TPU plastic hollow pepper ball is also called polyurethane hollow pepper ball. Because of its excellent elasticity and wear resistance, TPU plastic hollow pepper ball is widely used in some fields such as sealed pipe fittings and valves that need to be used for a long time. However, the high production cost of TPU plastic hollow pepper ball also restricts its market application.The manufacture of TPU plastic hollow pepper balls is quite different from that of PP plastic hollow pepper balls. PP plastic hollow pepper balls are manufactured by blow molding technology, while TPU plastic hollow pepper balls are manufactured by in-mold high-temperature fusion technology. Compared with the TPU plastic hollow pepper balls manufactured by blow molding technology, they have high precision and high strength, and the wall thickness of TPU plastic hollow pepper balls can be manufactured as required. It can be realized from 1.0mm-3mm to 3 mm, and the precision is high: the plastic blank hollow pepper ball produced by in-mold high-temperature fusion technology can be processed into a precise TPU plastic hollow pepper ball with the precision within ±0.01mm after being ground by a special plastic ball grinder. At present, this production technology is also a unique patent technology of Dongguan Jiaji Plastic Products Co., Ltd. 。
