Now there are children’s toys, industrial supplies, daily necessities, medical equipment, etc., have you noticed that their appearance colors are more beautiful than beforeThe two colors are wrapped together, it is very beautiful, and the hand feels very good, thisJustTwo-color mold injectionThe result of the molding process.So Two-colorMold BeHow is it injection molded?Let’s talk about this topic next.
Two-color mode Ingredient In fact, two plastic materials are injected on the same injection molding machine, and the injection molding is divided into two injections, but the product is only ejected once. The first injection molding is the half product of the product.In the injection molding of color A, the quality of the A semi-product is directly related to the problem of the B color encapsulation. If the A product is not well laid, then the B color injection molding will produce flash, which affects the appearance of the product.Therefore, B-color products must ensure the precision of the mold.Because the product sealing position is directly A color product.Moreover, the speed of the last stage of the B-color injection molding machine is definitely slow, and the injection molded product achieves perfect results.
Two-color moldInjection moldingRoughly divided into two categories:
1. Mixed colors and two colorsInjection mold
That is to say, the two nozzles of the injection molding machine alternately inject materials of different colors into the same cavity to form colorful products without obvious boundaries.
2. Double-layer two-colorInjection mold
That is, two two nozzles inject the two materials successively to form a two-color product with obvious boundaries. The first nozzle injects the material into a small cavity and then forms it. Then the mold is opened but not ejected. After the mold is rotated 180 degrees The mold is closed, and then the second nozzle injects another material into the large cavity that already has the first material, so that the two materials are stuck together and the mold is ejected for the second time.
