Cable making problem in production and how to resolve (2)
- Apr 29, 2018 -

Often there is some problem in ordinary cable extrusion, how to resolve these problem very important for finished cable quality.


Cable making problem , reason and resolution:

(6) Hole in the surface

Reason:

Material plasticization is not good; Conductor (core wire) are uneven or partially protruding, with water, oil, etc; Plastic uneven thickness.

Solution:

Increase cable extruder temperature; Conductor (core wire) change, processed then go production; Correction of eccentricity


(7)Muscle in the surface

Reason:

Mould is too big; The temperature is too high and the material is too soft

Solution:

Change the tip and die; Adjust the temperature.


(8) Surface bamboo shape

Reason:

Material extrusion speed is uneven;  Capstan speed is unstable; Tip too small; Conductor (core wire) outer diameter not round; Pay-off tension not stable.

Solution:

Check the uneven speed reason; Adjust capstan speed; Change new tip; Change conductor (core wire); Adjust pay-off tension.
