The main characteristics of plastic pepper balls for ornaments are bright colors and beautiful appearance. In order to achieve these two points, the special toner for plastic products should be used to adjust the color, and there are also two-color plastic pepper balls that can be often seen in plastic pepper balls for ornaments. So what technology is used to manufacture the two-color plastic pepper balls?

The simplest manufacturing method of bicolor plastic pepper ball is to use bicolor injection molding machine. Generally speaking, it is a back mold and two front molds for injection production. The injection molding machine uses a special bicolor injection molding machine with two sets of hoppers and barrels. When the first injection is completed, the front mold of the injection molding machine rotates quickly, and the other front mold is closed to the back mold, and then the second injection is carried out. Because the first injection time is very short, the rubber material injected for the second time can be very good.
