We shouldn’t start the injection machine if the temperature of the material barrel hasn’t reached the preset temperature. Screw of injection machine can be handled after the temperature of electric heating reaches to the set point about 30 minutes.

Every time after the injection molding machine have exceeded half an hour, it will be better to shut up the blanking mouth and clean up the plastic in the material barrel. And then set the heat preservation.

Avoiding the foreign material dropping into the material barrel to damage the screw and barrel material. Prevent the flifler and sundries from dropping into the hopper. If process recycling material, it needs magnetic hopper prevent scrap iron from entering into material barrel.

Avoid the screw idling and skid.

When using the new plastic, we should clean up the excess material which in the material barrel. When using POM, PVC, PA+GF, we should reduce the degradation of the raw material. After the injection machine has stopped, we should use ABS or other degradedmaterial to wash out.

We should prevent the POM and PVC from dropping into the material barrel at the time. Because it may cause serious industrial accident under the melting temperature.
