Precautions for rubber injection molding machine extruder:
1. People should not be in front of the mold before the plastic is extruded.
2. Start at low speed, run idling, check whether the screw is abnormal and the motor current, etc. The instrument is overloaded and the pressure gauge is normal (the idle time of the machine should not be too long, the shorter the better, to prevent the friction between the screw and the screw and the friction generated by the barrel, scratching the barrel or screw, the screw running time should not exceed three minutes.)
3. Gradually add a small amount of material. When the plastic is extruded into the die, the screw speed can be brought up to normal operating speed before the batch is fed.
4. After extruding the plastic, the extrudate should be slowly introduced into the cooling and traction equipment, and the equipment should be opened in advance.
The above four points are the precautions for rubber injection molding machine extruder
NOTE: Do not turn on the cold or turn on the cold car, because the extruder is not yet "hot" (i.e. the plastic in the extruder barrel has not fully reached the specified temperature, the viscosity of the plastic is very high), then drive, especially the old style extruder machine, the screws may be damaged. Newer extruders are often equipped with torque overload protection. A reliable and most effective method is to turn the connecting parts by hand three times when the temperature rises to the desired temperature before driving. After a smooth rotation, the third circle on the right can be opened. If you can't turn it smoothly, you just can't open it.
