Finished Mucous Membrane Possible Causes and Treatment Countermeasures

- Dec 04, 2018-

(1) The filler is too full to reduce the injection dose, time and speed;


(2) The injection pressure or the barrel temperature is too high to reduce the injection pressure or the barrel temperature;


(3) The pressure keeping time is too long to reduce the holding time;


(4) The injection speed is too fast to reduce the injection speed;


(5) Uneven feeding causes partial saturation to change the size or position of the overflow;


(6) insufficient cooling time to increase the cooling time;


(7) The mold temperature is too high or too low to adjust the mold temperature and the relative temperature on both sides;


(8) There is a mold undercut in the mold to repair the mold to remove the chamfer;


(9) The multi-cavity mold inlet is unbalanced, or the inlet of each single-hole mold unbalances the plastic flow, as close as possible to the main channel;


(10) Poor design of the demoulding part of the probe tube provides a sufficient air passage;


(11) The screw advancement time is too long to reduce the screw advance time;


(12) The mold core is misaligned to adjust the mold core, and the "retraction" angle is used to lock the mold;


(13) The surface of the mold is too rough to light the surface of the cavity, and the release agent is sprayed.
