The manufacturing principle of foamed plastic pepper ball is to add a certain proportion of foaming agent into plastic raw materials. Because the foaming of foamed plastic pepper ball is uncontrollable in the molding process, some defects will appear in foamed plastic pepper ball. To improve the yield of foamed plastic pepper ball, it is necessary to find out the reasons for the defects, and then find a solution according to the original drawings of the defects.

The appearance of plastic foamed pepper balls is bad, which is mainly reflected in the yellow color of the foamed pepper balls. The bad original picture is that the temperature of the machine is too high, resulting in coking and discoloration of the foaming agent. The improvement method is to adjust the temperature of the injection molding machine. Generally speaking, different foaming agents have different temperature requirements for the injection molding machine, so when buying foaming agents, you should match the appropriate foaming agent according to the injection temperature of plastic materials.

The internal foaming of plastic foamed pepper ball is uneven, which is caused by the insufficient mixing of foaming agent and plastic material. Because the foaming agent is powder, it is easy to concentrate in the gaps in the plastic material and enter the injection molding machine, while the rubber material on it has poor foaming because there is no foaming agent. This leads to the bad phenomenon of uneven foaming inside the plastic pepper ball. The improvement method is to add special mixing AIDS when the raw materials and foaming agents are mixed to help the plastic materials and foaming agents stick together. After the raw materials and foaming agents are mixed, the phenomenon of uneven foaming is improved.
