How is the two-color mold injection molded?

Now there are some children's toys, industrial products, daily necessities, medical equipment, etc., have you noticed that they have a more beautiful appearance than before. The two colors are wrapped together, very beautiful, and the hand feels excellent. This is two-color injection molding. The result of the molding process. So how is the two-color mold injection molded? Next, let's talk about this topic.

Two-color molds are actually injection molding of two plastic materials on the same injection molding machine. The injection molding is divided into two injections, but the product is only ejected once. The first injection molding is the semi-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 products. 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 mold injection molding can be roughly divided into two categories:

1. Mixed-color two-color injection mold

That is, 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-color injection 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.

With the development of the economy and the advancement of technology, the use of two-color mold products has become more and more widely used, and more and more people love them. Therefore, two-color molds are increasingly favored by many companies. If you are interested, welcome to inquire for more.
