The appearance of the two-color mold is more beautiful than the monochrome mold, easy to change the color without spraying, the disadvantage is that the cost is expensive, high technical requirements:
1, the male mold of the two-color mold is two exactly the same, and the female mold is two different molding respectively.
2, the front and back of the two-color mold must be consistent. This has higher requirements for mold positioning and processing.
3, according to the product data control front die panel thickness, mold thickness, KO hole distance, etc.
4, the two-color mold in the second injection molding, to avoid the second die insertion injury the first time has been formed product glue position, you can design a part of the avoidance. However, the strength of each sealing position must be carefully considered.
5, when injection molding, the size of the first injection molding product can be slightly larger, so that it can be pressed more tightly with another male mold during the second molding to achieve the role of sealant.
6, before the front and back plate closing, pay attention to whether the front die slider or inclined top will be reset first and crush the product, we must find A way to make the A and B plate closing first, and then the front die slider or inclined top can be reset.
Two-color mold is formed by mixing two materials together. These two kinds of molten material must have a good combination strength, in order to ensure a good combination strength, must first conduct a combination performance test, confirm the combination of qualified before being put into production. ​
