Analysis of quality problems in the Health Products HDPE Plastic Bottle for health products

Die factors

(1) the exhaust vent is too thick and should be reprocessed.

(2) the sliding block is not in place and should be repaired or replaced with a bolt and slider to improve the matching accuracy.

(3) the die inserts are not installed properly, reinstall the inserts and adjust the accuracy of the inserts.

(4) the flow path is unbalanced, and the moduli and impurities should be removed to balance the flow path and clean the raw materials.

(5) the die insert is damaged, and the inserts should be repaired and replaced.

(6) insert block irrigation, repair the mold to reduce the clearance between the die inserts, or the filling switch position increases the dosage to reduce and reduce the pressure and speed.

(7) the mold core and the cavity and each insert shall cooperate with the bad, repair the mold to reduce the mold core and the cavity and the interstitial space between the pieces

Process factor

(1) Health Products HDPE Plastic Bottle too much pressure and too fast. It will cause the expansion mode. In the case of overflow, the filling pressure and speed or the melt temperature should be reduced appropriately to make the viscosity increase.

(2) the pressure pressure is too high, the plastic is forced condensation, the residual stress will appear, which causes the strength to fall, and there is a possibility of overflow, which should reduce the pressure pressure properly.

(3) the temperature of the feeding tube or the heat flow path is too high, the viscosity of the material is too high, the flow is good enough, the temperature can be reduced properly, or the injection pressure can be properly lowered.

(4) Health Products HDPE Plastic Bottle the mold temperature is too high, not only will there be a side of the blade, but also the defect of deformation, which can be adopted to lower the temperature of the chiller or the water of the water, and reduce the mold temperature.

(5) if the injection switch is not in place, the switching position is large or small

Equipment factor

(1) Health Products HDPE Plastic Bottle in the cylinder locking oil cylinder, it should overhaul the cylinder and replace the oil seal.

(2) the columnar column is not parallel, the fixed plate and movable plate are not perpendicular to the movable plate and the locking rod is worn, and the parallel degree of the columnar column is adjusted and the connecting rod sleeve is replaced.

(3) there is not enough clamping force in the machine table, which causes a gap in the parting surface, which should be adjusted to increase the clamping force.

Process factor

(1) Health Products HDPE Plastic Bottle the filling pressure is too high and too fast; It will cause the expansion mode. In the case of overflow, the filling pressure and speed or the melt temperature should be reduced appropriately to make the viscosity increase.

(2) the pressure pressure is too high, the plastic is forced condensation, the residual stresses that can occur, the strength is decreased, and there is the possibility of the overflow, the pressure should be lowered appropriately.

(3) Health Products HDPE Plastic Bottle the temperature of the feeding tube or the heat flow path is too high, the viscosity of the material is too high, the flow is good enough, the temperature can be reduced properly, or the injection pressure can be properly lowered.

(4) the mold temperature is too high, not only will there be a side of the blade, but also the defect of deformation, which can be adopted to lower the temperature of the chiller or the water of the water, and reduce the mold temperature.

(5) if the injection switch is not in place, the switching position is large or small
