What is the difference between two-color molds and ordinary molds?

Two-color molds may not be unfamiliar to everyone. Sometimes when we use some electronic products or instruments, you will find that their shells have a special feature. The colors on the shells are different, and they will not fade for a long time. The original appearance, the appearance is still so bright and beautiful, and the operation feels good, and it is environmentally friendly.

So the difference between two-color molds and ordinary plastic molds is here. Common plastic molds have only one color, while two-color molds have two colors. They are formed by two-color injection molding from two different materials, while ordinary plastic molds have two colors. It is injection molded from one raw material. The reason why the two colors of the shell of the two-color mold are fresh and not fading.

If ordinary plastic molds want to achieve two or more colors, they must be finished by spraying secondary processing technology. The paint is easy to fade and is not environmentally friendly. Therefore, many companies choose two-color molds to avoid this problem, but the premise is Two-color molds have one more set of molds than ordinary plastic molds, and the cost of molding is higher. If the product is large in quantity, the trial product has strong competitiveness and long-term market. It is not bad to choose two-color molds, because The cost of ordinary plastic mold products through the secondary processing process of spraying is also very high.

Two-color molds are becoming more and more popular in the market at present. This process can make the appearance of the product more beautiful, easy to change the color without spraying, but it is expensive and requires high technical requirements. Two-color molds require two sets of molds. The front mold is different, the two rear molds are the same, and the guide post should not be offset. Special attention should be paid to the design of the plastic material for the two-color mold: semi-finished products. The material with high melting point must be selected, and the material with low melting point must be selected for the finished product.
