Ten techniques for optimizing injection moulding process:
(1) The temperature of plastics should be controlled within the recommended range of material suppliers.
(2) Filling speed is as fast as possible, with fewer segments:
A Separate filling and feeding;
B At the end of filling, only 95-99% of the product was filled.
C In order to reduce the molecular orientation of plastics, the filling rate can be slowed down appropriately.
D Filling stage to ensure adequate pressure.
E Record and keep the filling time consistent.
(3) Switching the filling position to the feeding position at the end of filling;
(4) Pressure and time control for feeding;
(5) Pressure retention should be ensured to last until gate closure
(6) Controlling cooling rate and time:
A Ensure turbulence in the cooling pipe;
B Control the inlet and outlet temperature of cooling water;
(7) No automatic control technology is used;
(8) The plasticizing process is as slow as possible without increasing the cycle.
(9) Back pressure should not be segmented;
(10) If the material property changes, the temperature should not be adjusted to compensate, but the filling speed should be adjusted to compensate.
