thimble will sol electromagnetic valve side of the valve top into, to see if it can be normal.

1. check how much screw speed is set when the injection machine is set2. is the temperature setting reasonable? If the solution temperature (barrel temperature) is unreasonable, and the fluidity of the compound is not good, it will appear because of friction, speed is very slow.The above should be the oil pump problem
