In our daily life, we can come into contact with a variety of plastic products of different colors. In injection molding, the color difference of injection molded products is also one of the common quality problems--Aberration of plastic injection molding parts , so why does the color difference occur? And how will we deal with it after the chromatic aberration occurs?
Aberration of plastic injection molding parts -raw materials
Because the raw material for injection molding is plastic, as a polymer plastic injection molding parts meterial, it is composed of synthetic resin and various plasticizers, stabilizers, lubricants, and pigments. In order to achieve different colors, colorants are usually used through masterbatch and colorants. The spread of powder forms different colors.
1. The toner or color masterbatch in the mixed color material is not completely diffused
2. The thermal stability, dispersibility, and covering ability of the dye are different
1. Clearly understand the characteristics of each plastic, increase the plasticizing pressure and screw speed. Increase the barrel temperature, increase the mold temperature
2. Pay attention to the shade of raw materials, especially when configuring white or light-colored plastics
3. Use raw materials with good light resistance, consider the formula according to its original color, and add a diffusing agent to the raw materials
1. The temperature of the injection molding machine
2. Pressure of the injection molding machine
3. Process of injection molding machine
4. Dust-free working environment
1. Regular maintenance of injection molding equipment
2. Set up a dust-free workshop, pay attention to the cleanliness of the environment at work
3. Maintain a stable injection molding process
