In the daily production of cable extruder, we often encounter a variety of quality problems. Here are some reasons and treatment methods for poor cable plasticization in the production process of the extruder:
1. The surface is powdery, dull and granular.
Reason: the fuselage temperature is not enough; The head temperature is too low; The screw speed is too high.
Treatment method: properly increase the temperature of the cable extruder body; Appropriately increase the temperature of the head; Reduce the speed of the extruder
2. The surface is dull
Causes: organ temperature is too low; Wire diameter is too small; The mold is too big.
Treatment method: appropriately increase the head temperature; Measure the outside diameter and match the corresponding die sleeve according to the line diameter.
3. Bubbles on the surface
Reason: There is water and oil in the conductor (core); Wet plastic; High fever
Treatment method: clean water and oil stains for reproduction, heating with preheater; Dry plastic; Properly reduce the temperature of the cable extruder.
