The plastic hollow pepper ball produced by hot-pressing technology of mold has the characteristics of high strength, good surface accuracy and no trace at the joint. However, sometimes the produced plastic hollow pepper ball has the problem of color difference between two pieces, which is mainly caused by not cleaning the injection molding machine when producing the semi-finished blank ball of plastic hollow pepper ball.

However, sometimes the produced plastic hollow pepper ball has the problem of color difference between two pieces, which is mainly caused by not cleaning the injection molding machine when producing the semi-finished blank ball of plastic hollow pepper ball.

The solution is to thoroughly clean the barrel of the injection molding machine when producing plastic hollow pepper balls, and it is best to have a special injection molding machine to produce semi-finished products of plastic hollow pepper balls, so as to really put an end to the problem of color difference between the two surfaces of plastic hollow pepper balls.
