Two-color mold in life application scope
General definition of two-color injection mold: two plastic materials are injection molded on the same injection molding machine in two parts, but the product only comes out of the mold once. Generally this molding process is also called two-material injection, which is usually completed by a set of two-color molds and requires a special two-color injection molding machine.
Two-color mold products are loved by more and more people because of their appearance performance, and we can see a lot of two-color mold products in life, so what are the types of two-color molds applied in life?
In recent years, with the increasing popularity of two-color mold in industrial life, the rapid development of science and technology and the general and engineering plastics in the strength and precision of the continuous improvement, injection mold products in industry and the application of life is also expanding, such as: household appliances, daily necessities, instrumentation, construction equipment, automotive industry, medical equipment and many other fields, the proportion of injection mold products The proportion of injection molded products is increasing rapidly. A well-designed plastic part can often replace several traditional metal parts. The trend of plasticization of industrial injection mold products and two-color mold products for daily use is rising.

1, part of the products need plating, such as cell phone keys, plating part to do ABS, do not need plating part is made of PC or other materials, here you need to use the two-color mold.
2, like cell phones, MP3, MP4 and other digital electronic products need two-color integrated molding shell will also be used to two-color mold injection molding process to produce.
3, due to the functional needs of the product must use two-color mold, such as power switches, cell phone keys, car switches, etc., these products are to go to the LED part to be able to transmit light, so it will use two-color molding process.
4, product feel, appearance decision, for example, some handheld equipment products like mouse, electric drill shell, etc. using RUBBER feel and appearance will be more comfortable, for the product market competition is more favorable, in addition, some two-color key products, the use of two-color injection molding process to produce the appearance of both beautiful and do not worry about being worn out.
Two-color mold in the injection molding process need to pay attention to: injection molding tool is a tool for the production of plastic products. It consists of several groups of parts parts, and this combination has molding cavities within it. When injection molding, the injection mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity and cooled and shaped in the cavity, then the upper and lower molds are separated, and the products are ejected from the cavity and leave the mold through the ejector system, and the two-color mold is closed again for the next injection, and the whole injection process is cyclic.
