Two-color High Gloss Plastic Injection Molding Products and the Applications in the Automotive Industry

With the development of present science and technology, the improvement of manufacturing level, and the continuous improvement of people's pursuit of automobile appearance quality and performance, two-color high-gloss injection molding products are widely used in automobile interior and exterior products. This advanced injection molding method provides brand new possibilities for the production of auto parts. 

The process of this two color injection molding can not only achieve the visual beauty of two different perceived colors on the same product, but also achieve the appearance quality of one material on the same product. And the other material achieves the advantages of internal structural performance. As a result, plastic injection molding products combine and complement each other in appearance quality and structural performance, showing excellent comprehensive performance.

Composition of the raw materials

1. PMMA material

Polymethyl methacrylate, also known as PMMA. It is a long-chain high molecular polymer, the main chain is -C-C-single bond structure, and the chain is soft. It has high mechanical strength, high surface gloss, excellent weather resistance, scratch resistance, chemical resistance and other outstanding comprehensive properties. Injection-molded products using PMMA as raw materials are increasingly used in the automotive industry. They are widely used in the production of automotive interior instrument decoration parts, front and rear door and window frame decoration outer panels, and automobile grille decoration parts.

2. ABS material

Acrylonitrile (A), butadiene (B), styrene (S) terpolymer (Acrylonitrile Butadiene Styrene plastic), referred to as ABS plastic. The performance of ABS combines the superiority of the three monomers, with comprehensive excellent performance such as high strength, high hardness and strong rigidity. At the same time, ABS plastic has practical production and processing meanings such as light weight, good molding, and easy coloring. So its application fields are continuously expanding in the automobile manufacturing industry. Automobile instrument panel frameworks, door panel frameworks, grille bodies and other auto parts manufactured using ABS particles as raw materials fully reflect the application of ABS plastics in the automotive field.
