PP ball belongs to translucent plastic pepper ball, and its color is translucent, but the produced PP pepper ball sometimes turns yellow, which is caused by both material and production technology.
The main reason for the material is that when the plastic PP pepper ball is injected, an excessive amount of PP material is filled in the nozzle. The nozzle material has undergone a high temperature, and the physical properties of the material will change, and the color of the nozzle material itself will be yellow. After the raw material is added into the nozzle material, the injection processing will definitely make the color of the injected plastic PP ball yellow.
The main reason for the production process is that the temperature of the injection molding machine is too high when the blank of PP plastic pepper ball is injected, which causes the plastic material to age in the gun barrel of the machine, and the color of the plastic pepper ball is yellow, which is not only a problem of appearance, but also a great influence on the strength of the plastic PP pepper ball. Therefore, if you want to produce a beautiful plastic PP pepper ball, the temperature of the injection molding machine must not be too high, so as not to cause the color change of the plastic pepper ball.
