Dual color molding injection molding process products

Dual color injection molding technology is an advanced plastic molding technology that can present two different colors or materials of plastic on the same product, bringing more flexibility and creative space to product design and manufacturing.

The principle of two-color injection molding process is achieved by using an injection molding machine with two or more injection units. Firstly, inject the first type of plastic material into a specific cavity of the mold to form the first layer of the product. This layer can be the main part of the product, or a part that serves as a basic support and other functions. For example, when manufacturing a two-color toothbrush, the first type of plastic may form the handle body of the toothbrush, and its material can be selected according to the product's requirements for hardness, elasticity, etc., to provide a good grip.

PRODUCT DETAILS

After the first layer of plastic is formed, the mold will rotate or slide to change the position of the cavity, and then inject the second type of plastic material. At this point, the second type of plastic will be molded based on the first type of plastic, which may cover the surface of the first layer or fill certain specific areas of the first layer. Continuing with the toothbrush as an example, the second type of plastic can be a softer thermoplastic elastomer, used to form a soft anti slip grip in some areas of the toothbrush handle body, or to form a soft bristle base at the toothbrush head.

OUR FACTORY

Our two-color injection molding process has many advantages. From the appearance, dual color molding can achieve rich and diverse color combinations and pattern designs, greatly enhancing the visual appeal of the product.

For example, the casing of some electronic products is cleverly integrated with fashionable color combinations and brand logos through two-color molding, enhancing the product's recognition. In terms of functionality, two-color molding can combine the characteristics of different plastics, such as combining hard and soft plastics, which can provide structural strength to the product while giving it a soft touch or good elasticity.

Modern industrial manufacturing

Moreover, compared to the traditional method of manufacturing different parts separately and then assembling them, the two-color injection molding process reduces the number of parts, lowers assembly costs, improves production efficiency, and enhances the overall integrity and sealing of the product.
