Engineering plastics granulation and color matching processing (mixing) is to fuse engineering plastics resin with color powder/masterbatch and extrude it into granular products through twin screw machine.

Advantages include:

- Easy to use

- Avoiding the environmental impact of toner

- The production process is easy to control and the distribution of color diffusion is better.

This process is suitable for products with higher color requirements or products with larger volume, especially for engineering plastics such as PC, PC/ABS, PA, etc. which have a wide range of applications. It requires higher processing performance. The stability of color performance can be guaranteed by the use of color matching service with granulation. Compared with the traditional method of adding color powder and masterbatch, this method is more worthwhile to choose.

Coloring process will change the physical and mechanical properties of plastics, especially engineering plastics.
