Precision injection moulds how to prevent the formation of stripe defect?
As is known to all, precision injection moulds streaks defect is a very serious thing, he will directly affect the accuracy of injection molding processing, serious still can cause the abandonment of injection moulds, so we must attach importance to it. So, how can we avoid this kind of defect?
Precision injection moulds the correct design, elaborate processing, reasonable repairing mold, timely nitride is the key to preventing stripe defect.
Precision injection moulds should be strictly in accordance with the drawing requirements processing, especially pay attention to improve the tap hole surface luminosity and die bridge a drop of water, improve the state of solid metal flow, reduce friction heat; For generating the organization the injection mold of stripe extrusion, repair the die should be to the scene to understand plastic injection mold discharging situation, determine the correct repair method; Repair die personally observe the state of the material discharging moment than material discharging head to determine the effect of repairing mold material is much better; Nitrogen injection mould in accordance with the provisions in a timely manner, to ensure that the solid metal reasonable flow state.
Precision injection moulds right design, reasonable layout of the tap hole, the reasonable work zone length, and the length of the transition change, drop shape mould bridge, the reasonable weld Angle, make the solder point fall in the weld chamber of the plane, the mould core in stiffness, strength, deepen the depth of the weld chamber or enlarge the area of weld chamber, using "sunken bridge" when necessary, is the basis of preventing stripe defect.
