Reasons And Solutions Of Uneven Thickness And Skew in Extruder

1, produce uneven thickness and bamboo shape phenomenon
(1) Uneven thickness of cable outer diameter due to screw or traction instability.
(2) Due to the sudden instability of traction, the formation of cable plastic, etc., is bamboo.
(3) The mold selection is small, the outside diameter of semi-finished products changes greatly, resulting in uneven thickness of the plastic layer of the cable.
2. Causes of uneven thickness and slub shape
(1) Uneven speed of retracting and releasing lines or traction.
(2) The outside diameter of semi-finished products changes greatly, and the mold selection is inappropriate.
(3) screw speed is unstable, the main motor speed is uneven, the belt is too loose or slip.
3. The method of excluding uneven thickness and slub shape
(1) Often check whether the speed of screw, traction and pay-off is even.
(2) The mold selection should be appropriate to prevent the phenomenon of pouring glue.
(3) Often check the operation of machinery and electrical equipment, and find the fitter and electrician to repair the problem immediately.
