Plastic dyeing is an important part of the processing and production of plastic products, especially for some plastic products with special requirements, color differentiation is a very important content, so it is also very important to control the quality of plastic dyeing!

　　For plastic dyeing, there are three common methods:

　　1. Dry staining. Put a certain proportion of dye and plastic pellets into the rotating drum, and add 0.01% ~ 0.1% zinc stearate or white mineral oil as wetting agent to make the plastic easy to bond with the dye. Rotate the drum to completely mix the plastic and dye evenly.

　　2. Extrusion dyeing. The method is to mix the dye and plastic according to the dry dyeing method, and then squeeze them into a thin strip with a special extruder and cut them into granules. The method has good color mixing and is helpful to disperse poor pigments.

　　3. Dry dense dyeing. This method is basically the same as the extrusion dyeing method. The difference is that the proportion of dyes in plastics is more than 10 times higher than usual. During injection molding, multiple primary color plastics can be added to dilute it.

　　To understand the important content of plastic dyeing, ensure that plastic dyeing plays as usual and that the color will not be confused is to ensure the production quality of all kinds of plastic products. Only by firmly controlling one ring by one can we ensure the future development of the enterprise.
