With the development of manufacturing, the requirements for plastic pepper balls are getting higher and higher. In addition to conventional plastic pepper balls, some customers sometimes purchase plastic pepper balls and plastic hollow pepper balls with special requirements. For example, some customers need plastic pepper balls to be magnetic and used in some high-precision sensors.

Because the solid plastic pepper ball is made by precision injection molding, it is impossible to add magnets to the solid plastic pepper ball from the manufacturing process, but the inside of the plastic hollow pepper ball is hollow, and the magnet can be put into the plastic hollow pepper ball. This manufacturing process can be realized by special equipment. Through several years of research and development and practice, our company has recently developed a plastic hollow pepper ball product with magnets inside. Magnetic plastic hollow pepper ball products have been applied to the oil level sensor of automobile fuel tank, and good results have been achieved. It is believed that more automobile parts customers will adopt the magnetic plastic hollow pepper ball scheme to manufacture liquid level sensor products.
