Two-color toothbrush handle plastic injection mould

Nowadays, the styles of consuming products are ever-changing which not only require beautiful appearance and ingenious design, but also need to meet the market demand quickly. Designers generally use different materials in distinct purposes and parts of consuming products to meet the needs of specific environment, so as to extend product life, increase aesthetics and practicability. This practical design requirements will undoubtedly lead to the production technology to be complicated.  Two-color injection molding process is developed because of this trend. Manufacturers can create more designs to attract potential buyers.

The two-color toothbrush handles mold can realize the mixing processing of two kinds of plastic raw materials in a set of mold. After two times of molding respectively and then mixing together, the product with two kinds of raw material characteristics can be obtained. The products produced by the two-color toothbrush handles mould are more beautiful in appearance than the ordinary toothbrushes. We can greatly reduce product deformation, production time and production cost by using two-color injection technology. The handle of the two-color toothbrush is made of PP and TPE; it not only maintains the characteristics of firmness and durability, but also increases the soft and comfortable feeling.

Most two-color toothbrush handles are made by plastic injection molds with rotating core. The rotating core process means that the two-color plastic injection mold is not rotated by the injection molding machine. 

Of course, the two-color toothbrush handles mold design and structure are more complicated than the single-color mold. The rotating core should have high quality and durability to ensure mold performance and quality. At the same time, the full hot runner of each cavity is considered to improve the surface quality of two-color toothbrush handles. Generally speaking, extensive experience in mold design and two-color plastic injection molds making is very important for obtaining high-quality two-color plastic products.
