The two-color mold is made of two plastic materials on the same machine and can only be molded in two parts. However, products are usually only disposable molds, and this process is also called bi-material injection molding. Usually, it can be completed by a set of molds, and the production machine needs to be specially manufactured. In addition, it is becoming more and more popular in the market and gradually being welcomed by consumers. The appearance of product technology has been adjusted a lot to become more beautiful. It’s easier to change the color, no need to brush. However, its undesirable features are relatively high prices, high technical requirements and more challenges in the future.
The two shapes of the two-color mold are different, forming one product respectively, but the two shapes of the two models are exactly the same. The forward and backward rotation of the model manufacturing must match exactly, and this inspection must be completed when this work is carried out. This requirement is relatively high. Another thing to pay attention to is the processing thickness of the panel. Please carefully observe the model before and after as other basis. Pay special attention to whether the demoulding of soft saliva is possible. When designing the second injection molding, the size will be slightly larger.
Because the two-color mold can be compressed with another template during the second molding, the sealing effect can be achieved. In addition, whether the product will be crushed and deformed by returning to its original position. If this happens or is possible, we must find a way to change it, not just ignore it arbitrarily. Arrangements for waterway transportation should be as uniform and consistent as possible. Try not to make soft injection glue, because it is not easy to deform and will last longer.
