Waste PP PE PVS ABS plastic film/pipe/ recycling extruder Machine

Inner Screw

Four reasons leading to insufficient extrusion of plastic pelletizers: 1. Temperature reason To increase the temperature of the barrel and nozzle, check the millivoltmeter, thermocouple, resistance electric heating ring or far-infrared heating device and heating system, increase the mold temperature, and check the mold temperature control device. 2. Mould reason Plastic pelletizer runner is too small, gate is too small, nozzle hole is too small, gate position is not reasonable, gate number is not enough, cold slug hole is too small, exhaust is insufficient, injection cycle caused by mold is abnormal. 3. Equipment reason The hopper is interrupted, the neck of the hopper is partially or completely blocked, the feeding amount is insufficient, the feeding control system is not operating normally, the plasticizing capacity of the injection press, and the injection cycle caused by the equipment are abnormal. 4. Reasons for extrusion conditions The injection pressure of the plastic granulator is too low, the injection pressure loss during the extrusion cycle is too large, the injection time is too short, the injection total pressure time is too short, the injection rate is too slow, the flow in the cavity is interrupted, and the filling rate is not equal , Abnormal injection cycle caused by operating conditions.
