The definition of two-color mold two kinds of different plastic materials are injected on the same injection molding machine, divided into two molding, but the product only comes out of the mold once. Generally this kind of molding process is also called two-color mold injection processing, which is generally completed by a set of molds.
The two-color mold may not be unfamiliar to us. Sometimes we are using some electronic products or instruments. You will find that their shell has a feature. The color on the shell is not the same, and it will not fade for a long time. It always keeps the original appearance. The appearance is still so gorgeous and beautiful, and it has a good handle and environmental protection.
So the difference between the two-color mold and the general plastic mold is here. The general plastic mold has only one color, and the two-color mold has two colors, which are made of two different materials through two-color injection molding, while the general plastic mold is made of one material injection molding. The reason why the two colors of the shell of the two-color mold are fresh and do not fade.
The general plastic mold wants to finish two or more colors, it is necessary to finish it by spraying the secondary processing technology, paint and simple color fading, not environmental protection, so many enterprises will choose the two-color mold processing to avoid this problem, but the premise is that the two-color mold should have one more set of mold than the general plastic mold, and the cost of making the mold is higher. If the product is large, try The product has a strong competitiveness and a long market, so it\'s not difficult to choose two-color mold, because the cost of general plastic mold products through spray secondary processing technology is also very high.
The two-color mold is becoming more and more popular in the market. This process can make the appearance of the product more beautiful, and it is easy to change the color without spraying, but the cost is expensive and the technical requirements are high. Two sets of moulds are needed for the two-color moulds. The front moulds are different, the two back moulds are the same, and the guide post should not be deviated. In the design, special attention should be paid to the selection of plastic materials for the two-color moulds: for the semi-finished products, it is necessary to select materials with high melting point, and for the finished products, it is necessary to select materials with low melting point.
