Finished Mucous Membrane Possible Causes And Treatment Countermeasures
(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.
