Injection mold factory: How can precision injection molding molds prevent the occurrence of streak defects?

As we all know, the occurrence of streak defects in precision injection molding molds is a very serious matter, which will directly affect the accuracy of injection molding processing, and even lead to the scrapping of injection molding processing molds, so we must pay attention to it. So, how can an injection mold factory avoid such defects?

Correct design, careful processing, reasonable mold repair and timely nitriding of precision injection molding molds are the key measures to prevent streak defects.

The precision injection molds of the injection mold factory should be processed in strict accordance with the requirements of the drawings, especially to improve the surface luminosity of the shunt holes and the dripping shape of the mold bridge, improve the flow state of the solid metal, and reduce frictional heat; At the same time, the mold repairer should go to the site to understand the discharge of the injection mold and determine the correct mold repair plan; the mold repairer personally observes the state of the profile discharge moment than observing the profile discharge head to determine the effect of the mold repair plan is much better. ; The injection mold is nitrided in time according to the regulations to ensure a reasonable flow state of the solid metal.

The precision injection molding process mold is correctly designed, the distribution holes are reasonably arranged, the length of the working belt is reasonably determined, the injection mold factory and the transition of the length change, the dripping shape of the mold bridge, and the reasonable welding angle, so that the welding point falls on the plane of the welding room , In the case of the rigidity and strength of the mold core head, deepening the depth of the welding chamber or expanding the cross-sectional area of the welding chamber, the injection mold factory adopts "sinking bridge" when necessary, which is the basic measure to prevent the occurrence of streak defects.
