TPU plastic pepper ball is also known as polyurethane hollow ball. TPU hollow ball is widely used in some fields such as sealed pipe fittings and valves that need long-term use because of its excellent elasticity and wear resistance. However, the high production cost of TPU plastic pepper ball also restricts its market application.

There is a great difference between the manufacture of TPU plastic hollow balls and PP hollow balls. PP plastic hollow balls are manufactured by blow molding process, while TPU plastic pepper balls are manufactured by in-mold high-temperature fusion technology. Compared with the TPU plastic pepper balls manufactured by blow molding process mold high-temperature fusion technology, they have high precision and high strength. The wall thickness of TPU plastic pepper balls can be manufactured as required, from 1.0mm-3mm to 3 mm. High precision: The hollow plastic ball produced by in-mold high-temperature fusion technology can be ground by a special plastic ball grinding machine, and then the precision TPU plastic empty pepper ball with the precision within ±0.01mm can be processed. At present, this production technology is also a unique patented technology of Dongguan Jiaji Plastic Products Co., Ltd. 。
