Daily maintenance work for plastic extrusion production line:


(1) Often check purity of the plastic material, not allowed sand or metal powder etc mixing inside and enters the barrel;


(2) Check lubricated part, apply lubrication oil, bearing position working temperature could not be over 50 centigrade degree;


(3) Start screw at low speed, and turn up the speed after working for some time;


(4) Barrel needs enough time for heating and heat preservation, production under temperature which is lower than technology requirement is not allowed;


(5) Screw running time when there is no material in the barrel is not allowed to be over 2~3min;


(6) Check swing change of indicator of screw motors amp meter, if motor overload work for long time, pls stop machine and eliminate the problem;
