Plastic Balls Manufacturer introduces the manufacturing process of plastic balls:
The first is that there should be no shrinkage of the plastic pellets during the injection process. Because the size of the plastic pellets is small, the rough balls shrink slightly, which is difficult to see with the eyes. If such a rough ball enters the grinding machine for grinding, it cannot Make the precision of the plastic ball round will cause the size of the plastic ball to be too small and affect the precision of the plastic ball.
Therefore, the temperature of the mold must be high during the injection molding of plastic balls. Only in this way, the blank balls will not shrink during injection molding. Plastic Balls Manufacturer can easily make a mistake when grinding plastic balls with a ball grinding machine. The error is that the pressure applied to the upper grinding plate of the ball grinding machine is too large. The disadvantage of excessive pressure is that the plastic ball will be deformed during the pressing process. If the grinding process is carried out under deformation, it is easy to cause the precision of the plastic ball to exceed Poor, it affects the precision and roundness of the plastic pellets, so when processing the plastic pellets, you should not put too much pressure on the ball grinding machine. Only under normal pressure can you process qualified plastic pellets.
