What are the types of dual color molds used in daily life? In our daily life and industrial production, various injection molding industrial products are often used, ranging from various injection molds for machine tools and plastic casings for machine bodies to small household items and casings for household appliances, all of which are closely related to injection molding. The shape of injection molds determines the appearance of these products, and the quality and accuracy of processing also determine the quality of these products. Due to the different materials, appearances, specifications, and uses of this injection mold product, it is divided into non injection molds such as casting molds, forging molds, die-casting molds, stamping molds, and injection molds.

1. Some products that require electroplating in certain areas, such as mobile phone buttons, the electroplating part is made of ABS, while the parts that do not require electroplating are made of PC or other materials. Here, a dual color mold needs to be used.

2. The outer shell of digital electronic products such as mobile phones, MP3 players, MP4, etc. that require dual color integrated molding will also be produced using dual color injection molding.

3. Due to the functional requirements of the product, it is necessary to use dual color molds, such as power switches, phone buttons, car switches, etc. These types of products require LED parts to be transparent, so dual color molding technology is used.

4. The feel and appearance of products are determined by their appearance. For example, some handheld devices such as mice and electric drill casings will have a more comfortable feel and appearance when using RUBBER, which is more advantageous for product market competition. In addition, some dual color button products, produced using dual color injection molding technology, have a beautiful appearance without worrying about wear and tear.

The general definition of a dual color injection mold is a mold where two plastic materials are injected into the same injection molding machine, forming in two stages, but the product is only produced once. This molding process, also known as dual material injection molding, is usually completed by a set of dual color molds and requires a dedicated dual color injection molding machine.

During the injection molding process, it should be noted that an injection mold is a tool for producing plastic products. It consists of several sets of parts, with a forming cavity inside this combination. During injection molding, the injection mold is clamped onto the injection molding machine, and the molten plastic is injected into the mold cavity, cooled and shaped inside the cavity. Then, the upper and lower molds are separated, and the product is ejected from the mold cavity through the ejection system. The dual color mold is then closed for the next injection molding, and the entire injection process is cyclic.
